If I have to have a firm to upload my game on Google Play?

Hey, can You tell me if I need a firm to upload my game on Google Play?

I'm asking because every game I saw has got a company name displayed on beginning.

No you can upload it as an individual. But usually people prefer to upload it using an alias or a studio name instead. But its up to you

No, you dont need to. As a matter of fact you can actually find a lot of games under just the author's name (for example: myself )

If you plan of uploading paid apps or games with in-app purchases, you'll need to make a "google merchant" account and you will be asked about things like your bussiness name and such, but you can just input your personal data.

If you are still there or someone else can answer: (excuse my english)

Can customers view your personal data? in google merchant you must register, for example, contact name, bussiness address, phone number, etc.

I have no registered bussiness, so this is the first game I develop.

Can I register with my personal info and still be safe?

Thanks
