Glimsy Terms of Use

Effective date: 31 August 2026
Version: 2.0 (supersedes the Terms of Use of 9 July 2026)

These Terms are made available in Polish and in English. In the event of any discrepancy between the language versions, the Polish version prevails. This reservation does not limit any consumer rights arising from mandatory provisions of the law of the consumer's country of habitual residence.

1. General provisions

1.1. These Terms set out the rules for using the Glimsy application (the Application) and constitute the terms of service for the electronic provision of services.

1.2. The service provider and owner of the Application is:

GLIMSY spółka z ograniczoną odpowiedzialnością (a Polish limited liability company)
ul. Zapłocie Duże 223A, 43-300 Bielsko-Biała, Poland
KRS 0001260619 · NIP 5472262046 · REGON 545480191

(the Provider). Contact: support@glimsy.app

1.3. These Terms apply to the Application on Android and iOS devices and to the web version.

1.4. By starting to use the Application, the user accepts these Terms. Anyone who does not accept them should not use the Application.

1.5. These Terms are to be read together with the Privacy Policy and the Refund Policy, which form an integral part of them.

2. Nature of the service

2.1. The Application is used for studying with flashcards. It allows decks and flashcards to be created, user content to be stored, reviews to be scheduled with the FSRS algorithm, material to be imported from external files, decks to be shared with other users and — within paid plans — artificial-intelligence features to be used.

2.2. The Application works offline first: core functions, including studying and creating content, are available without an internet connection. The exception is functions that inherently require connectivity — in particular the AI features, purchasing a paid plan and deleting an account.

2.3. The Application is educational and supportive in nature. It does not constitute professional advice, including legal, medical or financial advice.

2.4. Technical requirements. Using the Application requires:

a) a device running Android or iOS in a version supported by the Application — the minimum supported version is stated on the Application's listing in Google Play and the App Store — or an up-to-date web browser with JavaScript and browser local storage enabled;
b) an internet connection — for the first sign-in, for synchronising data across devices and for the functions that inherently require connectivity (the AI features, purchasing a paid plan, deleting an account); the remaining functions work without a connection, in accordance with point 2.2;
c) an active e-mail address and an account created in accordance with section 3.

The digital content made available in the Application — decks, flashcards, media and the results of the AI features — is presented and stored in formats specific to the Application and is intended for use within it. The Provider does not warrant that the Application will interoperate with hardware or software other than that indicated above. Importing material from external files covers the formats indicated in the Application at the place where the import begins.

2.5. Specific risks. The Provider informs users that the use of services provided by electronic means involves risks typical of telecommunications networks, in particular: malicious software, attempts to obtain login credentials by deception (phishing), interception of transmissions on unsecured public networks, and unauthorised access to a device or account as a result of a password being disclosed to a third party. These risks do not arise from the operation of the Application but from the nature of the network itself. Users are advised to keep their software up to date, to use a unique password and a device screen lock, and not to open messages impersonating the Provider — the Provider never asks for a password.

3. User account

3.1. Use of some functions requires an account to be created — by e-mail address and password, through a Google account or through an Apple ID.

3.2. Access to data requires the e-mail address to be confirmed.

3.3. The user is responsible for keeping their sign-in credentials confidential and for the actions performed on their account.

3.4. One account is intended for use by one person. Sharing sign-in credentials with third parties, sharing an account and reselling access are not permitted.

4. Age of the user

4.1. The Application is aimed broadly at pupils and students.

4.2. Persons below the age required to consent independently to the processing of personal data under the law of their country (as a rule, below 16 in the European Union) may use the Application only with the consent of a parent or legal guardian.

4.3. The Application is not directed to children under 13 within the meaning of United States law (COPPA).

4.4. Purchase of a paid plan by a minor. By purchasing a paid plan, the user declares that they:

a) have full legal capacity, or
b) have limited legal capacity and have obtained the consent of their statutory representative (a parent or legal guardian) to enter into the contract, or
c) are making the purchase from funds placed at their free disposal by their statutory representative, within the limits in which the law permits such funds to be disposed of independently.

