Hello derfplik,
Please check out the following link, which explains how AirTag works, and may be helpful: Find your keys, backpack, and more with AirTag
AirTag helps you keep track of and find the items that matter most. If you misplace an item and it's nearby, use Precision Finding—on supported iPhone models—to guide you to it. You can also use the Find My app to play a sound on your AirTag, find it on a map, or get directions to it.
If you have concerns about unwanted tracking, please check out the details in the "Unwanted tracking" part of this link, which outlines what to do: What to do if you get an alert that an AirTag, Find My network accessory, or set of AirPods is with you
Unwanted tracking
If any AirTag, AirPods, or other Find My network accessory separated from its owner is seen moving with you over time, you'll be notified in one of two ways. These features were created specifically to discourage people from trying to track you without your knowledge.
1. If you have an iPhone, iPad, or iPod touch, Find My will send a notification to your Apple device. This feature is available on iOS or iPadOS 14.5 or later. To receive alerts, make sure that you:
• Go to Settings > Privacy > Location Services, and turn Location Services on.
• Go to Settings > Privacy > Location Services > System Services. Turn Find My iPhone on.
• Go to Settings > Privacy > Location Services > System Services. Turn Significant Locations on to be notified when you arrive at a significant location, such as your home.
• Go to Settings > Bluetooth, and turn Bluetooth on.
• Go to the Find My app, tap the Me tab, and turn Tracking Notifications on.
• Turn off airplane mode. If your device is in airplane mode, you won't receive tracking notifications.
An AirTag, AirPods Pro (2nd generation) charging case, or Find My network accessory that isn't with its owner for a period of time will emit a sound when it's moved.
If you detect an unknown AirTag, Find My network accessory, or AirPods, use the steps below to learn about it, find it, and disable it. If you're using an Android device, you can download the Tracker Detect app to find an AirTag or Find My network accessory that's separated from its owner and might be traveling with you.
Thank you.
