Privacy Policy
The short version
The numbers you type into any calculator on this site never leave your browser. They are not transmitted, logged or stored. There is no account system and no database of user figures.
Information we do not collect
- Any value you enter into a calculator — price, cost, income, fee rate.
- Names, email addresses or payment details. There is no signup form.
- Uploaded files, because there is nothing to upload to.
Information that is collected automatically
Like almost all websites, basic technical request data (IP address, browser type, referring page, pages visited) may be processed by the hosting provider and by analytics, in order to keep the site working and understand which pages are useful.
Advertising and cookies
This site is funded by advertising. Third-party advertising partners may set cookies or use similar technologies to serve and measure ads, and in some cases to personalise them based on your prior visits to this and other websites. This site does not pass any calculator input to those partners.
You can opt out of personalised advertising through your browser settings and through the industry opt-out pages operated by advertising associations in your region. Blocking cookies does not stop the calculators working, since they need no cookies at all.
Children
This site is aimed at adults running businesses and is not directed at children under 13. We do not knowingly collect personal information from children.
Your rights
Depending on where you live, you may have rights to access, correct or delete personal data held about you. Because we hold no user accounts and no calculator inputs, in most cases there is no personal data of yours for us to act on — but requests can be sent via the contact page.
Changes
If this policy changes, the "last updated" date above will change with it.
