DOStreak is a habit tracker for iOS. This page explains what data the app handles, why, and your choices. It is written to be short and honest.
DOStreak is developed by Dominic Kennedy (dmnc.tech). Questions or requests: dmnc@dmnc.tech.
We do not collect analytics, advertising identifiers, location, contacts, or any tracking data. There are no third-party ad or analytics SDKs.
Your email is used solely to authenticate your account. Your habit data is used solely to provide the app: to show your habits and streaks and to sync them across your devices. We do not sell your data and do not share it for advertising.
Account and habit data are stored using Google Firebase (Firebase Authentication and Cloud Firestore), acting as our data processor. Access is restricted by owner-only security rules, so only your account can read or write your habits. If you sign in with Google or Apple, that provider authenticates you; we receive only your email/identifier, not your password. See Google’s privacy practices at firebase.google.com/support/privacy.
Your data is kept while your account exists. You can delete any habit in the app at any time, and Settings → Delete Account removes your account and all associated data. You can also email dmnc@dmnc.tech from your account address and we will remove it.
DOStreak is not directed to children under 13 and we do not knowingly collect data from them.
We may update this policy; material changes will be reflected by the date above.
