Privacy

Last updated: September 2026

Documentation site

Blackthorn Interstellar publishes this static site. It has no accounts or forms. It loads OpenAI's oaiq advertising pixel from bzrcdn.openai.com. The pixel records page views and standard browser request data such as your IP address, user agent, and referring page. On pages with install commands, it also records copy and selection events. We use the data to measure advertising and documentation traffic.

OpenAI processes this data under its privacy policy. We do not sell it or combine it with other information about you.

You can block the pixel with a tracker blocker. Browser third-party-cookie and privacy settings also limit what it can record.

California residents: you may opt out of sharing your personal information for cross-context behavioral advertising by emailing privacy@pypiron.com. We will honor the request.

Package server

pypiron has no product telemetry, account service, or update check. It does not send package names, download counts, credentials, or configuration to pypiron.com.

The server makes network requests required by the features you configure:

• By default, it polls the public OSV PyPI advisory feed for malware and vulnerability data. Set --advisory-feed "" to disable the feed and the organization audit.
• With --proxy-upstream, it requests public package listings and files from that upstream when clients ask for them.
• Object-storage deployments read and write the S3, GCS, Azure, or compatible endpoint you configure.
• On cloud VMs, pypiron may query the provider's instance metadata for credentials and its region.
• pypiron sync contacts its configured source and destination.

Access logs, download statistics, and package metadata stay in your server and storage. Your cloud provider, upstream package index, forward proxy, or network operator may retain its own request records under its own policy.
