Stoke is a habit & streak tracker for Android. This policy explains what data the app handles and your choices. The short version: Stoke has no accounts, works offline, and your habits stay on your device. The only place your data can go is your own Google Drive - and only if you turn that on.
What the app stores on your device
Your habits, check-ins, notes, streaks and streak freezes, groups, reminders, settings, and a record of your trial/purchase status. All of it lives in a local database on your device. It is not sent to us - we have no server. You can export everything as a JSON file at any time (Settings → Your data), and uninstalling the app deletes the local data. One exception: a tiny record of your trial and purchase status is included in Android's standard device backup (stored with your own Google account, like other app settings) so that a reinstall can pick up where you left off. Your habits, check-ins and notes are not part of that backup.
Optional backup to a folder on your device
If you turn on automatic backup to a folder (off by default), the app saves backup files of your habit data - including notes and, for auto-tracked habits, the recorded values - and your app settings, such as the theme and quiet hours, to the folder you choose. The app writes those files only to that folder and sends them nowhere itself; where the folder lives is your choice. You can delete the files there at any time, and disabling the feature stops new backups.
Optional backup to your own Google Drive
If you turn on Drive backup (off by default), the app saves backup files of your
habit data - including notes and, for auto-tracked habits, the recorded values - and your app
settings, such as the theme and quiet hours, to your own Google Drive, in a
folder the app creates. The app uses Google's
drive.file scope, which limits its access to files it created itself; it cannot
see the rest of your Drive. The backup belongs to your Google account: we never
receive or can access it. You can delete individual backups from inside the app or
in Google Drive, and disabling the feature stops all future uploads. See
Google Drive's terms for how
Google handles your Drive storage.
Health Connect (optional auto-tracking)
You can connect a habit to Health Connect metrics (steps, exercise, sleep, distance, active calories). Access is read-only, asked per metric at the moment you connect it, and used on your device only to fill in that habit's check-ins automatically. Health data is never sent to us or to any third party by the app; the resulting check-in values are part of your local habit data and, if you enabled it, your own Drive backup. If you also allow background access, the app refreshes those check-ins about once an hour while it is closed, and again right before a reminder or streak insurance decides on a day, so an auto-tracked habit is up to date when you open it and you are not reminded about something you already did; declining keeps auto-tracking working whenever the app is open. You can revoke access at any time in the Health Connect settings.
Stoke's use of information received from Health Connect adheres to the Health Connect Permissions policy, including its Limited Use requirements: health data is used only to fill in your habits' check-ins, is never used for advertising, and is never sold or transferred to anyone.
Wear OS companion
If you install Stoke on a paired watch, your habit data syncs between your phone and watch through Google Play services' Data Layer: directly over Bluetooth when the two are connected, and otherwise through Google's servers, end-to-end encrypted. No cloud service of ours is involved.
NFC tags
If you link an NFC tag to a habit, the tag stores only a small reference that the app reads locally to log that habit. Nothing about you is written to the tag or transmitted anywhere.
Purchases (Google Play)
The one-time premium upgrade is processed by Google Play. Purchases are validated and restored on your device through Google Play Billing - the purchase belongs to your Google account, which is how it survives reinstalls and moves to a new device. We never receive your name, email, or payment details (those stay with Google Play). See the Google Play Terms of Service.
Usage analytics (Google Analytics for Firebase)
The app collects usage statistics through Google Analytics for Firebase: which screens and features are used, whether the app runs in the trial, free, or premium tier, and general device information (model, OS version, language, coarse country derived from IP). We use this to see which features matter and to improve the app. These statistics are aggregated and are not used to identify you. Your habit names, notes, and check-in contents are never sent. Purchase events carry no payment details - only that a purchase happened. The app does not use the advertising ID at all (the permission is removed from the app). Google may process these statistics on servers outside the EEA; such transfers are covered by Google's standard contractual clauses. See the Firebase Privacy documentation.
Crash diagnostics (Firebase Crashlytics)
The app collects anonymous crash reports (stack traces, device model, OS version) so we can fix bugs. See the Firebase Privacy documentation.
What we do NOT do
- No user accounts, registration, or login
- No ads, and no advertising ID
- No collection of names, emails, contacts, photos, or location
- No tracking of you across other apps or websites
- No data sold or shared with third parties beyond the processors above (Google)
- No cloud service of ours stores your habit data; the only cloud backup is to your own Google Drive, and only if you opt in
Deleting your data
Settings → Delete all data erases every habit and all its history from your device, and uninstalling the app deletes everything stored on it. Backups you made are yours: delete folder backups from the folder you chose, and Drive backups from inside the app (restore screen) or directly in Google Drive. Analytics and crash data held by Google is aggregated, not tied to an account, and expires per Firebase's retention policies.
Children
Stoke is a general-audience productivity app and is not directed at children under 13. We do not knowingly collect any data from children.
Your rights (GDPR)
If you are in the EEA, you have the right to access, correct, delete, or object to processing of your personal data. Because the developer holds no personal data about you - your habit data is on your device and in your own Drive - these rights are best exercised on-device (export, delete) or toward the processor above (Google). For anything else, contact us at the email above. You also have the right to lodge a complaint with your local data protection authority.
