LocalFirstTools.com — data tools that never leave your device
No upload — everything runs on your device

Privacy

Tool input — JSON, tokens, hashes, timestamps — is processed with JavaScript in your browser. LocalFirstTools does not receive that text. There is no paste API and no file upload endpoint.

The hosting platform may see ordinary page requests (which page you opened). That is not the contents of the editor. We do not use the tools themselves as a place to collect personal data.

Clipboard and file access happen through your browser, with your permission, and stay on your device.
