Privacy Policy

Your family’s app data stays on your device

Lucky Math stores its app data locally on your device. This includes:

• Child profiles, profile names, and selected avatars.
• Learning progress, quiz results, streaks, and earned badges.
• Math difficulty levels and selected operations.
• Custom rewards, quantities, assignments, and prize history.
• Quiz settings, reward probabilities, and passcodes.

This information supports personalized quizzes, tracks progress, and lets parents manage rewards. We do not receive this data or sync it to our servers. Lucky Math does not require an account.

Children’s privacy and parent controls

Lucky Math is designed for children to use with parent or guardian involvement. Children’s profile information and learning activity remain on the device and are not collected by us through the app. A nickname can be used for a child’s profile instead of a full name.

Parents choose the rewards and learning settings. The parent area is protected by a passcode, and individual profiles can have optional passcodes. These controls help manage access within the app; please also use your device’s security settings to protect access to the device itself.

Anonymous usage analytics

Lucky Math uses TelemetryDeck, a privacy-focused analytics service based in Germany, to understand how the app is used and improve it. TelemetryDeck receives anonymous usage events such as which setup screens are viewed, which Lucky Math Plus option is selected, and how rounds go (for example, when a round finishes or a high score is reached).

We never send names, ages, answers, or anything typed into the app. TelemetryDeck uses only a one-way hash to distinguish a device; it does not identify a person. We use this information only to improve Lucky Math. It is not used for advertising or tracking, and it is not sold.

In the App Store privacy label, this is described as Device ID and Product Interaction data used for Analytics. Neither item is linked to you or used to track you across apps or websites.

Lucky Math Plus, subscriptions, and free trials

Lucky Math Plus may be available as a one-time purchase or as a monthly subscription with a 3-day free trial. Apple processes all payments, so we never receive or store your card or other payment details.

You can manage or cancel a subscription in your iPhone's Settings. If you start a free trial, Lucky Math can show a reminder notification on your phone the day before it ends. The reminder is created and kept on your device; no reminder information is sent to our servers.

Family sharing by invite link

Parents can join a family by pasting an invite link. Information shared with a family remains in the members' own iCloud accounts through Apple CloudKit. We cannot read that shared information.

Keeping and deleting your data

Local app data remains on your device until it is removed. To remove all local Lucky Math data, use your device’s app-data controls or delete the app and its data. Offloading an app may keep its data. We cannot access or delete locally stored data on your behalf.

Your operating system may include app data in device backups, depending on your settings. These backups are separate from Lucky Math and are managed by your device or backup provider. Review your backup settings to manage or delete those copies.

When you contact us

If you email us, we receive your email address and the information you choose to include. We use that information to respond to your request and provide support. Please have a parent or guardian contact us, and avoid including children’s personal information, passcodes, or other sensitive details that are not needed to explain the issue.

You can contact us to request deletion of your support correspondence.

Changes to this policy

We may update this policy as Lucky Math changes. The latest version will be available on this page.
