Data safety

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
Such a great idea and totally reliable (in that, eventually, it always opens the door), yet just incredibly slow and inconsistent. Sometimes it opens everything straight away, sometimes you have to wait minutes(!) only to have the doors open when you're long inside. It's just so frustrating and ludicrous. Also, one has to restart the app regularly whenever the status can't load.

Hello Lennart,
we are sorry you are unhappy with how your Smart Lock works. A delayed Auto Unlock is caused by the Smart Phone updating the location data too late. There is unfortunately nothing the Nuki App can do to change this behaviour as the App and the Smart Lock are just trying to trigger the Auto Unlock as soon as possible.

This now appears to need a setting called "Location Accuracy" to be switched on, even though it did not require it previously. This setting is a huge privacy hole, though, as it allows your phone to be tracked almost everywhere, even if you switch WiFi off. It really shouldn't be a prerequisite - the user (who owns the phone and the Nuki!) should have the choice to use GPS only, which is generally sufficient for this use case. Edit: No doubts, this setting is the issue.

Very happy after 6 weeks. Works great! Minor improvement suggestions: make smaller widgets (currently 1x5 or 2x3), they take too much space on the homescreen. Also removing the notification dot would be nice.
