Data saved in your call logs includes the type of communication (e.g., phone call, fax, SMS message, or
voicemail), activity (missed call, etc.), call duration, date, and time.
The call details don’t focus on the exact phone call content (what was said on the phone). Instead, call logging collects and analyzes your phone calls' statistical and technical data.
Other call log information includes the caller ID, caller ID extension, call origin, call destination, and other transmission details, such as a phone call's start and end times. It may even indicate the specific network used.
