# Privacy Policy

Last updated: August 27, 2026

This website is primarily a public informational site and does not require an account to browse. Individual services may collect limited operational information needed to provide, secure, measure, and troubleshoot the service; current service documentation describes service-specific behavior.

## Random Choice

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

## Temporary File Relay

Temporary File Relay stores uploaded files in Cloudflare R2. 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 declared byte size and content type before publication. Do not upload passwords, private keys, secrets, personal records, regulated data, or other sensitive material.

## Infrastructure and contact

Preflight Stack relies on third-party infrastructure, including Cloudflare and Coinbase x402 infrastructure where applicable. Questions can be sent to support@preflightstack.com.
