Commercially available monitoring software sold to the public, typically marketed as parental control or employee monitoring tools. Products like mSpy, FlexiSpy, and Hoverwatch are sold openly, cost between 30 and 70 euros per month, and require approximately five minutes of physical access to a target device to install. After installation they run invisibly, do not appear in the standard app list, and often survive a basic factory reset.
What they capture: SMS, calls, WhatsApp messages, real-time location, browser history, photos, and in some versions keystrokes. The data streams to a web dashboard accessible from any browser with the account credentials.
On iOS without jailbreak: consumer spyware typically works through iCloud credentials rather than direct device installation. An Apple ID and password are sufficient — no physical access to the device is required, and nothing installs on the handset itself, making it harder to detect.
Legality: Installing monitoring software on another person’s device without their consent is illegal in most jurisdictions, including within marriage. The existence of a marital relationship does not create an exemption.
What it means in practice
Consumer spyware runs invisibly and does not appear in the standard app list. Signals worth investigating: battery draining faster than a month ago, data usage higher than your behaviour explains, the device warm when it should be idle. None of these individually confirms monitoring; several together, especially if the device has been in someone else’s possession, warrant a factory reset — but not before consulting a lawyer if you are in an active legal dispute, since documentation may matter.
