Most e-signature tools confirm that someone with the right email clicked a link. Signometric confirms the actual human, on any kind of file.
Ordinary e-signatures
Signed… by an email address
Tied to an email account, whoever can open the inbox can sign.
Limited to PDFs and a handful of document formats.
No real proof the intended person was ever there.
Disputes come down to “it was sent to their address.”
Signometric
Signed by a verified person
Biometric proof that the real person signed, not just their email.
Any digital content, contracts, images, designs, data, code.
Tamper-evident, change anything after signing and the proof breaks.
Holds up later, proof anyone can trust, long after signing.
How it works
Signing you can actually stand behind
Create a Seal, collect signatures verified to real people, and prove it any time, in three simple steps.
One Seal, many roles. Each signer is bound to the document by their own face; anyone can later confirm a signature with just a public key, no account, and nothing to breach.
STEP 01
Create a Seal
Upload your document into a Seal, then distribute it to everyone who needs to sign. Any digital file works, not just PDFs.
STEP 02
Recipients sign
Each recipient signs with their own biometrics, verified as the real person, right on their own device. No shared logins, no impersonation.
STEP 03
Verify on demand
Open and verify the sealed document any time, with proof of exactly who signed and precisely what they agreed to.
From draft to lasting proof. A Seal runs from draft to completed, then stays verifiable for good, or ends early in red: declined by a signer, revoked by the sender, or expired past its deadline.
Use cases
Wherever a signature has to mean something
Anything you'd send through a signing tool today, made trustworthy and tied to a real person.
Contracts & agreements
Know the right person agreed to the exact terms they saw, not a copy quietly edited after the fact.
Board & approval sign-off
Ask several approvers to each sign as themselves before anything goes through. No shared logins, no impersonation.
Confidential delivery
Send sensitive documents that only the intended person can open, verified by them, not just guarded by a password.
Consent & disclosures
Capture a clear “I agree” tied to exactly what was shown, trustworthy and disputeproof years later.
Multi-party agreements
Deals that only count once every party has genuinely signed as themselves, no one gets ahead of the rest.
Audit & compliance
Every signature ties back to a real, verified person, clean, defensible records, with no biometrics ever stored.

Pricing
Plans that scale with how you sign
Simple plans, no surprises. Every plan is measured in face seals a month, where a face seal is one Seal you send for signing or one Verified Delivery — the two things that carry a verified identity. Ordinary document signing, where the signer draws or types their signature without an identity check, is unlimited on every plan and never counted. Signers are never counted either, so a contract going to eight people is still one face seal. Each plan also includes a number of seats, one for each person in your firm, and each of them signs in with their own face. Verifying a completed Seal is always included, so if a signature is ever questioned, you can prove who signed, at no extra cost.
Free trial
$0 /month
Two face seals, no card. Enough to send a real Seal, sign it with your
face and verify it afterwards, so you can judge the proof before you pay for it.
Your allowance is counted once per document, on the day you send it, and it resets at the start of each calendar month. Adding signers costs nothing, and neither does someone signing, opening or re-reading a document you have already sent. Verifying a completed Seal is always included on every plan. Most Seals are never challenged, but if a signature is ever disputed, you can prove exactly who signed and what they agreed to, any time, at no extra cost.

Questions the free tier can't answer
You don't need us to try it. Two face seals are free, no card, and that is enough to send a real Seal, sign it with your face and verify it afterwards. Get in touch when you need the things that sit outside that.
Effective 1 August 2026 · Last updated 1 August 2026
Signometric exists to prove who signed a document, and to do that with the least data possible. Privacy isn't a setting here; it's the design.
This policy explains what personal information we collect, how we use it, how we protect it, and your rights regarding your information. By using our website, applications, APIs, or services (collectively, the "Services"), you agree to this policy.
1. Face verification and biometric processing
Because signing with Signometric involves biometric processing, we set out here exactly what happens to a facial image.
How a signature is verified
Your device camera captures an image of your face at the moment of signing.
That image is transmitted over an encrypted connection to a third-party tokenisation service, which converts it into a face token.
The token is a value derived from the image. It is not an image, and it is not a photograph or a stored facial template.
The image itself exists only in server memory for the duration of that processing. It is not written to disk, not stored in any database, and not retained once the request completes.
What is retained, and what is not
To recognise a returning signer, we retain the derived face token, encrypted at rest. We do not retain the image it came from. We keep no photographs or video of a face, no face geometry maps, and no searchable library of faces, and neither we nor the organisation you are signing for can retrieve or view an image of your face.
Consent and alternatives
Face verification takes place only after you agree to it, and only for the purpose of proving who signed a document. You may withdraw consent at any time by contacting us or the organisation that sent you the document. If you would prefer not to sign with face verification, contact that organisation about an alternative.
