Terms and refunds

Last updated: 2026-11-06.

The tool

The open source tool is licensed under MIT. SIGSHIP uses pattern checks. A GO result is not a security audit and does not prove your app is safe. You stay responsible for your app.

Paid plans

Paid plans are not on sale yet. When they open: self-hosted Pro and Business are one-time purchases that include a year of new checks, and you keep using what you bought after that year. Cloud plans renew monthly until you cancel. Cancel at any time and you keep access until the end of the paid month.

Refunds

Ask within 14 days of your first payment and we refund it in full. A pilot review can be refunded in full until work starts.

Who you are dealing with

Polar is the merchant of record for payments. The service is provided by Zoof04 Inc. Email support@sigship.dev.
