Signal’s advanced privacy-preserving technology is always enabled, so you can focus on sharing the moments that matter with the people who matter to you.
• Say anything – State-of-the-art end-to-end encryption (powered by the open source Signal Protocol™) keeps your conversations secure. Privacy isn’t an optional mode — it’s just the way that Signal works. Every message, every call, every time.
• Go fast – Messages are delivered quickly and reliably, even on slow networks. Signal is optimized to operate in the most constrained environment possible.
• Feel free – Signal is a completely independent 501c3 nonprofit. Development is supported by users like you. No advertisements. No trackers. No kidding.

• Speak up – Whether they live across town or across the ocean, Signal’s enhanced audio and video quality will make your friends and family feel closer.
• Whisper in the shadows – Switch to the dark theme if you refuse to see the light.
• Sound familiar – Choose custom alerts for each contact, or disable noises completely. Simon & Garfunkel wrote a hit song about it in 1964, and you can experience the sound of silence whenever you want by choosing “None” as your notification ringtone.
• Picture this – Use the built-in image editing features to sketch, crop, and flip your outgoing photos. There’s even a text tool so that you can add more words to the 1,000 that your picture is already worth.

Data safety

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
If you don't update the app, the pin does not work, and the application gets on a loop for bad pin or error connecting to service without giving a notice that the app needs to be updated. Even if someone resets the pin, the new one is not accepted because of the same loop. So you have to become twice frustrated before you either uninstall and install the app or just update it. Anyway, I already lost all my previous messages and groups. Thank you.

I like the app, but lately I've been having issues regarding voice recording through android auto. It does not let me record a voice message more than a second, than it starts a call that does not exist and cannot be ended, which causes an audio or music to not be able to play. When I am able to record a voice message somehow, the quality is incredibly bad. I don't know if it's because the integration between them is not yet alright, though this kind of becomes frustrating.

Signal is great and had a 5 star but recently I noticed that the notifications are not consistent. There are times when I do not get the notifications of a text that has been sent. I only get them when I open the app and it could have been hours before that someone sent the text. I also miss the feature that allowed you to delete all messages at one time. Now you must delete them individually. The auto-delete after a certain time period is a cool function.
