Billing

The money-back guarantee

If DenyFirst isn't for you, ask for your money back within 30 days of your first payment and we'll refund it in full. No conditions, no questions about what the scans found.

We used to promise a refund only when a scan turned up no leak. We dropped that, because it made your refund depend on our judgement of whether a finding "counted" — and a guarantee you have to argue about isn't one. Before you pay anything, your first scan is free: you see a real report on your own app and decide from there.

To claim, email hello@denyfirst.com from the address on the account, or use the refund action in your dashboard.

Related policies

How we authorize a scan, what data a probe actually reads, where scans execute, and how to report a vulnerability to us are all documented on the Security & trust page. That page is the operative description of what DenyFirst does to a system you point it at.

Our Terms of Service and Privacy Policy are maintained as separate documents. Until they are published here, the commitments that bind us are the ones written on this page and on the Security & trust page.
