The banner, and the notes under it.
This page explains the small notes pokerblinds.net keeps on your browser. I am writing from a bus window in Finland. The pastime is free, and it is for adults who are 18 or older.
The banner along the bottom links here. When you press Accept, I store yes. That is how I know you saw this note. If you have not accepted, the banner can stay in view.
I also store an age yes when you confirm you are 18 or older. I store one player object if you sign up, and a session name while you are on the ride. Those values let the header show your name and let a stub open.
The notes live in localStorage on this device. I do not use them to follow you onto other sites. I do not sell them. If you clear site data for pokerblinds.net, they go away.
If you want this in simpler words, write hello@pokerblinds.net. I will answer as a person, when the next stop gives me time.
