Abacus Quest: Learn & Master ("the app", package com.abacusquest) collects no personal information. It is made by Vishal Talekar ("we", "us") for children, and is built to handle as little data as possible.
This policy covers the Android app, version 1.0.0 and later. It takes effect on 25 September 2026.
We collect no personal information. The app has no accounts, sign-in or chat. There is nowhere to enter a name, email, photo or location. We run no servers, and nothing is sent to us.
Progress (high score, rank, stars, finished lessons): stored only on the device, shared with no one.
Settings (Kid Mode, sound, music, ads removed): stored only on the device, shared with no one.
Technical data for ads (device model, OS version, app ID, IP address): sent by the ad SDK to Google AdMob.
Remove Ads purchase status: held by Google Play.
The app uses standard Android permissions for internet access, Google Play purchases, and those required by the Google ads library. It does not use the camera, microphone, contacts, location or the advertising ID.
On-device data is used only to run the game: keep your place, show your score and remember your settings.
Ads. The free version shows a banner and an optional rewarded video from Google AdMob. Ads never appear during a lesson or round, or when the app opens. The rewarded video is offered only after a round, and in Kid Mode it sits behind a grown-up check.
Purchases. The optional Remove Ads purchase is handled entirely by Google Play. We never see payment details. Google Play tells the app only whether you own the purchase, so it can be restored on reinstall or a new device.
Grown-up check. Purchases and links out of the app always require an adult to pass a check first; in Kid Mode, so does the optional video.
Two Google services receive data from the app. Each handles it under its own policy.
Google AdMob shows and counts ads and prevents fraud. It receives the device model, OS version, app ID and IP address (which may indicate approximate location). Policy: https://policies.google.com/technologies/partner-sites
Google Play Billing processes and restores the Remove Ads purchase. It receives the purchase record on your Google account. Policy: https://policies.google.com/privacy
Every ad request is marked child-directed (COPPA) and under the age of consent (GDPR), limited to G-rated content, and flagged non-personalised. This turns off personalised ads and remarketing.
The app is made for children and follows Google Play's Families policy. We do not knowingly collect personal information from anyone, including children under 13.
If you believe a child's personal information has reached us, email us and we will delete it.
Progress and settings stay on the device until you delete them. They are not backed up to the cloud.
Reset: Settings ▸ Reset all progress erases everything at once.
Uninstall: removing the app deletes all its data.
Google data: manage what Google holds in your device's Google settings or at Google Privacy Policy.
We hold no personal information about you, so there is nothing for us to access, correct or delete.
If this policy changes, we will post the new version at the same address and update the date at the top. The app's Settings ▸ Privacy policy button always links to the current version.
