Privacy Policy
Effective: November 14, 2026
This policy explains how Calcrift ("we", "us") handles information when you use calcrift.com.
1. Information we collect
We do not require accounts and we have no sign-up or login. Our calculators run entirely in your browser. The numbers you type are not sent to us.
Some tools save your inputs (for example your pet list) in your browser's local storage so they are still there next time. This data stays on your device. You can delete it at any time by clearing your browser's site data.
If you email us, we receive your email address and message and use them only to reply.
2. Hosting and security logs
Our website is hosted by Cloudflare. Like any web host, Cloudflare processes technical data such as IP addresses and browser type to deliver pages and protect the site from attacks. See Cloudflare's privacy policy.
3. Advertising and cookies
We may show ads to keep the site free. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on visits to this and/or other sites on the Internet.
You may opt out of personalized advertising by visiting Google Ads Settings, or opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info. Learn more in How Google uses information from sites that use its services.
Where required by law (for example in the EEA, UK and Switzerland), ads are only personalized after you give consent through a consent message, and you can change your choice at any time.
4. Children's privacy
Our site has no accounts, forms or chat, and we do not knowingly collect personal information from children under 13 (or the minimum age in your country). If you believe a child has sent us personal information by email, contact us and we will delete it.
5. Your rights
Depending on where you live (including under the GDPR and Thailand's Personal Data Protection Act), you may have the right to access, correct or delete personal data we hold about you, and to object to processing. Because we collect almost nothing, most requests can be handled by clearing your browser data. For anything else, email contact@calcrift.com.
6. Changes
We may update this policy. The effective date at the top shows the latest version.
