About Streak
Streak is a habit tracker that respects you. Create as many habits as you like, log them with a single tap, and follow your progress through a GitHub-style activity grid, streak counters and a statistics dashboard. It is fast, offline, and built to feel calm rather than demanding. Yours, completely. No accounts, no subscriptions, no ads, no tracking. Every habit and setting stays on your device, and the full source is open.
Privacy and F-Droid
F-Droid builds Streak from its published source code and flags anti-features such as ads, tracking or reliance on non-free services.
No anti-features flagged on the latest F-Droid build.
