1. Introduction
Welcome to Num Lines (developed by DV Siam). Your privacy is of paramount importance to us. This Privacy Policy explains how our application operates and outlines our strict commitment to protecting your personal information.
Num Lines is built as a 100% standalone, offline productivity utility. We do not collect, process, track, or share any personal data or text entered into the application.
2. Zero Data Collection & Storage
Specifically:
- No Personal Information: We do not ask for, gather, or store your name, email address, phone number, location, or device identifiers.
- No User Accounts: The app does not require sign-up, registration, passwords, or login credentials.
- No Text Logging: Any text you paste, type, or format remains solely within your device's temporary memory while the app is running and is never transmitted anywhere.
- No Cloud Databases: We do not maintain remote servers or databases for user content.
3. Permissions & System Services
Num Lines respects Android security best practices and requests zero sensitive device permissions.
- No Dangerous Permissions: We do not request Camera, Microphone, Contacts, GPS Location, SMS, Phone State, or External Storage permissions.
- Clipboard Access: The app uses standard Android clipboard APIs solely to allow you to paste input and copy your numbered text when you explicitly tap the "Paste" or "Copy Result" buttons.
- No Internet Permission: The app operates fully offline and does not require an active internet connection for any core formatting functionality.
4. No Advertisements & No Third-Party Trackers
Num Lines is completely ad-free. We do not integrate:
- No Ad networks (e.g., Google AdMob, Unity Ads, AppLovin, etc.)
- No Analytics SDKs (e.g., Firebase Analytics, Google Analytics, Mixpanel)
- No Behavioral tracking, fingerprinting, or marketing beacons
5. Children's Privacy (COPPA Compliance)
Our application is suitable for all ages (3+) and is fully compliant with the Children's Online Privacy Protection Act (COPPA) and Google Play Families Policy. Because we do not collect any personal data from any user, we do not knowingly gather any information from children under 13 years of age.
6. Security of Your Information
Because all calculations and text formatting happen locally on your device with no data leaving the phone, your data is inherently protected by your device's own operating system security architecture.
7. Changes to This Privacy Policy
We may update our Privacy Policy from time to time to reflect any future utility updates or regulatory compliance. Any changes will be posted on this page with an updated effective date.
