To access, review, and sign contracts on Noira, you need:

• ▸A modern web browser (current Chrome, Firefox, Safari, or Edge) with JavaScript enabled.
• ▸An Internet Identity anchor, used to authenticate and bind your signature to your principal.
• ▸A PDF reader for viewing and storing downloaded copies of your signed contracts.
• ▸A reliable internet connection capable of reaching the Internet Computer network.

Noira does not require any proprietary plugin, desktop application, or mobile app. All signing happens in the browser.

You may withdraw your consent to use electronic signatures for future contracts at any time by contacting Noira support at noiracontracts@gmail.com.

Withdrawing consent does not retroactively invalidate contracts you have already signed. Existing signed contracts remain on-chain and encrypted — they are immutable records of the agreement you entered into. Withdrawal only affects your ability to sign new contracts electronically through Noira going forward.

If you withdraw consent, you and your counterparty will need to execute future agreements by traditional paper means outside of Noira.

To obtain a paper copy, download the PDF from your contract and print it, or coordinate with the other party directly.

Noira is a zero-knowledge signing system — it does not hold a plaintext copy of your contract and cannot produce one for printing. The PDF available from the contract detail view is the authoritative portable copy; printing it or arranging a paper copy with your counterparty is the only path.

Noira is a zero-knowledge signing system. Contracts are encrypted on the client before they ever reach the chain, and only the parties hold the keys to decrypt them.

Noira cannot decrypt or produce plaintext to a court — only the contracting parties can. This is the zero-knowledge line, by design: encryption and decryption happen entirely client-side, and the backend only ever stores ciphertext and a hash of the encrypted record.

Noira cannot produce the plaintext of a contract to a court, a regulator, or any third party — including in response to a subpoena. Only the parties who hold the decryption keys can decrypt.

Noira is ESIGN-aligned for sophisticated B2B parties who accept zero-knowledge tradeoffs. It is not a consumer contracting tool. If you require a signing platform that can produce plaintext records on demand, Noira is not the right tool for your transaction.

Noira retains the encrypted record for 7 years. Parties should download their own copy.

Contracts are stored on-chain indefinitely — this is the current reality of on-chain storage on the Internet Computer. Noira does not currently offer a configurable purge of on-chain records after the retention window.

Deleting your Noira account removes your user profile but does not remove contracts you are a party to. Signed contracts persist on-chain because they are shared records between two or more parties.

The 7-year figure describes Noira's commitment to keeping the encrypted record retrievable for the parties; it does not imply deletion at year 7. Download your PDF.

Noira's zero-knowledge design means there is no backdoor. If a party loses both their downloaded PDF copy and their Internet Identity access, recovery is not possible.

Noira cannot decrypt the contract for you. Noira cannot reissue your Internet Identity. Noira cannot restore a lost PDF. If both are gone, the contract is gone for you.

This is stated plainly without softening. Protect your II anchor. Download your PDF. Store both somewhere you can recover them. Noira is not a custodian of your keys or your documents.

For any question about these disclosures, consent withdrawal, or the signing process, contact Noira support:

Support cannot decrypt your contracts, reissue your Internet Identity, or restore a lost PDF — but can help with everything else.
