I'm making an online word game and I want to use a cookie to store the user's high score so it will always show it when they play the game, not just for the session. To comply with the EU GDPR do I need a cookie consent message for that? It will only be storing the high score, no name or email address or anything like that.
I think the answer is no. This page says
Not all cookies are used in a way that could identify users, but the majority are and will be subject to the GDPR.
That sounds like if there is no personal identifying information involved, such as just a high score, then GDPR doesn't apply.
