Privacy Policy

Last updated: 29 October 2026

Sellridge is a set of free calculators for ecommerce sellers. This page explains what data is and is not handled when you use it.

What we do not collect

Every calculation runs locally inside your browser using JavaScript. The prices, costs, fees and return rates you type are never transmitted to a server, never stored, and never associated with you. There is no account, no login and no profile.

What may be collected

Cookies

The calculators themselves do not set cookies. Any cookies present would come from analytics or advertising services described in this policy, and can be blocked in your browser settings without affecting the calculators.

Third parties

The site is served through a content delivery network. If advertising is displayed in future, advertising partners may set their own cookies subject to their own policies. This page will be updated before any such change takes effect.

Your rights

Because we do not store personal data from the calculators, there is generally nothing to access, correct or delete. For questions about server logs or analytics, contact us using the details below.

Children

This site is intended for business use and is not directed at children under 13.

Changes

If this policy changes, the update date at the top of this page will change as well.
