Notification History & Saver

Notification history and notification saver: once you turn on notification access, notifications from the apps you keep included are saved so you can search past alerts, see when one was dismissed and compare updates to it. Notice Keeper also shows whether capture is listening and makes a history backup.

▶ CHECK THAT CAPTURE SAVED THE TEST
• The status card shows Listening, access problems, a disconnected listener or a database write failure, together with the last saved time when available.
• Open Health and tap Send test. A pass means the diagnostic notification was saved in the database, rather than confirming that a notification was displayed.
• The test reports permission denial, a blocked test channel, a disconnected listener, a write failure or a timeout.
• Open notification access, app settings or battery settings from Health. Read guidance for background activity when capture is interrupted.

▶ COMPARE CAPTURED UPDATES
• Open a notification to see Updates to this notification, with saved versions in order.
• Before and After show changes to the title, text, expanded text and subtext between captured versions.
• When a matching removal event is received, see its time and whether the notification was dismissed by the user, cancelled by the app, cleared with all notifications or removed for another reason.
• These are changes to posted notifications, rather than a record of edits inside a conversation.

▶ FIND PAST NOTIFICATIONS
• Browse the Timeline grouped by hour, search captured text and filter by app. Search also checks earlier captured versions.
• Partial-word search handles Unicode text, with substring matching for Chinese, Japanese and Korean text.
• Load older notifications without automatic updates replacing the pages you have opened. Use Refresh history when changes are waiting.
• In Apps, see notification counts and choose which apps to exclude from future capture. Existing history stays until you delete it or your retention period ends.

▶ KEEP AND EXPORT YOUR HISTORY
• Choose Keep history for 7, 30, 90 or 365 days, or Until I delete it. See the history size in Health.
• Export readable JSON or CSV, or create a SQLite history backup with captured updates, removals, preferences and deletion records.
• Restore a history backup by merging records and deletions. Its retention and exclusion settings are applied; previously deleted records remain excluded.
• Confirm deletion of a notification or all history, with Undo available briefly afterwards.

▶ GOOD TO KNOW
• Capture starts after notification access is enabled. Earlier notifications cannot be recovered, and sensitive text may be hidden by the system.
• A passed test confirms that test write. Battery restrictions and listener interruptions can still cause future notifications to be missed. Retention cleanup runs periodically and may be delayed.
• The app’s own notifications, system interface notifications and ongoing media notifications are excluded by default. The diagnostic test is stored separately.
• History is stored in the app database. Exports are created in the app; copies you share or save elsewhere remain where you put them. Exported files contain sensitive notification text. JSON and CSV are readable exports; restore uses a SQLite backup.
• Hide screen content blocks screenshots and hides app switcher previews; it is not an app lock.
