Privacy policy

Last updated: 2026-11-14

Short version

• There is no login and no account. We do not ask for your name, email or phone number. (The contact form lets you give them if you want a reply.)
• What you type in a search or tool box is used inside your browser. It is not sent to us.
• The site shows advertisements from Google. Google and its partners use cookies to show and measure ads, as explained below.

Advertising and cookies

This site uses Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your earlier visits to this and other websites. Google's advertising cookies let it and its partners show you ads based on those visits. You can turn off personalised advertising at Google Ads Settings, or opt out of many vendors' cookies at aboutads.info. How Google uses information from sites that use its services: policies.google.com/technologies/partner-sites. Where the law requires it, Google shows a consent message before using cookies.

What your browser keeps

The site remembers your light or dark choice and, where a page says so, things you saved or looked at recently, in your own browser storage. You can clear them by clearing the site data in your browser.

Other services this site loads

• Google Fonts, for the lettering.
• GitHub Pages, which hosts the pages and, like any web host, sees your IP address when it serves them.
• A sponsored card on some pages: a plain link and picture. If you tap it you go to the sponsor's site, which has its own privacy policy.

Messages you send us

The contact form sends what you type (your message, and a name, email or phone number only if you give them), with the address of the page you sent it from, to us by email through FormSubmit (formsubmit.co), a form delivery service, which may keep a copy for a short time. We use a message only to deal with it and to reply. Nothing is sent until you press Send.

Children

The site is for a general audience and does not knowingly collect personal information from anyone, including children.

Changes and contact

If this policy changes, the new text and date appear on this page. Questions: contact us.
