Information used when you visit

You can use the site without an account or providing contact details. The site has no contact forms or advertising.

The calculators, solar-system model and chess game run in your browser. The site code does not send your calculator entries or game progress to me, and does not save them in persistent browser storage.

Cloudflare and site traffic

Cloudflare delivers and protects the site and provides its built-in traffic dashboard. When someone visits, Cloudflare processes technical information such as their IP address and the page requested. Its dashboard shows aggregate statistics such as request counts, paths and country summaries.

I use those aggregate statistics to understand overall site traffic. I do not use a Cloudflare Web Analytics or RUM script, and I have not subscribed to Logpush or configured a Logpush export.

For the limited request information used to operate and protect the site and review aggregate traffic, I rely on legitimate interests: keeping this educational site available and secure and understanding its overall use. You can contact me to object to processing based on legitimate interests.

Cloudflare says HTTP request-log retention is off by default. Its separate analytics datasets have their own retention rules; retention can vary by dataset. See Cloudflare’s log-retention guidance and its analytics-retention update.

Cloudflare may use security cookies when its protection features require them. See Cloudflare’s cookie information.

Emails and other providers

If you email me, I receive your email address, message and anything else you choose to include. I use it to reply and handle your enquiry.

The site is published through OpenAI Sites and uses Cloudflare services. Those providers may process technical information to operate and protect the site. Read OpenAI’s privacy policy and Cloudflare’s privacy policy.

Your choices and rights

You do not have to provide personal information to use the site. If you email me, you can ask about personal information relating to your message. Depending on the circumstances, you may also have rights to access, correct, erase or object to the use of your personal information.

For a privacy request, email privacy@physicssolver.co.uk. You can also complain to the Information Commissioner’s Office.
