Pricing questions
A check is one scored session - one answer to "who is this?". Every time your backend verifies a session with Foil, that’s a check. Page views, signal collection, and dashboard usage don’t count.
The Free plan stops at 100 checks per month. Checks resume on the first of the next month, or immediately when you upgrade to Pro. We never bill the Free plan for going over.
Pro includes 20,000 checks a month. Past that, each check is $0.05 and lands on your next invoice. Your traffic is never cut off mid-month, and the dashboard shows the projected overage as it accrues.
No. Checks made with a test-mode API key are always free and never count toward your plan’s included usage.
Yes. Upgrades take effect immediately and are prorated. You can manage your card, billing details, and cancellation from the dashboard at any time.
We publish a Data Processing Addendum at usefoil.com/dpa, and we’re happy to share audits, policies, and procedures. Ask us through the contact page.
