Use the Help Center first for setup instructions and common troubleshooting. For an account-specific problem, open Settings → Support in the Vault.
Support can help with sign-in, billing, Vault files, sharing, mail, calendar, contacts, security, privacy, and account status. It cannot recover information after permanent deletion or bypass a valid legal or policy requirement.
Include the exact error, affected app or device, when the problem began, and the steps that reproduce it. Never place a main password, Vault app password, Mail client password, backup code, payment-card number, or other authentication secret in a support message.
