Website

This website is primarily a public informational site. It does not require a user account to browse.

Service requests

Individual Preflight Stack services may collect limited operational information needed to provide, secure, measure, and troubleshoot the service. Service-specific behavior is described in the applicable documentation.

Random Choice

Random Choice is designed so its pilot metrics do not store submitted choices or weights. It records privacy-minimized operational and commercial metrics used to understand service usage.

Temporary File Relay

Temporary File Relay stores uploaded files in Cloudflare R2 as part of its temporary handoff workflow. After successful completion, a file is reachable through an opaque capability URL until its documented seven-day expiry. The URL itself is the download capability: anyone who has it can retrieve the file while it remains valid.

The service validates the file's declared byte size and content type before publication. Do not upload passwords, private keys, secrets, personal records, regulated data, or other sensitive material. Temporary File Relay is designed for passive workflow artifacts, not private file sharing or permanent storage.

Third-party infrastructure

Preflight Stack relies on third-party infrastructure for hosting, storage, payments, networking, and public code hosting. This includes Cloudflare infrastructure and Coinbase x402 payment infrastructure where applicable. Those providers may process technical data under their own policies.
