Privacy Policy
Last updated: March 2026
What We Collect
When you sign in with Google or Apple, we store your name and email address. That's the only personal information we collect.
Everything else we store is learning data you create inside the app: saved vocabulary, quiz results, flashcard progress, article reading history, and daily usage counts.
What We Don't Do
- No cookies — we use stateless JWT authentication
- No Google Analytics, tracking pixels, or ad networks
- No IP address logging or device fingerprinting
- We never sell or share your data with advertisers
Third-Party Services
- OpenAI — powers word enrichment lookups. Results are cached so your queries aren't sent repeatedly.
- Stripe — handles payments. We never store your card details.
- Resend — sends transactional emails (e.g. weekly digests).
Local Storage
We save your theme preference and text-to-speech voice selection in your browser's localStorage. No cookies are set.
Data Retention
Your data is kept as long as your account exists. Database backups are retained for 7 days. If you'd like your account and all associated data deleted, email us at dogusural@gmail.com.
Your Rights
Under GDPR you can request access to, correction of, or deletion of your personal data at any time. Contact us at dogusural@gmail.com.
