One concern that many parents have is that anyone will be able to track their child using this child locator device and that will possibly place them in danger that they may not have otherwise been exposed to. This is not a problem though since the only people and phone numbers, which can access the device, are those you provide when you register your child location device. Each unit is allowed up to five people and numbers that they provide when they register, only these are allowed to access the unit and will receive alerts if the child uses the SOS button. Of course these names and numbers can be changed via your parent account in case there are any changes in the future.
