Privacy
Short version: we collect very little, and we never sell it.
The calculator
Prices and options you enter are calculated in your browser and aren't sent to us. They may appear in the page URL so you can share a result.
Email alerts
If you sign up, we store:
- your email address
- the alerts you picked (fee changes, fee promos, big sales), if any
- the page you signed up from, and the date and time
- a record that you agreed to receive these alerts
We use your email only to send these alerts. We never sell or rent it, and we don't share it with advertisers. It's stored in a Cloudflare D1 database that only SlabRoute can access.
To stop basic abuse, the signup form keeps a short-lived, one-way hash of your IP address. It's never the IP itself, and it's deleted within 24 hours.
Unsubscribe anytime: reply "unsubscribe" to any alert, or use the unsubscribe link in each email. We'll delete your address.
Analytics
We use Cloudflare Web Analytics to count page views and measure page speed. It doesn't use cookies or track you across sites.
Ads and affiliate links
We don't run ad trackers today. Some platform links may become affiliate links, which never change the rankings (disclosure). If we add advertising tags later, we'll update this page and ask for consent where required.
