Closed can you check somewhere...?

i cant remember if i did or did not get a key for this game; i think i got one from my brother... but can you check somewhere if you have it registered or not?

would be nice if you could see it somewhere

 

I don't believe the keys to be linked to your account? (I could be completely wrong on this), so they would have no way of knowing if your account had a key, I suppose they could check if your email was used, but I think it's more between you and your brother to figure that out.

Edit: They could probably check if it was claimed by you on humble bundle.

 

already figured it out

 

For the future: https://www.humblebundle.com/?s=resender will email you all the keys used for your email.
