Delete your Delta Hub data

1. Summary

Delta Hub uses no accounts or sign-in, so there is no "account" to delete. This page explains what data exists and how to delete it, in compliance with Google Play requirements.

2. Data stored only on your device

The following is stored locally on your phone and never uploaded to a server:

• Saved articles.
• Preferences (language, theme, notification toggles).
• The Delta tab key history.

3. How to delete your local data

You can delete it at any time:

• From the app: Settings → "Clear Delta history" for the key history.
• By uninstalling Delta Hub: all of the app's local storage is removed.
• From Android: System Settings → Apps → Delta Hub → Storage → Clear data.

4. Server data: notifications token

The only data tied to your device that may exist outside it is the notifications token (FCM), which is anonymous and used only to send you alerts. It is invalidated when you uninstall the app or turn off notifications.

5. How to request token deletion

If you want us to proactively delete the token tied to your device, write to mkdevs@mkdevsapp.com with the subject "Delete data Delta Hub" and include:

• A short description of your request.
• If possible, the FCM token (you can see it in Settings → notifications token).

6. Data we retain

We may retain, anonymized and for a limited time, usage and crash metrics (Firebase Analytics) with no personal identifiers, to improve the app. They don't include personal data of yours.

7. Processing time

Local deletions are immediate. Email requests are processed within a maximum of 30 calendar days; you'll receive an email confirmation.
