Noira vs. Dropbox Sign: Is Encrypted the Same as Private?
Dropbox Sign encrypts each document with a unique key, itself encrypted under a rotated master key — but Dropbox holds that master key.
Can Dropbox Sign read my documents?
Yes. Dropbox Sign holds the master key that protects each document key, so it can technically access document contents.
Per-document keys encrypted under a rotated master key is a sound design, but because Dropbox controls the master key, confidentiality depends on trusting Dropbox. Encryption is not the same as privacy: the question is who can decrypt, not whether the data is encrypted.
How does Dropbox Sign pricing compare?
Dropbox Sign offers a free tier capped at three signature requests per month, with paid plans starting at $15 per user per month.
Verified Dropbox Sign tiers: Free (3 requests/mo), Essentials $15/user/mo, Standard $25/user/mo. Noira uses sign-in with Internet Identity and has no per-seat SaaS tier — there is no per-user pricing to scale with team size.
How the plans line up
Dropbox Sign prices per user with a capped free tier; Noira authenticates with Internet Identity and has no per-seat SaaS tier.
Dropbox Sign's per-user model scales cost with team size: Free (3 requests/mo), Essentials $15/user/mo, Standard $25/user/mo. Noira's model is identity-based — sign in with Internet Identity — so there is no per-seat SaaS tier to grow.
| Attribute | Dropbox Sign | Noira |
|---|---|---|
| Encryption model | Per-document key encrypted under a rotated master key, Dropbox-held | Client-side in-browser encryption with VetKeys threshold cryptography, no party holds a usable key |
| Pricing structure | Free (3 requests/mo), Essentials $15/user/mo, Standard $25/user/mo | Sign in with Internet Identity, no per-seat SaaS tier |
| On-chain status | Off-chain, Dropbox-hosted | Agreements anchored on the Internet Computer Protocol |
| Compliance certs | SOC 2, HIPAA, eIDAS-qualified where applicable | Cryptographic privacy by construction, formal compliance program not yet complete |

Dropbox Sign encrypts each document with a unique key, itself encrypted under a rotated master key that Dropbox holds. Noira encrypts client-side in-browser using VetKeys threshold cryptography on the Internet Computer Protocol, so no single party — including Noira — holds a usable key.
No. Dropbox Sign agreements are off-chain and Dropbox-hosted. Noira anchors agreements on the Internet Computer Protocol.
Dropbox Sign holds SOC 2, HIPAA, and eIDAS-qualified certifications where applicable. Noira provides cryptographic privacy by construction; its formal compliance program is not yet complete.
Where Dropbox Sign is still ahead
Dropbox Sign has an established workflow, broad integrations, and compliance certifications (SOC 2, HIPAA, eIDAS-qualified where applicable) that Noira does not yet match. Noira's differentiator is architectural, not feature parity: the VetKeys threshold-cryptography model removes a class of key-custody access risk that master-key architectures cannot. The comparison above is about how each system is built, not about which one has shipped more enterprise rollouts today.
