Legal
Terms of service
Last updated 3 October 2026
These terms cover your use of CoreSign, operated by Core Legacy Studios. They are written to be read, so they are shorter and plainer than they could be. Where something is a genuine limit on what we promise, it is stated rather than buried.
1. What CoreSign does
CoreSign carries documents for electronic signature, records the circumstances in which they were signed, and seals the completed result so it can be checked afterwards. That is the whole of the service.
We are not a party to any agreement you sign through CoreSign, and we are not a law firm. We do not give legal advice, and nothing in the product is a judgement about whether your document is valid, enforceable, or suitable for what you are using it for. Whether an electronic signature is appropriate for a particular document — some categories are excluded from electronic signing by law — is your responsibility to determine.
2. Signing does not require an account
If you have been asked to sign a document, you do not need an account and you are not charged. These terms still apply to your use of the signing page. Your rights as a signer sets out the parts most relevant to you.
3. Your account
- You are responsible for what happens under your account, and for keeping your credentials to yourself.
- You must give accurate information, and keep your email address current — it is how signing notices and account notices reach you.
- Accounts are for a single person or organisation, not shared.
- Tell us promptly if you believe your account is compromised.
4. What you may not do
- Send documents you have no right to send, or impersonate anyone when requesting a signature.
- Use CoreSign for fraud, phishing, or to obtain a signature by deception.
- Upload malware, or content that is unlawful where you or your recipients are.
- Attempt to interfere with the service, evade its access controls, or reach documents that are not yours. Good-faith security research is welcome and covered by the security page.
- Send bulk unsolicited email through the service.
We may suspend an account that appears to be doing any of these, and we will say why.
5. Your documents remain yours
You keep all rights in the documents you upload. You grant us permission to store, process, render and transmit them strictly to provide the service — delivering them to your signers, displaying them, producing the completed file, and sealing it. Nothing more.
We do not use your documents to train machine-learning models, and we do not use them for marketing.
You are responsible for having the right to send what you send, and for the accuracy of the signer details you supply.
6. Records and the seal
When signing completes we produce a signed document, a certificate of completion and a cryptographic seal binding them together. These are intended to serve as evidence of what was agreed.
Because their value depends entirely on their integrity, we will not alter a completed sealed record, and we cannot selectively remove parts of one at the request of a single party. If you need something corrected, void the document and issue a replacement.
Keep your own copies. Download the signed document and its certificate when signing completes. Do not rely on us as your only archive.
7. Payment, cancellation and refunds
How billing works
Paid plans are billed in advance through a third-party payment processor, either monthly or annually — whichever you choose at checkout. An annual plan is a billing interval, not a different plan: the monthly allowance and everything included are identical either way. Plans renew automatically for the same interval until you cancel or change it. We will give reasonable notice before changing a price, and a change never applies to an interval you have already paid for.
Paid plans can currently be bought with a billing address in the United States. Prices are shown without tax. The checkout shows any sales tax, with the total, before you pay.
Changing plan
You can change plan from your account’s plan page while your plan is paid up and not set to end.
Upgrading from Pro to Business takes effect immediately. We charge the card on file the difference between the two prices for the days left in your current billing period, plus any sales tax. You see that amount before you confirm, and it is the amount charged: if it has changed by the time you confirm, nothing is charged and you are shown the new amount. From your next renewal you are billed the Business price, on the same interval. If we cannot complete an upgrade after charging for it, we refund the charge in full and your plan does not change.
Moving from Business to Pro, or between monthly and annual billing, takes effect at your next renewal. Nothing is charged when you make the change, and you keep your current plan and everything included in it until then. You can undo it before the renewal by choosing Keep my plan. From the renewal date, the new plan’s price, allowance and features apply — moving to Pro ends webhooks, which are part of Business.
One change can wait at a time. To upgrade while another change is waiting, undo that change first. To upgrade and change your billing interval, upgrade first; the interval changes at the following renewal as a second change.
We email you to confirm each change.
Cancelling
You can cancel at any time, from your account’s Profile page or by writing to us. Cancellation stops the next renewal and takes effect at the end of the interval you have already paid for — you keep the plan until then rather than losing it immediately, and until then you can undo it by choosing Keep my plan. Export your completed documents and their certificates before the interval ends.
If a payment fails
If a renewal payment does not go through, we email you, and your plan stays active for 7 days after the renewal date; paying within that time keeps it. If it is still unpaid after 7 days, the subscription is cancelled, your account moves to the Free plan, and we email you again. You can subscribe again at any time.
Refunds
Charges are not refundable for an interval already begun, except where the law requires otherwise or where we have made a mistake — if you have been charged in error, or charged twice, tell us and we will put it right. Consumers in the UK, EU and some other jurisdictions have statutory cancellation rights that these terms do not affect.
If something is wrong, write to us before disputing the charge with your bank. We would rather put a genuine problem right directly than have it go through a dispute, which can take weeks to resolve.
8. Availability
We work to keep CoreSign available and will give notice of planned interruptions where we reasonably can. We do not offer a service level guarantee, and we are not going to publish an uptime figure we have not measured. The service is provided as it is.
9. Ending it
You may stop using CoreSign and close your account at any time. Export what you need first.
We may suspend or close an account for a material breach of these terms, or where we are required to. Except where the breach makes it impossible, we will tell you first and give you an opportunity to retrieve your documents.
10. Disclaimers and liability
CoreSign is provided without warranties of any kind to the fullest extent the law allows, including implied warranties of merchantability and fitness for a particular purpose. We do not warrant that the service will be uninterrupted or error-free.
To the extent permitted by law, our total liability arising out of or relating to the service is limited to the amount you paid us in the twelve months before the claim arose, and we are not liable for indirect, incidental or consequential loss, or for lost profits, lost business or lost data.
Nothing here limits liability that cannot lawfully be limited — including for fraud, or for death or personal injury caused by negligence.
11. Changes to these terms
We may update these terms. The date at the top changes when we do, and we will give account holders reasonable notice of a material change before it takes effect. Continuing to use CoreSign after that means you accept the change.
12. Governing law
These terms are governed by the laws of the State of North Carolina, without regard to its conflict-of-laws rules, and the courts there have exclusive jurisdiction over any dispute arising from them. Nothing in these terms deprives a consumer of the protection of mandatory provisions of the law of their own place of residence.
