All the APK files you can download here are genuine (ie. not repacked, modified or tampered with) and digitally signed by each application's developer.
This also means that, once you install an APK from Appstia, you will receive updates via the Google Play Store normally, just like applications you install from there.
All APK downloads are hosted by Appstia and the files are checked before being posted. The digital signatures must match with other applications or releases from the same developer.
Additionally, multiple antivirus solutions are also used to scan the files and you can consult the most recent scan log. Note that in some rare cases there might be a few warnings (also known as false positives), but they are still safe to use.
How do we make sure the updated Apps are real and created by the respective developers?
1. All Appstia.com apps are verified prior to publishing.
2. We make sure that the cryptographic signatures for new versions of all previously published apps match the original ones, which means we know if the new version APKs were signed by the real developers or someone pretending to be them.
3. For new apps that have never been published on Appstia.com, we try to match the signatures to other existing apps by the same developer. If there’s a match, it means that the same key was used to sign a previously known legitimate app, therefore validating the new upload. If we’re unable to verify the legitimacy of a new APK, we will simply not publish it on Appstia.com.
Appstia does not repack software for distribution. It provides direct downloads of software in its original provided form, links to developers's downloads, or both. Appstia hosts some products on its own servers in case they are unavailable from their developers' sites.
