Privacy policy

The short version

No accounts, no sync, no servers holding your data. Calculator inputs and your subscription ledger stay in your browser — inputs are forgotten after an hour of inactivity. 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 advertising 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. Google Analytics is used for aggregate site measurement with IP anonymization enabled.

Analytics

We use Google Analytics 4 to understand aggregate traffic, page visits and approximate geography. IP anonymization is enabled. Google may use cookies or similar technologies to provide measurement. You can block Google Analytics with Google's opt-out add-on or your browser's privacy controls.

Third parties

Brevo sends alert emails. The eRank vs Marmalead comparison carries an eRank affiliate link, the AMZScout vs Jungle Scout comparison an AMZScout affiliate link, the Helium 10 comparisons Helium 10 affiliate links, and the SellerAmp vs RevSeller comparison a SellerAmp affiliate link; everywhere else there are no affiliate links, sponsored slots, or display ads. If more sponsorships or an ad network join, this page will name them before they go live — and vendor cookies would apply only on their sites, under their policies.

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 alert subscribers get a notice by email. Effective September 5, 2026.
