Stellar Focus is designed to keep your focus-session and galaxy data on your device. If account registration is enabled, we use account information only to create and manage your account. We do not sell or share your personal information.
Stellar Focus stores focus-session and galaxy data locally on your device. If account registration is enabled, we collect the email address and username you provide to create and manage your account.
Your date of birth is used only on your device to confirm that you are eligible to create an account. Users under 13 cannot create an account. Your date of birth is not stored or transmitted to us.
The following data is stored locally on your device only:
The following data is not transmitted to us:
We do not use your app data on any server because we do not have access to it. The local data listed above stays on your device and is used only to make the app function.
For example:
Account data is used only for account creation and sign-in. Focus-session and galaxy data is not processed on our servers. No personal data is sold or used for advertising.
Stellar Focus includes an optional app blocking feature. This feature is only used when you choose to enable it.
The app may request access to usage statistics through Android's "Usage access" system setting. This permission is used to detect when a blocked app comes to the foreground during an active focus session.
This information is used only on your device and only for the purpose of enforcing an active focus session. It is not sent to us, not sold, and not shared with third parties. Your blocked-app list is stored locally on your device and is not accessible to us as developers.
The app uses Apple's Screen Time framework, including FamilyControls and ManagedSettings. App selection is handled through Apple's FamilyActivityPicker, a system interface designed so that developers cannot see the specific apps selected by the user. We only receive an opaque token from Apple. We do not know which apps you blocked.
Stellar Focus uses Supabase for account registration and sign-in if accounts are enabled. Stellar Focus v1.0 does not integrate third-party analytics tools, advertising networks, tracking SDKs, or third-party crash reporting SDKs. There are no Firebase Analytics, AdMob, Crashlytics, Mixpanel, Amplitude, or similar integrations in this version.
App stores and operating systems, such as Google Play, Android, iOS, or the App Store, may provide platform-level diagnostic or crash information according to their own privacy settings and policies. Stellar Focus does not add its own third-party analytics or crash reporting service.
If additional third-party services are added in a future version, this Privacy Policy will be updated. If any future feature causes focus-session or galaxy data to leave your device, we will notify you in-app before that feature is activated and, where required, ask for your consent.
Stellar Focus is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13.
If account registration is enabled, the date of birth entered during registration is used only on your device to confirm that you are eligible to create an account. Users under 13 cannot create an account. Your date of birth is not stored or transmitted to us.
Because Stellar Focus does not transmit focus-session, galaxy, or birth-date data to us, we do not knowingly receive personal information from children under 13 through the app.
The app is intended for general audiences, especially students and knowledge workers aged 13 and older. It contains no violence, adult content, or inappropriate material.
Your app data is stored locally on your device for as long as the app is installed, unless you delete it earlier.
You can delete all local app data at any time using one of these methods:
There is no server-side focus-session or galaxy data to delete because that app data is not sent to our servers. Deletion of local data is immediate and irreversible. We have no copy of your local app data and cannot restore it.
Account deletion: To request deletion of your Supabase account (email address and username), use Settings → Request Account Deletion in the app, or email stellarfocus.support@gmail.com with the subject "Account deletion request." You can also submit a request via our account deletion page. We will process account deletion requests within 30 days.
Your app data is stored in a local SQLite database on your device. The database is protected by your device's own security model, such as app sandboxing and device-level encryption where available.
We do not apply additional application-level encryption to the local database in this version.
Because your app data stays on your device, the primary security boundary is your device's own lock screen and operating system security. We recommend keeping your device locked and your Android or iOS software up to date.
We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page reflects the most recent change.
We will notify you of material changes in-app before they take effect where appropriate.
If we ever add cloud sync, analytics, advertising, or any feature that causes app data to leave your device, that change will not happen silently. We will update this Privacy Policy and, where required, ask for your explicit consent before activating that feature.
Because Stellar Focus does not receive or store your focus-session or galaxy data on our servers, we cannot access, export, correct, or delete your local app data for you. You remain in control of the data stored on your own device.
You can exercise control over your data in the following ways:
You can view your local data inside the app, such as your session history, galaxy, achievements, missions, and preferences.
You can delete all local app data at any time through Settings → Reset All Data, through your device settings, or by uninstalling the app. To delete your Supabase account (email and username), use Settings → Request Account Deletion or contact stellarfocus.support@gmail.com.
Stellar Focus v1.0 does not currently provide a built-in export feature. Your data remains stored locally on your device. We may add an export option in a future version.
Where the app provides editing features, you can correct supported local data directly inside the app.
We do not sell personal information. We do not share personal information with third parties. We do not use app data for advertising or tracking.

We aim to respond to privacy-related inquiries within 5 business days.
