Apple has addressed a privacy bug that stored private Signal chats even after app deletion. The fix deletes preserved notifications and prevents future preservation, with Signal expressing satisfaction about the resolution. The vulnerability raised concerns about potential access to encrypted communications.

Users debate whether the update provides sufficient protection, with Signal president Meredith Whittaker suggesting disabling message previews for enhanced privacy. Some users worry about other potential vulnerabilities in iOS, while Apple clarified the issue was related to logging, not caching.

Governments increasingly use push notifications as an investigative strategy, and last year Apple provided authorities with notification data. Despite the fix, security experts recommend users take additional privacy measures to protect sensitive communications on their devices.
