Legal
Terms
Last updated 10 November 2026
These terms apply when you buy or use Seaworthy, made by Dynamo Maritime Ltd ("we", "us"), a company registered in England and Wales, company number 17152743, registered office 82 James Carter Road, Mildenhall, England, IP28 7DE.
1. What these terms cover
Seaworthy is software you download and run on your own computers. These terms, our privacy policy, our refund policy and the licences together make up the agreement between you and us. If they conflict, the licences decide how you may use the software, and these terms decide everything else.
2. Buying a plan
Paid plans are sold through Polar Software, Inc. ("Polar"), our merchant of record. Polar is the seller on your receipt, takes payment, handles sales tax and VAT, and issues invoices; its terms apply to the payment itself. The price you pay is the one shown at checkout.
3. Subscriptions
- Plans are billed monthly or yearly, as you chose at checkout, and renew automatically until you cancel.
- You can cancel at any time with the link in your receipt email. Your plan keeps working until the end of the period you've paid for.
- If we change the price of your plan, we'll email you at least 30 days before your next renewal at the new price, so you can cancel first.
4. Your licence key
- Each key is for the customer who bought it, on no more machines at once than its plan allows: 2 for Pro, 10 for Agency.
- Keep your key private. Don't share or resell it.
- Using the key in your own CI pipelines is allowed and doesn't count towards the machine limit.
5. The free version
The free version of Seaworthy is provided under the Functional Source License, with no charge and no support commitment. These terms apply to it too, apart from the sections on payment and subscriptions.
6. Using Seaworthy responsibly
- Only scan code you own or have permission to scan.
- Don't try to get around the licence check or a plan's limits.
- Don't use Seaworthy to build or offer a competing product. The licences say more about this.
7. No guarantee
Seaworthy produces automated scan results. It is an aid, not an assurance: it is not a security certification or a guarantee, and no tool finds every problem. A clean scan does not mean your app is secure, and you remain responsible for the security of what you build and ship.
8. Our liability to you
Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud, or for anything else that the law does not allow us to limit or exclude.
If you use Seaworthy for business, we are not liable for loss of profits, revenue, business, data or goodwill, or for any indirect or consequential loss, and our total liability to you is limited to the amount you paid us in the 12 months before the claim.
If you are a consumer, we are responsible for loss or damage you suffer that is a foreseeable result of our breaking these terms or failing to use reasonable care and skill. We are not responsible for loss that was not foreseeable. If digital content we supply damages a device or other content of yours because we didn't use reasonable care and skill, we will repair the damage or pay you compensation. Your statutory rights are not affected.
9. Changes to Seaworthy and these terms
We improve Seaworthy over time: checks are added, refined and sometimes retired. We may update these terms; if a change materially affects a paid plan you have, we'll email you at least 30 days before it applies to you, and you can cancel and get a refund for the unused part of your subscription if you don't accept it.
10. Ending the agreement
You can stop using Seaworthy and cancel at any time. We may suspend or end your licence if you seriously or repeatedly break these terms, such as by sharing your key; we'll tell you why. If we stop offering a plan you've paid for, we'll refund the unused part.
11. Law and disputes
These terms are governed by the law of England and Wales. If you are a consumer living in Scotland or Northern Ireland, you can also bring proceedings in your local courts. Please contact us first: most problems are quicker to sort out by email.
