About this app

Prepare for the Certified Data Privacy Solutions Engineer (CDPSE) exam with 750 original privacy engineering practice questions across all 4 CDPSE domains — each with a detailed explanation and a one-line tip. A focused privacy engineer certification study tool for privacy, data protection and security professionals.

WHAT YOU GET
• 750 unique CDPSE practice questions, about 188 per domain
• A full explanation for every question — why the best answer is best and the others are not
• Study by domain, ordered easy → hard, so you build up instead of guessing
• A timed 120-question mock exam (210 minutes) drawn across all four domains
• "Review my mistakes" mode that drills exactly what you keep getting wrong
• Per-domain performance stats so you can see your weak domains before exam day
• Study offline — on the train, on a plane, anywhere (purchases need a connection)

WHAT IT COVERS — THE 4 CDPSE DOMAINS (exam weight)
• Privacy Governance (20%)
• Privacy Risk Management and Compliance (18%)
• Data Life Cycle Management (23%)
• Privacy Engineering (39%)

SAMPLE TOPICS FROM THE QUESTION BANK
Privacy by design · privacy impact assessments (DPIA) · data minimization and purpose limitation · consent and privacy notices · data inventories and data mapping · retention and deletion · data subject requests · pseudonymization, anonymization and k-anonymity · differential privacy, tokenization, masking and homomorphic encryption · processors and cross-border data transfers · breach notification · LINDDUN privacy threat modeling · GDPR and CCPA.
Many questions are short workplace scenarios: a new data flow, a vendor arrangement or a system design — and you decide what the privacy engineer should do first.

ABOUT THE SCORING
The CDPSE exam is scored on ISACA's 200–800 scale with 450 to pass; ISACA does not publish a raw-percentage equivalent, so the mock exam uses 65% correct as an approximation. All questions are original, created with AI assistance — no recycled, leaked or copied exam content.

HOW CREDITS WORK
Install the app and you get 20 free credits as a one-time welcome gift — enough to open exam-style questions and see exactly what you are getting, with no account and nothing to pay. Viewing a question costs 1 credit and revealing its answer and explanation costs 1 credit; a question you have opened stays open. The 120-question exam simulation costs 120 credits — half what the same questions and answers cost one by one — and passing it gives 24 credits back.
More credits come in packs of 100, 250, 500 or 1,000 — a one-time in-app purchase each, no subscription, no auto-renewal, and credits never expire (they are stored on this device).

PRIVACY
No account, no ads, no tracking, no analytics. Your progress is stored on your device (and in your own Android backup, if you have backup turned on).
