LangPal Terms of Service
Effective date: 1 October 2026
Version: 2.0
For accounts created before 1 October 2026, this document applies from 15 October 2026; until then the previous version applies.
1. General
1.1. These Terms govern the use of LangPal — a service for learning foreign languages by collecting vocabulary and studying it — available as a web app (app.langpal.ai), iOS and Android apps and a browser extension (together, the “Service”).
1.2. The Service is provided by CodeYourBrand Sp. z o.o., with its registered office at Al. Jerozolimskie 109/70, 02-011 Warsaw, Poland, Tax ID (NIP): PL5273088516, National Court Register (KRS): 0001073645, share capital: PLN 10,000.00 (the “Provider”, “we”).
1.3. Contact for all matters, including complaints: support@langpal.ai.
1.4. By creating an account you enter into a contract with us for the supply of digital services under these Terms. The processing of personal data is described in the Privacy Policy.
1.5. In these Terms: “User” (“you”) means a person using the Service; “Consumer” means a User who is a natural person using the Service for purposes not directly related to their trade, business or profession, as well as a natural person to whom Polish law grants consumer rights; “User Content” means everything you save in the Service (entries, sets, notes); “Pro Plan” means the paid subscription.
2. Requirements
2.1. The Service may be used by people aged 16 or over. People without full legal capacity need the consent of their legal representative to enter into the contract, in particular to buy the Pro Plan.
2.2. To use the Service you need: a device with internet access, an up-to-date browser (Chrome, Edge, Safari or Firefox released within the last two years) or a device running a version of iOS or Android supported by the app, and an email address or a Google or Apple account. Voice mode requires a microphone.
2.3. One person may hold one account. You are responsible for keeping your sign-in details confidential and for activity carried out from your account.
3. The Service
3.1. The Service lets you, among other things: save words, phrases and sentences in sets; enrich them with translations, definitions and examples; study them with a spaced-repetition system; and capture vocabulary from web pages and video subtitles through the browser extension and the mobile app.
3.2. The Free Plan includes an unlimited number of entries, sets and folders, the full study system, one learned language, capture of selected words in the extension, and 40 AI operations per calendar month.
3.3. The Pro Plan additionally includes:
- 800 AI operations per calendar month (see section 4);
- Conversation mode (a written and spoken dialogue with an AI partner);
- any number of learned languages;
- connection to external AI assistants;
- highlighting of known words on pages and vocabulary capture from YouTube subtitles in the extension.
3.4. Features may change. Changes that would materially reduce a paid Pro Plan are made in accordance with section 14.
3.5. The Service may include features marked as experimental; they may be unstable and may be withdrawn.
4. AI operations and fair use
4.1. An AI operation is any request to a feature that uses an external model: translating and looking up meanings, filling in the fields of an entry, generating a single field, explaining a form, listening to a pronunciation, recognising speech, and each turn in Conversation mode together with its pronunciation.
4.2. An operation counts even when the answer comes from a cache. An operation that fails because of an error on our side does not count.
4.3. The allowance renews on the first day of each calendar month at 00:00 UTC. Unused operations do not carry over. You can see the current counter in settings.
4.4. On the Free Plan, once 40 operations are used, AI features are unavailable until the allowance renews. All other features continue to work.
4.5. On the Pro Plan, the 800-operation allowance is a fair-use threshold, not a cut-off. Once it is exceeded, AI features keep working, but answers may be generated by a lighter model, which may reduce their level of detail. We notify you in the Service as you approach the threshold. After 2,400 operations in a month, AI features are paused until the allowance renews; if that happens, write to us — we then look for an individual solution.
4.6. Limits exist to prevent abuse and to keep the Service working well for everyone. Circumventing them — including by creating multiple accounts or calling features in an automated way — is not allowed.
5. AI features — important notices
5.1. Translations, definitions, examples, explanations, memory aids, your partner’s lines in Conversation mode, assessments of what you say, and pronunciation recordings are generated automatically by artificial-intelligence models. They may contain errors, inaccuracies or unsuitable content. You approve generated entry content yourself before it is saved. Where a mistake matters (an exam, work, documents), verify it against another source.
5.2. The Service is a tool that supports self-study. It is not a language course, does not guarantee that you will reach a particular level or pass an exam, and does not issue certificates.
5.3. Using AI features requires your consent to sending request content to the providers named in the Privacy Policy. Without consent the Service works without AI features.
5.4. You can report AI-generated content you consider inappropriate in the Service or at support@langpal.ai.
6. Payments and subscription
6.1. The Pro Plan is an automatically renewing subscription, billed monthly or yearly. Current prices — tax included — are shown in the Service before purchase, in the currency assigned to your account (PLN or USD). On the effective date of these Terms they are: USD 4.99 per month or USD 39.99 per year; PLN 18.99 per month or PLN 148.99 per year.
