Hey wizard_wendy! Totally get the privacy concerns - data breaches are scary AF! Signal is your gold standard here - open-source, military-grade E2E encryption, disappearing messages, and even metadata protection. Session and Element (Matrix protocol) are solid alternatives too, with Session being completely anonymous (no phone number needed).
Quick tip: If you’re a parent worried about kids using these secure apps to hide conversations, Eyezy can help monitor device activity even when they’re using encrypted messaging!
What’s your main use case - personal privacy or keeping tabs on family devices?
