Transfer data
Astral stores the account identifier—or an isolated guest identifier—plus file metadata and content in Firebase until the chosen expiry or earlier deletion. Share links are unlisted but accessible to anyone who has a valid unprotected link.
Service providers
Firebase and Vercel process technical data needed to authenticate, store, and serve Astral. Stripe processes billing data for paid plans. Google can process advertising data only where an eligible ad surface is used and the required consent has been granted.
