About this app

NotiSync brings your notifications to every device you trust — your phone, your tablet, and more — without handing your private messages to anyone in the cloud.

Pick the apps you care about, pair your devices with a quick QR scan, and your notifications follow you. Everything is end-to-end encrypted, so titles, messages, senders, and images stay readable only on your own devices. There's no account to create and no profile to mine.

WHY NotiSync

• End-to-end encrypted — notification content is sealed on your device and can only be opened by your other trusted devices. The server is just a courier; it never sees your messages.
• No account, ever — no sign-up, no email, no password. Your devices trust each other directly.
• Pair with a QR code — one device shows a code, the other scans it. Keys are exchanged in person, not through a server.
• Choose exactly what mirrors — per-app control with a searchable list. Silent, ongoing, and media notifications are skipped automatically.
• Dismiss once, gone everywhere — swipe a mirrored notification away and it clears on your other devices too.
• Two-way by design — every device can both capture and show notifications, so your phone and tablet keep each other in the loop.
• Easy on your battery — built around Android's push system, with optional batching for low-priority alerts to cut noise and wake-ups.
• No ads, no trackers — NotiSync contains no advertising or analytics SDKs.

HOW IT WORKS

1. Install NotiSync on each device you want to keep in sync.
2. Pair them with a QR code — one device displays it, the other scans. Confirm the safety number and you're set.
3. Choose which apps mirror. From then on, their notifications appear on your other devices, end-to-end encrypted.

PRIVATE BY DESIGN

NotiSync is built so that the people running the service cannot read your notifications. Your encryption keys are generated on your device, stored in the Android Keystore, and never leave it. The relay server only forwards encrypted data and the minimum routing information needed to deliver it.
