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.
Overall I'm very happy with the app for a long time now. Have an issue recently, though: When I attach a file to a message in 'Note to self', it looses the original name of the file. Instead, the filename is always 'Unnamed file'. Can you please have a look into this? Thx. Otherwise, keep up the good work!

Love signal! however I've noticed a bug to PLEASE FIX♥️: the calls do NOT ring, even with notifications on in the app, and in settings, and the phone in full ring mode. it's very frustrating because I keep missing calls. DEVELOPERS, PLEASE FIX AND I'LL BE VERY VERY GRATEFUL. i use it for a lot of my messaging and it's easy to back up messages.

A nice alternative to other messaging apps. However, I frequently experience issues with missed notifications, calls don't always ring, call quality can be poor/average, and on occasion, messages don't appear for a period of time (up to 30 minutes). The message then suddenly appears dated/timed 30 minutes prior.

We sped up the performance of scrolling in long chats. If you are in a big gardening group, now bloom scrolling is also vroom scrolling.
