Privacy Policy
Dechen Study is a study app for Buddhist texts, guided reading, quizzes, and optional account features. This page explains what data the app may collect, how it is used, and how to request help or deletion.
Information We Collect
- Email address and authentication data if you create an account or sign in using Supabase authentication.
- Your name and email address, if you sign in with Apple (in the iOS and macOS apps) or Google (in the Android app). Apple and Google share these with Dechen Study at sign-in and nothing else. With Apple you can choose Hide My Email, and we then receive only a private relay address that forwards to you.
- App usage events, such as screens opened, reading or quiz activity, and notification interactions, when analytics is enabled for the configured environment.
- A coarse country code derived from your network request to help us understand regional usage.
- On-device preferences such as selected texts, reminder choices, and notification timing.
How We Use Information
- To create and secure your account.
- To provide study features, optional reminders, and account recovery.
- To understand app usage and improve the product.
- To operate app administration features such as announcement targeting for signed-in users.
Third-Party Services
Dechen Study uses Supabase for authentication and backend data services. If you sign in with Apple or Google, that company confirms who you are to Supabase under its own privacy terms. When analytics is on, it also asks country.is for a coarse country code for usage analytics; that service states that it keeps no request logs. The most recent country code is remembered on your device. These providers process data according to their own privacy terms.
Notifications
If you enable daily reminders, notification preferences are stored on your device and local notifications are scheduled there. You can turn reminders off at any time in the app’s Settings screen.
Data Sharing
We do not sell your personal information. We share data only with service providers needed to run the app, such as Supabase and the limited analytics services described above.
Retention and Deletion
On-device preferences remain on your device until you remove the app or clear them through app settings. Detailed usage events are retained for four weeks. A de-identified first-launch tally is retained longer so the app can measure installs over time. Account records may be retained until they are no longer needed to operate the service or until you request deletion, subject to legal or security needs.
Your Choices
- You can use most reading features without signing in.
- You can stop new usage analytics at any time in Settings → Privacy.
- You can disable daily notifications in Settings.
- You can delete your account in the app’s Settings screen when signed in.
- You can also contact us for privacy or deletion requests.
