# Security and privacy

Where ZeroWidth keeps your team's data, who can see the data, and how the data is deleted.

## Run ZeroWidth yourself, and nothing leaves your network.

### What ZeroWidth does differently

**Your own model, on your own servers**

Self-hosted ZeroWidth works with a model you run, so your team's words never leave your network.

**No retention, no training**

Hosted ZeroWidth sends text only to model hosts that keep nothing and never train on it.

**Staff access is granted and recorded**

An admin grants access for a limited time. We also look when we investigate a report of abuse. Every look is recorded.

## Data

**Hosted in the US**

On Google Cloud, in the United States.

**Encrypted**

In transit and at rest.

**Each team kept apart**

No team can see another team's data.

**Secrets removed first**

Passwords and keys in your text are removed before any AI model reads it.

## Access

**Sign-in by email link**

Each person signs in with a link sent to their own email address, and each AI tool they connect acts as them.

**Two-step sign-in**

Codes from an authenticator app, with recovery codes. An admin can require two-step sign-in for the whole team.

**Roles**

Owner, admin and member. [Members and sign-in](https://zerowidth.ai/docs/hosted/members)

**An audit log**

Every admin action is written to the team's audit log.

**Self-hosted stays local**

ZeroWidth answers only on its own computer until you open ZeroWidth to your network, and then every request needs a token.

## Retention and deletion

**Export**

An admin can download the team's data at any time. [Exporting your data](https://zerowidth.ai/docs/hosted/your-data#exporting-your-data)

**Deleting a team**

Deleted 7 days after the owner asks, and gone from backups 7 days after that. [Delete a team](https://zerowidth.ai/docs/hosted/delete-a-team)

## Subprocessors

**Google Cloud, OpenRouter, SendGrid and Stripe**

Hosting, AI model access, email and payments. [What each one does, and where](https://zerowidth.ai/subprocessors)
