NotiSync brings notifications from your other devices to your iPhone, while keeping notification content encrypted in transit. Pair your iPhone with NotiSync on your other devices, choose what should be mirrored, and receive native iOS alerts for messages, email, events, reminders, and app notifications. Mirrored notifications are decrypted on device and can include sender avatars, conversation-style messages, and attachments when the source device provides them. Features: - End-to-end encrypted notification mirroring across trusted devices - QR code and pairing-link setup with verified device identities - Safety numbers and key fingerprints for trust checks - Native iOS notification rendering through APNs, foreground delivery, relay fetch, and background refresh paths - Synced dismissals, so clearing a mirrored notification can clear it across your trusted devices - Per-device, per-app, and notification channel controls to silence what you do not want on your iPhone - Inbox, trusted device list, activity log, delivery diagnostics, and route status - Private asset handling for icons, avatars, and attachments without exposing notification content to the relay - Signed trust updates and key rotation for long-running device meshes NotiSync is built for people who use more than one phone or device and want important alerts nearby without forwarding readable notification content through a server. The relay coordinates delivery, but it only handles encrypted envelopes and routing metadata. Requires NotiSync on at least one paired device and notification permission on this iPhone. Some features depend on the source platform, device permissions, relay availability, and OS support.
