I have a Tile and sometimes use the app, but there is absolutely no reason why the app needs constant access to your location. When I need to find my keys, I open the app and press the "Ring" button...even at that point, Tile has no reason to know my location. The app still works if you disable location access but it pesters you incessantly to re-enable location services.
This is incorrect. Tile has two
very good reasons to constantly track user location. It is fundamental to how it works.
1) Let's say Bob loses his widget somewhere while running errands. Bob doesn't know where. If Tile (the app/service) had constant access to Bob's location, it will know the last time and location Bob's widget was in range of Bob's phone, because it had been tracked. Bob can go to that last known location, press the Ring button, and find his widget.
On the other hand, if Bob had location tracking turned
off, then Tile has no idea where and when the widget was last in range of the phone. Bob will have to retrace his route of errands, constantly hitting the Ring button every 10 feet due to the short range of Bluetooth, and hope for the best.
2) Let's say Sara has a Tile on her ferret's collar. The ferret gets loose accidentally and is running around the neighborhood. Sara had location tracking turned on for Tile, but it doesn't really matter since the last reported location in range of her phone was the ferret at home.
However, thankfully, there are many other Tile users around. And when Sara reports her Tile lost, the entire Tile Community Network looks for the ferret. If and when the ferret ever gets in range of
anyone's Tile, it is reported to Sara. In a twist of fate, the ferret is hiding out near Bob's house, and because it is in range of Bob's phone and he has location tracking services on, Sara can go get her ferret.

So you can see, every single person turning off Tile location services loses feature #1 and weakens feature #2.
If you have location services off, then you are unable to benefit in scenario #1, and you are also refusing to help others find their items in scenario #2. That's totally fine, use the product however you like. Maybe you only need a "I want to find something I set down in the house somewhere" device, and maybe you prefer higher personal privacy over helping others.
But that is NOT the same as saying Tile has absolutely no reason to have location services on. They have very good, fundamental reasons for wanting that to be on.
