About this policy
Additional Maths is developed by Roland for learners aged 13 and above. This policy describes the Android app. Last updated: 26 October 2026.
Learning information and classroom identity
You provide a display name before entering the classroom. Lesson progress, selected answers, saved questions, written reasoning, reflections and investigation notes are saved on your device. The app uses Firebase anonymous sign-in to identify this installation for online features. Do not enter sensitive personal information in your display name or notes.
Daily challenges and leaderboard
Daily challenge answers and recent scores are saved on your device. After a challenge, the app sends your anonymous learner identifier, display name, date, week number and points to Google Firebase Cloud Firestore. Other learners using the app can see display names and points on that day's leaderboard. Ordinary practice answers and lesson notes are not sent to the leaderboard. Google Firebase may process technical information needed to run and protect this service.
Learning mates
While you are in a lesson, the app sends your anonymous learner identifier, display name, week, subtopic, recent activity time and whether you finished that subtopic to Google Firebase Cloud Firestore. Learners in the same subtopic can see the names of recently active learners and learners marked as finished. “Online” means active in the last two minutes; this is not a live chat or video connection.
Advertising
The Android app uses Google AdMob to support free lessons. It requests non-personalised ads and displays a banner on the home screen. The Google Mobile Ads SDK may collect or share IP address, approximate location inferred from it, ad interactions, diagnostics and device or account identifiers for advertising, measurement and fraud prevention. Non-personalised ads do not mean that no data is processed. Google handles its data under its privacy policy.
Advertising privacy choices
The Home banner may load after privacy checks. No age selection is required. Ad requests use restricted teen treatment, a general-audience content filter and disabled personalisation. Google consent options are requested before ads initialise, and any required form is shown. Available privacy options can be reopened in Settings. Earlier under-13 choices keep ads off. Lessons remain available when ads cannot load.
External videos
Video buttons open a YouTube topic search outside the app. YouTube and your browser may process information under their own policies. Answers and notes are not added to the search links. Results are not individually reviewed by Roland.
Support messages
If you email support, Roland receives your email address and the information you include to respond and resolve the issue. Do not send passwords or unnecessary personal details. You may request deletion of support messages.
Retention and deletion
Local learning records remain until you reset progress, clear the app's storage or uninstall it, subject to your device's behaviour. Daily challenge history is stored separately on the device. Resetting progress does not delete leaderboard scores or lesson presence already sent to Firebase, information processed by Google, or support emails. Contact support to request removal of your online records. Earlier advertising privacy settings are preserved when learning progress is reset.
Permissions and security
The app does not request camera, microphone, contacts or precise location access for learning. Google ad requests use internet access and applicable identifiers. Protect your device because someone with access to it may read saved notes. No storage or transmission method is guaranteed completely secure.
Policy updates
This policy may change as app features change. The updated date and policy will be available here and in the app.
