Privacy Policy

Last updated: May 28, 2026

This Privacy Policy describes how the Translate & Train mobile application (the "App", "we", "us") collects, uses, and discloses your information when you use the App.

By using the App, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

1.1 Account information

When you sign in to the App we receive one of the following from your identity provider:

Apple Sign In — your Apple user identifier and, if you choose to share it, your email address. If you select "Hide my email", Apple provides us with a private relay address (*@privaterelay.appleid.com) that forwards mail to your real inbox.
Google Sign In — your Google user identifier and the email address associated with your Google account.

We do not collect your name, profile picture, phone number, contacts, address, age, gender, or any other personal attribute from the identity provider.

1.2 Usage data

The App's backend records:

API request metadata — the model used (e.g. gemini-2.5-flash), approximate token count, timestamp, and the resulting cost estimate in USD. We use this to enforce your spending limit and to monitor service health.
Authentication tokens — short-lived bearer tokens issued on sign-in and stored in our database until rotation or sign-out.

We do not log the contents of your translations, dictionary entries, OCR images, or any prompts you send to AI models. Those contents are transmitted to the AI provider (see section 3) but are not retained by us beyond the duration of the request.

1.3 Locally-stored data

The following data lives on your device only and never leaves it:

Your dictionary words and phrases
Translation history
Practice progress and exercise statistics
Daily goal counters
Language pair preferences

You can wipe all local data at any time from Settings → Cleanup.

1.4 Device permissions

Camera (iOS + Android) — used only when you tap the OCR button to photograph text for recognition. Images are sent to the AI provider for OCR and discarded immediately afterward.
Photos (iOS) — used only when you select an image from your library for OCR.

We do not access the camera or photo library at any other time.

2. How We Use Your Information

We use the information described above to:

Authenticate you and persist your account across reinstalls
Enforce your lifetime API spending cap and process promo codes
Provide AI-powered translation, analysis, generation, and OCR
Monitor the health and cost of the service
Detect and prevent abuse

3. Third-Party Services

The App uses Google Gemini (a service of Google LLC) as its primary AI provider. When you use any AI feature (translate, analyze, generate, OCR), the text or image you submit is transmitted to Google Gemini through our backend in order to generate a response.

Google's handling of that data is governed by Google's privacy policy: https://policies.google.com/privacy

We have no control over what Google retains. You should not send secrets, personal credentials, or other sensitive data through the App.

In the future, we may add OpenAI and Anthropic as alternative AI providers, in which case their respective privacy policies will also apply when those providers are selected.

4. Data Storage and Retention

Account and usage data are stored on our server.
Authentication tokens are retained until you sign out or the token is rotated.
Account records and usage history are retained for as long as your account is active.

You may delete your account by emailing us (see section 9). On deletion, we remove your account record, redeemed promo history, and usage logs within 30 days.

5. Children's Privacy

The App is not directed to children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can delete it.

6. Security

We use HTTPS for all communication between the App and the backend. Tokens are stored in your device's secure storage. We do not transmit raw passwords because we do not use them — all authentication is delegated to Apple or Google.

No system is perfectly secure, however. You use the App at your own risk.

7. Your Rights

Depending on your jurisdiction (e.g. EU GDPR, California CCPA), you may have the right to:

Access the data we hold about you
Correct or delete that data
Withdraw consent to processing
Lodge a complaint with a supervisory authority

To exercise any of these rights, contact us using section 9.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be reflected in the "Last updated" date at the top of this page. Continued use of the App after a change constitutes acceptance of the updated policy.

9. Contact
