ReNotify

A notification history for Android. ReNotify keeps every notification you receive, including the ones you swiped away, and can put any of them back into your notification bar with its original time.

This is the open source edition. Every feature is free, there are no purchases, no banners and no advertising, and it sends nothing anywhere unless whoever built it chose a statistics server (see Statistics).

Download

Signed APKs are on the Releases page. The app id is com.renotify.oss, so it installs next to the Play Store edition instead of replacing it.

To check that an APK really comes from us, compare its signing certificate (apksigner verify --print-certs ReNotify-*.apk) with this SHA-256:

1C:BA:8A:C6:70:BE:0C:D3:64:AE:B8:87:33:6C:48:FE:36:85:E1:81:91:5A:09:26:1A:C5:C2:85:73:64:EC:A8

What it does

• History. App, title, full text and time of every incoming notification, grouped by app and searchable. Text can be selected, copied and shared.
• Resend. Push any saved notification back into the notification bar, one at a time, several at once, or all of them, with the original timestamp and the original app's icon.
• Remind me later. Turn a notification into a reminder: in an hour, this evening, tomorrow morning, or at a time you pick.
• Rules. Hide or silence notifications by app, keyword and time of day. Whatever a rule hides still lands in the history.
• Status bar filter. Let only the apps you choose stay in the status bar.
• Delivery per notification. Banner, sound, vibration and flashlight, decided per notification or per app.
• Your own notifications with any title, text, date and time.
• Widgets for the home screen: a list, a single row, or a counter for today.
• Trends: which apps interrupt you most, and when.
• Auto-delete after 1, 3, 7, 30 or 90 days, and CSV export.
• English, German, Spanish, French, Italian and Portuguese, with dark mode.

Limits worth knowing

• Recording starts when the app gets notification access. No app can read notifications from before that.
• Only text is stored, not images or attachments.
• A resent notification opens the exact chat or page it pointed to for about six hours and until the phone restarts. Android discards that link (the PendingIntent) after that; the notification then opens the app.
• Android starts a notification's sound before any app is told about it. A silence rule cuts the sound off and removes the banner, but a short tone can still get through.
• Calls, alarms, calendar reminders, navigation, media players and running services are never hidden or silenced, by any rule or filter.
• Whether every notification is captured also depends on the phone's battery management. The app shows how to exempt it.

Permissions

Permission	Why
Notification access	Reading and saving notifications. Granted in system settings, revocable at any time.
Post notifications	Putting saved notifications back and showing reminders.
Exact alarms	Reminders at the minute you picked.
Receive boot completed	Re-arming reminders after a restart.
Vibrate	Vibration for resent notifications, if you want it.
Ignore battery optimizations (request)	Asking to be exempted, so the history has no gaps.
Internet	Only for the statistics described below. A build without a statistics server never opens a connection.

Notification content stays in a local database on the device. Uninstalling the app deletes it.

Statistics

Statistics are off unless the build has a server for them. This repository ships without one: the TELEMETRY_URL placeholder is empty, the app never asks and never sends.

If you build the app for others and want to see which versions are in use, put your own server into secrets.properties:

TELEMETRY_URL=https://stats.example.com

The app then asks each user once and sends nothing until they agree. With consent it sends, about once a day, POST /api/ping with this JSON:

{
  "device": "random UUID created by the app",
  "version": "1.8.6",
  "versionCode": 20,
  "sdk": 36,
  "locale": "de-DE",
  "notifTotal": 1234
}

and after a crash POST /api/error with device, version, at (time in milliseconds) and stack (the stack trace, at most 4000 characters). Never notification content, titles or app names. Withdrawing consent deletes the random ID on the device.

The Play Store edition

ReNotify is also on Google Play. That edition is built from the same code by Fluxera LLC and differs in what it adds around the app:

• Pro is a one-time purchase through Google Play Billing; the free version keeps the last 7 days of history and has a 7 day Pro trial.
• The free version shows a small banner for our own apps. No ad network.
• The RevenueCat SDK runs in observer mode for revenue statistics. It contacts RevenueCat on every app start with a random identifier; it receives purchase confirmations, never notification data, names or email addresses.
• Statistics go to re-notify.com, only after the user agreed, as described above.

None of that is in this repository.

Building

You need JDK 17 or newer and the Android SDK (compile SDK 36).

./gradlew assembleDebug

The APK lands in app/build/outputs/apk/debug/. All keys in secrets.properties and keystore.properties are optional; see secrets.properties.template.
