About this policy
This policy covers the Android app NZ Driving Test Theory (“the app”), published by Tech Dunya (“we”, “us”). The app is an independent study tool for people preparing for the New Zealand driver licence theory test. It is not affiliated with NZ Transport Agency Waka Kotahi (NZTA) or any government agency.
No account, no server
You do not need an account. We do not ask for your name, email address, phone number or precise location, and we do not run a server that receives your study data.
What is stored only on your device
Your selected vehicle type and language, quiz answers, scores, mistakes, statistics, bookmarks, checklist ticks, completed lessons, settings, and the timer for the optional ad-free hour. We do not receive or see this data.
Advertising (Google AdMob)
The app is free and shows ads (banner, native, full-screen and an optional rewarded video) served by Google AdMob. AdMob and its partners may collect and use your advertising ID, IP address (which gives approximate location), device and operating-system details, app information and your interactions with ads, to deliver, measure and personalise ads and to prevent fraud. We do not receive your personal data from AdMob. Google’s policy applies to that data: https://policies.google.com/technologies/ads
Consent and your choices
Where the law requires it (for example the EEA, UK and some US states), the app shows a Google consent message before personalised ads. You can open it again in the app at Settings → Privacy choices (ads). You can also reset your advertising ID or opt out of ad personalisation in Android Settings → Privacy → Ads.
Voice read-aloud
If you use read-aloud, the app uses the text-to-speech engine already on your device (for example Google Text-to-Speech). We do not send this text to ourselves. That engine’s provider handles its own data.
Links
The app has a link to the NZTA driver licences page, and links to this policy and to our support email. Those open in your browser or email app, and the other site’s own policy applies.
Children
The app is intended for people aged 16 and over (learner-licence age in New Zealand). It is not directed at children under 13, and we do not knowingly collect their personal information. If you believe a child has provided information, contact us.
Retention and deletion
Study data stays on your device until you delete it or uninstall the app. Use Settings → Reset my progress to delete it inside the app. If Android backup is on, Google may back up app data to your Google Account under your device settings. We keep no personal information on our own servers, so we have nothing to delete there. For data held by Google, use your Google Account controls.
What we do not do
We do not sell or rent personal information. The app has no in-app purchases and collects no payment details.
Security
Data sent to Google services is encrypted in transit.
Changes
We will post changes on this page and update the date below.
