Privacy Policy

Short version: the calculators run in your browser, we don't ask for personal information, and we don't sell data.

Last updated: September 29, 2026

What the calculators do with your inputs

Everything you type into a calculator is processed by JavaScript in your own browser. Your measurements are not sent to us. To make results easy to share, the calculator writes your inputs into the page address (for example ?L=10&W=12); that address stays on your device unless you choose to share it.

Information we collect

We don't ask you to create an account and we don't collect names, addresses or payment details. If you email us, we receive your email address and whatever you include in your message, and we use it only to reply.

Cookies and similar technologies

At the moment this site doesn't set cookies and doesn't use analytics or advertising services. If that changes, we'll update this policy before the change takes effect and, where required by law, ask for your consent first.

Hosting and server logs

The site is served by a third-party hosting provider. Like any web server, it may process technical information such as your IP address, browser type and the pages requested, in order to deliver the site and protect it against abuse. That processing is governed by the hosting provider's own privacy policy.

Our pages sometimes link to manufacturers, suppliers or public agencies. We're not responsible for their privacy practices, so please read their policies.

Children

This site is intended for a general adult audience and isn't directed at children under 13.

Your rights

Depending on where you live — for example in the EU, the UK or California — you may have the right to access, correct or delete personal information we hold about you. Because we hold almost none, the simplest way to exercise these rights is to email hello@sizemyproject.com.

Changes to this policy

We'll post any changes on this page and update the date at the top.
