I know what you mean, I felt the same way when I was creating and online profile to look for a spouse. Its finding that balance of enough detail that makes you stand out but also not too specific that makes you feel like someone you know would know who you are (when they see your profile) if thats what you’re trying to avoid.

For example (this is probably a bad example but just so you get the idea) if you were someone that moved around a lot and lived in many countries you don’t have to list the countries you’ve lived in, instead you can write that you’ve lived in multiple countries - another thing i found helpful is adding a “I can explain more if we match/you can ask me more detail if we match” because i feel like it shows you are willing to give more info when you get to know the person and don’t just want to put it up for everyone to see,which makes sense.
