Indeed. That's why I like the privacy cards on the iOS App Store a lot. For apps like this, it makes it really easy to spot the ones that'll record my location data on their servers for some reason. It's the same with fitness tracking apps, so many of them send health data to their servers, but there are a few (often paid ones, of course) that seem to store important data only locally.
Can you name a few, please? I am very reluctant to fitness apps and devices for that exact reason and I'd really like to see a privacy friendly app. Bonus points if you know devices that can be used with local data only.
The major apps all have the ability to market weight loss products when you gain weight, for example, which is the thing I personally resent the most.
