PRIVACY POLICY

Cosmic History Timeline · cosmichistorytimeline.com
Effective date: April 22, 2026 · Last updated: April 22, 2026

1. Overview

Cosmic History Timeline ("we", "our", "the site") is an interactive educational visualization available at cosmichistorytimeline.com. This Privacy Policy describes how we handle information when you visit the site. We designed the site to collect as little information as technically possible.

2. Information We Collect

We do not collect, store, or transmit personal information directly. We do not operate a backend database of user data. We do not use Google Analytics or any comparable first-party analytics service.

The site does use your browser's local storage to remember your interface preferences (such as axis visibility toggles, zoom level, and any event edits you make). This data is stored on your device only and is never transmitted to us.

3. Third-Party Advertising (Google AdSense)

This site displays advertisements served by Google AdSense, a third-party advertising network operated by Google LLC.

4. Cookies and Similar Technologies

We do not set any first-party cookies. The only cookies that may be placed on your device through this site come from Google AdSense and its authorized advertising partners, as described above.

Most browsers allow you to control cookies through their settings. You can choose to block or delete cookies at any time. Blocking advertising cookies will not prevent the site from functioning, but you may see less relevant ads.

5. For Users in the European Economic Area (EEA), UK & Switzerland

If you are visiting from the EEA, the United Kingdom, or Switzerland, we rely on Google's Consent Management Platform to obtain your consent before serving personalized advertising. A consent banner will appear on your first visit, allowing you to accept or decline personalized advertising. You may change your preferences at any time by clearing your cookies or using the opt-out links above.

Under the General Data Protection Regulation (GDPR), you have the right to access, correct, or delete any personal data processed about you, to object to processing, and to lodge a complaint with a supervisory authority.

6. For Users in California (CCPA / CPRA)

California residents have the right to know what personal information is collected, to request deletion, to opt out of the "sale" or "sharing" of personal information, and to not face discrimination for exercising these rights. Because we do not directly collect personal information, most of these rights are exercised through Google's advertising preferences.

To exercise your "Do Not Sell or Share My Personal Information" right with respect to Google's advertising on this site, please use Google Ads Settings.

7. Children's Privacy

This site is suitable for general audiences and does not target children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it.

8. External Links

The timeline includes links to Wikipedia articles, Amazon product pages, and other external resources for further reading. When you click these links, you are subject to the privacy policies of those third-party sites. Amazon links on this site use the Amazon Associates affiliate program (tag: cosmictimelin-20); we may earn a small commission from qualifying purchases at no extra cost to you.

9. Data Security

The site is served over HTTPS. Because we do not store user data on any backend, there is no server-side user information that could be subject to a breach.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by an updated "Last updated" date at the top of this page. Continued use of the site after changes are posted constitutes your acceptance of the revised policy.
