【"Find My" Network Compatibility】 Utilize Apple's "Find My" network, compatible with iPhone, iPad, and Mac, to quickly and accurately locate lost items. *This product is exclusively for iOS and is not compatible with Android devices.* Location updates depend on the number of Apple devices in the vicinity of the product (if there are few Apple devices nearby, updates may be delayed or temporarily suspended). 【Anti-Forgetfulness Alert】 By enabling "Notify When Left Behind" in the "Find My" app, you'll receive an instant alert the moment the tag and your smartphone move a certain distance apart. Even if you accidentally leave something behind, you can quickly realize it and go back to retrieve it, preventing the loss of important belongings like keys, wallets, and bags, adding peace of mind to your daily life. 【Easy Finding with Sound】 Simply tap "Play Sound" from the "Find My" app, and the tag will emit a sound at a volume of up to 100dB, indicating its location. It's clearly audible even in hard-to-see places like the bottom of a bag or the gap in a sofa, freeing you from the hassle and anxiety of searching. 【Replaceable Battery and Excellent Portability】 Uses a standard CR2032 button battery (sold separately) and offers up to a year of use thanks to its low-power design. The battery can be easily replaced when it runs out. The AirTag itself is lightweight at only 7.9g and slim. Using the included two silicone straps, you can attach it to various items such as keychains, wallets, bags, and suitcases for easy carrying. 【Tracking Prevention Function to Protect Privacy】 If a tag is placed on your belongings by a third party, your iPhone will detect it and notify you. If the tag is not found after a certain period, it will emit a sound to indicate its location. All location information communication is anonymous and encrypted, and the history is not saved on the tag itself. Only the user can access the information. No one, including Apple, can track you, ensuring high privacy protection.