This declaration is made when confirming the purchase, together with the declaration referred to in point 5.9.2.

The Provider notes that, under the Polish Civil Code, a contract entered into by a person with limited legal capacity without the required consent of their statutory representative becomes valid only once the representative confirms it. A statutory representative who finds that a contract was concluded without their consent may refuse to confirm it — the contract is then invalid and the fee paid is refundable. Please send such notifications to support@glimsy.app.

5. Paid plans, payments and billing

5.1. Freemium model

The basic range of functions — creating decks and flashcards, studying, data synchronisation — is available free of charge, within the limits of the free plan. Extended functions, in particular the AI features, higher limits and material import, are available in the paid Silver and Gold plans, offered either as a renewing subscription or as a one-off purchase for a fixed period.

Current prices, limits and plan scope are presented on the pricing page and in the Application before a purchase is made.

5.2. Where purchases are made

Paid plans are purchased and managed in the web version of the Application. The mobile applications reflect the plan status of the signed-in account and make its features available, but are not used for making purchases.

5.3. Merchant of record — Stripe

5.3.1. Payments are handled under the Stripe Managed Payments model. This means that the merchant of record is Stripe, not the Provider.

5.3.2. Consequently:

• the card statement shows the descriptor LINK.COM*, and the transaction is described as "Sold through Link";
• receipts and invoices are issued by Stripe; the entity shown on the document is, as a rule, Sold through Link, LLC, and in countries not covered by Stripe's tax settlement — the Provider;
• VAT is calculated, collected and remitted by Stripe, including in Poland and throughout the European Union;
• transactional messages — receipts, invoices, refund confirmations and some subscription notifications — are sent by Stripe;
• payment disputes (chargebacks) are handled by Stripe on its own account;
• the user is given access to a Link account, where they can review orders, cancel the subscription and change the payment method and billing details.

5.3.3. The Provider remains the provider of the service. It is responsible for its content, quality, availability and substantive support, handles reports concerning the operation of the Application and decides whether a refund is warranted under the rules set out in the Refund Policy. The contract for the electronic provision of services is concluded between the user and the Provider.

5.3.4. The Provider does not receive and does not store full payment card details. The rules for processing payment data are described in the Privacy Policy.

5.4. Prices and taxes

Prices are presented in Polish zloty (PLN) and United States dollars (USD). For customers settling in other currencies, Stripe may present a price converted into the local currency. The total price together with the billing period is presented before the purchase is confirmed. Prices include applicable tax, settled by Stripe at the rate applicable to the consumer's country.

5.5. Subscription and automatic renewal

The subscription is renewing. Unless cancelled, it renews automatically for the next billing period (monthly or yearly) and the selected payment method is charged again. The renewal price, the currency and the renewal frequency are presented before the purchase is confirmed, and starting a subscription requires the user's express consent.

5.6. Cancellation

The user may cancel the subscription at any time, without giving a reason and without contacting support — in the Application or in the Link account. After cancellation, access to paid features is retained until the end of the paid period, and no further charges are made. A scheduled cancellation and the access end date are visible in the Application.

5.7. One-off purchases

A one-off purchase provides access to a paid plan for one defined period and does not renew automatically. No payment method is stored for future charges and there is nothing to cancel — access expires at the end of the paid period.

5.8. AI credits

5.8.1. Use of the AI features is settled in credits granted together with the plan. The number of credits assigned to each plan is presented on the pricing page.

5.8.2. Credits are granted for a billing period and do not carry over to the next one. In the yearly plan, credits are granted in twelve monthly tranches.

5.8.3. A credit is reserved before an operation is performed and settled once it finishes. If the operation fails for technical reasons attributable to the Provider, the credit returns to the pool. If the operation is rejected because of invalid input or because limits have been exceeded, the credit is forfeited. If the operation is rejected by the security mechanisms as an attempted abuse, the credit is forfeited deliberately, as the cost of that attempt.

