Privacy Policy

The short version

This page sets out the detail, including the things that are true of any website and are worth stating plainly.

What is collected

Through the tools: nothing

The tools are client-side JavaScript. Input never leaves your device. You can confirm this by opening your browser’s Network tab while using any tool, or by disconnecting from the internet and continuing to use the page.

Server logs

Like any website, the hosting provider records standard request logs: IP address, timestamp, requested URL, referrer and user agent. These are generated by the web server, are used for security and diagnostics, and are retained for a limited period by the host. They are not used to build profiles and are not combined with anything else.

Local storage

Some tools remember preferences — a chosen encoding, an output format — using your browser’s localStorage. This data stays on your device, is never transmitted, and can be cleared at any time through your browser’s site data settings.

Cookies

This site sets no cookies of its own.

Third parties

There is exactly one:

• Hosting. The provider serving these files necessarily processes the request, including your IP address, in order to deliver the page.

Nothing else is loaded from anywhere else. The stylesheet, the scripts, the fonts (your system’s own) and every photograph are served from this domain. The photographs come from Pexels, but they are downloaded once when the site is built and re-encoded here rather than hot-linked, so viewing a page makes no request to Pexels either — see the photo credits. Open your browser’s network tab on any page and count the domains: there is one.

There are no advertising networks, no analytics scripts, no social media widgets, no chat widgets, no A/B testing tools, no CDNs and no tag managers on this site.

Your rights

Under the GDPR, the UK GDPR and comparable frameworks you have rights of access, rectification, erasure, restriction, portability and objection in relation to personal data held about you.

In practice, because no personal data is collected through the tools and no accounts exist, there is generally nothing held to exercise those rights against. If you have contacted us by email, that correspondence is personal data and you may request its deletion at any time.

Requests and questions go to the contact page.

Children

This site is a general-audience reference and tool collection. It does not knowingly collect personal information from anyone, including children under 13 or 16, because it does not collect personal information at all.

Changes to this policy

If this policy changes materially — for instance if analytics were ever added — the change would be reflected here and the modification date updated. Given the design of the site, substantive change is unlikely.
