Privacy Policy
Last updated: October 27, 2026
1. 100% Local Processing
All calculators, converters, generators, and PDF/image utilities in Codex Tools run entirely in your own browser or device. No documents, PDFs, images, JWT tokens, passwords, or financial figures entered into the tools are ever uploaded to external servers.
2. On-Device Storage
The application uses browser local storage (localStorage and Service Worker Cache) solely to remember your theme preference, ad display preference, and to support offline PWA/TWA operation.
3. Advertising (Google AdSense)
When enabled, the website displays subtle ad slots powered by Google AdSense. Google may use cookies or advertising identifiers to serve relevant ads and measure campaign performance in accordance with Google's Privacy Policy. You can collapse or hide ads for the entire day directly from any ad slot header.
4. Contact & Open Source
The source code of all tools can be inspected at github.com/thecodecodex/tools.
