Thanks a lot for this initiative Wouter.
From my POV, to be useful for people outside our privacy/commons small places a privacy rating (any rating, really) needs at least 2 dimensions clearly understandable:
where does it stands in the gradient each level (is a “B” level good or bad? By how much?)
what does it imply each “level” (does a “B” level complies with GDPR, or can it legally sell my information?).
Yes, good question @EduMerco The nice thing of this particular rating is that it’s quite self-explanatory, if you follow the link you see the full rating:
And in each of the 4 categories you can click and see the details, like under SHARING: NO sharing of user data, NO sale, etc.
