WakeNudgePrivacy Policy
Last updated: 21 October 2026
WakeNudge: Alarm Clock ("WakeNudge", "the app") is a free, open-source alarm clock. This policy explains what the app does with information. Short version: everything stays on your phone.
- Developer: riyadmondol2006, source code at https://github.com/riyadmondol2006/WakeNudge
- Privacy contact: open an issue at https://github.com/riyadmondol2006/WakeNudge/issues
- This policy: https://github.com/riyadmondol2006/WakeNudge/blob/main/PRIVACY.md
The short version
- Network: the app's only network feature is a once-a-day check for a newer release. See "Update check in the GitHub version" below. You can switch it off.
- There are no accounts, no ads, no analytics, no crash reporting, no advertising ID and no tracking of any kind.
- No third-party SDK that collects data is included. The only libraries are open-source Android and Kotlin libraries for the user interface, storage, camera and barcode decoding, all running on the device.
- We (the developer) receive no data from the app, so we hold nothing about you.
What is stored, and where
Everything below is stored only on your phone, in the app's private storage, which other apps cannot read. It is created by you using the app and is used only to make the app work:
| Data | Why |
|---|---|
| Your alarms (times, labels, repeat days, sounds, missions), groups, timers, world clocks, exception dates and settings | So your alarms work |
| References to sound files you picked (the file's address, not a copy) | So the alarm can play your own music |
| Alarm history (when each alarm rang, snoozed, was dismissed or missed, how many missions were done) | The morning dashboard and streaks |
| A short diagnostics log (scheduling events, errors) | The Alarm health screen. It is bounded and never leaves the phone unless you export and share it |
| For the QR/barcode mission: the text of the code you chose | To check that you scanned the same code |
| For the NFC mission: the identifier of the tag you chose | To check that you tapped the same tag |
| For the photo mission: a compact fingerprint of the scene (a 32×32 grayscale layout and a colour histogram, a few hundred bytes) and a tiny reference thumbnail (about 80 pixels on its longest side, a few kilobytes) | The fingerprint checks that the camera is looking at the same place. The thumbnail shows you in the alarm editor what to photograph. The full-resolution photo is never saved, and the fingerprint cannot be turned back into a recognisable picture |
Alarm data is kept in device-protected storage so alarms can ring after a restart before you unlock your phone.
None of this is collected, transmitted or shared by the app. Step counts, squat counts and other sensor readings used during missions are used live and are not stored.
Permissions and sensors
Each permission is requested only when the feature that needs it is used. See the permission list for every one and why. In short: the camera is used only while a QR or photo mission is on screen, frames are processed in memory and are never saved or sent; activity recognition / step counter and the accelerometer are used only during the steps, shake and squats missions; calendar access is optional and read-only, used only to find which days are all-day events (for example public holidays) in the calendars you pick, and the app reads neither event titles nor descriptions; NFC is used only for the NFC mission. The app never asks for your location, contacts, microphone, phone, SMS or files.
Update check in the GitHub version
This section applies to the APK from GitHub Releases, the version this website offers.
- The GitHub version holds Android's
INTERNETpermission for one purpose: askingapi.github.comwhether a newer release of WakeNudge exists. It is on by default and can be switched off in About, under Updates. - It runs at most once a day. The request carries no account, alarm data, settings, device identifier or advertising ID. Like any web request it necessarily exposes your IP address and standard request headers (such as the user-agent) to GitHub, which handles them under its own privacy statement. We cannot see those requests.
- If a newer release exists the app only offers to open the release page in your browser. It does not download or install anything by itself.
Backups and exports
A backup is a JSON file that you create and you choose where to save, through Android's file picker. WakeNudge does not upload it and keeps no copy. It contains your alarms (including labels and, for missions, the QR text, NFC tag identifier, photo fingerprint and thumbnail), groups, world clocks, exception dates and settings, and optionally your history. Anyone who can read that file can read those things, so store it accordingly. The same applies to the Alarm health diagnostics export if you choose to share it; that report contains counts, reliability-related settings and engine events, and no alarm names or labels.
The app opts out of Google's cloud backup and of automatic phone-to-phone transfer, so no copy of your data is made behind your back. To move to a new phone, use the backup file.
How long data is kept, and deleting it
Data stays on your phone until you delete it. You can delete individual alarms, timers, history and other items in the app. Uninstalling the app or clearing its storage in Android settings removes everything it stored. Backup files you saved elsewhere are yours to delete. Because the developer never receives your data, there is nothing to delete on a server and no account to close.
Security
Data is kept in the app's private storage and is not readable by other apps. The only network feature is the optional update check described above. The app's code is open source, so anyone can check these statements.
Children
WakeNudge is not directed at children under 13. The app collects no personal information from anyone, including children.
Changes
If this policy changes, the new text will be published at the address above, the "last updated" date will change, and the change will be visible in the repository history and the release notes.

This website
This website is a set of static pages. It sets no cookies, runs no analytics, advertising or tracking scripts, loads no third-party fonts, scripts or images, and has no forms or accounts.
Like any web host, the hosting provider (Vercel) may keep standard server logs, for example your IP address, the time of the request and the page you asked for. The site itself does not read or use them, and the author adds no tracking on top. See Vercel's privacy policy for how it handles them.
Links to GitHub leave this site. GitHub handles what happens there under its own privacy statement.
