Last updated: April 1, 2026
This Privacy Policy explains how ctx engineering, inc. (ctx, we, us) handles information in connection with the ctx public beta, including the public documentation site and the ctx desktop app.
Scope
This policy applies to:
- the public ctx documentation site
- the ctx desktop app and related beta services we operate directly
- support, issue reporting, and other direct communications with us
This policy does not control third-party services that you choose to connect to ctx, such as model providers, code hosting platforms, or your own infrastructure providers. Those services have their own terms and privacy practices.
Launch status
At launch:
- ctx does not require a ctx account
- ctx does not offer paid plans or billing
- ctx does not provide managed mobile access or managed tunnel services
If that changes later, we may update this policy.
Information we collect
We may collect the following categories of information:
- contact information and message contents when you email us or contact support
- issue reports, screenshots, logs, and other materials you choose to send us
- basic docs-site usage analytics from the documentation infrastructure we use to operate the public site
- product telemetry from the ctx app when telemetry is enabled
- technical information needed to operate and secure the site or app, such as device, operating system, app version, crash, diagnostic, and similar usage information
We do not require a ctx account for launch, so we are not collecting account profile information for normal product use at this time.
How ctx works with your code and prompts
ctx is designed to be local-first for normal desktop use. In general:
- your repositories and task state stay on the machine or remote host you control
- prompts, context, and model outputs may be sent to the provider or router you connect to use agent features
- telemetry and docs-site analytics are separate from model-provider traffic
If you connect a third-party model provider or router, that provider may receive prompts, repository context, outputs, and related metadata needed to provide its service.
How we use information
We use information we collect to:
- operate, maintain, and improve ctx and the docs site
- understand product and docs usage at a high level
- diagnose bugs, crashes, and performance problems
- respond to support, privacy, and security requests
- protect the security, integrity, and availability of ctx and our users
- comply with legal obligations and enforce our terms
Telemetry and analytics
The ctx app may send product telemetry by default during the public beta. Where telemetry controls are available, you can opt out through product settings.
Our public docs site may also collect basic usage analytics through the documentation platform and site infrastructure we use to operate the site.
Telemetry and analytics help us understand usage, reliability, and adoption, but they are not the same as the prompts and outputs sent through the providers you connect.
When we share information
We may share information:
- with service providers and infrastructure vendors that help us operate ctx, the docs site, support, and analytics
- with model providers or routers you choose to connect when agent features send them prompts, context, or outputs
- when required by law, legal process, or a valid government request
- to protect the rights, safety, and security of ctx, our users, or others
- in connection with a merger, acquisition, financing, reorganization, or sale of assets
We do not sell personal information in the ordinary meaning of that term.
Retention
We retain information for as long as reasonably necessary for the purposes described in this policy, including to operate the beta, investigate issues, maintain security, comply with legal obligations, and resolve disputes.
Retention periods may vary depending on the type of information, how it was collected, and whether we need it for security, debugging, or legal reasons.
Your choices
You can:
- choose what information you send us in support requests and issue reports
- use product telemetry controls where available
- avoid including unnecessary secrets, credentials, or proprietary code in support messages
Because the product is local-first and does not require a ctx account at launch, many repository and workspace decisions remain under your control on the systems you manage.
Privacy rights
Depending on where you live, you may have legal rights regarding personal information, including rights to request access, correction, deletion, or additional information.
To make a privacy request, email [email protected]. We will review and respond as required by applicable law.
Children
ctx is not directed to children under 13, and we do not knowingly collect personal information from children under 13 through the public beta.
Changes to this policy
We may update this Privacy Policy from time to time. We will post the updated version on this page and update the Last updated date above.
