Your habits. Your device. Period.
Streaky has no backend, no account system, no cloud sync, no analytics. Every habit, check-in, streak, and achievement lives only on your phone. The only third party involved is Google AdMob, which serves non-personalized ads so the app can stay free, and no behavioral profile of you is ever built.
