The short version
- MTIS for Android has no account, no login, and no sign-up.
- MTIS has no application server. Your inventory records, photos, and scan results are not uploaded by MTIS.
- No ads or MTIS account. Google ML Kit may send technical diagnostics and usage metrics, as explained below.
- Your inventory records are stored locally in a Room (SQLite) database; photos are kept in app-private storage.
1. Who we are
MTIS (Mechanic Tool Inventory System, "the app") is developed and published by BARAKAH TECHNOLOGIES, INC. For questions about this policy, email [email protected].
2. What data the app stores
Like the iPhone/iPad version, MTIS for Android stores only the information you enter about your tools and equipment: tool details, photos, loan records, maintenance history, toolboxes, and app preferences. All of it is entered by you and stays under your control.
3. Where data is stored
Your inventory records are stored locally on your device in a Room (SQLite) database, and photo files in the app's private storage. MTIS does not use cloud sync or operate an application server, cloud database, or backend API. The separate technical diagnostics collected by Google ML Kit are described in section 7.
4. Camera and photo library
Camera and photo access are used only to attach a photo to a tool, or to read text or a barcode on a label using on-device recognition. Images, recognized text, and scanned codes are processed on your device and are not uploaded by MTIS or ML Kit.
5. Biometric app lock
MTIS offers an optional app lock, off by default, using your device's fingerprint/face unlock or PIN/pattern to open the app after it has been in the background. Authentication is handled by the Android platform's own biometric APIs (BiometricPrompt); MTIS never receives or stores biometric data.
6. In-app purchase
MTIS Pro is an optional one-time purchase (com.barakah.mtis.fullaccess) processed entirely through Google Play Billing — no subscription. MTIS does not collect, see, or store any payment information. Google may process purchase-related data under its own privacy policy.
7. Technical diagnostics and advertising
MTIS does not include advertising or operate its own analytics service. Its Google ML Kit scanning SDK may collect app and device information, per-installation identifiers, and performance or usage metrics for diagnostics and analytics. Google states that this technical data is encrypted in transit and is not shared with third parties. MTIS does not receive these metrics. See Google ML Kit data disclosure. Input images, recognized text, and scan results remain on the device.
8. Children's privacy
MTIS is a tool for tradespeople, technicians, and hobbyists. It is not directed at children and does not knowingly collect data from anyone directly.
9. Changes to this policy
