Privacy Policy

1. Introduction & Mission

This Privacy Policy governs the mobile application Pattern. Pattern is engineered specifically as a self-contained, air-gapped developer workbench.

Many online regex and string formatting tools inadvertently capture confidential source code, server configuration files, private keys, and user payloads. Pattern was created to eliminate this security vulnerability: 100% of all regex evaluations and string transformations take place in your device's volatile RAM without network interaction.

2. Absolute Zero Data Collection

Pattern adheres to an absolute Zero-Data-Collection standard:

• No User Payload Collection: The text you paste, type, or evaluate inside Pattern is never stored on an external server, logged to telemetry, or transmitted.
• No PII Collection: We do not ask for or collect names, emails, phone numbers, or physical identifiers.
• No Analytics / Device Fingerprinting: Pattern does not read hardware IDs, advertising IDs (AAID/GAID), MAC addresses, or IP addresses.

3. Device Permissions Policy

Pattern declares ZERO permissions in its manifest:

• NO Internet Permission: The application is blocked by the OS from opening network sockets or making HTTP/HTTPS calls.
• NO Storage / Files Permissions: The app does not request permission to read your documents or external media storage.
• Native Clipboard Integration: When you tap “Copy”, the app uses standard user-initiated clipboard buffers. No clipboard monitoring happens in the background.

4. Third-Party Code & Advertising

Pattern contains no advertising SDKs, commercial tracking frameworks, behavioral monetization scripts, or crash reporting services.

5. Data Retention & Erasure

Because Pattern operates in-memory, closing or killing the application instantly purges the evaluated text buffers from volatile memory. Any cached form inputs can be purged permanently by clearing the application storage via Settings → Apps → Pattern → Storage → Clear Storage, or by uninstalling the app.

6. Children's Privacy (COPPA & GDPR-K)

Pattern is a technical utility that does not collect any data from any users, including children under 13 (COPPA) or 16 (GDPR-K). It is completely safe and private for student and educational use.
