Premium

Premium is explained clearly, not dressed up with fake numbers.

This website does not invent pricing cards or mock trial claims. Premium purchase and restore stay inside the Android app through Google Play, while the website explains the value cleanly.

Billing facts

Study.IO does not run a separate website checkout. The website describes the product, but purchase, restore, renewal, and billing management remain tied to Google Play.
