Draft — under legal review. This policy will be finalized before HydraSign opens to the public.
Privacy Policy
Last updated: November 14, 2026
This policy explains how HydraSign LLC ("HydraSign," "we") collects, uses and shares information when you use the HydraSign service.
Information we collect
- Account information — name, email, company name, password (stored only as a secure hash), and team members you invite.
- Documents — files you upload and the information entered into them during signing.
- Signer information — names, email addresses and phone numbers of people you send documents to, and, when they view or sign, their IP address, device/browser details, times of each action, and the signature they adopt. This is recorded in the audit trail and Certificate of Completion.
- Billing information — plan, billing email and the last four digits and expiry of your card. Full card numbers are collected and stored by our payment processor, not by us.
- Usage information — basic logs such as sign-in times and actions taken in the Service, used for security and support.
How we use information
To provide the Service (sending, signing, storing and delivering documents), to create audit trails that support the validity of signatures, to bill you, to keep the Service secure and prevent fraud, to provide support, and to send service messages. We do not sell personal information and we do not use your documents for advertising.
Who we share it with
- Other parties to your documents — the people you send a document to can see it and, once complete, the Certificate of Completion.
- Service providers who help us run the Service under contract: cloud hosting and storage, email delivery, text-message delivery, and payment processing.
- Legal — when required by law, subpoena or court order, or to protect rights and safety.
- Business transfers — if HydraSign is sold or merged, information may transfer to the new owner under this policy.
Your documents belong to you
Account owners control the documents in their account. If you signed a document someone else sent, contact the sender for copies or changes; we process that information on the sender's behalf.
Retention
We keep account data and documents while the account is open. After an account closes we may delete documents after 90 days, except where we must keep records longer by law. Audit records may be kept for as long as the related document exists.
Security
Data is encrypted in transit (HTTPS) and stored with providers that encrypt data at rest. Signing links are unique and can be protected with access codes. No system is perfectly secure; tell us right away if you suspect unauthorized access.
Your choices and rights
You can update account information in Settings and download your documents at any time. You may ask us to access, correct or delete your personal information by contacting us. Depending on where you live (for example Washington or California), you may have additional rights; we will respond as the law requires. Text-message recipients can reply STOP to opt out.
Children
HydraSign is for businesses and adults. We do not knowingly collect information from children under 13.
Changes
We will post changes here and notify account owners of material changes.
