I see on my account page that there is a new page from Fairphone: Keep Club.
You can select your Fairphone (3/4/5) and the IMEI number. I didn’t read all the information. It looks like a membership for Fairphone where you can collect points and donate to ARM or discount on parts.

When you purchase spare parts and protective accessories you earn points with Keep Club. Turn those points into rewards and special perks on future orders.
