If your tracker falls into the wrong hands there is no way they can find out who owns it. Similarly there is no way they can re-purpose the tracker and use it for themselves or view historical data. Please note that our devices are designed to allow you to track your own property and that in many countries it is illegal to track someone else or their property without explicit consent. Please refer to local regulations before using LightBug devices. We will co-operate with authorities and where illegal use has been identified, provide evidence which may be used for prosecution.
