Privacy Policy

In short: your measurements never leave your browser. This page explains exactly what we do and don't collect.

What we collect

7TShirts is designed to run entirely client-side for its calculators. The numbers you type into a calculator (chest size, band measurement, foot length, etc.) are processed locally in your browser to compute a result and are not transmitted to or stored on our servers.

We do collect limited, non-identifying analytics data — such as which pages are visited and which calculators are used — to understand how the site is used and to improve it. This does not include the measurements you enter.

Cookies

We use a small number of essential cookies (for example, to remember your dark/light mode preference) and privacy-respecting analytics cookies. See our Cookie Policy for details.

Third parties

We do not sell your data. If we ever integrate third-party services (such as analytics providers or, in the future, optional account features), we will update this policy to disclose exactly what is shared and why.

Your rights

You can clear cookies at any time through your browser settings, which resets any locally stored preferences. If we introduce accounts or saved measurements in the future, you will be able to request deletion of that data by contacting us.

Changes to this policy

We may update this policy as the site evolves. Material changes will be reflected by updating the "last updated" date at the top of this page.
