Important: It is important to note that some of the CR2032 batteries come with a “bitterant” coating as well. According to Apple, such batteries will not necessarily work with Apple AirTags. So, make sure that you purchase batteries that don’t have any “bitterant” coating on them.

The Privacy and Security of Your AirTags

If you possess multiple AirTags, each one is uniquely associated with your Apple ID. In addition to that, it cannot be traced by anybody but yourself.

The AirTag does not keep track of where it has been or where it has been in the past. So, everyone involved can rest assured that their privacy will be protected.

If your misplaced AirTag is scooped up by another device, you can see its position on a map. However, you will not be able to find out who helped you recover it.

Since AirTags are transmitted using end-to-end encryption, even Apple cannot decipher their precise locations. Thanks to AirTags’ dynamic Bluetooth identifiers, you can move around without worrying about being followed.

Traveling with Your AirTags

There are restrictions that apply to using an AirTag when you’re on the road. Examples of countries where Precision Finding won’t function include Russia, Argentina, Indonesia, and so on. The full list can be seen in the AirTags travel guide.
