Environment

Tools on this site generally run in your browser—no install required. You can use them on Windows, Mac, smartphones, and more, though some tools are PC-oriented (not mobile-supported). Viewing the site and first-time use need an internet connection; we do not guarantee site-wide offline use.

Saved data lives in your browser’s LocalStorage. Clearing cache or site data, or switching browsers/devices, can erase it. Please export (“Save”) important data regularly and keep a copy yourself.

🔒 Tool files and inputs are processed and stored in your browser by default; the operator does not collect or keep their contents. We do not use cookies for personal tracking. For improvement only, we measure anonymized page views and tool-usage counts. Some tools may make limited network requests (e.g. public page metadata)—see the Privacy Policy.
