time-zones.org is committed to your privacy. This policy explains exactly what data is collected, why, and how it is used.
What We Collect
Analytics
We use Google Analytics 4 to understand how visitors use the site — which pages are visited, approximate country of origin, and session duration. This data is aggregated and does not identify you personally. Google Analytics may set cookies on your device. You can opt out at any time using the Google Analytics Opt-out Browser Add-on.
Theme Preference
If you switch between light and dark mode, your preference is stored in your browser's localStorage. This data never leaves your device and is never transmitted to us.
Nothing Else
time-zones.org has no user accounts, no contact forms, no newsletter, and no advertising. We do not collect your name, email address, IP address, or any other personally identifiable information.
Cookies
The only cookies on this site are set by Google Analytics. No first-party cookies are used for any other purpose.

Your Rights
If you are located in the European Union or European Economic Area, you have rights under the GDPR including the right to access, correct, or erase data held about you. Because we do not collect personal data beyond what Google Analytics records anonymously, there is no personal data stored on our side to access or erase. For data held by Google, please refer to Google's privacy controls.
California residents may have additional rights under the CCPA. As we do not sell personal data — and do not collect it beyond anonymous analytics — no further action is required on our part.
Data Retention
Google Analytics data is retained for 14 months, after which it is automatically deleted. We do not retain any other data.
Changes to This Policy
We may update this policy from time to time. The date at the top of this page will always reflect the most recent revision. Continued use of the site after changes are posted constitutes acceptance of the updated policy.
