Privacy Policy
TL;DR: The tools run entirely in your browser: text and files you use with them are not uploaded or stored; only standard server/CDN logs and sandboxed ad frames exist.

Your content stays on your device
All tools on this site — the Token Counter, LLM Cost Calculator, AI Chat Export, AGENTS.md Generator, MCP Config Generator and JSON Schema Generator — run entirely in JavaScript in your browser. Text you paste and files you open are processed in memory on your device and are never sent to our server.
Local storage
We store two things in your browser’s localStorage: your language choice and the AGENTS.md form values, so they are there when you return. You can clear them at any time in your browser settings.
Server logs
Like any website, our web server and our CDN provider (Cloudflare) may keep standard access logs (IP address, browser, page requested, time) for security and reliability. We do not sell this data.
Advertising and affiliate links
We show display banner ads from Adsterra and A-ADS on some pages. The ads load inside a separate, sandboxed frame from /ads/ on this site, so the ad code cannot read the text or files you use with our tools. The ad networks and their advertisers may use cookies or similar technology in that frame to show and measure ads; see Adsterra's privacy policy. You can block these with any ad or cookie blocker; the tools keep working. Some links are affiliate links that may earn us a commission at no extra cost to you, and they are labelled.
