Email masking

Masks the local part while keeping the domain visible.

Phone masking

Masks sensitive digits while preserving the format and visible suffix.

Builder-style API

Enable email and phone rules, and set the mask character explicitly before processing.

Install and run a first example

Install the verified Hex release, load the Elixir API, and run the minimal example below. It enables both masking rules explicitly and records the expected output.
