Encrypted at rest
Documents, signatures, field values, names, email addresses and audit details are encrypted with AES-256-GCM before they're stored. Each document has its own keys. -
Encrypted in transit
Every connection to SignThis uses TLS (HTTPS). -
Frozen when sent
The PDF and its fields are frozen when you send. A change means a new version that everyone signs again. -
Tamper-evident audit trail
Every step is written to a SHA-256 hash-chained audit trail, so a removed or edited entry shows up. -
Sealed and timestamped
Completed PDFs are sealed with a digital signature and an RFC 3161 trusted timestamp. -
Verify without uploading

Questions, answered
Straight answers about signing, the free plan and billing.
Still have a question? support@signthis.pro
Do the people I send to need an account?
No. Signers open their personal email link, review the document, and sign in their browser. They can use a phone, tablet, or computer. Only the sender needs an account.
Can I use my own signature?
Yes. Draw your signature, choose a handwriting style for your name, or capture a signature from paper. You can also use your phone as a signature pad for your computer.
Are electronic signatures legally binding?
Electronic signatures can be legally binding in many jurisdictions, but the rules depend on the document, the parties, and local law. SignThis records consent and an audit trail; it does not provide a qualified electronic signature, notarization, identity verification, or legal advice. Check the requirements for your document before sending.
What happens after everyone signs?
We prepare a sealed PDF and an audit certificate, then email copies to the participants. Keep your downloaded copies in your own records. The digital seal helps detect changes, and our verification page can check a completed file's fingerprint without uploading the file.
How does the free plan work?
You can send up to 5 documents during your first 40 days, whichever limit comes first, with no payment card required. That allowance is shared across the workspaces you create. Afterward, choose a paid plan to keep sending. Signing documents sent to you is free.
Can I cancel my subscription?
Individual plans are billed monthly; cancelling stops renewal after the current paid month. Business plans have a 12-month commitment paid in monthly installments, with cancellation taking effect at the end of that commitment. Business seat minimums apply. Manage renewal from Plan and billing; statutory cancellation and refund rights remain available.
