Account: the email address (and name, if your sign-in provider shares it) from your Decryption Digest account, and an internal account id. You sign in on our portal with Apple, Google, Microsoft, or an email link.

Study data: flashcard progress, practice exam answers and scores, streaks and daily activity, your chosen exam, exam date and goals. We save these so your progress follows you across devices.

AI tutor: the messages you send to the tutor and the card or question you were viewing, plus any problem reports you submit.

Purchases: your subscription status. Apple handles payment and we never see your card. We receive purchase status through RevenueCat, which is given your account id and App Store receipt information.

Only on your device: study settings, your reminder time and local notifications, and saved headlines.

Location, contacts, photos, microphone, advertising identifiers, or analytics and crash data from inside the app. We do not track you across other companies' apps or sites and we do not sell your data.

To run the app, sync your progress, build your daily plan, answer tutor questions, apply your subscription, and fix content errors you report.

Cloudflare hosts our API and runs the AI model that answers tutor questions. Cloudflare states that it does not use customer content processed by Workers AI to train AI models, and does not keep inputs or outputs for standard requests beyond what is needed to answer them.

Neon hosts the database that stores your progress and tutor messages.

RevenueCat and Apple process subscriptions.

Apple, Google and Microsoft verify your identity if you choose them to sign in. Signing in opens our portal in your browser, and the site privacy policy covers the portal.

We keep your tutor messages ourselves so they can be shown in your conversation and removed when you delete your account.

In the app, open Account and tap Delete my account. This erases your progress, streaks, exam history and tutor messages from our servers, then opens our portal so you can confirm deleting your Decryption Digest account and sign-in methods, including revoking Sign in with Apple. If you are the only owner of a team that has other members, or you have an active web subscription, deletion is blocked and the page tells you what to do first.

Deleting your account does not cancel an App Store subscription (cancel it in your Apple ID settings) and does not remove you from the newsletter (use the unsubscribe link in any email). Copies may remain in our providers' backups for a limited time before they are overwritten.

DD Academy is not directed to children under 13 and we do not knowingly collect their information. If you believe a child has given us information, email us and we will delete it.

You can ask for access, correction, export or deletion at info@decryptiondigest.com. People in the EU, the UK and California have the rights described in the site privacy policy.

We will post changes to this page and update the date above.

DD Academy is a study app for cybersecurity certification exams. It provides flashcards, practice questions, a study plan and an AI tutor. It is an independent product of Decryption Digest.

CompTIA and Security+ are registered trademarks of CompTIA, Inc. DD Academy is not affiliated with, sponsored by, or endorsed by CompTIA or any other certification body. We do not guarantee that you will pass any exam, and scores and readiness figures in the app are estimates, not predictions.

Questions and explanations are written to published exam objectives and may contain errors. The AI tutor can be wrong. Check important facts against official sources.

You need a Decryption Digest account to sync progress and use paid features. Keep your sign-in secure and do not share your account.

The full plan is an auto-renewing subscription (monthly or every 3 months). New subscribers may get a 7 day free trial, and a payment method is required to start it. Payment is charged to your Apple ID at confirmation of purchase, or when the trial ends. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel in Settings, your name, Subscriptions. Any unused part of a free trial ends when you buy a subscription. Refunds are handled by Apple.

Do not copy, resell or scrape the content, try to extract the question bank in bulk, attack or overload the service, or use the AI tutor to produce harmful or illegal content. We may suspend accounts that do.

The questions, flashcards, explanations and app are ours or our licensors'. We give you a personal, non-transferable license to use them for your own study. Your progress data is yours.

The service is provided as is. To the extent the law allows, we are not liable for indirect or consequential losses, or for exam fees or career outcomes, and our total liability is limited to the amount you paid us in the 12 months before the claim.

We may update these terms and the app. You can stop using the app and delete your account at any time. Questions: info@decryptiondigest.com.
