Effective 2026-07-10 · applies to the ZMF Apps solo titles (Sudoku, and future solo apps that link here)
We collect nothing.
These apps have no accounts, no ads, no analytics, and make no network requests. Your puzzles, progress, streaks, and settings are stored only on your device and never leave it. There is nothing for us to sell, share, or lose, because we never receive anything in the first place.
If you delete an app, its data goes with it. If you email us for support, we see whatever you chose to write — that's the entire data flow.
