Frequently Asked Questions

Everything you need to know about privacy, security, and offline usage.

Are my files, passwords, or tokens sent to any server?

Absolutely not. There is no backend server or cloud API attached to this suite. Calculations and encryptions happen entirely inside your browser's memory sandbox.

Is the AES-GCM file encryption cryptographically secure?

Yes. The tool utilizes the native W3C Web Crypto API with 256-bit AES-GCM and PBKDF2 key derivation running 100,000 SHA-256 iterations with unique random cryptographic salts and initialization vectors.

Does the audio and screen recording save copies anywhere?

No. MediaRecorder streams write audio and video frames directly into in-memory Blob objects within your local browser session. Nothing is ever uploaded or retained.

Can I bookmark specific tools directly?

Yes. The application uses clean hash-based deep linking (e.g. #/tool/json-to-types or #/tool/qr-studio), allowing you to bookmark or share any of the 50 utility tools directly.
