How Apple's crowdsourced network finds a tracker — and how HH-Tech tags plug into it, safely.
Apple Find My is a crowdsourced network of over a billion active iPhone, iPad, and Mac devices. When an HH-Tech tracker goes out of Bluetooth range, nearby Apple devices anonymously detect its encrypted BLE public key and relay the location to iCloud — end-to-end encrypted, so not even Apple knows who found what.
Apple's Find My lets a single account track up to 32 items — AirTags and third-party Find My network accessories combined. Enough for every key, bag, and bike in the house.
All 32 appear in one map in the Find My app. Lost anything — tap its entry to ring it, follow it, or share it with trusted friends.
An item can be shared with up to five other people — six users on a single tag, each able to see and locate it in their own Find My app.
Your tag emits a low-energy Bluetooth signal carrying a rotating, encrypted public key — unreadable to anyone nearby.
Any Apple device passing by anonymously picks up the signal and uploads its location to iCloud. The passerby's identity is never shared.
Only your phone — holding the private key — can decrypt the location and show where the tag is. Apple stores it, but can't read it.
Find My uses end-to-end encryption with rotating keys every ~15 minutes. The public key changes constantly, so no one can track a tag's movement over time — not passersby, not Apple.
Apple requires every manufacturer on the network to detect whether a tag is moving with an unsuspecting person. When an unknown tag travels with you, Find My sends a "moving with you" alert and can play a sound to locate it.
Apple requires all Find My tag makers to monitor movement through hardware. In every HH-Tech tag, an accelerometer and a vibration sensor are embedded directly in the circuit — so the tag itself can tell when it's being carried, and trigger the anti-stalking safeguards.
Apple and Google worked together on a common specification so both iOS and Android users get alerted if a compatible Bluetooth tracker is following them — reducing misuse of a technology meant for finding things.
Find My is designed to locate items — keys, bags, luggage, bikes. Apple, and HH-Tech, do not permit these tags to be used to track people or pets. To further deter misuse, crowdsourced location updates are intentionally delayed rather than real-time. Safety and consent come first.
HH-Tech received Apple Find My certification in 2023, becoming one of the early hardware companies approved to ship trackers on the network. Our Smart Tag for iOS and Smart Card are built for it — precision-tuned antennas, pre-qualified silicon, embedded motion sensors, and full compliance.
