Effective 30 September 2026.
This policy covers Ducky, Drip, Convert, Geometry Solver, MohrSolver, Toolbox and TriSolver, published by Wahlu Labs Pty Ltd.
Scores, game coins, settings, saved calculations and purchase-delivery records are stored on your device. We do not operate an account service or upload this data to our own servers. Removing an app can delete its local data. Apple may include app data in device backups according to your settings.
Ducky, Drip, Convert, MohrSolver, Toolbox and TriSolver use Google AdMob for small banner advertisements. Geometry Solver does not include advertising. The updated apps enforce Google Limited Ads, request non-personalized advertising, disable publisher personalization and publisher first-party identifiers, and do not request Apple's tracking permission. Limited Ads disables identifier-dependent features such as conversion tracking and frequency capping. Google may use limited local storage for fraud prevention.
Google's advertising SDK may process your IP address (including an approximate location), app/device identifiers, advertising interactions, product interactions, crash information, performance information and other technical diagnostics to deliver, measure and protect advertisements. This processing is carried out by Google; non-personalized advertisements still involve data processing.
Where applicable, Google's consent form allows you to choose how advertising data is processed. You can revisit the available choices through Ad privacy in the app's settings or Support page. If required consent or purchase verification is unavailable, advertising remains paused. Read Google's privacy policy and Google's SDK data disclosure.
Apple processes App Store payments. We do not receive your payment card details. StoreKit provides verified purchase records, which the app uses to unlock purchased content or deliver game coins. Remove Ads is a one-time purchase, with no recurring subscription. Existing eligible purchases remain restorable using the same Apple Account. Consumable coin packs are not restored as new coins; the app keeps a local delivery record to prevent duplicate credit. Verified refunds or revocations can remove access.
After ad-free access is verified, the app does not request banner ads. Use Restore purchases after reinstalling or changing devices.
Game Center is optional and operated by Apple; scores are sent to Apple when you choose to use the leaderboard. Toolbox uses camera and motion information for its measurement tools. That camera feed is processed on the device and is not sent to us or Google for measurement. Only use these tools where permitted and check measurements before relying on them.
You can turn game audio off, decline optional permissions, manage advertising privacy choices, buy ad-free access where offered, and delete locally stored data by deleting the app. For privacy questions or support, contact Wahlu Labs through wahlu.co. Apple's and Google's services have their own privacy policies.
