Privacy Policy

1. Client-Side Static Execution

All physics calculations, DIY wizard inputs, and URL query state encodings (?v=1&r=...) execute strictly inside your web browser. RacketSpec Lab sets no cookies, runs no analytics or tracking scripts, and stores no user inputs on a database server.

However, racket setups saved in 'My Bag' are never transmitted to any external server and are stored strictly within your device's local browser storage (localStorage, key: racketspec.bag.v1). Clearing your browser site data removes them immediately.

🎙️ When measuring acoustic string tension, microphone audio data is processed entirely in local browser memory and immediately discarded after frequency (Hz) analysis. It is never recorded or transmitted to any external server.

2. Static Hosting & External Links

This site is served as static HTML/CSS/JS via Cloudflare Pages, which may process standard edge HTTP request metadata (such as IP address and user-agent) for network delivery and DDoS mitigation. If privacy-preserving web analytics or affiliate disclosures are introduced in a future phase, this policy will be updated prior to activation.
