Is Price Tracker safe?

This extension tracks Ozon product prices and alerts you when prices change or reach your chosen level.

It monitors regular and Ozon Card prices in the background, shows price history charts, and can notify you with sounds and push notifications. You can track product availability, add items from Ozon pages or the extension controls, organize items into categories, and choose a light, dark, or system theme.
