This policy explains what data EarCraft collects, how it is used, and your rights as a user.
Last updated: October 22, 2026 · Effective: October 22, 2026EarCraft: Ear Training ("we", "us", "our") is developed and operated by Beijing Yijing Technology Co., Ltd. We are committed to protecting your personal information and being transparent about what we collect and why.
This Privacy Policy applies to the EarCraft app available on the Apple App Store and Google Play, and to any related services we provide.
When you create an account, we collect the information needed to identify you and provide the service:
To deliver a personalized training experience, we store:
This data is tied to your account and synchronized across your devices.
Purchases are processed entirely by Apple App Store or Google Play. We do not receive or store your payment card information. We do store:
If you participate in leaderboards, your nickname and ranking score are visible to other users. You can change your nickname at any time from your profile settings.
We may collect limited technical information to maintain and improve the service, such as app version, device type, and operating system version. Some usage records can be associated with an installation or signed-in account; these records are not necessarily anonymous.
Hosting and network providers may process connection metadata, including IP addresses, under their own policies.
Usage statistics: our existing Supabase statistics use a random installation identifier, activity date and module, and the verified account identifier when signed in. They may be linked to registration and validated purchase records to measure activity, retention and conversion. We do not use advertising identifiers or device fingerprints, upload raw recordings or answer content for these statistics, or use them for advertising or cross-app tracking.
We do not sell your personal data to third parties. We do not use your data for advertising purposes.
Your data is stored securely on Supabase infrastructure. All data in transit is encrypted using HTTPS/TLS. We apply access controls to limit who can access your data within our systems.
We retain account and synced learning records for service delivery. Successful in-app deletion processes supported account records during that request. For support-assisted requests, 30 days after ownership verification is a manual processing target, not an automatic expiry or guaranteed completion time. Necessary financial, fraud-prevention or legal records may be retained for the applicable purpose and period. Guest and installation statistics have no automatic 30-day deletion schedule. Account deletion does not guarantee removal of third-party records or cached data on every device. See the account deletion instructions for scope, verification and subscription cancellation.
EarCraft uses the following third-party services that may handle data on our behalf:
Each service operates under its own privacy policy. We encourage you to review them.

To exercise any of these rights, contact us at MusicLabFun@163.com. You can request deletion in the app or without installing or signing in to the app. We verify account ownership before acting.
EarCraft is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us immediately at MusicLabFun@163.com and we will promptly delete it.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Continued use of EarCraft after changes constitutes acceptance of the updated policy.
