Quick Facts:
The blockchains Graflr uses are not private. User wallet addresses are public. (Private keys should remain with your wallet solution.)
Graflr is about minting the moment. That moment may include:
Your face, other faces around you
Your location (VIP may have shared it, even if you did not)
The time the photo was taken
The NFT has cryptographic proof the NFT form was signed by your private key. And the time I am pretty sure is available for that, as the public indexers take over from there to list the NFT in the marketplaces.
