I like the idea, but I wonder how this works in practice. If I grant ACME Inc. access to my “profile picture,” for example, won't they just copy the file and store it on their own servers (be it for performance reasons, tracking, ease of development, whatever)? How does this keep me in control?
Another vote for the Pocketbook (~€100 on online stores in Europe). As the parent above, I never connected it to the internet, not once. I use a USB cable to add new books. The Pocketbook is also recommended by Mozilla's Privacy Not Included list as the most privacy-friendly e-reader. I wrote a blog post about my Kindle → Kobo → Pocketbook experience: https://suffix.be/blog/search-perfect-ereader/
Good on them but how does this work? If my neighbour scans my WiFi network and uploads it to BeaconDB I didn’t exactly opt-in, did I? The privacy policy mentions you can add ‘_optout’ to the WiFi name, so it’s more opt-out instead of opt-in?
I still don't understand how one can retract access once given. If I share my purchase history with some financial web app and later decide to retract access the web app will no longer get new data, but how can I be sure they don't keep a copy of my old data around? Same with GDPR. I often ask companies to remove my data, and legally they should, but I highly doubt many of them do indeed scrap all my data. I still need to trust the other party to honor my wishes (and follow the law) which makes me wonder if Solid or Schluss can help removing my data.
I always wondered if this is US specific. In Europe, as far as I know, the package would simply be delivered by the neighbor, they return the next day, or you have to get it from the local convenience store or some centralized lock-box.
I have been using Prowl (https://prowlapp.com) for years now as the generic push notifications app. You pay a $3 one time fee and send notifications via a webhook.
