Privacy Policy
KamiSign ("we", "us") is an online e-signature service. This policy explains what we collect, why, and the choices you have.
1. Signing as a guest
If you sign a PDF without an account, the file stays in your browser. We do not receive it unless you choose to send it for signature or save it to a vault.
2. What we collect
- Account details: your name and email address, and your Google profile name and email if you use Google sign-in.
- Documents: PDFs you send for signature or save to your vault, the fields placed on them, and the signed copies with their Certificate of Completion.
- Signer details: name, email address, signature image, typed legal name, the time they agreed to sign electronically, their IP address, and basic device and browser information.
- Email verification: if a sender requires it, we record that the signer verified their email address and when.
- Contacts and drafts: client contacts you add, and drafts you save while editing.
- Support chat: messages you type into the help chat.
- Technical data: basic request logs kept by our hosting providers for security and reliability.
3. Accounts created for signers
When a sender requires email verification, a signer proves they control their email address by entering a code we email them, or by signing in with Google. This creates a KamiSign account for that email address. You can ask us to delete it at any time.
4. How we use it
- To deliver, collect and seal signed documents, and to email signing requests, reminders and completed copies.
- To build the Certificate of Completion, which records who signed, when, and a SHA-256 fingerprint of the document.
- To prevent abuse, enforce limits and keep the service secure.
We do not sell your personal information, and we do not use your documents for advertising.
5. Who we share it with
- Other parties to your document: senders and signers see the document, each other's names and emails, and the completed copy and certificate.
- Service providers that run KamiSign for us: Cloudflare (hosting and storage), Supabase (accounts and database), Resend (email delivery) and Google (sign-in, if you choose it).
- Anthropic, which powers the support chat. Chat messages are sent to it to generate replies. Do not put passwords, codes or document contents in the chat.
- Legal requests: where the law requires it.
6. How long we keep it
- Pending envelopes are held for up to 30 days, then expire.
- Sealed documents saved to a vault are kept until you delete them or ask us to.
- Account and contact data is kept while your account is active.
7. Security
Data is sent over HTTPS. Signing links are personal and secret, and senders can require signers to verify their email first. No system is perfectly secure, so we cannot guarantee absolute security.
8. Your choices
You can ask to access, correct or delete your personal information, including your account and saved documents, by emailing us. Deleting a document does not remove copies already sent to other parties by email.
9. Children
KamiSign is not intended for anyone under 18.
10. Changes
We may update this policy. The date at the top shows the latest version.
