When you create a profile more or less questions can be asked. Try to keep as little information about yourself as possible.
The wonderful thing about a dating app is that you can be very anonymous. So don’t give away too much personal information. She doesn’t need to know your address, full name, employer, favourite restaurant, sports club etc.
Tell rather generally about your hobbies, what you like to eat, which music you like to listen to, which movies and series you like to watch or where you like to go on vacation.
Only give up your anonymity when you have really gained confidence in your flirt partner. However, this can usually happen even after 2-3 dates.
Keep it really low key when it comes to your last name. If you tell her, she will google him and maybe find out more about you, e.g. what sports competitions you have participated in, what company you work for, etc. By withholding your name, you avoid internet stalking. She might also use the stolen information against you and threaten you (e.g. she outes you to your employer).
Choose a neutral profile name. Make sure that it is not necessarily childish, provocative or forced erotic like “SexyMausileinXXX”, but a neutral name like “Ada88 *Rainbow-Emoji*”. So there will be no misunderstandings about your intention (to find the woman of your life).
Also, your profile picture should be neutral and not show any bare skin (you are sending a clearly ambiguous signal). You and your eyes should be clearly seen. .
