Yes. SignNinja’s standard electronic signatures are built around the same principles recognized under the U.S. ESIGN Act and UETA — verified signer identity, recorded intent to sign, and a tamper-evident record of the transaction. Whether a specific document type requires additional formality varies by jurisdiction and use case, so for anything high-stakes we’d always recommend checking with your own legal counsel.

Not yet. A standard SignNinja signature is an electronic signature usable for everyday business agreements in both the U.S. and India — it is not the same thing as India’s Certifying Authority-backed eSign, which relies on Aadhaar and a government-authorized provider. A dedicated integration with an authorized eSign provider, for the specific transactions that legally require it, is on our roadmap.

No. A recipient opens the email link, confirms who they are, and signs directly in the browser — no SignNinja account, no software download, no app.

It’s free forever — no credit card, no time limit, and nothing to cancel. The free plan includes 3 sign requests per month. If you need more in a given month, Pro and Unlimited plans remove that cap.

Every signer and the sender automatically receive the final, sealed document by email. The sender can also view and download it any time from their SignNinja dashboard, along with the full audit trail for that sign request.

Documents and signing data are encrypted, isolated per organization, and access-controlled throughout the signing process. Every audit event is hash-chained to the one before it, so the history of a transaction shows if any part of the record was altered after the fact.
