Privacy Policy
Last updated October 11, 2026
The short version
We hold what it takes to run Lux for your family, and nothing to sell. We never sell personal data, and we run no advertising trackers.
Parents
When you join the waitlist or subscribe, we hold:
- Your email address, and your name once you create an account
- Your subscription and billing history
- The emails we have sent you
Card details are handled by Stripe and never reach our servers. See Stripe’s privacy policy for what they keep.
Kids
A parent gives us each kid’s grade and, if they like, a first name. During a session, Lux hears your kid and sees the worksheet so it can help. Our COPPA policy explains exactly what a session keeps, who processes it, and how long we keep it.
Visitors
Browsing the site needs no account. We do not run third-party advertising trackers or build profiles of visitors.
Who processes data for us
- Stripe, for payments
- Resend, to send our emails
- Cloudflare, for hosting
- Our database provider, for storage
- OpenAI and Anthropic, to run sessions, as the COPPA policy describes
Nobody else. We disclose data only when the law requires it.
Your choices
Ask us for a copy of what we hold about your family, ask us to correct it, or ask us to delete it. Email hello@learnwithlux.com. We answer within 30 days. We keep billing records for as long as tax and accounting rules require, and delete the rest on request.