Third-party tokenisation
The tokenisation service acts on our instructions and only for the purpose of producing a token during your verification. It is contractually restricted from retaining, reusing, or disclosing the image.
2. Information we collect
Information you provide: your account name, email address and phone number; for the clients you add, their name and phone number; encrypted or hashed passwords; account preferences; and information you voluntarily submit through forms, support requests or communications.
Documents and Seals: the documents you upload, the Seals you create, and the signatures applied to them. These are held so that a signature can be verified later, which is the purpose of the service.
Information generated through your use: user ID, account settings, authentication and signing events, timestamps, device identifiers where required for security, the IP address used during verification, security and error logs, and service usage necessary for operation. These records are used solely for security, reliability, fraud prevention, evidentiary integrity, and providing the Services.
Nothing is bought, enriched, or acquired from outside sources.
3. Information we do not collect
Government identification numbers
Financial information, unless specifically required by a separate service
Credit card information, unless processed through an integrated payment provider
Sensitive personal information unrelated to providing our Services
4. How we use your information
We use your information only to create and manage your account, verify signers, produce and validate Seals, provide requested Services, secure your account, respond to support requests, prevent fraud and abuse, maintain system and evidentiary integrity, comply with applicable laws, and communicate important service notices. We do not use your personal information for advertising or profiling.
5. We never sell or share your data
We do not sell, rent, trade, or share your personal information with anyone, for any purpose. No data brokers, no advertisers, no "partners." Ever. We do not build advertising profiles.
6. No tracking, no analytics
We run no third-party analytics, advertising, tracking pixels, or tracking cookies. We don't profile you and we don't follow you around the web. Nobody outside Signometric is watching what you do here.
Where we rely on third-party infrastructure providers, for example cloud hosting, biometric tokenisation, email delivery, or payment processing, those providers act only on our instructions and only to the extent necessary to provide the service.
7. Cookies
We use only essential cookies and similar technologies required for signing users in, maintaining authenticated sessions, security, preventing fraud, and remembering basic preferences. We do not use advertising or behavioural tracking cookies.
8. Password security
Your password is never stored in plain text. Passwords are securely hashed using industry-standard cryptographic methods before storage. Our staff cannot retrieve your password. If you forget it, it must be reset rather than recovered.
9. Data security
We take reasonable technical and organisational measures to protect your information, including encryption in transit (HTTPS/TLS), encryption of face tokens at rest, secure password hashing, restricted administrative access, firewalls, access controls, security monitoring, regular software updates, and backup procedures. Although we take appropriate measures, no system connected to the Internet can be guaranteed to be completely secure.
10. Data retention
We keep information only for as long as we need it to provide the service to you, meet legal obligations, resolve disputes, enforce our agreements, and maintain security records where appropriate.
Signed documents and their Seals are an exception worth stating plainly: because their purpose is to prove years later that a particular person signed a particular file, they are retained for as long as you keep your account or as long as the law requires, whichever is longer. Facial images are never retained at all, as described in section 1.
11. Your rights
Subject to applicable law, you may access, correct, or update your personal information; request deletion of your account or your personal information where legally permissible; request a copy of your information; withdraw consent where processing is based on consent; and object to certain processing activities. You can ask us to remove your data at any time and we will.
Deleting a face token means you will be treated as a new signer next time. It does not invalidate signatures already made, which remain verifiable as evidence of what happened at the time.
12. Account deletion
Following verification of your request, we will delete or anonymise your personal information unless we are required to retain certain records for legal, security, or regulatory purposes, or where a signed document must remain verifiable. Some backup copies may remain for a limited period before being permanently removed.
13. Children's privacy
Our Services are not directed to children under the age required by applicable law without appropriate parental or guardian consent. We do not knowingly collect personal information from children in violation of applicable law. If we become aware that such information has been collected, we will take reasonable steps to delete it.
14. International users
If you access our Services from outside the country where our servers are located, your information may be transferred to and processed in that country. By using our Services, you acknowledge this transfer where permitted by law.
15. Legal disclosure
We may disclose personal information only if required to comply with applicable law, respond to valid court orders or lawful government requests, protect our legal rights, prevent fraud or criminal activity, or protect the safety of our users or others. We do not voluntarily disclose personal information beyond these circumstances.
16. Changes to this policy
We may update this policy from time to time. Material changes will be communicated through our website or by email where appropriate. The updated policy becomes effective upon publication unless otherwise stated.
In simple terms
Your face is never stored. It becomes a token at the moment of signing and the image is discarded.
We store only what's needed to run the service and to keep your signatures provable.
We never sell your data or share it for advertising.
We use no third-party analytics or tracking.
You can ask for access, correction, or deletion at any time.
