Privacy Policy

This policy explains what Classic Launcher accesses, what may be sent to service providers, and the controls available to you. The app has no user accounts and is intended for adults and caregivers aged 18 or older.

1. Information kept on your device

The following information is accessed or stored locally for launcher functionality and is not sent to QuantixLab or third parties by the app:

• Contacts selected for Favorites, Speed Dial, and the Contacts screen
• The list of installed launchable apps and adult-configured allowlists
• SOS contact, medical note, caregiver PIN hash, profiles, themes, and launcher settings
• Foreground app package identity used by optional Kid or Focus app blocking

Contacts permission is optional. Contacts are read from Android's Contacts Provider only when needed. Installed apps are queried through Android's standard launcher visibility. The SOS contact and medical note are user-entered convenience fields and do not make the app a health or emergency service.

2. Optional AccessibilityService app blocking

When an adult enables optional Kid or Focus app blocking, a separate prominent disclosure asks for consent before Android Accessibility Settings opens. While current consent, enforcement, and the relevant profile or schedule are all active, the service reads only the package name of the app entering the foreground. It compares that identifier on-device with the adult-selected allowlist and returns a blocked app to the launcher.

The foreground package identity is transient: it is not stored, transmitted, sold, or shared. The service does not retrieve window content, screen text, typed text, passwords, messages, contacts, or communications. It is not an accessibility tool. App blocking is optional and best-effort. Android Settings remains available, and blocking or AccessibilityService access can be disabled at any time.

3. Optional analytics and crash diagnostics

Firebase Analytics and Firebase Crashlytics are off by default. They are enabled only after an adult separately chooses Share analytics, and never while Kid Mode is active. Analytics may process app interactions and device/app information. Crashlytics may process crash logs and diagnostics such as stack traces, device model, operating-system version, and app version. We do not intentionally place contacts, installed-app lists, foreground package identities, SOS details, medical notes, or PINs in analytics or crash events.

You may opt out in Settings at any time. This stops future collection and deletes unsent Crashlytics reports. Data already received by Google may remain under Google's retention rules, and anonymous or aggregated records may not be identifiable for individual deletion.

4. Advertising and consent

The free, non-Kid experience may show Google AdMob banner ads only after Google's User Messaging Platform (UMP) successfully establishes that ads may be requested. Depending on region and choices, Google may collect or share IP-derived approximate location, app interactions, diagnostics, device or other identifiers, and advertising identifiers for advertising, analytics, and fraud prevention. Network or consent-form failures keep ads disabled.

UMP and Mobile Ads are not initialized in Kid Mode, and no ads are requested there. Premium also disables ads. When UMP says privacy options are required, Settings shows Advertising privacy choices, where consent choices can be reviewed or withdrawn. Ads are not requested on Home, Contacts, Call, SOS, or Kid surfaces.

5. Purchases

Google Play Billing processes the one-time premium_lifetime product. Google provides purchase status and a purchase token, which the app caches locally to maintain the entitlement during temporary Play outages. QuantixLab does not receive payment-card details. Google Play may process and retain purchase records under its own policies.

6. Sharing, processing, and security

QuantixLab does not sell your personal information. If enabled or permitted, data described above is processed by Google Firebase, Crashlytics, AdMob, UMP, and Play Billing. Data sent to these services is encrypted in transit. Review Google's Privacy Policy for its processing and retention practices.

7. Kid Mode and audience

The app and its Play Store listing are directed to adults and caregivers aged 18 or older, not to children. Kid Mode is configured and controlled by an adult. While Kid Mode is active, advertising, UMP, Firebase Analytics, and Crashlytics collection remain disabled.

8. Your choices and deletion

• Revoke Contacts or AccessibilityService access in Android Settings.
• Turn off app blocking or optional analytics in app Settings.
• Open Advertising privacy choices when that row is available.
• Delete all local app data by clearing storage or uninstalling the app.

See the Data Deletion Instructions for exact steps and the limits that apply to anonymous third-party SDK data.

9. Changes and contact

We may update this policy as the app or legal requirements change. Material changes will be reflected by the date above. Privacy questions or deletion support requests can be sent to support@quantixlab.dev.
