"personalized service"
to adapt something to the needs or tastes of an individual

In plain English: To personalize something means to make it special by adding your own unique style, choices, or identity to it.
"You can personalize your mobile phone by changing the background image and adding custom wallpapers."
Usage: Avoid using "personalize" when you simply mean to make something private; instead, use "privatize." In formal writing, consider "tailor" as a more precise alternative for adapting services to specific requirements.
The word personalize comes from combining the adjective personal with the suffix -ize to mean making something specific to an individual. It entered English as a straightforward formation that retained its original sense of adaptation or customization.
