Doza is built on a simple principle: your data belongs to you. We collect only what is strictly necessary to run the app and never use it for advertising or profiling.
What we collect
- A user ID and your app preferences (language, notification time, theme).
- Which cards you have read, your streak count, and your reading history.
- Your answer to each opinion question, counted anonymously in global percentages. It cannot be traced back to you.
- Device type and OS version, for debugging purposes only.
What we never collect
- Your name, email address, or any payment information.
- Location data or contacts.
- Behavioral profiles for advertising.
- Data sold to or shared with third parties.
How we use your data
To show your streak, reading history, and stats inside the app. To display global opinion percentages. To send a daily reminder notification if you opt in. To improve stability and fix bugs.
Storage and security
Your data is stored securely in Google Firebase (Firestore) on Google Cloud infrastructure. Firebase is GDPR-compliant and certified under ISO 27001.
Your rights
You may request access to, correction of, or deletion of your data at any time. Simply contact us and we will respond within 30 days.
