Privacy

Short version: the tools run entirely in your browser, and what you type into them never leaves your device.

What we don't collect

• Nothing you enter into a tool — no values, dates, or results.
• No accounts, because there aren't any.
• No advertising or cross-site tracking identifiers.

What's stored locally

One preference is saved in your browser's local storage: your chosen colour theme. It stays on your device, is never transmitted, and clearing site data removes it.

Third parties

The site loads its fonts and assets from its own origin. There are no third-party embeds, social widgets or advertising scripts on tool pages.

Changes

If this ever changes — for example if analytics are added — this page will be updated to say exactly what is collected and why, before the change ships.
