RecallBox: Message History

RecallBox is a private, on-device history of new message notifications from apps you choose. Accept the storage disclosure, grant notification access and start protection to save supported notifications received from that point onward.

What you can do
• Save supported message notifications and browse conversation histories.
• Search saved notifications, filter by app and mark important records.
• Keep and view photo, video, audio and document attachments when a notification provides readable access.
• Choose a retention period, clean up older records and delete individual records.
• Lock the app using biometric or device authentication where supported.
• Export and import a password-protected text ZIP backup. Attachments are not included in backups.
• Stop saving new notifications and run a local notification connection diagnostic.

Understand the limits
RecallBox cannot recover deleted storage files or messages lost before installation and setup. Conversations that do not generate readable notifications, muted or open chats and hidden content may not be captured. Capture depends on the sending app and Android settings. It cannot restore the original text of OTP or other sensitive notifications hidden by Android.

Deletion phrases are recorded as notification signals only. They do not identify which original message was deleted. Attachments are saved only when the notification supplies a readable URI; expired access and size limits may prevent saving. This app does not scan storage for deleted files.

Permissions and device requirements
Requires Android 10 or later. Notification access reads supported notifications from selected apps. Notification posting permission is used for the local diagnostic notification. Battery optimization can affect background operation; you can review device settings when needed. Compatibility is not guaranteed for every messenger or device.

Privacy and languages
Saved notification records stay on your device; there is no cloud synchronization. Eligible new adult users may see a banner only in Settings after the required privacy choices. Google Mobile Ads may process device identifiers, IP-based approximate location, ad interactions and diagnostics for advertising, measurement and fraud prevention. Notification content is not sent to the ad SDK. You can turn ads off and revisit privacy choices in Settings. Existing ad-free installations remain ad-free. Exporting and sharing happen only when you choose them. App screens support Korean and English. Existing core features remain free and do not require watching ads.
