Privacy Policy

Effective date: April 30, 2026

This site (93.fyi and its subdomains) is a personal, family-use project. It is not a commercial service.

What we collect

The web app stores preferences and progress locally on your device using browser localStorage. No data is sent to a server, no accounts are created, and no cookies are set by the app itself.

If you send an SMS to our phone number, your phone number and message content are processed by Twilio (our messaging provider) and used solely to reply to your question. We do not share your number with third parties or use it for marketing.

Hosting & analytics

The site is hosted on Vercel. Vercel may collect standard web-server logs (IP address, user agent, timestamps). We do not run any additional analytics, trackers, or advertising scripts.

Data retention

LocalStorage data stays on your device until you clear it. SMS messages are retained by Twilio per their retention policy and in GitHub (as private issues) for the purpose of answering your questions. We do not sell or share this data.

Contact

For questions about this policy, contact the site owner directly.