5.8.4. Credits are not a means of payment, are not exchangeable for money except in the cases set out in the Refund Policy, and may not be transferred between accounts or resold.

5.9. Right of withdrawal

5.9.1. A consumer, as well as a trader using the Application on consumer terms, has the right to withdraw from a distance contract within 14 days without giving a reason.

5.9.2. Because access to paid features is made available immediately after purchase, before proceeding to payment the user is asked in the Application to expressly request that performance begin before the withdrawal period expires and to confirm that they acknowledge the consequences.

5.9.3. The consequences are as follows: the user retains the right of withdrawal; on withdrawal they will pay an amount proportionate to the performance rendered up to the moment of withdrawal, covering the period of access used and the AI credits used; the right of withdrawal expires once the service has been fully performed, that is, at the end of the paid period.

5.9.4. Withdrawal is notified to support@glimsy.app. No form and no justification are required.

5.10. Refunds and complaints

The rules on refunds are set out in the Refund Policy. In short: a refund is available where it was technically impossible to use the AI features; it is not available on the ground of dissatisfaction with the quality of AI-generated content. Receiving a refund — including a partial one — means the end of paid access.

The above does not prejudice the consumer's statutory rights, including rights arising from a digital service's lack of conformity with the contract.

5.11. Price changes

The user will be informed with appropriate notice of any change to the subscription price applicable to the next billing period. The change does not affect a period already paid for. If the user does not accept the new price, they may cancel the subscription before it renews.

5.12. Changing plans and returning to the free plan

5.12.1. An upgrade takes effect immediately; where a subscription is active, the price takes into account the value of the unused credits of the current period. A downgrade takes effect from the beginning of the next billing period.

5.12.2. User content is never deleted as a result of a plan change or a plan ending. Decks, flashcards, study history and uploaded files remain available.

5.12.3. If, after returning to the free plan, the number of decks or flashcards exceeds that plan's limits, the user cannot create new decks or flashcards until they fall below the limit or purchase a plan. Browsing, studying, editing and deleting remain available without restriction — in particular, exceeding a limit never blocks deletion.

6. Artificial intelligence features

6.1. Prototype status

6.1.1. The AI features are a prototype. They are available only in paid plans and require separate, explicit consent given in the Application. Consent may be withdrawn at any time.

6.1.2. The Provider makes every effort to ensure that generated content is of the highest possible quality, that the system does not create inappropriate content, and that it is resistant to abuse and prompt manipulation attempts. To that end it applies multi-layered filtering, moderation and control mechanisms, described in general terms in the Privacy Policy.

6.1.3. The application of these measures is not a guarantee. Given the nature of language models, the Provider cannot ensure that generated content will be correct, complete, up to date, free of errors or suitable for the user's purpose. The user uses AI-generated content at their own risk and should verify it before relying on it.

6.1.4. The Provider is not liable for AI-generated content or for the consequences of its use, to the fullest extent permitted by law and subject to point 13.4.

6.2. Availability

6.2.1. The Provider makes every effort to keep the AI features continuously available.

6.2.2. The AI features rely on the services of external model providers. Their temporary unavailability may result from chance events, outages, technical breaks, restrictions imposed by a provider or software errors — including matters beyond the Provider's control. The Provider does not guarantee uninterrupted availability of the AI features.

6.2.3. Where it was technically impossible to use the AI features, the user may be entitled to the rights set out in the Refund Policy.

6.3. Rights to AI-generated content

6.3.1. The Provider claims no rights to decks, flashcards or other material generated using the AI features in the Application. That material is not the property of the Provider.

6.3.2. To the extent that any copyright or related rights would arise on the Provider's side in the results of generation, the Provider transfers them to the user — free of charge, without territorial or time limits, on all fields of exploitation known at the moment of generation, together with the right to authorise the exercise of derivative rights and the right to use the material for commercial purposes. The transfer takes place at the moment the result is generated.

6.3.3. Should the transfer referred to in point 6.3.2 prove ineffective or impermissible for any reason, the Provider grants the user, to the same extent, an exclusive, royalty-free licence unlimited in territory and time, with the right to grant sub-licences and to authorise the exercise of derivative rights, and undertakes not to exercise any rights in those results against the user.

