Privacy Policy
CHUO KAIKEI K.K. ("we") explains below how the Android app "Notification Purge" (the "App") and its website handle your information. The Japanese version of this policy is the governing version; this English version is provided for convenience.
1. Information the App handles only on your device
The App handles the following information only on your device. It is never sent to our servers or to third parties, and we cannot access it.
| Information | Purpose |
|---|---|
| Notification content (the app that posted it, the notification title, the notification type, etc.) | If you grant "Notification access", to clear notifications from the shade while muted. The time, app name and title of cleared notifications are kept as a history on your device (up to 100 entries). |
| App settings (timer, schedule, mute options, etc.) | To provide the App's features. |
| Do Not Disturb state | To restore your previous setting when muting ends. |
2. Information collected by third parties for ads and usage analytics
Advertising (Google AdMob)
The App uses Google AdMob, provided by Google LLC. To serve and measure ads and to prevent fraud, AdMob may automatically collect:
- Device identifiers such as the Android advertising ID
- IP address and approximate location derived from it
- Device and app information (model, OS version, language, etc.)
- Ad interactions (views, taps) and diagnostic information such as crashes
In the European Economic Area, the UK and Switzerland, the App asks for your consent on first launch and serves ads according to your choice. You can change it at any time under "About this app" → "Change ad consent settings" (shown only in those regions). To limit personalized ads, reset or delete your advertising ID in your device's Settings → Privacy → Ads.
Usage analytics and crash reports (Firebase)
To improve the App and fix bugs, the App uses Firebase Analytics and Firebase Crashlytics, provided by Google LLC. The following is sent to Google:
| Information | Purpose |
|---|---|
| Which features are used and how often (e.g., turning the one-tap button on/off, starting a timer and its length, turning the schedule on/off), app launches and usage time | To understand which features are used and improve the App |
| Crash records and diagnostics such as device model and OS version | To find and fix bugs |
| Identifiers such as the app instance ID, approximate region derived from the IP address | To count users |
Notification content (the app that posted it, the title, etc.) is never sent. This information is not used for advertising. In the EEA, the UK and Switzerland, measurement is done without storing identifiers. You can stop sending it at any time by turning off "Send usage and crash data" under "About this app".
See Google's Privacy Policy, How Google uses information from sites or apps that use its services, and Firebase privacy and security.
3. Launch notification sign-up on the website
| Information | Email address and sign-up time |
|---|---|
| Purpose | To send you a single email when the App launches on Google Play. It is not used for anything else, such as marketing emails. |
| Storage | A Google Form / Google Sheet managed by us (a Google LLC service) |
| Retention | Deleted within 30 days after the launch email is sent |
| Withdrawal | Email support@notification.sucks and we will delete it promptly. The launch email will also explain how to opt out. |
4. Website analytics (external transmission)
The website (https://notification.sucks) uses the following services to understand how it is used. They send information from your browser to these companies:
| Recipient | Information sent | Purpose |
|---|---|---|
| Google LLC (Google Analytics) | Pages viewed, referrer, time, browser and device type, approximate region from IP address, cookies and other identifiers, on-page actions (button clicks, completing the sign-up) | Analyzing traffic and improving the site |
| Cloudflare, Inc. (Cloudflare Web Analytics) | Pages viewed, referrer, browser and device type, approximate region (no cookies) | Analyzing traffic |
For visitors from the EEA, the UK and Switzerland, Google Analytics runs without cookies. To opt out of Google Analytics, use the Google Analytics Opt-out Browser Add-on. For analytics inside the App, see section 2.
5. Permissions used by the App
| Permission | Purpose |
|---|---|
| Do Not Disturb (modes) access | To silence sound, vibration and pop-ups, and restore them afterwards |
| Notification access (optional) | To clear notifications from the shade. The App explains this and asks for your consent before you grant it. |
| Alarms & reminders | To start and end muting exactly on time |
| Run at startup | To restore schedules after the device restarts |
| Internet and advertising ID | To show ads (Google AdMob) and to send usage analytics and crash reports (Firebase) |
6. Sharing with third parties
Except as described in section 2 (ads and usage analytics) and section 4 (website analytics), we do not provide your information to third parties. We do not collect or store your information through the App (except the launch sign-up in section 3).
7. Deleting your data
The App has no user accounts. You can delete the data on your device at any time by:
- "About this app" → "Delete all app data" in the App, or
- Uninstalling the App
See Deleting your data for details, including ad and analytics data.
8. Children's privacy
The App is not directed to children under 13.
9. Security
Information the App stores on your device is kept in the App's private storage on Android and cannot be read by other apps.
10. Changes to this policy
We may update this policy to reflect changes in law or new features. We will announce important changes on this page and in the App.
