Privacy Policy
Last updated: 2026-04-21
1. Summary
Renomath is a static calculator site. We do not require an account. We do not store the inputs you type into any calculator on a server — calculation happens in your browser and URL parameters. We use privacy-respecting analytics and, in the future, will serve third-party advertising via Google AdSense.
2. Information we collect
- Request logs. Our hosting provider (Cloudflare) records standard web-server logs — IP address, user agent, referrer, request path, timestamp — for security, fraud prevention, and uptime monitoring. These logs are retained for up to 30 days.
- Analytics. We use aggregate, cookie-less analytics to understand which calculators are popular. No individual user profile is created.
- Calculator inputs. Inputs you type into a calculator may be reflected in the page URL so you can share the result. They are not transmitted to our servers as user-identifying data.
3. Advertising (planned)
Renomath plans to display advertising provided by Google AdSense. When ads are live:
- Google and its partners use cookies to serve ads based on prior visits to this and other websites. See Google's advertising policy.
- You may opt out of personalised advertising by visiting Google Ads Settings.
- You may also opt out of some third-party vendor's use of cookies at aboutads.info.
4. Cookies
Until ads are enabled, Renomath sets no tracking cookies. Session cookies used by the hosting layer (Cloudflare) for security and bot protection may be set; these do not identify you as a user.
5. Your rights (CCPA / GDPR)
California residents have the right to know what personal information is collected about them and to request deletion. EU/UK residents have analogous rights under the GDPR. Because we do not maintain user accounts or store identifiable calculator inputs, most requests reduce to a hosting-log lookup.
Submit requests to privacy@renomath.co. We respond within 30 days.
California residents may also exercise their "Do Not Sell or Share My Personal Information" right. Renomath does not sell personal information. If ads are enabled in the future, some third-party cookies may be considered "sharing" under CCPA — use the Google Ads Settings link above to opt out, and email privacy@renomath.co to record your preference site-wide.
6. Children's privacy
Renomath is not directed at children under 13, and we do not knowingly collect information from them.
7. Changes to this policy
We'll update this page with a new date at the top whenever material changes are made.
