Privacy Policy

Privacy Policy for Learn Polish
Effective date: March 27, 2026

Learn Polish ("App", "we", "us", "our") is a language learning app for studying Polish vocabulary with flashcards, manually created dictionaries, imported JSON dictionaries, optional AI-generated dictionaries, and, in the native iOS and Android versions only, optional subscription-based premium features.

This Privacy Policy explains what data is processed when you use the App, where it is stored, and what choices you have.

1. Who is responsible for processing personal data

The controller of personal data processed through the App is:

Maksym Kyselov
Email: m.kiselyow@gmail.com
Address: Warszawa, ul. Borsucza 55/11, 02-213, Poland

2. What data is stored locally on your device

Most App learning data is stored locally on your device or browser storage and is not sent to us simply because you use the learning features.

The App may use text-to-speech functionality available on your device to pronounce Polish words. This functionality depends on your device, operating system, installed voices, and language support.

This local data may include:

• dictionaries,
• words, translations, examples, and declensions,
• learning progress and review history,
• selected dictionaries,
• interface language,
• app settings.

You can export this data yourself and import it on another device.

Subscription functionality does not apply to the web or PWA version of the App.

3. What data is sent when you use AI dictionary generation or native subscription features

If you use the AI dictionary generation feature, the following data may be sent to our server and to our AI service provider for the purpose of generating a dictionary for you:

• topic,
• quantity,
• additional notes,
• selected native language,
• limited technical request data necessary to provide and protect the feature.

If you use subscription features in the native iOS or Android version of the App, subscription-related data may also be processed by Apple App Store or Google Play, and by our subscription infrastructure provider RevenueCat, as needed to validate purchases, determine entitlement status, support restore purchases, and manage subscription access inside the native app.

This subscription-related data may include:

• an anonymous or pseudonymous app user identifier,
• purchase, entitlement, subscription, and renewal status information,
• trial or introductory offer eligibility or status where available from the store,
• limited technical, device, app, or store-related information needed to validate and manage subscriptions.

We do not state that your name or email address is sent to RevenueCat unless you separately provide such data through another channel.

4. IP address and security-related processing

When you use the AI dictionary generation feature, we may temporarily process your IP address and limited technical request metadata in order to:

• prevent abuse,
• apply request limits,
• protect the service from excessive or automated traffic,
• control the operating costs of the AI feature.

We do not use this information for advertising or user profiling.

5. Why we process data

We process data only as needed to operate the App and provide the AI generation feature.

We may process data for the following purposes:

• to provide the AI dictionary generation feature you request,
• to enable and manage subscriptions in the native iOS and Android versions of the App,
• to validate purchases and restore purchases,
• to determine whether premium subscription access is active, expired, canceled, in trial, or otherwise available through the relevant store,
• to protect the App and prevent abuse,
• to enforce technical limits on AI usage,
• to respond if you contact us for support,
• to comply with legal obligations where required.

6. Legal bases

Where applicable under data protection law, we rely on the following legal bases:

• performance of a requested service — when you ask us to generate an AI dictionary,
• legitimate interests — for security, abuse prevention, rate limiting, and cost control,
• legal obligation — where processing is required by law.

7. AI notice

The AI generation feature creates content automatically.

AI-generated content:

• may contain inaccuracies or mistakes,
• may be incomplete,
• may resemble existing materials,
• should be reviewed by you before use.

Please do not enter personal data, sensitive data, passwords, or confidential information into AI prompts.

8. Service providers

We may use third-party service providers strictly as needed to operate the App, including:

• hosting and infrastructure providers such as Vercel,
• AI service providers such as OpenAI used to generate dictionaries,
• subscription infrastructure providers such as RevenueCat for native iOS and Android subscription management only.

These providers may process the data necessary to perform their services.

In the native iOS and Android versions, purchases are processed by Apple App Store or Google Play, not directly by us.

9. International transfers

Some service providers may process data outside your country. Where required, such transfers are made subject to applicable legal safeguards.

10. Data retention

10.1 Local learning data

Your learning data stays on your device until you delete it, reset the App, clear storage, or uninstall the App.

10.2 AI request and security data

We try to minimize retention.

For the current implementation:

• short anti-abuse request counters may be kept temporarily for approximately 1 minute,
• weekly request-limit records may be kept temporarily for approximately 7 days.

10.3 Subscription-related data

In the native iOS and Android versions, limited subscription-related records may be processed and retained by Apple App Store, Google Play, and RevenueCat in accordance with their own systems and retention practices, and by us only to the extent needed to operate subscription functionality, restore purchases, respond to support requests, or comply with legal obligations.

Most learning data remains local on your device and is separate from subscription status data.

If you contact us by email, we may process the contact details and message you provide in order to respond to you.

11. Your rights

Where applicable under data protection law, you may have the right to:

• request access to personal data we process about you,
• request correction of inaccurate personal data,
• request deletion of personal data,
• request restriction of processing,
• object to certain processing,
• request data portability,
• lodge a complaint with a competent supervisory authority.

These rights are not absolute and depend on the circumstances and applicable law.

Because most App data is stored locally on your device, you can directly access, export, and delete much of your data yourself inside the App or by clearing device or browser storage.

Because subscription purchases in the native iOS and Android versions are processed through Apple App Store or Google Play, some billing, purchase, cancellation, refund, and store-account related data may be controlled by those platforms and not directly by us. Deletion of local App data does not by itself cancel a subscription or erase store-side purchase records.

To contact us about rights requests, use: m.kiselyow@gmail.com

12. How to delete your data

Because most App data is stored locally on your device, you can delete it by:

• using the App's Reset App / Delete Local Data function,
• clearing browser or app storage,
• uninstalling the App.

This removes local dictionaries, progress, and settings from your device.

If you have an active subscription in the native iOS or Android version, deleting local App data or uninstalling the App does not automatically cancel your subscription. Subscription management and cancellation must be handled through your Apple or Google account settings.

13. Children

The App is not specifically directed to children. If use by a child requires parental or guardian consent under applicable law, such consent must be obtained by the user or their parent or guardian.

14. Native subscriptions

The native iOS and Android versions of the App may offer one monthly auto-renewing subscription. A 7-day free trial or other introductory offer may be available where supported by the relevant store configuration.

Subscription pricing, trial availability, introductory offers, billing terms, and feature availability may vary by platform, store, country, or region.

Subscriptions automatically renew unless canceled by the user through their Apple App Store or Google Play account settings.

The App may provide a restore purchases function in the native version to help recover subscription access associated with the relevant store account or supported subscription record.

15. Changes to this Privacy Policy

We may update this Privacy Policy from time to time. The latest version will be made available in the App or on the website, and the effective date will be updated.
