1. Signature fingerprint (the real guarantee)

All our APKs are signed with the same key. Android requires that signature on install and rejects any update with a different signature: that's why a tampered app CANNOT be installed over yours. This is the fingerprint (SHA-256) of our signing certificate; it's the same across all versions:

7379394507e8311c3a1d73bfc0e737c46032bc97e829eee9fa179dab63bf0246 Copy

Check it with: apksigner verify --print-certs looklock.chat.v0.08.apk (it will give a "certificate SHA-256 digest": it must match the one above).

2. File SHA-256

Additionally, this is the SHA-256 hash of each build. It confirms the downloaded file is identical to what we published, without a single changed byte.

looklockchat-v3.0.195.apk (latest):

7fe3dd920b8ac25d619245c7a58c61358d65ca8b8db085ff913191027ce0029a Copy

How to check it

• Windows: certutil -hashfile looklock.chat.v0.08.apk SHA256
• Linux / Mac: sha256sum looklock.chat.v0.08.apk
• Android: a hashing app (e.g. "Hash Droid") on the downloaded APK.

The value you get must match, character by character, the one on this page.

Honest note: this hash is published on our server. If someone fully compromised the server, they could change the APK and its hash at the same time. That's why the strongest guarantee is the SIGNATURE (our key is offline): that fingerprint can't be forged by anyone without the key, and Android always checks it.
