Privacy Policy
Last updated: 2026-11-04
This policy explains what data RenoMath collects and how it is used. It is written to be read, not to be survived.
What we collect
Nothing you type into a calculator leaves your device by default. The calculations run in JavaScript inside your browser and are never sent to a server.
There are no accounts on this site and no form submissions. Nothing is stored in a database, because the site has no database.
Like most websites, our hosting provider records standard server logs — IP address, browser type, referring page and timestamp — for security and abuse prevention. These logs are retained for a limited period and are not linked to any personal profile.
Cookies and advertising
This site is supported by advertising. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
- You may opt out of personalised advertising by visiting Google Ads Settings.
- You can also opt out of third-party vendor cookies for personalised advertising at aboutads.info.
Third-party ad vendors may place and read cookies on your browser, or use web beacons, in the course of serving ads. We do not control those cookies and this policy does not cover them.
Analytics
We may use aggregate analytics to understand which calculators are useful. Analytics data is aggregated and is not used to identify individuals.
Your choices
You can block or delete cookies through your browser settings at any time. Blocking advertising cookies does not affect the calculators, which will continue to work normally.
Children
This site is not directed at children under 13 and we do not knowingly collect data from them.
