Cryptogram — privacy

Drozd Studios · updated 2026-09-07

This app collects nothing about you.

There is no account, no sign-up and no profile.

The app sends nothing anywhere. It works with the network switched off, and it does not contact us or anyone else while you use it.

The one thing it writes down is your progress — the letters you have placed and which puzzles you have solved — under the name sifrovko.progress.v1 in your browser's local storage on the device. Removing the app removes it.

Your progress is kept on your device, and Android's own backup may include it if you have that switched on.

There is no advertising and no advertising identifier.

There is nothing to buy: no purchases, no subscription, no unlockable content.

Android permissions requested: android.permission.INTERNET. INTERNET is required by the app framework to load the app's own files from the device; the app makes no requests of its own.

The app never asks for the microphone, the camera or your location.
