About

tools.nobeldj.page is my personal utility belt: focused calculators, converters and inspectors for developer, embedded, hardware and AI/ML work. Built by Nobel Djessou.

Privacy

• Every tool runs in your browser. Nothing you type or drop on a page is uploaded.
• No accounts, cookies, analytics or third-party scripts. Fonts are self-hosted.
• Tool inputs are remembered in your browser's local storage so they survive a reload. Secrets (tokens, keys) are never stored.
• The site's Content-Security-Policy blocks network requests from tool pages, so this is enforced, not just promised.

Languages

The site is available in English and French. Results keep the decimal point (2.553 mA) as in datasheets and code; inputs accept either a comma or a point.
