Refund Policy

Last updated: May 19, 2026

Short version: we do not offer refunds. If you are unhappy with Vulkro, email [email protected] and we will do what we reasonably can to make it right.

Why no refunds​

A Vulkro license is a cryptographically signed .lic file we hand to you after payment. The signature is verified locally by the binary, on your machine, without any check-in to our servers. There is no kill-switch on our end. Once we issue a .lic, we cannot take it back. We can stop renewing it, but we cannot stop the version that is already in your possession from working until its expiry.

A refund in that situation would mean returning your money while you keep an operational copy of the software, which is not a workable policy.

For the same reason, we offer a 7-day free trial before any purchase. The trial unlocks the full Pro feature set on your machine with no payment instrument required. If Vulkro is going to be a fit for your codebase, you will know inside 7 days.

If you are unhappy​

We would rather have a fair conversation than a frustrated customer. If something is not working for you, whether that's the product, a billing mistake, a missing detector, or anything else, email [email protected] with the details and we will respond personally. We do not tier our response queue by plan; everyone gets the same attention. We will do what we reasonably can to resolve it, including but not limited to:

  • Fixing the underlying issue if it is a real bug
  • Issuing a fresh license bound to a different machine if your hardware changed
  • Crediting unused time toward a different plan
  • In exceptional circumstances, considering a partial or full goodwill refund at our sole discretion

We make no promises about which path we will take. We make this promise: we will read your email, take it seriously, and write back with a real response from a real person.

Nothing to "cancel"​

All four plans are one-time purchases. When your license expires, nothing recurs and nothing renews. The CLI tells you the license lapsed; new CVE bundles and major detector updates are gated until you buy another. Buy a fresh one-time license whenever you're ready, or don't, and keep using the version of Vulkro you have. There is no subscription portal because there is no subscription.

Chargebacks​

If you initiate a chargeback through your payment provider without first contacting us, we reserve the right to revoke the customer relationship (no future licenses, no future support), in addition to whatever your card network decides about the disputed amount. Please email us first. It is faster and usually friendlier.
