Terms of Service

Last updated: November 14, 2026

These Terms of Service ("Terms") are an agreement between you and HydraSign LLC ("HydraSign," "we," "us"), a Washington limited liability company, and govern your use of the HydraSign electronic signature service, website and apps (the "Service"). By creating an account or using the Service you agree to these Terms. If you use the Service for a business, you agree on its behalf and confirm you have authority to do so.

1. The Service

HydraSign lets you upload documents, request electronic signatures, and store completed documents with an audit trail. People who sign documents you send ("Signers") may use the Service without an account; these Terms apply to them as far as they use it.

2. Accounts

You must give accurate information, keep your password secure, and are responsible for activity under your account and by users you invite. You must be at least 18 years old.

3. Subscriptions, trial and automatic renewal

• Free trial. New accounts get a free trial of the length shown at sign-up. No payment is required to start it.
• Plans and fees. Paid plans are billed monthly in advance, per active user, at the prices shown on our pricing page when you subscribe. Taxes may be added where required.
• Automatic renewal. Your subscription renews automatically each month and your card is charged on the renewal date until you cancel. You can cancel at any time in Plan & billing; cancellation takes effect at the end of the current paid period.
• Changes in users. Adding or removing users changes the amount of your next monthly charge.
• Refunds. Fees are non-refundable except where required by law. We do not issue partial-month refunds.
• Failed payments. If a payment fails we will notify you. If it isn't resolved within the grace period, sending may be paused until payment is made.
• Price changes. We will give at least 30 days' notice before changing the price of your plan.

Payments are processed by our payment processor. We do not store full card numbers.

4. Your documents and data

You own the documents and information you upload ("Your Content"). You give us permission to host, process, transmit and display Your Content only as needed to provide the Service. You are responsible for having the right to upload and share Your Content and for obtaining any consents required to send it to Signers.

5. Electronic signatures — your responsibilities

HydraSign provides tools that are designed to support electronic signatures under the U.S. ESIGN Act and state Uniform Electronic Transactions Acts. Whether a particular document can be signed electronically, and whether a signature is enforceable, depends on the document, the parties and the applicable law. Some documents (for example wills, certain court documents, and documents requiring notarization) may not be signable electronically. HydraSign does not provide legal advice, and you are responsible for deciding whether electronic signatures are appropriate for your documents.

6. Acceptable use

You may not use the Service to: break the law or violate others' rights; send fraudulent, deceptive or forged documents or signatures; send spam or unsolicited messages; upload malware; attempt to access other accounts or disrupt the Service; or resell the Service without our written permission. We may suspend accounts that violate these rules.

7. Text messages

If you send signing requests by text message, you confirm the recipient has agreed to receive texts from you about the document. Message and data rates may apply to recipients. Recipients can reply STOP to opt out.

8. Cancellation and data after you leave

After your subscription ends, you can still sign in to view and download completed documents for at least 90 days. After that, if your account is closed, we may delete Your Content. Download anything you need to keep.

9. Availability and changes

We work to keep the Service available but don't guarantee it will be uninterrupted. We may improve or change features; if we remove a major feature of a paid plan, we'll give notice.

10. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE EXTENT ALLOWED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT.

11. Limitation of liability

TO THE EXTENT ALLOWED BY LAW, NEITHER PARTY IS LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR LOST PROFITS. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE IS LIMITED TO THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM.

12. Indemnity

You will defend and indemnify HydraSign against claims arising from Your Content, your documents and transactions, or your violation of these Terms or the law.

13. Governing law

These Terms are governed by the laws of the State of Washington, without regard to conflict-of-law rules. Any dispute will be brought in the state or federal courts located in King County, Washington, and both parties consent to that venue.

14. Changes to these Terms

We may update these Terms. If a change is material we will notify you by email or in the Service at least 30 days before it takes effect. Continuing to use the Service after that means you accept the updated Terms.
