The server stores ciphertext and nothing else, so nobody at Aster can read your mail, scan it, or sell what is in it. There are no ads, no trackers, and no analytics anywhere in the app.\n\nPrivate by design\n- End-to-end encryption between Aster users, using a post-quantum ratchet protocol\n- Zero-access architecture: the server holds only encrypted content\n- No ads, no tracking, no telemetry, no profiling\n- Open source under AGPL-3.0, so anyone can audit what the app does\n\nEmail aliases\n- Create an alias for each site you sign up for, and turn one off when it starts getting spam\n- See which alias a message arrived on, right in the message list\n- Import and export your aliases\n\nYour own domain\n- Send and receive on a custom domain, with DKIM signing handled for you\n- Buy a domain from inside the app\n\nEveryday mail\n- Folders, labels, categories, and search across your whole mailbox\n- Swipe actions and a toolbar you can customize\n- Templates, signatures, scheduled send, and auto-forwarding\n- Blocked senders, sender filters, and an allow list\n- Encrypted offline storage, so your mail is there without a connection\n\nSecurity\n- Biometric lock\n- Two-factor authentication and a recovery key\n- Active session management, so you can sign out a device you no longer have\n\nNotifications\n- Private mode hides the sender and subject on your lock screen\n- Quiet hours schedule when notifications arrive\n- Per-folder muting\n\nThis F-Droid build contains no Firebase or Google Play Services dependencies. Push notifications are delivered through any UnifiedPush-compatible distributor, such as ntfy. Background polling takes over when no distributor is installed.\n\nAster Mail is free to use. Paid plans add storage, larger attachments, more aliases, and custom domains.\n\nSource code: https://github.com/Aster-Privacy/Aster-Android\n","categories":["Email"]}
