Privacy Policy

Effective Date: September 4, 2026
Developer: Niek.li (info@niek.li)
Application: Niek.li Chores (li.niek.chores)

Summary

Niek.li Chores stores everything on your device. It collects no analytics, contains no advertising, and has no trackers.

From version 7.2 the app can optionally sync a household between devices. That sync is off by default and does nothing until you turn it on and sign in. With it off, nothing leaves your device. This policy describes both states.

1. With sync off (the default)

• Nothing is transmitted. No analytics, no crash reporting, no advertising identifiers, no account.
• Local data: Homes, rooms, chores, subtasks, recurrence settings, effort estimates and completion history are stored on the device in a sandboxed database, private to the app.
• Household members: Names you add are labels stored locally so you can record who does what.
• Backups: Export Backup writes a JSON file to a location you choose. It is shared only if you choose to share it.

2. With sync on (opt-in)

Turning sync on and signing in means the following leaves your device.

• Your Google account identity. Signing in with Google gives the app your account's user id, display name and email address, handled by Firebase Authentication. It is used to own your household and to show who is in it. There is no password: the app never sees one.
• Your household's chore data. Homes, rooms, chores, subtasks, schedules and completion history are stored in Google Cloud Firestore so your other devices, and anyone you invite, can see them.
• A random installation identifier. Generated by the app, unique to this install, and used only to decide which of two conflicting edits is newer. It is not an advertising identifier, not a device or hardware id, and is discarded when you uninstall.
• Invite codes. A code you generate is stored so it can be redeemed. It expires after one week and you can replace it at any time, which revokes the previous one.

Who can see it. Only people who are members of your household, and Google as the infrastructure provider. Nothing is sold, shared with advertisers, or used for advertising or profiling.

Where it is processed. Google Cloud Firestore and Firebase Authentication, operated by Google. Their handling is governed by Google's own privacy policy.

3. Permissions

• POST_NOTIFICATIONS: the optional daily reminder about due and overdue chores.
• INTERNET: household sync. Unused while sync is off.
• ACCESS_NETWORK_STATE, WAKE_LOCK, RECEIVE_BOOT_COMPLETED, FOREGROUND_SERVICE: declared by the Android WorkManager library that schedules the reminder.
• READ_GSERVICES: declared by Google Play services, used by Firebase to reach its backend.
• USE_BIOMETRIC, USE_FINGERPRINT: declared by the Android Credential Manager library used for Google sign-in. The app does not itself request a fingerprint or face scan.

4. Retention & deletion

• Local data can be deleted from Settings ("Reset to Defaults"), by clearing the app's storage, or by uninstalling.
• Synced data: leave the household from the Household screen to remove yourself from it. To delete a household's data entirely, delete it as its owner, or email info@niek.li from the address you signed in with.
• Turning sync off stops further transmission. It does not retroactively delete what was already synced; leave or delete the household for that.

5. Children

The app is not directed at children and collects no information about them beyond what an account holder chooses to enter as a chore or a member name.

6. Changes

Material changes to what leaves your device will be reflected here before the version that makes them is released.
