Privacy policy

Last updated 16 October 2026. The short version: FeeFellow has no accounts, the calculators run entirely in your browser, and we do not sell data about anyone, ever.

What the calculators do with your numbers

Nothing leaves your device. Every FeeFellow calculator runs in your browser using JavaScript on the page. The prices, costs and margins you type in are never sent to a server, never stored by us, and are gone when you close the tab.

What we collect

Aggregate analytics. We use Cloudflare Web Analytics, a cookie-free service that reports overall page views and approximate visitor countries so we know which tools are useful. It does not set cookies, does not fingerprint your device, and does not build a profile of you.
Standard server logs. Our host (Cloudflare) keeps routine technical logs, such as IP addresses and browser types, for security and abuse prevention, as every website does.
Email you send us. If you contact us, we receive your email address and whatever you write, and we use it only to reply and to fix any problem you reported.

What we do not do

No user accounts and no signups, so no passwords or profiles to protect or leak.
No sale, rental, or sharing of personal information with data brokers or advertisers.
No advertising cookies or cross-site tracking pixels on this site.

Payments and affiliate links

The paid template bundle is sold through Lemon Squeezy, which acts as merchant of record: it collects your payment details under its own privacy policy, and we never see or store your card information. Some pages link to third-party seller tools under affiliate programs; if you click one, that site may set its own cookies and will know you arrived from FeeFellow. Those sites are governed by their own privacy policies.

Advertising

If display advertising is added to this site in the future, this policy will be updated first, before any ad code ships, to describe the provider and the choices available to you.

Your choices and contact

Because we hold almost nothing, there is usually nothing to delete, but if you emailed us and want that correspondence removed, ask via the contact page and it will be deleted. Questions about this policy go to the same place.
