Yeah, adding my voice. Rescue time (and apps like it) are far too invasive (by necessity) for me to be comfortable with that data being sent remotely. It amounts to the single most invasive spy tool you could possibly install, since it's literally tracking every single thing I do. It doesn't matter how much you pledge to not spy on me, if you have my data you can change your mind at the drop of a hat.

There is literally nothing you can do to earn my trust with that much data - the rest of tech has not just scorched that Earth, they've glassed it. The only thing you can do that would make me consider becoming a customer is cut off your own ability to spy on me - by ensuring my data stays local and you have no access to it.

Editing to add: I considered Rescue Time in the past, used Freedom for a time (until I realized they were sending off my data and what that meant), then used qbserve for a long time. Stopped while ago when I realized I'd stopped looking at it and had stopped feeling like I needed it.
