SimpleMath Privacy Policy

Last updated: August 30, 2026

Overview

SimpleMath is a bilingual elementary-math learning app. LIPAI WANG designed it so that learners can use its core learning features without creating an account or providing personal information to us.

Information and learning progress

SimpleMath stores an optional learner display name, language and theme choices, learning progress, wrong-answer topics, stars, streaks, and stickers on the device only. This information is used solely to provide the App's features. It is not transmitted to LIPAI WANG, advertisers, analytics providers, or other third parties.

What we do not do

• We do not collect, sell, share, or track personal data.
• We do not use advertising, third-party analytics, or accounts.
• Optional Premium purchases are processed by Apple through StoreKit on iOS and Google through Google Play Billing on Android. SimpleMath does not receive or store payment-card information.
• We do not make network requests as part of the App's learning experience. The applicable store service is contacted only when a parent chooses to load, restore, buy, or manage a purchase.

Children's privacy

SimpleMath is designed for young learners. Because learning data remains on the device and is not sent to us, we do not knowingly collect personal information from children.

Your choices

You can remove the optional display name or change settings from within the App. On Android, the parent panel also includes an Erase on-device learning data control. Clearing app storage or deleting SimpleMath removes the learning data stored on that device, subject to the device's normal backup settings.

Changes to this policy

If this policy changes, we will update this page and its “Last updated” date before the change takes effect.
