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
You should assume that whatever you upload to the internet without encryption is public. Bereal was always advertised as a tool for sharing your life with others, so this isn’t unexpected for me. The only misleading part is that if you share with friends only, it’s not just your friends, but also the service provider, so you should assume that it may leak. I never used bereal so I’m not familiar with its features, some of my friends use it and I just heard about it from them. From their description it didn’t sound as an app where you should expect privacy.
Is Lemmy a privacy nightmare? No, because you know that everything is public here, admins can even see your DMs.
Do not share private data on the public internet
There are probably users who don’t know this. And I reckon most users don’t know that anyone can see everything you upvote and downvote (with a little effort).
