PRIVACY
Your learning, your privacy.
You can use Physics Crest without an account or payment. We do not include advertising or add an analytics service to the website.
Progress stays in your browser
Saved resources, the last lesson visited and some lesson progress use browser storage. These are not sent to an academy account or synced across devices. Clear this site's browsing data in your browser settings to remove them. Some lessons offer files you can download to your own device.
Contact and error reports
Contact links open your email app. Nothing is sent until you choose to send it. Messages to contact@physicscrest.com are forwarded through Cloudflare Email Routing to our email provider. If you email us, those services process your email address and message to deliver it. Send only the topic, question number and description of the issue; please leave out student names, scores and other personal information. Contact us if you want a message you sent removed from our mailbox, subject to the email provider's retention processes.
Younger learners
You can learn without providing your name, age or email address. If you are under 13, ask a parent, guardian or teacher to contact us on your behalf. Teachers should not send student records through the contact address.
Hosting and external links
Physics Crest is hosted on Cloudflare Pages. Cloudflare may process connection information, including IP addresses and technical request data, to deliver and protect the website. This is separate from the learning progress saved in your browser. Read Cloudflare’s privacy policy for information about its services. External websites and email providers have their own privacy practices.
