Privacy Policy

Effective Date: July 26, 2026  ·  Last Updated: October 5, 2026

Trei ("we", "us", "the developer") built App Uninstaller as an Android utility for reviewing installed apps and starting Android's built-in uninstall flow. This privacy policy explains what the app can access and how that information is handled.

The short version: App Uninstaller does not collect your name, email, contacts or account data, does not create accounts, does not show ads, and does not include analytics or crash-reporting SDKs. Once a day it sends a usage ping with the app name and your device's Android ID, so we can count how many devices use the app. Installed app information is processed on your device to show the app list and storage estimates. The app fetches a small public review prompt configuration and may send a masked non-fatal diagnostic event. Your app inventory is never sent.

Review Prompt Configuration

The app may request https://api.trei.dev/appuninstaller/config to read whether Android's native in-app review flow is enabled and its session timing. When eligible, the app may show a neutral review choice with Rate now, Not now, and Send feedback actions. It does not ask for sentiment or a rating score, and only Rate now opens Android's native review flow. This request does not send your installed app list, selected packages, uninstall history, account data, advertising identifiers, or a device identifier.

Review eligibility uses only local app state such as a session count, whether an uninstall was confirmed, dismissals, and recent local failure timing. That state remains in App Uninstaller's private Android storage.

Data Collection by the App

App Uninstaller does not sell or share your data. When a caught operation fails, the app may send a masked non-fatal diagnostic event to https://api.trei.dev/client-issues. If the app crashes, it sends the same masked event marked as a crash. It contains only a fixed operation context, exception class, generic failure message, Android platform, App Uninstaller package name, and app version. It does not include the raw error message, stack trace, installed app inventory, selected package, uninstall history, account data, advertising identifier, or device identifier. Google Play Data Safety purposes of App functionality and Analytics apply to these limited diagnostics because they are used to monitor reliability and measure technical failure patterns.

  • No user accounts, registration, or sign-in.
  • No advertising SDKs.
  • No analytics SDKs.
  • No crash-reporting SDKs.
  • No advertising identifiers. One device identifier, the Android ID, is sent with the daily usage ping described below.
  • No in-app server uploads of your installed app list. Selected packages are not uploaded.

Daily Usage Count

The first time you open App Uninstaller each day, it sends one request to https://api.trei.dev/hotApp/track containing the app name and your device's Android ID. The Android ID is a device identifier that Android creates for each app developer on each device. We use it only to count how many different devices use App Uninstaller per day, week and month. Google Play Data Safety lists this as Device or other IDs, collected for Analytics.

  • It is not used for advertising and is not sold or shared with third parties.
  • It is never combined with your installed app list, selected packages or uninstall history, which stay on your device.
  • It is sent over HTTPS and stored with the dates on which the app was opened.
  • To have the usage records for your device deleted, write to contact@trei.dev.

Installed App Information

The app reads the list of apps installed on your device so it can display app names, package names, icons, system-app status, and estimated app storage. This information is used only inside the app interface and remains on your device.

Uninstall Requests

When you select apps to remove, App Uninstaller starts Android's system uninstall confirmation flow. Android shows the final confirmation before an app is removed. App Uninstaller does not silently remove apps, does not require root access, and does not bypass Android restrictions for system or pre-installed apps.

Permissions

  • QUERY_ALL_PACKAGES - used to show installed apps in the app manager list.
  • REQUEST_DELETE_PACKAGES - used to request Android's system uninstall flow for apps you select.
  • INTERNET - used to fetch the public review prompt configuration, send masked non-fatal diagnostic events and send the daily usage ping. Installed app inventory is not uploaded. Selected packages are not uploaded.

A feedback shortcut may open the Trei feedback page in your browser; any information you choose to submit there is handled by the website feedback flow.

Children's Privacy

App Uninstaller is a general Android utility and is not directed at children under 13. We do not knowingly collect personal information from children.

Data Security

While the device is offline, up to 50 pending masked diagnostics may remain in App Uninstaller's private storage. Successful uploads are removed from this queue, and records older than seven days are purged the next time the app or background delivery worker accesses the queue. The diagnostic endpoint may retain the limited masked operational fields described above for reliability monitoring. It does not receive your name, email or account data, installed app inventory, selected packages, raw error messages, or stack traces. Local app information is protected by Android's app sandbox and removed according to Android's normal app data behavior.

Changes to This Policy

We may update this policy if App Uninstaller changes how it handles data or permissions. Any changes will be posted here with an updated "Last Updated" date.
