Privacy Policy

Effective date: May 3, 2026

What this site is

cli.nylas.com is the documentation site for the Nylas CLI, an open-source command-line tool. It is operated by Nylas, Inc. This policy covers only this website, not the Nylas CLI tool itself or other Nylas services.

What we collect

This site uses Segment analytics to collect anonymous usage data including:

We do not collect names, email addresses, or any personally identifiable information through this site.

How we use it

We use analytics data to understand which guides and commands are most useful, identify broken pages, and improve the documentation. We do not sell or share this data with third parties beyond our analytics provider (Segment/Twilio).

Cookies

Segment may set a first-party cookie to distinguish unique visitors. No advertising or third-party tracking cookies are used.

Your rights

You can disable cookies in your browser settings. For data deletion requests or questions, contact us at support@nylas.com.

The Nylas CLI binary

This section covers the nylas command-line tool itself, distinct from this documentation site. The CLI is open source under the MIT license; the source of truth is github.com/nylas/cli.

No usage telemetry

The CLI does not phone home, report command usage, or send analytics to Nylas. Every network request the CLI makes is a direct call to the Nylas API in service of a command you ran — for example, nylas email list hits api.us.nylas.com (or the EU endpoint), and that is the only request it makes. There is no separate metrics or telemetry endpoint.

Where credentials live

API keys and OAuth grant tokens are stored locally in ~/.config/nylas/ in an encrypted credentials file. Tokens never leave your machine except as bearer credentials on the Nylas API requests they authenticate. Run nylas config reset to wipe local credentials.

What Nylas servers see

Nylas servers see only what you instruct the CLI to send: list/read/send email, calendar event reads and writes, contact reads and writes, webhook registrations, and grant lifecycle calls. The data these requests handle is the same data Nylas already processes for any application built on the Nylas API — the CLI just gives you a terminal interface to it. Nylas’s handling of API request data is governed by the Nylas Privacy Policy and Terms of Service.

Logging and audit

With --verbose the CLI emits request IDs and command metadata to stderr, but never raw API keys or message bodies. The optional AI-agent audit log (default path ~/.config/nylas/audit.log) stays on your machine; it is not transmitted to Nylas.
