CallFortis Privacy Policy

Last updated: 3 November 2026

CallFortis ("the app", "we") is an Android call-blocking app developed by AndroCyborg. This policy explains what information the app uses and how it is handled. The short version: CallFortis does not collect your data, has no servers, and does not send your information to us or to anyone else.

1. Information we do not collect

We do not operate any backend. We do not collect, receive, store or sell personal information. The app has no user accounts, no advertising, and no analytics or crash-reporting services.

2. Information stored on your device

To work, the app keeps the following only in its private storage on your phone:

  • Phone numbers, patterns and rules you add to your block list, with optional reasons you type.
  • Your Trusted Numbers and quiet-hours schedules and exceptions.
  • A history of calls the app blocked or silenced (number, time, action taken, and the rule responsible).
  • Your settings and preferences.

This data is not transmitted by the app. Uninstalling the app deletes it, except for any backup files you chose to export (see section 5).

3. Permissions and why they are used

  • Call screening role (caller ID & spam app): lets Android pass incoming call numbers to the app so it can decide whether to reject or silence them. Each decision is made on the device.
  • Contacts (optional): used on the device to warn you before you block someone saved in your contacts, to let known contacts through, and to apply contacts-only and quiet-hours modes. Contacts are never uploaded or copied outside the app.
  • Call log (optional): used only to show your recent callers so you can pick one to block. It is not uploaded.
  • Notifications (optional): used to tell you when a call was blocked.
  • Ignore battery optimizations (optional): lets Android keep call screening running in the background so calls are checked the moment they ring.

You can decline or revoke optional permissions at any time in Android Settings. Some features will then be unavailable.

4. Purchases and reviews

The Premium upgrade is handled by Google Play Billing. Payment is processed by Google. We do not see or store your payment details. Google's handling of purchase data is governed by the Google Privacy Policy. The app may occasionally ask you for a rating using the Google Play In-App Review API, which is also operated by Google.

5. Backups and exports

App backups you control: the app can write automatic, versioned backups and let you export a backup file, optionally encrypted with a passphrase you choose. These files are saved to a location on your device that you select. If you store them in a cloud folder, they are subject to that provider's policies. If you lose your passphrase, we cannot recover an encrypted backup.

Android system backup: the app allows Android's built-in backup. If you have Google backup turned on for your device, Android may include the app's data in your backup on your own Google account, and restore it when you set up a new phone. This is performed by Android and Google, not by us, and is governed by Google's terms. You can turn it off in your device's Backup settings.

6. Sharing

We do not share, sell, rent or disclose your information to third parties. The app has no third-party advertising or analytics code.

7. Data retention and deletion

All data is under your control on your device. You can remove individual entries or clear your history inside the app. Uninstalling the app removes all of its stored data from your device. Because we hold no data on any server, there is nothing for us to delete on our side.

8. Children

CallFortis is not directed at children under 13 and does not knowingly collect information from anyone.

9. Security

Data is kept in the app's private storage, which other apps cannot access on a non-rooted device. Exported backups can be encrypted with your passphrase. No method of storage is perfectly secure, so we cannot guarantee absolute security.

10. Changes to this policy

If the app's data practices change, we will update this page and the "Last updated" date. Please check back from time to time.
