In short
- Your study progress and settings stay on your phone.
- There are no accounts. We never ask for your name, email, ID number or phone number.
- Data leaves your phone only through Google's advertising, or when you choose to email us a report.
- We don't sell your data or keep a profile of you.
Who we are
Mine Ace ("the app", "we", "us") is published by Ekspeace. Contact us at Ekspeace@gmail.com.
Mine Ace is an independent study aid. Its questions and model answers come from the Department of Mineral and Petroleum Resources (DMPR) Learners/Examiners Guides, but the app is not made, run or endorsed by the DMPR or any government entity, and it does not issue certificates.
What data is used, and why
| Data | Where it goes | Why |
|---|---|---|
| Your answers, progress, mock results, chosen certificate and settings | Stored only on your device | To schedule revision, show your readiness and mark mock exams |
| Advertising ID, device and app-usage information | Google AdMob | To show ads, including an optional rewarded ad for an ad-free day, and to prevent ad fraud |
| A problem report you choose to send: the question's ID, its text and where it is in the guide, and the app version, plus anything you type | Your own email app, then our inbox | To fix a question you tell us is wrong |
Reading questions aloud
Questions are read aloud by your phone's own text-to-speech engine. The app sends the question text to that engine on your device; it does not record your voice or listen to your answers.
Advertising
Mine Ace is free and funded by ads from Google AdMob. Google may collect and use device information and your advertising ID to show and measure ads, as described in Google's Privacy Policy and how Google uses information from apps that use its services.
Consent. Where the law requires it (for example in the EEA and UK), the app shows Google's consent message before any ads are requested, and a "Privacy choices for ads" option in Settings lets you change your choice at any time.
You can reset or delete your advertising ID, or opt out of personalised ads, in your phone's settings (Android: Settings > Privacy > Ads).
Links to other websites
Settings lists the official sources the app is written from (the DMPR website and its guides and directives). They open in your browser, and those websites' own privacy practices apply.
Young users
Mine Ace is made for mine workers preparing for a blasting certificate, for which candidates must be at least 20. It is not directed at children.
Keeping and deleting your data
- Data on your device stays until you use Settings > Reset study progress, clear the app's data, or uninstall.
- Emails you send us are kept only as long as needed to deal with your report.
- Data sent over the internet by the advertising SDK is encrypted in transit (HTTPS).
Your rights
Under South Africa's Protection of Personal Information Act (POPIA), and laws such as the GDPR where they apply, you may ask to access, correct or delete personal information, object to processing, or withdraw consent. Because we hold no accounts or profiles, most requests are handled by resetting or clearing the app's data, but you can always contact Ekspeace@gmail.com. You may also lodge a complaint with the Information Regulator.
Changes to this policy
If we change what the app does with data, we will update this page and the "Last updated" date above.
