Privacy Policy
This policy explains what information SimpleProfitCalc.com collects and how it is used. The short version: the calculators run entirely in your browser, and we collect as little as possible.
Calculations stay on your device
Every calculator on this site runs in your web browser. The numbers you enter are not sent to our servers, stored, or shared with anyone. When you close the page, they are gone.
Information you choose to send us
If you contact us by email, we receive your email address and whatever you write in your message. We use it only to reply to you, and we do not add you to mailing lists or pass it to third parties.
Cookies and analytics
We may use privacy-respecting, aggregated analytics to understand which calculators are useful and how the site performs. We do not use advertising trackers, and we do not build profiles of individual visitors.
Your rights
Under UK data protection law (UK GDPR), you can ask us what personal data we hold about you, request a copy, or ask us to delete it. Because we hold so little, this is usually just your email correspondence. To make a request, contact us.
Changes to this policy
If we change this policy we will update this page. This policy was last updated in 2026.
