Why is spyware legal?

Spyware is often legal because it can serve legitimate purposes, such as monitoring employee activity on company devices or parental control over children's online behavior. However, legality varies by jurisdiction and is typically subject to regulations that require transparency and consent. Many laws focus on how the spyware is deployed and whether users are informed about its presence. Additionally, spyware can cross legal boundaries if used for malicious intent, such as unauthorized data collection or invasion of privacy.
