In general, it is not illegal to track someone else's cell phone, but there are a few things to bear in mind. You can track your minor children at any time without their knowledge or consent. The same applies to people in need of help for whom you have guardianship or a similar duty of care. Some employees (especially those working in the field) may also be tracked by their employer without their knowledge or consent. Anything outside of these scenarios may be in a gray area. If in doubt, we recommend seeking legal advice before using our software.
