Privacy Policy

1. Privacy Commitment

At Relationship Lens, we believe your personal messaging history contains some of your most sensitive, private thoughts. Our software is designed specifically to ensure that your raw chat data remains inside your own environment. We run all log parsing and linguistic analyses directly inside your browser so you do not have to worry about database breaches or information sharing.

2. Browser-Side Local Processing

When you select and drop a WhatsApp export file (.txt) or an Instagram messages file (.json) into our website:

  • The file is read in-memory inside your local web browser session using standard HTML5 file reader APIs.
  • Our client-side scripts tokenize, calculate message frequencies, reply gaps, and linguistic parameters in your browser.
  • Your raw message content is never sent to a server. All text reading is kept strictly client-side.

3. Server Analytics and Anonymization

To help us maintain site health, understand scaling demands, and keep track of trending dynamics (such as identifying popular chat archetypes), our application sends a lightweight metadata stats payload to our server (analyze.php) when an analysis is executed. This payload contains:

  • Aggregated numerical stats (e.g. total bubble count, dry-text percentages, median reply gaps, and initiation ratios).
  • Anonymized initials representing the chat partners (e.g., if you analyze a chat between "Sakshi" and "Divyansh", we record strictly S & D). No full names are recorded.
  • A few selected message snippets of less than 220 characters identified as key conversation drivers ("moments"). We do not record any other chat content.

These analytics are logged in a locked, secure local server file (analytics.json) that is blocked from public internet requests using server-level protection rules.

4. Cookies and Web Trackers

We do not load third-party ad networks, social tracking pixels, or cookie-based marketing tools (like Google Analytics, Facebook SDKs, or TikTok pixels) to prevent behavioral tracking of our users. We do not place cookies on your browser.

5. Information Protection

All communication between your browser and our server is encrypted in transit using Secure Socket Layer (SSL) / HTTPS. Server-side log files are hardened against direct external access.

6. Contact & Auditing

Because Relationship Lens runs locally on your browser, you can easily audit our code behavior by opening your browser's Developer Tools (Network Tab) before dropping a file to verify that no raw file contents or message bodies are ever uploaded.
