THE SMALL PRINT, IN PLAIN WORDS

Your study. Your space.

Privacy policy for AWS DOP-C02 PREP and this website. Here’s what stays on your device and when a network connection is involved.

Effective: September 28, 2026

No sign-in

No account is needed to study. Your profile name is a local preference.

Optional analytics

Firebase Analytics measures app usage; turn it off in your profile. No ads or cross-app tracking.

Progress stays local

There is no developer-operated server receiving your study history.

01. What the app stores locally

The app stores your study history, answers, saved questions, active sessions and exam timer deadline on your device. It also stores your chosen profile name, language, planned exam date and reminder preferences. These values support progress tracking, session recovery and personalization; they are not sent to a developer-operated backend.

Reminders use Apple’s local notification system. Permission is optional and can be changed in iOS Settings. The app does not register with a developer push-notification service.

02. When the app connects to the internet

Question text is bundled with the app. Some illustrations load from Google Firebase Storage, which receives technical request information including your IP address. Firebase Analytics also collects app interactions, anonymous installation identifiers and aggregated study activity (session mode, question count, score, duration and bookmark changes) for app improvement. We do not send your profile name, question text, answer choices, question IDs or planned exam date. Analytics is not used for advertising or cross-app tracking. Turn off Usage analytics in your app profile anytime to stop collection and reset the local Analytics identifier. Data already received by Google follows its retention policy; contact us for a deletion request.

Google privacy policy

You can study bundled text offline. Remote illustrations may be unavailable without internet.

03. If you email support

If you contact tienlab19@gmail.com, your email address, message and any attachments are received through our email provider. We use them to answer your request and investigate reported issues. Please do not send passwords, payment details or sensitive personal information. Support correspondence is retained only as needed to handle and follow up on the request; you may ask for deletion by email.

04. This website

This site uses no advertising, analytics scripts or marketing cookies. It stores only your chosen website language in your browser’s local storage. Fonts and app images are served with the site, without third-party embeds.

When served through GitHub Pages, GitHub may process visitor IP addresses and technical request information for security and operation of its hosting service. We do not receive individual visitor analytics from this site. External links and your email application have their own privacy practices.

GitHub privacy statement

05. Your choices and deletion

  • Change your name, language and planned exam date from the app profile.
  • Manage notification permission in iOS Settings.
  • Deleting the app removes its local app data. Offloading is different: iOS may keep app data. Device backups and restores are controlled by your Apple settings, not by a cloud-sync feature in this app.
  • Clear this website’s browser storage to remove its saved language preference.

06. Changes and contact

This policy describes the current version of the app and website. If data handling changes, this page and its effective date will be updated. For questions about privacy or a support-email deletion request, contact the app developer at:
