How I can save a level in player's data when player complete level and go to next level or when player quite the game. Thank you!

There are many, many different ways to accomplish this. Since your question is so broad, I can only offer broad answers for you to start your research, in rough order of complexity.

PlayerPrefs: If you have a very limited amount of save data, perhaps 5-10 data points, this is a convenient library provided by Unity to set and get strings, ints, and bools. It operates differently on each platform, but "just works" for the most part.

Writing to Files: If you have more data than should be saved using PlayerPrefs, or you'd like your files to be editable/readable/transferrable by your players (or you, during development, since PlayerPrefs writes to the underlying store in binary format, typically), you can do this. Google up "reading and writing files C#" for tutorials and APIs on how to do this. You can also obfuscate these files by encrypting/decrypting them, but you'll need to be aware that converting them to a binary format has security implications, so don't go down this route (encrypting) until you know what you're doing.

Writing to [remote] databases: If you have a great deal of data (images, audio, gigs of text), then a database might be an option for you. That's very much beyond the scope of this question, however, but you should know that it's relatively easy to do this with C#.

There are other esoteric solutions, obviously, but that should get you started.