6.2. Payments for purchases on the website are processed by Stripe. The seller is the Provider. You give your card details directly to the payment processor — we have no access to them. You receive an invoice or payment confirmation by email.
6.3. The subscription renews automatically for a further period of the same length, and the fee is charged in advance to your saved payment method, until you cancel.
6.4. Cancelling. You can cancel at any time in settings (“Plan → Manage subscription”). Cancellation takes effect at the end of the paid period: you keep the Pro Plan until that day, and no fee is charged for the next period.
6.5. Failed payment. If a renewal payment fails, the payment processor retries for about 3 weeks; during that time you keep the Pro Plan. If the retries are unsuccessful, the account returns to the Free Plan.
6.6. After the Pro Plan ends you keep all your Content and study progress. Additional learned languages become available for reading and study only; you can save in one language of your choice. Pro-only features are no longer available.
6.7. Price changes. We will tell you about a change to the price of your subscription by email at least 30 days before the renewal it applies to. If you do not accept the new price, you can cancel before the renewal.
6.8. Refunds. Fees for a billing period that has started are non-refundable, except where a refund is required by mandatory law — in particular under the right of withdrawal (section 7) and our liability for lack of conformity of the service (section 12).
6.9. Deleting your account while a subscription is running ends it immediately, with no refund for the current period — we tell you so before you confirm deletion.
7. Right of withdrawal (Consumers)
7.1. A Consumer may withdraw from a distance contract within 14 days of concluding it, without giving a reason. This applies both to creating an account and to buying the Pro Plan.
7.2. Loss of the right of withdrawal when buying the Pro Plan. We activate the Pro Plan immediately after payment. Before purchase we therefore ask for your express consent to performance beginning before the withdrawal period ends, and for your acknowledgement that once the service has been performed — that is, once the Pro Plan has been made available — you lose the right of withdrawal (Article 38(1)(13) of the Polish Consumer Rights Act of 30 May 2014; Article 16(m) of Directive 2011/83/EU). Without that consent the purchase cannot be made. We confirm your consent on the invoice emailed to you after purchase.
7.2a. The consent in section 7.2 is at the same time your express request that performance begin before the withdrawal period ends. If, in a particular case, the right of withdrawal applies despite that consent and you exercise it, you pay for what was provided up to the moment of withdrawal — an amount proportionate to the period for which the Pro Plan was available, calculated from the price of the paid period (Article 35 of the Polish Consumer Rights Act; Article 14(3) of Directive 2011/83/EU). We refund the rest.
7.3. Where the right of withdrawal applies, it is enough to send an unambiguous statement to support@langpal.ai before the deadline — you may use the form in Annex 1. We refund the payment without undue delay and no later than 14 days, using the same payment method.
7.4. You can stop using a free account at any time by deleting it (section 13.1).
8. App store purchases
8.1. On the effective date of these Terms, the mobile apps do not offer the Pro Plan for purchase. Pro Plan features are available in the web app (app.langpal.ai) and in the browser extension on a computer. In the mobile apps — including the Safari extension installed together with the iOS app — your account works within the scope of the Free Plan, even if the Pro Plan was bought on the website.
8.2. If we make the Pro Plan available for purchase in the App Store or Google Play, the following will apply:
- payment is charged to your Apple ID account or Google account at confirmation of purchase;
- the subscription renews automatically unless it is turned off at least 24 hours before the end of the current period; the renewal fee is charged within 24 hours before the end of the period;
- you manage and cancel the subscription in your App Store or Google Play account settings — we cannot do this for you; deleting your LangPal account does not cancel such a subscription;
- refunds for store purchases are handled by Apple or Google respectively, under that store’s rules.
9. User Content and licence
9.1. User Content remains yours. You grant us a non-exclusive, royalty-free licence to store, process and display it solely to the extent needed to provide the Service — including sending request content to AI providers with your consent. The licence ends when the Content or the account is deleted.
9.2. Shared cache. Dictionary look-up results and pronunciation recordings are shared between users in a form not linked to any account (details: Privacy Policy). You agree that an answer generated for your query may serve another user asking the same thing.
9.3. Sharing sets. By creating a public link to a set, you allow anyone who has it to view the set and copy it to their own account. You can revoke the link; copies made earlier remain with the people who made them.
9.4. Third-party content. When you capture vocabulary from pages and videos, you save short excerpts (a word, a sentence) for your own educational use. You are responsible for ensuring that the way you use other people’s materials — including sharing them in public sets — does not infringe their authors’ rights or the terms of the services they come from.
10. Acceptable use
10.1. You must not:
- provide unlawful content, including content that infringes others’ rights or incites hatred or violence;
- circumvent limits and safeguards, create accounts to multiply allowances, or call features in an automated way other than through the interfaces provided for that purpose;
- use AI features to generate content unrelated to language learning, or to try to extract system instructions;
- resell access to the Service or share your account with others;
- disrupt the Service, test its security without our consent, or decompile the apps — except to the extent permitted by law.
