BeReal is not good (most appropriate way i could say this). It is a Privacy nightmare. Just think about it, a bunch of random strangers are getting access to every single day what you and your family are doing. I know nobody is concerned about privacy anymore. Seems like we have lost that but still Also BeReal has a bunch of Ads. And since the inclusion of Ads bereal has quickly lost in popularity. If you are searching for a Alternative, you should try out DD-DigitalDiary It doesn’t have a lot of the features like social sharing. It is basically a journaling application. But still could be a good alternative. Also there was another app Minutaie which first started this trend so i suggest you should also check it out
I started using it a while ago. One big difference between iOS and android version. Android version is published by voodoo. Also, because of Adblock, I did not know or notice that it has ads. And my posts are only visible to friends for a day , not strangers for ever.
Do you know anything else , like what data they might collect?
Check permissions on your phone that should give some idea and read the tos. You likely won’t like it tbh but that’s standard with anything not foss
