Download Guide

Read what the app is presented as first. If a check fails, see the APK questions or the legal limits.

These checks are informational, not a download endorsement. Android labels vary by device; read every security prompt before continuing.

1. 1

   Verify the publisher

   Match the publisher name, official domain, support contact, privacy policy, and release history. Similar names and logos are not proof of ownership.

2. 2

   Match the file

   Compare the exact version, file size, signing identity, and SHA-256 hash with a first-party release record before opening the APK.

3. 3

   Run Android checks

   Keep Google Play Protect enabled, scan the file, and reject permissions unrelated to the app's stated function.

4. 4

   Confirm legal suitability

   Do not proceed if the app requires money or stakes for a financial return. Check current national and local rules and obtain legal advice when uncertain.
