What we collect
Nothing you type into a calculator. All calculations run in JavaScript on your device. The numbers and text you enter are not sent to us or anyone else.
No cookies, analytics or advertising. The site doesn't set cookies, doesn't use analytics services, and doesn't load ad, tracking or social media scripts.
Your theme choice. If you use the "Switch theme" button, your choice (light or dark) is saved in your browser's local storage so the site remembers it. It never leaves your device, and you can clear it in your browser settings.
Server logs. Like any website, the hosting infrastructure (Cloudflare) processes technical data such as IP addresses to deliver pages and protect against abuse. We don't use this to identify or profile visitors. See Cloudflare's privacy policy for how it handles such data.
Email. If you email us, we receive your address and whatever you write. We use it only to reply and keep it no longer than needed for that.
What we don't do
We don't sell, rent or share personal data. We don't build profiles. We don't use your data to train anything.
The previous app on this domain
abfinal.com previously hosted a Shopify app run by a different business. We have no access to data that app collected and are not responsible for it.
Your rights
Depending on where you live, you may have rights to access, correct or delete personal data held about you. Since we hold almost none, the practical case is email: ask and we'll delete our correspondence with you. Write to contact@abfinal.com.
Changes
If this policy changes, we'll update the date above. We won't start collecting personal data without saying so clearly on this page first.
