What it does
koalo.cc offers encrypted mail and an integrated password vault. Its page distinguishes messages between koalo users from outside mail and discloses truncated login records and remote-image behavior.
koalo says messages between its own users are encrypted before leaving the device. Its page also states that external images load in outside mail, allowing an outside sender to learn that a message was opened.
Signup needs no phone number or backup email under the described workflow. Sign-in records use a truncated network address and remain for 90 days, so reducing the address detail does not mean there are no account-activity records. The included password vault is part of this same mail service.