10.2. In the event of a serious or repeated breach we may restrict access to features or — after an unsuccessful request to stop — terminate the contract (section 13.2). You can report unlawful content to support@langpal.ai; we handle reports promptly and inform you of the decision and its reasons.
11. Third-party services
11.1. YouTube. Video features display the original YouTube page. By using them you accept the YouTube Terms of Service. We are not responsible for the availability or content of videos.
11.2. AI assistants. By connecting LangPal to an external AI assistant you authorise it to read and write your vocabulary. The assistant’s provider is responsible for the assistant’s actions and for data processing on its side. You can revoke access at any time.
11.3. The browser extension runs on the pages you visit locally, in your browser; the scope of data it sends is described in the Privacy Policy. We do not guarantee that the extension works on every page.
11.4. Signing in with Google or Apple is additionally subject to those providers’ terms.
12. Availability, liability and complaints
12.1. We make every effort to keep the Service running without interruption, but we do not guarantee that there will be none — AI features in particular depend on external providers. Where possible, we give advance notice of planned work that will materially limit access.
12.2. Towards Consumers we are liable for the conformity of the Service with the contract under consumer law (Chapter 5b of the Polish Consumer Rights Act, implementing Directive (EU) 2019/770). Nothing in these Terms excludes or limits the rights Consumers have under mandatory law.
12.3. Towards Users who are not Consumers, our liability — except for damage caused intentionally — is limited to the fees paid by the User in the 12 months preceding the event and does not cover lost profits.
12.4. To the extent permitted by law, we are not liable for the consequences of decisions made on the basis of AI-generated content (section 5), for content saved by Users, or for the operation of third-party services.
12.5. Complaints should be sent to support@langpal.ai, describing the problem and giving the email address of the account. We reply within 14 days. If the Service does not conform to the contract, a Consumer may demand that it be brought into conformity and, in the cases provided for by law, a price reduction or termination of the contract.
12.6. Out-of-court dispute resolution. A Consumer may seek help from a municipal or district consumer ombudsman, the permanent arbitration courts at the Trade Inspection, and mediation; information: uokik.gov.pl. Consumers resident elsewhere in the EU may contact the European Consumer Centre in their country. Use of these methods is voluntary for both parties.
13. Termination
13.1. You can terminate the contract at any time by deleting your account: in the app settings or at https://app.langpal.ai/delete-account. Deletion is irreversible; its effect on your data is described in the Privacy Policy.
13.2. We may terminate the contract on 14 days’ notice for good cause: a serious or repeated breach of these Terms despite a request to stop, or discontinuation of the Service. In the event of a flagrant breach of the law or a threat to the security of the Service we may block the account immediately, stating the reason. If we terminate because the Service is being discontinued, we refund the fee for the unused part of the period and provide a copy of your Content on request.
14. Changes to these Terms
14.1. We may change these Terms for good cause: a change in the law, a change to the features or model of the Service, a change of providers, security considerations, or the need to remove ambiguity.
14.2. We give notice of a change by email or in the Service at least 14 days before it takes effect. If you do not accept the changes, you may terminate the contract before that date by deleting your account; if a change materially worsens a paid Pro Plan, you are entitled to a refund for the unused part of the period. Changes do not affect rights acquired in a period already paid for.
15. Governing law and disputes
15.1. The contract is governed by Polish law. This choice does not deprive a Consumer of the protection afforded by the mandatory provisions of the law of the country of their habitual residence.
15.2. Disputes with Consumers are resolved by the court having jurisdiction under general rules. Disputes with Users who are not Consumers are resolved by the court having jurisdiction over the Provider’s registered office.
16. Additional terms for the app downloaded from the App Store
If you downloaded the app from the Apple App Store, the following also applies:
16.1. Acknowledgement. These Terms are concluded between you and the Provider only, and not with Apple. The Provider, not Apple, is solely responsible for the app and its content.
16.2. Scope of licence. We grant you a non-transferable licence to use the app on any Apple-branded products that you own or control, as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions.
16.3. Maintenance and support. Apple has no obligation whatsoever to furnish any maintenance or support services for the app.
16.4. Warranty. In the event of any failure of the app to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the app (if any); to the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the app.
16.5. Claims. The Provider, not Apple, is responsible for addressing any claims relating to the app — including product liability claims, claims that the app fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy or similar legislation — as well as any third-party claim that the app infringes that third party’s intellectual property rights.
16.6. Legal compliance. You represent that you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
16.7. Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of these Terms; upon your acceptance, Apple will have the right to enforce these Terms against you as a third-party beneficiary.
