Contacts added to one account never appear in another. You can also import only the contacts you select from your device. PRACTICAL PRIVACY Passwords remain in the device’s secure storage. Message content and attachments travel directly between your device and your IMAP/SMTP servers. CubMail displays Google AdMob ads after gathering privacy choices and offers a one-time purchase to remove them. Your email content, contacts, and IMAP/SMTP credentials are never sent to AdMob. NOTIFICATIONS WHILE THE APP IS CLOSED When enabled, our private encrypted relay reads only the headers required to detect new mail. It never downloads message bodies or attachments. Removing an account also removes its local secret, contacts, and local and remote notifications. MORE INCLUDED Biometric lock, light and dark themes, widget, shortcuts and nine languages. GOOD TO KNOW Your provider must allow password or app-password access. Google and Microsoft OAuth are not available yet.
