Privacy

Last updated: 2026.

What we collect

Nothing personal. Every tool on MonoTools runs entirely in your browser. The text, JSON, tokens or other input you paste is processed locally and is never uploaded to a server.

Local preferences

Favorites, recent tools, theme choices and workflow history are stored in your browser so the site feels faster when you return. Favorites are saved to local storage by default. A favorites cookie is written only after you explicitly choose “Allow favorite cookie” in the consent dialog, and you can choose “Keep local only” instead.

Analytics

We may use a privacy-respecting analytics service (such as Cloudflare Web Analytics or Plausible) to count anonymous page views. No cookies are set and no personal information is collected.

Advertising

Advertising is disabled unless the production environment explicitly enables it. If Google AdSense is enabled, ad code may use cookies and similar technologies to serve and measure ads. Ads are kept outside the tool input and output areas so pasted content remains local to your browser tools.