6.3.4. The user acknowledges that the legal status of machine-generated content is not settled. Under copyright law, a work is a manifestation of creative activity of an individual character — that is, the result of human activity. Material produced solely by the operation of a model, without a human creative contribution, may not be a work at all — in which case no copyright belongs to anyone, including neither the Provider nor the user. Rights may, however, belong to the user in respect of their own creative contribution: the content of the prompt, the selection and arrangement of the material, the editing performed and the source material supplied. Points 6.3.2 and 6.3.3 apply only to the extent that rights actually arise.

6.3.5. The use of generation results is also subject to the terms of the model providers the Provider uses. The current list of providers is contained in the Privacy Policy. The Provider is not a party to those terms on the user's behalf, cannot modify their content and cannot ensure that they will not change.

6.3.6. The Provider makes no representations or warranties that generated content is original, that it is protected by copyright, that the user will acquire any rights in it, or that its use — including commercial use — will not infringe third-party rights. It is for the user to verify whether the intended use is permissible.

6.3.7. The user is responsible for source material. By submitting a file for AI processing, the user declares that they are entitled to use it for that purpose. Material generated on the basis of someone else's work may constitute a derivative work, the dissemination of which requires the rights holder's consent. This applies in particular to sharing such decks with other users under section 8.

6.4. Labelling AI-generated content

6.4.1. The Provider informs the user that they are communicating with an artificial intelligence system and that content produced with it is machine-generated content. This information is presented in the Application before the AI features are first used and while they are being used.

6.4.2. The obligation to mark content produced by an artificial intelligence system as machine-generated rests on the Provider, as the entity making that system available under its own name. The Provider discharges it by marking, in its own records, every deck created with the AI features with the permanent marker referred to in point 6.4.3.

6.4.3. A deck created with the AI features receives a permanent provenance marker. The marker cannot be removed or switched off — including after the user has rewritten the content — because it serves to discharge the obligation referred to in point 6.4.2, and a marker that could be taken off would not fulfil its purpose. The marker does not limit the user's rights to the content or the way it may be used.

6.4.4. A user who disseminates content generated in the Application outside it — in particular by publishing it or making it available to third parties — may be subject to additional obligations to label such content, arising from the rules applicable to the manner and place of dissemination. Those obligations do not replace the Provider's obligations set out in point 6.4.2.

6.5. Restrictions on the use of AI

It is prohibited to use the AI features to generate unlawful content, to attempt to circumvent security mechanisms, to use the Application in an automated manner outside its interface, or for the activities described in section 9.

7. User content

7.1. The user may add their own content to the Application: decks, flashcards, images and audio files.

7.2. The user declares that they hold the rights to the content they post or the appropriate consents and licences.

7.3. The user retains the rights to their content. They grant the Provider a non-exclusive, royalty-free licence unlimited in territory solely to the extent necessary to provide the service — recording, displaying, synchronising, creating technical copies and passing content to model providers in order to perform an operation the user has requested. The licence expires when the content or the account is deleted, except for technical copies during the deletion process.

7.4. The Provider does not review every item of content before it is stored — in this respect it provides a hosting service — and is not liable for content entered by users.

7.5. The Application is not an archiving service for critical data. Users are advised to keep their own backups of important material.

8. Sharing decks

8.1. The user may share their own deck by generating a sharing code. Use of this feature is voluntary.

8.2. A person holding the code sees the deck name, its description and the number of flashcards, and after using the code receives their own copy of the deck together with its flashcards and media.

8.3. From the moment a deck is shared, its basic details become visible to every signed-in and verified user of the Application, not only to the person given the code. The content of the flashcards remains inaccessible until the code is used.

8.4. A copy made by the recipient becomes their data. Later switching off sharing or deleting the source deck does not remove the copy from the recipient's account.

