The calculators send nothing
Every calculator on this site runs entirely in your browser. Prices, costs, margins, supplier terms — none of it is transmitted, and there is no server-side record of any calculation you perform. There is no account to create and nothing to opt out of.
Share links are the one exception, and only by your choice. Pressing “copy link” encodes your inputs into a URL. That URL leaves your machine only when you send it to someone.
What we do collect
Email addresses, if you subscribe. Stored with the page you subscribed from and a confirmation timestamp. Used to email you when a tariff rate changes. Nothing else, and never sold or shared. Every email carries an unsubscribe link, and unsubscribing removes you rather than flagging you.
Aggregate analytics. Vercel Web Analytics records page views without cookies, without cross-site tracking and without building a profile of you. We can see that a page was viewed. We cannot see who you are.
Nothing else. No advertising pixels, no session recording, no third-party trackers, no cookie banner — because there are no cookies to consent to.
Where subscriber data lives
On our own server, in a Postgres database we operate, in the United States. Not in a third-party marketing platform. Access is restricted to the service credential the subscription endpoint uses; the key that ships to browsers has no read access to the subscriber table at all.
Your rights
Email hello@roasfloor.com to see what we hold about you, correct it, or have it deleted. Deletion means deletion, not deactivation. We answer within seven days; there is no form and no ticket system.
Changes
If this policy changes in a way that affects what we collect, we will email subscribers rather than quietly updating the date at the top.
