Privacy policy

The short version

Calculators work without an account and your inputs stay in your browser. If you create a free account, your ledgers sync to our database so they follow you across devices. If you join fee alerts, your email goes to our newsletter provider. That's the whole list — we sell nothing and share nothing.

What we collect

Almost nothing. Calculator inputs and your subscription ledger live in localStorage on your device only, and calculator inputs are forgotten after an hour of inactivity.

Fee alerts: your email address, stored with Brevo, the moment you subscribe on this site. Unsubscribe anytime with one click in any email.

What we never collect

No accounts, no advertising trackers, no cross-site cookies, no fingerprinting, no sale of personal data — to anyone, ever. Fee math runs entirely in your browser; we operate no servers that could see the numbers you type.

Third parties

Brevo sends alert emails. Affiliate links to seller tools (see our disclosure) may set the vendor's own cookies when you click through — that happens on their site, under their policy. A future ad slot will come from one privacy-friendly network and this page will name it before it goes live.

Your rights

Clear your browser storage anytime to erase everything FeeStrip keeps. To leave the newsletter, unsubscribe in any email. For any other request — including EU and UK GDPR access, correction, deletion and portability rights — email hello@feestrip.com and it will be done within 30 days.

Children

FeeStrip is built for adult sellers. We knowingly collect nothing from children under 16.

Changes

If this policy changes materially, the new version ships here with a new effective date, and account holders get a notice by email. Effective September 5, 2026.
