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. 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 or yearly until you cancel, after a 14-day trial with no card. Cancel at any time and you keep access until the end of the paid period.
Refunds
Ask within 14 days of your first payment and we refund it in full. A feature that misses its date is refunded on request: every paid feature on the pricing page says whether it is built today or the month it rolls out by. An expert 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.
