This Privacy Policy explains how Extremetica (“we,” “us,” or “our”) collects, uses, and protects information when you visit extremetica.com (the “Site”). By using the Site, you agree to the practices described here.
1. Information we collect
Information you give us
When you use our contact form, we collect the name, email address, and message you provide. We use this solely to read and respond to your message.
Information collected automatically
Like most websites, we and our service providers automatically collect certain technical information when you visit, which may include your IP address, browser type and language, device type, referring pages, the pages you view, and the dates and times of your visits. This is used to operate the Site, understand aggregate usage, and protect against abuse.
2. Cookies and similar technologies
The Site may use cookies and similar technologies for the following purposes:
- Essential — required for the Site to function.
- Analytics — to understand, in aggregate, how visitors use the Site so we can improve it.
- Advertising — if and when we display advertising, our advertising partners may set cookies to measure and personalize ads.
You can control or delete cookies through your browser settings. Disabling some cookies may affect how parts of the Site work.
3. Third-party services
We rely on third parties to operate the Site, and they may process the technical information described above under their own privacy policies:
- Analytics providers, to measure aggregate traffic and usage.
- Advertising partners, if advertising is shown on the Site, which may use cookies and device identifiers to serve and measure ads. Where required, you will be presented with choices about advertising cookies.
- Hosting and security providers, which process server logs to deliver and protect the Site.
Our interactive tools display public scientific data sourced from the NASA Exoplanet Archive and similar repositories. That data contains no personal information about you, and querying it does not transmit your personal information to those repositories from this Site.
4. How we use information
- To operate, maintain, and improve the Site and its tools.
- To respond to messages you send us.
- To analyze aggregate usage and performance.
- To detect, prevent, and address technical issues, fraud, or abuse.
- To comply with legal obligations.
5. Legal bases and your rights
Depending on where you live, you may have rights over your personal information, including the right to access, correct, delete, or restrict its use, and to object to certain processing. Residents of the European Economic Area and the United Kingdom have these rights under the GDPR; residents of California have rights under the CCPA/CPRA, including the right to know what is collected and to opt out of the “sale” or “sharing” of personal information. We do not sell personal information for money. To exercise any right, contact us using the details below; we will respond as required by applicable law.
6. Data retention
We keep contact-form messages only as long as needed to handle your inquiry and any reasonable follow-up, then delete them. Server logs and aggregate analytics are retained for limited periods consistent with operating and securing the Site.
7. Children’s privacy
The Site is not directed to children under 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal information from them. If you believe a child has provided us information, please contact us and we will delete it.
8. Security
We take reasonable measures to protect information, but no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
9. International visitors
The Site is operated from the United States. If you access it from elsewhere, your information may be processed in the United States, where data-protection laws may differ from those in your country.
10. Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above. Significant changes may be highlighted on the Site.
