Is Notion AI data secure?
As of 2026-07, Notion AI is covered by SOC 2 Type 2 and ISO 27001, encrypts data in transit with TLS 1.2+, and does not use your content to train AI models. AI providers retain data 30 days or fewer (zero retention on Enterprise), customer data is kept segregated, and embeddings are deleted within 60 days.
Why — the first-principles explanation
Data security for an AI feature has three parts: how data moves, who can touch it, and how long anyone keeps it. Notion AI addresses all three, and the guarantees are meaningful because they are backed by independent audits, not just marketing.
For movement, data sent to AI providers travels encrypted with TLS 1.2 or higher, so it cannot be read in transit. For access and reuse, Notion contractually blocks its providers (OpenAI, Anthropic) from training on your content, and it keeps each customer's data segregated rather than mixed together during processing. The credibility here comes from SOC 2 Type 2 and ISO 27001, which are external certifications that check a company's controls actually work over time, plus HIPAA-enabling zero-retention APIs for regulated data.
For retention, providers hold your data 30 days or fewer on regular plans and zero days on Enterprise, and search embeddings are deleted within 60 days of you deleting the page. The honest caveat is that no cloud tool is risk-free: your own account security (strong passwords, two-factor login) and who you share pages with still matter. But on the vendor's side, Notion AI meets the security bar businesses expect.
An example that makes it click
Think of sending a package through a courier. Security means three things: the box is sealed so nobody peeks (encryption), the courier signs a rule that they won't copy what's inside (no training, segregation), and they promise to shred the shipping label soon after delivery (retention limits). On top of that, an outside inspector audits the courier every year to confirm they really follow the rules — that's SOC 2 and ISO 27001.
Notion AI is that audited courier. Your data is sealed, not copied for others, and cleared out on a schedule. But you still have to lock your own front door, meaning your account password.
Key facts
- Notion AI is included in Notion's SOC 2 Type 2 report and ISO 27001 certification.
- Data sent to AI subprocessors is encrypted in transit with TLS 1.2 or greater.
- Customer data is not used to train AI models, and each customer's data is kept segregated during processing.
- AI providers retain data 30 days or fewer on non-Enterprise plans; Enterprise has zero data retention.
- Search embeddings are deleted within 60 days of deleting the related page or workspace; zero-retention APIs enable HIPAA compliance.

Is your data secure with Notion AI? On the vendor's side, yes — and it comes down to three things. One, movement: data sent to the AI providers is encrypted in transit with TLS 1.2 or higher, so it can't be read along the way. Two, access: Notion contractually blocks providers like OpenAI and Anthropic from training on your content, and it keeps each customer's data separated during processing. Three, retention: providers hold your data thirty days or less, and Enterprise gets zero retention. Backing all this up are independent audits — SOC 2 Type 2 and ISO 27001 — plus HIPAA-enabling zero-retention APIs. The one part that's on you: use a strong password and two-factor login, and be careful who you share pages with.
