Last updated: May 2026. We keep this short and in plain English.
The short version: We collect minimal data, we don't sell it, and we use it only to run the site and send you the emails you asked for. The longer version is below.
This privacy policy applies to PhysicsFundamentalsInfo, accessible at physicsfundamentalsinfo.com. If you have questions, contact us at contact@physicsfundamentalsinfo.com.
We collect two kinds of information:
We use the information we collect to: deliver the newsletter you subscribed to, respond to your messages, understand how visitors use our site so we can improve it, and maintain the security and functionality of the website. We do not use your data for any purpose you wouldn't reasonably expect.
We use cookies for two purposes: essential cookies that make the site function, and analytics cookies that help us understand site usage. You can disable cookies in your browser settings, though some features may not work as well. We do not use cookies to track you across other websites for advertising.
We rely on a few trusted third-party services to operate: an analytics provider (such as Google Analytics) to understand site usage, an email service provider to send our newsletter, and our web host to serve the site. Each of these has its own privacy policy. We share only the minimum data necessary for these services to function.
If we display advertising in the future, ad partners may use cookies to show relevant ads. We will update this policy and provide appropriate consent mechanisms before doing so. As of the last update, we do not display third-party advertising.
You have the right to access the personal data we hold about you, request correction or deletion of your data, unsubscribe from our emails at any time (every email has an unsubscribe link), and ask us questions about how your data is handled. To exercise any of these rights, email us at contact@physicsfundamentalsinfo.com.
We keep your email address for as long as you remain subscribed. If you unsubscribe, we remove you from our active list. Contact form messages are retained only as long as needed to resolve your inquiry. Analytics data is retained in aggregated form according to our analytics provider's standard retention periods.
Our site is educational and suitable for all ages, but we do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact us and we will delete it.
We may update this privacy policy from time to time. When we do, we'll revise the "last updated" date at the top. Significant changes will be communicated to newsletter subscribers by email.
Questions about this policy or your data? Email contact@physicsfundamentalsinfo.com and we'll get back to you.
