What can MDM see on my phone?

Excuse me, could you please elaborate on what MDM is capable of observing on a smartphone? As an individual who values their privacy, I'm curious to understand the extent of its monitoring capabilities. Is MDM limited to only specific data points, or does it have a broader scope that encompasses sensitive information like messages, browsing history, or even camera footage? Additionally, are there any safeguards in place to ensure that this data is handled securely and with respect for users' privacy concerns?
