Frequently asked questions
How does the free preview work?
You can answer up to 100 questions for free. A one-time in-app purchase unlocks the full bank, adaptive exams and all future updates. There is no recurring subscription.
How do I restore Lifetime Access?
Open CISSP Vault, go to Settings and tap Restore Purchases while signed in with the Apple ID that made the original purchase. Apple handles the restoration; you will not be charged again.
Is my progress backed up?
Study progress is stored on your device. The app does not create an account or upload your study history. Deleting the app also deletes locally stored progress.
Does the app need an internet connection?
No for study features. The question bank, explanations, CAT-style exams and progress tracking work offline. An internet connection is only needed for App Store purchase or restoration.
Is this an official ISC2 app?
No. CISSP Vault is an independent study aid and is not affiliated with, endorsed by or sponsored by ISC2.
