This policy explains what cehstudy.com does and does not do with your information. In short: there are no accounts, we never ask for personal details, and the only third-party technologies on this site are Google's advertising services, disclosed in full below.
CEHStudy is a free study resource. You do not need an account, an email address, or any other personal information to use the flashcards, practice questions, module notes, or glossary. We do not collect names or contact details from visitors, and we do not sell or share visitor information with anyone.
The flashcard app keeps your study progress in your browser's local storage — which cards you have reviewed, where you stopped in a deck, and per-module progress counts. This data:
