← All productsSignDroid
Get documents signed — on your infrastructure, under your brand, with evidence that holds up.
Upload a PDF, place the fields, and send tokenised links. Signees sign in the browser with no account, behind an emailed access code and an identity check. What comes back is a completed document carrying an addendum, a consent record, a disclaimer, a full audit certificate, trusted timestamps and a cryptographic seal over the exact archived bytes.

The problem
Signing is solved. Signing on your own terms is not.
Established signature services work well and cost per envelope, per user, per year — and every contract you send passes through infrastructure you do not control, in a jurisdiction you did not choose, under a brand that is not yours. For a firm whose documents are commercially sensitive, both of those are the problem rather than a detail.
01
Per-envelope pricing
A cost that scales with the thing you want more of, and a renewal conversation every year.
02
Someone else's tenancy
Contracts, mandates and personnel files processed and stored outside your control.
03
Someone else's brand
Your client signs on a page carrying a vendor's name, not yours.
04
Thin evidence
A certificate of completion that proves far less than a dispute will ask of it.
The solution
Your servers, your domain, your logo — and a deeper evidence file than the envelope price buys.
01
White-label to the domain
Branding resolves from the host the visitor arrived on — a signee on your client's own domain sees your client's logo, colours and name, on the login page and the signing page alike, before anyone has logged in.
02
Evidence, not just a tick
Every completed document carries a generated addendum, consent, disclaimer and audit pages, embedded trusted timestamps, per-signee snapshots, and a detached cryptographic seal over the final bytes.
03
Every entity, its own identity
Tenants, organisations, per-tenant branding, per-organisation mail providers and payment credentials — so every company, brand or department in your group signs under its own name, from one installation.
Capabilities
01Document preparation & signing
- Upload one PDF, or merge several into one document in a chosen order.
- A visual field editor: click to place, drag to move, resize by handle, with zoom and a thumbnail rail.
- Five field types — signature, text, date, checkbox and dropdown — each with label, instructions, validation and length limits.
- No account required: a single tokenised link is the whole entry path.
- A layered, fully audited gate: emailed six-digit access code, identity check, consent and disclaimer acknowledgement.
- Sign by drawing on canvas or typing a name, with sequential or all-at-once signing order, and a ‘refuse to sign’ option that returns the document to the sender.
- Templates with pre-placed fields and abstract signee roles, translatable per locale.
02Evidence & identity
- Every completed document carries generated addendum, consent, disclaimer and audit-certificate pages, produced in the document's own language.
- The audit certificate lists the history timeline, access log, signature details, entered field data and the verbatim consent wording.
- RFC 3161 trusted timestamps taken per signature and per document, embedded into the file as attachments.
- Per-signee snapshots capture the chain of custody as the document passes between parties.
- A detached 4096-bit cryptographic seal over the exact archived bytes, with the organisation's public key downloadable for verification.
- An optional stricter mode adds an out-of-band SMS one-time passcode — six digits, ten-minute life, hashed storage, lockout after five attempts, and a per-signee key binding signee, document, field and time.
03White-label & multilingual
- Three-level tenancy — tenant, organisation, user — with organisation types for customer, internal, partner and trial.
- Custom domains resolve branding — logo, colours and name — before login and on the signing page itself.
- The platform's own name is replaced end to end; a signee never sees the vendor behind it.
- Three shipped languages (English, French, Dutch) at over 3,000 keys each, with a translation console and built-in machine translation.
- Audit certificates, consent pages and emails are all generated in the document's own language.
04Communications & administration
- Six notification types with independent per-organisation switches, plus reminders on demand or in bulk.
- Five mail providers per organisation — Microsoft Graph, Gmail, Zoho, plain SMTP and Outboundly — with encrypted credentials and automatic token refresh.
- Fifty-seven audit action types recording actor, address, agent and before-and-after values, plus a separate per-signature forensic record.
- Document lifecycle controls: archive, cancel with reason, copy, and deletion blocked once signing is under way.
- An hourly expiry sweep and a nightly housekeeping run that purges expired tokens and reconciles orphaned files.
- A log viewer with live tail, download and runtime log-level changes, plus a memory console.
- Per-user, per-table sort preferences and a full dark theme.

LicenceLicensed per installation, on your own annual turnover, ex VAT — never per envelope. Pricing is marginal, like income tax: each slice of turnover is charged at its own rate, with a €900 minimum and any yearly increase capped at 25%. Every tranche includes unlimited users, projects and organisations in one tenant, self-hosting, and support that rises with the tranche.
