Privacy Policy
Last updated: July 14, 2026
This Privacy Policy explains how periodictable.study ("we", "us") handles information when you visit https://periodictable.study (the "Site"). We keep things simple: the Site is a free reference tool and we do not ask you to create an account or submit personal information.
Information we collect
We do not directly collect names, email addresses, or similar personal details. We use third-party services that may automatically collect standard technical information such as your device type, browser, approximate location (from IP address), pages viewed, and interactions, using cookies and similar technologies.
Cookies and analytics
We use Google Analytics to understand how the Site is used (for example, which elements and features are popular) so we can improve it. Google Analytics sets cookies that collect usage data in aggregate. You can learn more at Google's Privacy Policy.
Advertising (Google AdSense)
We display ads through Google AdSense to keep the Site free.
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to the Site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info/choices.
Your choices and consent
When you first visit, a banner lets you Accept or Reject analytics and advertising cookies. We honor your choice using Google Consent Mode, and you can change it any time by clearing this site's data in your browser. You can also block or delete cookies in your browser settings.
Your rights (GDPR / UK GDPR)
If you are in the European Economic Area or the United Kingdom, you have rights to access, correct, or delete personal data, to object to or restrict processing, and to data portability. Because we do not hold account data, most requests concern data processed by Google; you can exercise many choices directly through the Google links above or by contacting us.
Your rights (California / CCPA)
California residents may request information about, or deletion of, personal information and may opt out of the "sale" or "sharing" of personal information as defined by the CCPA/CPRA. We do not sell personal information; advertising cookies may constitute "sharing" for interest-based ads, which you can opt out of using the links above.
Children's privacy
The Site is intended for a general audience of students and is not directed to children under 13. We do not knowingly collect personal information from children under 13.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above.
