To start, consider Signal, Telegram, or one of a handful of secure messaging apps—even iMessage conversations are end-to-end encrypted. We covered six excellent choices in early 2021 when WhatsApp announced it planned to share more user data with its parent company, Meta (formerly Facebook), and you should be able to find one that fits your needs. It’s worth noting that Facebook Messenger comes with E2E encryption, but you’ll have to turn it on yourself. You may also find it useful to send self-destructing messages on social media and other platforms.
One easily overlooked feature here is location sharing, which is available in various messaging apps but not restricted to them. It can be useful to help others understand where you are, perhaps for travel or safety reasons, but you likely don’t want to broadcast your location to the world. Take a minute to check where you could be sharing this information and confirm your location sharing settings are exactly what you want them to be.
