Hero Stroke — Privacy Policy

Last updated: 24 July 2026

Hero Stroke ("the app", "we") is a children's Chinese-learning app published by BoBo Design. This policy explains what information the app handles and why. We keep data collection to the minimum needed to run the app. We do not show ads, and we do not track you across other apps or websites.

Information we collect

When you sign in, we collect a small amount of account information so your learning progress and subscription can be tied to your account:

You can also use the app as a guest, without an account.

This information is used only to run the app — to sign you in, save progress, and manage your subscription. It is never used for advertising, and it is never sold or used to track you.

Microphone & speech recognition

To help your child practise reading characters aloud, the app uses the device microphone and Apple's speech recognition to check pronunciation in real time. We do not record, store, or send audio to our servers. You can revoke access anytime in iOS Settings › Hero Stroke.

Service providers

These providers process the data above only to deliver their part of the app. Learning progress and settings are otherwise stored on your device.

Children's privacy

Hero Stroke is designed for children. Because we show no ads, do no tracking, and collect only the minimal account data above, there is no profile of a child built for advertising or shared with data brokers.

Data retention & deletion

Account data is kept while your account is active. To delete your account and associated data, contact us at the email below and we will remove it.

Changes to this policy

If this policy changes, we will update the date above and post the new version here.
