Privacy policy
Last updated: October 2026. This page explains what data this website processes, why, and what control you have.
What we collect
The calculator does not send your numbers anywhere. Every figure you type — prices, costs, VAT rates — is calculated inside your own browser. Nothing is transmitted to us, nothing is stored, and nothing is linked to you. Closing the page erases it.
We do not require an account, and we do not ask for an email address or any personal detail to use this site.
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 based on your visits to this site and other sites on the internet.
- You can opt out of personalised advertising by visiting Google's Ads Settings, or opt out of third-party vendor cookies via aboutads.info.
- Where required by law, you will be asked for consent before non-essential cookies are set, and you can change or withdraw that consent at any time.
Analytics
We may use privacy-respecting aggregate analytics to understand which pages are useful — for example, how many people visit a page and roughly which country they are in. This information is not used to identify individuals.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal data, to object to processing, or to opt out of the sale or sharing of personal information. Because we do not collect personal data through the calculator, most such requests relate to cookies set by advertising partners, which can be controlled through the opt-out links above.
Children
This site is aimed at adults running or considering an online shop, and is not directed at children under 13.
Changes
If this policy changes, the revised version will appear on this page with an updated date.

Questions about this policy can be sent to the contact address published in the site footer once the site is live.
