Signal is an end-to-end encrypted messaging app.

Sealed Sender

Since it’s a centralized service, Signal has access to all the metadata. While not as bad as having access to message content, metadata still tells a lot about your communications.

To improve this point, Signal has a feature called Sealed Sender.

You can check out the options related to this by going to Settings -> Privacy -> Advanced. For me, the Sealed Sender section is at the bottom of the settings screen.

Downsides

• Removed SMS support because they don’t have enough developer time, but still have enough time to integrate Giphy GIFs or sketchy cryptocurrencies
• Legally threaten open-source repositories that shipped Signal apps