8.5. Sharing can be switched off at any time — the code then stops working.

8.6. By sharing a deck, the user declares that they are entitled to disseminate the content it contains. Sharing material to which the user does not hold rights is a breach of these Terms.

9. Prohibitions and abuse

9.1. The following are prohibited in particular:

a) posting unlawful content or content infringing copyright, patents, trade secrets or the personal rights of third parties;
b) posting offensive or pornographic content, or content inciting hatred, violence or discrimination;
c) attempting to circumvent security measures, or interfering with the operation of the Application or its infrastructure, including reverse engineering, automated abuse and automated data scraping;
d) using the Application in a manner liable to disrupt its operation or expose other users to risk;
e) sharing an account, reselling access, and reselling or transferring AI credits.

9.2. Obtaining AI credits without payment

9.2.1. Any knowing act aimed at obtaining AI credits or access to paid features without paying the fee due is prohibited, in particular:

a) exploiting an error, vulnerability or malfunction of the Application, its security measures or the payment process;
b) manipulating requests sent to the service, including substituting order, price, plan or identifier parameters;
c) circumventing entitlement gates, rate limits or the credit settlement mechanism;
d) creating accounts in order to make repeated use of the limits assigned to the free plan or to promotional periods;
e) manipulating the prompt sent to the model in order to circumvent security measures or obtain performance beyond the applicable scope;
f) raising a payment dispute or a refund request in bad faith while continuing to use the service.

9.2.2. Detection of such conduct may result in: forfeiture of the credits used in connection with the breach, withdrawal of access to paid features, suspension or permanent blocking of the account, refusal of a refund, and pursuit of compensation for the damage caused.

9.2.3. The Provider operates mechanisms for detecting such attempts. Repeated breaches may lead to temporary blocking of access to the AI features.

9.2.4. This point does not apply to acts undertaken in good faith in accordance with section 10.

10. Reporting vulnerabilities

10.1. A user who discovers an error, a vulnerability or a way to obtain AI credits or access to paid features without payment is required to inform the Provider without delay at support@glimsy.app.

10.2. The report should contain a description of the problem discovered and — where possible — how to reproduce it.

10.3. Until the problem is fixed, the reporter is required not to exploit it beyond what is necessary to confirm that it exists, not to disclose information about it to third parties or publicly, and not to access other people's data.

10.4. Against a person who makes a report in good faith and observes the above rules, the Provider will not pursue liability for the mere discovery and confirmation of the vulnerability, nor will it apply the sanctions set out in point 9.2.

10.5. Knowingly exploiting a discovered vulnerability for one's own benefit, reselling it or disclosing it before it is fixed is a gross breach of these Terms and forfeits the protection under point 10.4.

11. Reporting unlawful content

11.1. The Provider respects intellectual property rights. Please send reports concerning content that infringes the law or these Terms to support@glimsy.app, indicating the content, its location and the basis of the report. The report should include the reporting party's contact details, unless it concerns an offence against sexual freedom or decency.

11.2. The Provider confirms receipt of the report without undue delay to the address given and informs the reporting party of the decision taken, together with its reasons. That information states whether automated means were used in handling the report. A reporting party dissatisfied with the decision may respond to it at the same address and, independently of that, may pursue judicial redress.

11.3. The Provider may remove user content or block access to it without prior notice upon receiving credible notice of its unlawful character. A user whose content is affected by such a decision is informed of it in accordance with point 17.3.

12. Service availability

12.1. The Provider makes efforts to ensure that the Application works correctly, but does not guarantee uninterrupted availability or the absence of errors.

12.2. The Provider may introduce updates, functionality changes and temporary technical breaks necessary to maintain the system.

12.3. The Provider may require the Application to be updated to a supported version. Use of an out-of-date version may be restricted for security and compatibility reasons.

13. Disclaimer of liability

13.1. No guarantee of results. The Application is educational and supportive in nature. The Provider does not guarantee the substantive correctness of content created by users or generated by AI, or that any learning outcome will be achieved.

13.2. Backups. The Provider is not liable for the loss of data, study progress or created decks as a result of technical failures, attacks, the acts of third parties or accidental deletion by the user.

