VocabularyStream Privacy Policy

View the Chinese version

This Privacy Policy explains how VocabularyStream handles information when you use the App.

1. Information the App uses

The App stores learning settings, selected vocabulary lists, learning progress, and downloaded vocabulary-cache files locally on your device. The App does not provide a developer-operated account, login, or server-side profile, and it does not upload your learning progress to the developer.

To refresh learning content, the App can download public vocabulary manifests and vocabulary files over HTTPS. Network providers may necessarily process ordinary connection data such as IP address and request logs to deliver that connection.

2. Purchases

Optional annual auto-renewable subscriptions and lifetime non-consumable purchases are processed by Apple through StoreKit. Apple shows the product, price, currency, applicable renewal period, and payment information before purchase. Lifetime purchases do not renew. The developer does not receive or store your payment-card number or Apple Account password. Apple handles payment, renewals, cancellations, refunds, and purchase restoration under its own policies.

3. No advertising or behavioral tracking

The App does not include advertising, third-party advertising SDKs, behavioral tracking, or analytics SDKs. It does not sell personal information.

4. Sharing and retention

Because learning data is stored locally and is not uploaded to the developer, the developer does not share it with third parties. You can remove local App data by deleting the App or using applicable device settings. Apple may retain purchase records according to Apple's policies.

5. Children and age

The App is a general vocabulary-learning product and does not knowingly create developer-operated accounts for children. Users and, where applicable, parents or guardians should use the App and make purchase decisions in accordance with applicable law.

6. Changes and contact

We may update this policy when the App or applicable requirements change. For privacy questions, contact sunny8060@foxmail.com.
