No. This is because phone tracking apps are technically not illegal. Anyone can use them to search phone number location but they can only be utilized for personal reasons. In other words, you can use these services to conduct simple background checks but the information can’t dictate leasing, employment, or even credit decisions. With that said, phone tracking apps should only ever be used ethically. This means you can’t use them to harass, stalk, or defraud anyone. In most cases, you can track someone’s phone legally with their consent or if you’re a parent/guardian monitoring a minor. However, it’s best to check with your local state laws beforehand to verify compliance.
