FreeDevTool is a privacy-first developer toolbox. Every tool runs entirely in your browser. Data you paste, type, or upload into any tool never reaches our servers. We do not run advertising, do not sell data, and do not require an account.
All processing happens client-side using JavaScript. Whatever you enter into a tool — JSON, JWT tokens, text, images, regex patterns, hashes, timestamps, anything — stays on your device. We have no logs of tool inputs because we never receive them. Closing the tab discards the data.
We use Google Analytics 4 to understand which tools developers find useful. The data collected is aggregated and anonymized: pages visited, session duration, browser type, and country-level location. We do not link analytics events to any personal identifier.
The only cookies set on this site are Google Analytics cookies (used to deduplicate sessions). No advertising cookies, no tracking pixels from third parties. You can opt out via the Google Analytics Opt-out Browser Add-on or by blocking cookies for this site.
FreeDevTool does not display advertisements. We do not use AdSense, retargeting, or any third-party ad network. The site stays free because it is lean — no servers process your tool data, so there is nothing to monetize.
This site is served as static files from Cloudflare Pages. Cloudflare receives standard HTTP request metadata (IP, user agent, referrer) for the purpose of delivering the page and protecting against abuse, governed by Cloudflare's Privacy Policy. Fonts are loaded from Google Fonts (Google's Privacy Policy).
Because we never store your tool data and analytics events are anonymized, there is no personal account or profile to access, export, or delete on our end. For data held by Google or Cloudflare, refer to their respective privacy policies linked above.
We may update this policy as the site evolves. The "Last updated" date above will reflect any changes. Continued use of the site after changes constitutes acceptance.
