SignNow
Cloud e-signature platform for sending, signing and tracking documents.
Operated by airSlate
Where your files are processed
Reported to upload your files
The vendor states that files are uploaded to their servers. We have not independently tested this.
The mobile app can sign and edit offline and sync when back online, but documents are uploaded to and stored on SignNow's servers for sending, tracking and web access.
What it does
SignNow, part of airSlate, is a cloud e-signature service. You upload a document, add fields, then send it to one or more signers by email, SMS, link or kiosk mode and track opens, signatures and audit history. It also fills forms, adds text and checkboxes, converts images to PDF and stores completed documents in the account. A documented REST API with SDKs is available, and pricing is by signature invites rather than per seat.
Best for: Organisations that need legally binding e-signatures with audit trails, shared workspaces and API integration, and that accept US-hosted cloud processing.
Worth knowing: A paid cloud service — only a free trial was verified, not a permanent free tier. Extra signature invites are billed on top of the included allowance, and the vendor's data processing addendum states that EU personal data is transferred to and processed in the United States. Bulk signature invites are documented: recipients receive separate requests rather than signing one shared document, and plan and role restrictions apply. Public sources conflict on the allowance, with a September 2026 article supporting invite-based pricing while another current help article still describes per-user invite allowances, so the conflict is recorded rather than resolved and the applicable checkout or contract is the thing to verify. The capability landing page's comparison table is not treated as free-plan evidence. A free trial is the verified scope, and the absence of a permanent free plan is not proved by that alone. Fields and forms are preparation rather than general PDF editing, and legal validity is qualified by workflow and jurisdiction rather than guaranteed for every agreement.
Details, and where each comes from
Vendor statements, our own reading of their pages, and the things nobody has established yet, each answered separately. Where we have not confirmed something it says so rather than guessing, and a row nobody has established is greyed out.

What the redaction verdict rests on
From the vendor's own documentation, read 22 September 2026. Not tested by us.
What that does not establish: The vendor’s own site was read on 22 September 2026 and contains no mention of redaction, sanitisation, blackout or whiteout. Absence from a vendor’s own material is not proof that a feature does not exist — it may be undocumented, or on a page the reading did not reach — but for a NEGATIVE claim it is the strongest evidence available, and it is weaker than a positive quote. Recorded as such rather than presented as certainty.
What the vendor says
Claims are labelled rather than repeated as fact. Where we have checked something ourselves, it says so and shows when. Checked means we read the vendor's own page and it says what we recorded — not that we tested the behaviour, unless the note says we did.

“Every paid SignNow plan comes with Unlimited Free Seats: add one person or one hundred, and your subscription cost doesn't change because of it.”
Checked by us — the source says this Read 22 September 2026
Confirmed verbatim: the sentence is the article's opening line. The next sentence gives the pricing logic behind it and is worth carrying, because it names what the customer is actually billed for: "You pay for the signatures you actually collect, not for the number of people who happen to have a login." So seats are unlimited on paid plans and usage is metered by signature volume instead — a genuinely different model from the per-seat pricing recorded for Syncfusion and Foxit in adjacent tiers, and the kind of difference a buyer comparing tools would want stated plainly. The page does not give the signature price itself. Recorded as the vendor's description; no account was created and no control was run.

“SignNow is used by over 6 million people worldwide to sign, send, and manage documents — wherever they are, on any device.”

Confirmed verbatim: the sentence appears unaltered in the app's description, immediately after "Start your free 7-day trial — no credit card required." Worth noting what kind of source this is: the claim's figures come from an app store listing controlled by the vendor, not from an independent register, and Apple does not verify user counts. The same description also carries the trial terms, which is the more actionable part. This is the second SignNow claim in the index, after the unlimited-seats one, and the two come from a help centre article and an app store listing respectively.

- real change: the App Store listing text differs by 34 characters. Store listings change with every release, so this source is unstable by nature.
