Privacy Policy
Last updated: November 2026
This policy explains what information Plainsum ("we") collects and how it is used.
Information you enter
Numbers and dates you type into calculators are processed in your browser and are not sent to or stored on our servers.
Analytics
We use Google Analytics to understand which pages are visited and how the site is used. It collects information such as pages viewed, approximate location, device type, and referring site through cookies or similar technologies. This information does not directly identify you. You can opt out with the Google Analytics opt-out browser add-on.
Advertising
We may show ads served by Google AdSense or other ad partners. 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 based on visits to this site and other sites on the internet. You can opt out of personalized advertising in Google's Ads Settings, and learn about other choices at aboutads.info or youronlinechoices.eu. Learn more about how Google uses information from sites that use its services.
Consent in Europe and the UK
When ads are shown, visitors in the European Economic Area, the United Kingdom, and Switzerland are asked for consent through a Google-certified consent message before ads use cookies for personalization. You can change your choice at any time from the privacy link shown with that message.
Your choices and rights
You can block or delete cookies in your browser settings. Depending on where you live, such as California or the European Economic Area, you may have rights to access, delete, or opt out of the sale or sharing of personal information. Because we don't collect names, emails, or account data through the calculators, most requests can be handled through your browser's cookie controls and the ad settings above. For other questions, contact us at [email protected].
Children
This site is not directed to children under 13, and we do not knowingly collect personal information from them.
Changes
We may update this policy. The date at the top shows when it last changed.
