Nothing you type into the calculator.
List price, product cost, coupon, refund rate, target margin — every input is calculated in your browser. Nothing is sent to a Profit After Fees server. Nothing is stored. Nothing is tied to you.
Privacy
What this site collects, in plain English.
Profit After Fees is a free Stripe fee calculator. There's no signup, no login, no newsletter, and no contact form. The site shows ads from Google, and Google's ad scripts collect their own data. Here's exactly what each side sees.
What Profit After Fees collects
No account. No email. No contact form.
The site has no signup, no login, and no newsletter. Every calculator works without giving up an identifier.
Shared scenarios travel inside the URL.
When you copy a "Share this scenario" link, your inputs are encoded into the URL itself. Anyone who opens that link sees those numbers. Don't paste a share link anywhere you wouldn't paste the numbers themselves.
What Google collects through the ads
Google Ads conversion tag.
The site loads gtag.js from googletagmanager.com using Google Ads ID AW-18121518600. This tells Google whether visits from a Google Ad reached this page. Google sees your IP address, approximate location, device and browser, the page URL, and ad-click identifiers.
Google AdSense.
The site loads AdSense from pagead2.googlesyndication.com using publisher ID ca-pub-3560388500961643. AdSense and its partners use cookies and similar identifiers to pick which ads you see, including ads based on prior visits to this site or other sites. Google sees your IP address, approximate location, device and browser, and ad interactions.
Nothing else third-party.
No Facebook Pixel. No TikTok Pixel. No LinkedIn Insight Tag. No Hotjar. No Segment. The two Google scripts above are the only third-party code this site loads.
How to limit what Google sees
Turn off personalized ads.
Visit Google Ads Settings and switch personalization off. You'll still see ads here. They'll just be less tailored to you.
Clear or block cookies.
You can clear or block cookies for profitafterfees.com from your browser's "Site settings" or "Cookies and site data" panel. Chrome, Safari, Firefox, and Brave all expose this directly.
Block the ad scripts entirely.
A standard ad blocker stops googletagmanager.com and pagead2.googlesyndication.com from loading at all. The calculator still runs without them.
A few other things worth knowing
