What we hold
Email, billing identity, device public keys, region preference, account.country_code (sourced from App Store storefront → Play regionCode → Cloudflare CF-IPCountry → user-declared; XX fallback; Tor → T1). For each signed-in device we keep the IP address and approximate location (city and country) it last signed in from, so you can spot devices you don’t recognise. For Mail and ticket bodies we hold ciphertext encrypted at rest: each object is encrypted under its own key, and that key is wrapped by a server-held master key. Vault items stay on your device.
