Who else sees your data
Google, when you choose to sign in with Google. We receive your account identifier, email and name; Google sees that you signed in to G20X. We never receive your Google password.
Stripe, when you buy credits. Stripe handles the card details — they never reach our servers. We receive a payment identifier and the amount. Stripe's own privacy policy governs what they hold.
Cloudflare, which hosts this site, serves the audio files and runs our database. They process requests on our behalf.
Travel booking partners, when you click a booking link and leave our site. From that point their policies apply, not ours. We see that the click happened; we do not see what you booked or paid.
