Chattr vs WhatsApp
WhatsApp uses end-to-end encryption by default, but it is owned by Meta and requires a phone number. Chattr collects no data for an advertising ecosystem and lets you create an account anonymously.
WhatsApp has stronger protection of message content — it is end-to-end encrypted by default. Choose Chattr if you'd rather not hand your phone number and conversation metadata to a large advertising company, and you need a connection on restricted networks.
