This Privacy Policy applies to the StreakFast mobile application (the "App"), operated by Clustle Studio ("we," "us," or "our").
In short: StreakFast is built to be private. It has no account, no cloud, no ads, and no analytics or trackers. Everything you log stays on your own device.
None. StreakFast has no analytics, trackers, cookies, or advertising SDKs, and no backend server. We do not automatically collect your device identifiers, advertising ID, IP address, usage or interaction data, or your location.
We do not collect your name, address, precise location, advertising ID, or other personally identifiable information.
The data you enter is used solely to provide the App's features on your device — the fasting timer, records, streaks, charts, and reminders. We use it for nothing else, and we never see it.
We do not:
All your data — including fasting records, weight data, and other information — is stored locally on your device only. We have no servers and do not upload your personal data anywhere. It never leaves your phone unless you choose to export or share it yourself.
We run no analytics and collect no usage data.
Optional StreakFast Pro subscriptions are purchased and managed entirely through Google Play. Payment is processed by Google; the App never receives or stores your payment details. Google's handling of purchase and payment data is governed by Google's own Privacy Policy. You can view, manage, or cancel your subscription at any time in the Google Play Store.
We do not embed any analytics, advertising, or tracking services.
The App does not request location, storage/files, camera, microphone, contacts, or media permissions.
Your data is kept locally on your device until you delete it. It is not stored on any server. Uninstalling the App, or using "Delete My Data" in Settings, removes all locally stored data.
Because we do not collect, store, sell, or share your personal data, the core data-subject rights — access, correction, deletion, and opting out of the sale or sharing of personal information — are fully satisfied by the on-device controls below. We do not sell or share personal information, and we do not use your data for targeted advertising.
Since we hold no server-side data about you, there is nothing on our end to request or delete.
This App is not directed to children under the age of 13. We do not knowingly collect personal information from children.
Your data is stored locally on your device and protected by your device's own security. Because we operate no servers and transmit no personal data, your information is not exposed to server-side breaches.