13.3. Limitation of liability. The Application is made available "as is". To the fullest extent permitted by law, the Provider is not liable for indirect or consequential damage, lost profits or loss of data.

13.4. Consumers. The limitations of liability contained in these Terms apply to consumers only to the extent permitted by mandatory provisions of law. Liability for damage caused intentionally, for personal injury, and any liability that cannot be excluded by law, is neither excluded nor limited.

14. Indemnity

The user undertakes to hold the Provider harmless and to cover reasonable costs, including legal costs, arising from: the user's breach of these Terms; infringement of third-party rights, including copyright and the right to privacy; claims relating to content posted or shared by the user, including source material submitted to the AI features. This provision does not apply to consumers to the extent that it would be contrary to mandatory provisions of law.

15. Privacy

The rules on the processing of personal data are described in the Privacy Policy. These Terms are to be read together with it.

16. Relationship with Apple and Google

16.1. These Terms are concluded solely between the user and the Provider, not with Apple Inc. or Google LLC. Those entities bear no responsibility for the Application, its content or its maintenance.

16.2. Paid plans are not purchased through the App Store or Google Play. Purchases take place in the web version of the Application, on the terms described in section 5.

17. Ending use

17.1. The user may delete their account at any time in the Application settings. The operation requires an internet connection. The scope of the data deleted is described in the Privacy Policy.

17.2. Deleting an account does not automatically trigger a refund of the fees for the current period — the Refund Policy and point 5.9 apply.

17.3. The Provider may restrict access to the Application, remove content or block an account in the event of a breach of these Terms, abuse or a legal obligation. Unless this would impede protection against abuse or is precluded by law, the user receives a statement of reasons for the decision, covering:

a) what the decision concerns — content, a feature or the account — and its territorial scope and duration, or a statement that it is indefinite;
b) the factual and legal grounds, including the provision of these Terms concerned;
c) whether the decision was taken using automated means, including mechanisms based on artificial intelligence;
d) information on redress — the user may respond to the decision by writing to support@glimsy.app and, independently of that, may pursue judicial redress.

17.4. Access to paid features may also end as a result of a refund, a payment dispute or a data deletion request addressed by the user directly to Stripe — Stripe will then cancel the subscription.

18. Changes to the Terms

18.1. The Provider may amend these Terms for important reasons: a change in the scope or manner of providing the service, a change in legislation, a change of providers, security considerations or organisational changes on the Provider's side.

18.2. Users will be informed of any change with appropriate notice — by a message in the Application or in another appropriate manner. A change does not affect rights acquired in a period already paid for.

18.3. A user who does not accept a change may cancel the subscription before it takes effect and delete their account.

19. Governing law and dispute resolution

19.1. The governing law is Polish law. This choice does not deprive a consumer of the protection afforded by mandatory provisions of the law of their country of habitual residence.

19.2. Complaints sent to support@glimsy.app are dealt with within 14 days.

19.3. A consumer may use out-of-court complaint handling and redress procedures, in particular:

a) seek free assistance from a municipal or district consumer ombudsman (in Poland);
b) refer the matter to a permanent arbitration court operating at a provincial inspectorate of the Trade Inspection, or apply for mediation proceedings before a provincial Trade Inspection inspector;
c) use the information available on the website of the Polish Office of Competition and Consumer Protection (uokik.gov.pl);
d) for consumers from other European Union countries — contact the European Consumer Centre.

Use of these procedures is voluntary and requires the agreement of both parties. The European Online Dispute Resolution (ODR) platform ceased operating on 20 March 2025, and the regulation establishing it was repealed with effect from 20 July 2025; references to it are no longer current.

19.4. Disputes with users who are not consumers are resolved by the court having jurisdiction over the Provider's registered office.

20. Severability

The invalidity or ineffectiveness of any provision of these Terms does not affect the validity of the remainder. An invalid provision is replaced by the applicable provisions of law, preserving the parties' intention to the fullest extent possible.
