CISSP covers the eight domains of the ISC2 Common Body of Knowledge, from security and risk management through software development security. It is a management-level exam: the right answer is usually the one a risk owner would choose, not the most technically clever one, and the 320-question bank is written to drill that instinct.

FAQ
What do I get before paying?
A free sampler of lessons plus a limited practice quiz, so you can judge the writing before you spend anything. The remaining lessons, the full question bank, the mock exam and the complete flashcard deck are behind the one-time unlock.
Is it a subscription?
No. One non-consumable in-app purchase unlocks the app permanently, and it is enabled for Family Sharing. There is nothing to cancel.
Do I need an account or an internet connection?
Neither. There is no sign-up, no login and no sync. All content is bundled in the app, so it works in airplane mode.
I paid and the app still shows the paywall.
Open Settings inside the app and tap Restore Purchases. That re-reads your Apple ID's purchase history. If it still does not unlock, email support with the Apple ID email you purchased with.
Does this replace the official study materials?
No. It is a study companion built to be used alongside the official objectives and hands-on practice. It is not affiliated with any certifying body.
