Privacy Policy

Last updated: October 2026

Our Core Privacy Guarantee:TTech processes your data in your browser. We do not upload your text, files, passwords, credit card numbers, or calculation inputs to remote databases.

1. Information We Do Not Collect

When you use our online tools (including the Password Strength Checker, JSON Formatter, PDF Merger, Image Resizer, PII Redaction Tool, or Mortgage Calculator), your entries and files are processed strictly within your local browser environment. We do not save, collect, or transmit your data.

2. Local Browser Storage

We use browser localStorage solely to remember your user interface preferences:

Your preferred color scheme (Dark Mode vs Light Mode).
Your list of recently visited tools for convenient shortcut access on the homepage.

This data never leaves your device and can be cleared at any time via your browser settings or the “Clear history” button.

3. External Queries (DNS & HTTP Checks)

Certain diagnostic network tools (such as DNS Lookup and HTTP Header Inspector) require querying external servers to resolve hostnames. These requests are routed through secure, rate-limited APIs with strict Server-Side Request Forgery (SSRF) filters. No personal identification information is logged.

4. Contact Inquiries

If you submit our contact form or have questions regarding this privacy policy or our data practices, reach us directly at support@ttech.bond. We never share or sell contact information.
