Huffle Privacy Policy

Summary

Huffle works entirely on your device. There is no account, no sign-up, no advertising, and no analytics or crash-reporting SDK. Your data is never sent to NexusDigitalLabs. If you choose to turn on the optional Google Drive backup, a copy of your data is saved to a hidden folder in your own Google Drive, which only Huffle and you can use.

Information Stored on Your Device

To work, Huffle stores the following on your device only: the name you give your Huffling, the sessions you log (the type of movement, the time, and an optional duration and note), your streak and progress (XP, evolution stage, streak-freeze tokens), your weekly goal, your reminder time, and which cosmetic item your Huffling is wearing. This information stays on your device. We do not run a server that receives it and we cannot see it.

Notifications

Huffle can send you a daily reminder and occasional streak and comeback nudges. These are scheduled locally on your device. Huffle does not use remote push notifications and does not collect a push or device token. On Android 13 and later you are asked for permission, and you can turn notifications off at any time in your device settings.

Optional Google Drive Backup

If you tap “Connect Google Drive” in Settings, Huffle asks you to sign in with your Google account and to allow access to the app's own hidden application-data folder in your Drive. Huffle uses this to save a backup file of your Huffling data and to restore it on a new phone. Huffle can only see that one folder: it cannot see, read, or change any of your other Drive files. The backup goes directly between your device and Google; it is not sent to NexusDigitalLabs. Huffle shows the email address of the connected Google account inside the app so you can see which account is in use, and does not store or transmit it elsewhere.

You can disconnect at any time in Settings, and you can delete the backup from your Google account (Google Drive → Settings → Manage apps → Huffle). Huffle's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Device Backups

Android may include Huffle's data in your device backup to your Google account, depending on your device settings. That backup is handled by Android and Google under their own terms, not by Huffle.

Advertising, Analytics and Purchases

Huffle contains no advertising, no third-party analytics, and no tracking. It currently offers no in-app purchases. If optional purchases are introduced in the future, this policy will be updated before they are available.

Google Play Diagnostics

If you have opted in on your device, Google Play may collect crash and performance diagnostics (Android vitals) about apps you use, including Huffle. This is collected by Google under its own policies and is available to us only in aggregate through the Play Console.

Data Retention & Deletion

Because your data lives on your device, you control it. Uninstalling Huffle, or clearing its storage in your device settings, removes it from the device. If you used Google Drive backup, you can also remove the backup from your Google account as described above. We hold no copy of your data, so there is nothing for us to delete on our side.

Your Rights

Depending on where you live (including under GDPR and CCPA), you may have rights to access, correct, delete, or restrict personal data. Since we do not hold your Huffle data, these are exercised directly on your device and in your Google account. You can still contact us with any question or request.

Children's Privacy

Huffle is not directed at children under 13 and we do not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated date.
