Delete your data or CalkTalk account

App: CalkTalk · Developer: Rudnowski

You can delete some or all of your data with or without deleting your messenger account. Below are step-by-step instructions for each option.

Delete data without deleting your account

In the app (immediate, on your device):

1. Open the messenger (enter your PIN on the calculator and hold "=").
2. Delete a chat: open the contact list, remove a contact — the chat and messages with that person are deleted from your device.
3. Delete individual messages: remove selected messages in a chat (stored only on your device).
4. Block a user: Settings → Blocked users — stops further interaction; you can unblock later.
5. Remove a linked device: Settings → Devices — delete a device registration from your account.
6. Delete a local backup: remove the backup file from Google Drive or iCloud in your cloud app.

Server-side data (without closing your account): email support@rudnowski.dev with subject CalkTalk data deletion, your Public ID, and what you want removed (e.g. avatar, FCM token, pending messages). We process requests within 30 days.

Delete your account (all server-side data)

In the app (recommended):

1. Open the messenger (enter your PIN on the calculator and hold "=").
2. Go to Settings → Delete account and all data.
3. Enter your messenger password and confirm.
4. Your account is deleted on the server immediately; chats, contacts, PIN, and keys are removed from this device.

Or by email: send a message to support@rudnowski.dev with subject CalkTalk account deletion and your Public ID. We process requests within 30 days.

Data deleted from our servers

• Account identifier (Public ID) and authentication record
• Public encryption keys registered for your account
• FCM push notification token linked to your account
• Pending encrypted message payloads addressed to your account (if any)
• Avatar and profile metadata stored on the server (if set)

Data stored only on your device (not on our servers)

Message history, contacts, local settings, PIN, and panic PIN are stored encrypted on your phone. We do not keep a copy on our servers. Uninstalling the app removes this local data from your device.

Data that may be retained temporarily

• Server logs (IP address, technical errors) — up to 90 days, then automatically deleted.
• Email correspondence about your deletion request — retained as long as needed to process the request and comply with legal obligations, then deleted.

Backups you created yourself

If you saved an encrypted backup to Google Drive or iCloud, that file remains in your cloud account until you delete it there. We cannot delete third-party cloud files on your behalf.
