Privacy Policy — Drip Chinese

Effective date: September 22, 2026.

1. Who we are

Hangzhou Guanheng Technology Co., Ltd (杭州观恒科技有限公司) provides Drip Chinese. This policy describes the app, its website and support email. Contact hi@dripchinese.com with privacy questions or requests.

2. Information used by the app

The app stores your learning settings, selected word packs, daily plans, learning progress, answers, practice state and actions such as marking a word known or resuming reviews. It also stores technical identifiers, timestamps and content-version references needed to save, restore and reconcile that learning correctly. Onboarding drafts and navigation state are stored locally.

The app and its widgets share local storage to display your daily words and progress. The bundled vocabulary, audio and glyphs are learning content, not recordings of you. Pronunciation playback does not require recording your voice.

3. iCloud

When available, supported learning information and confirmed settings synchronize automatically through Apple's iCloud service, using a private CloudKit database. This includes the learning and plan information needed to resume and combine progress across your devices. The app uses an iCloud account identifier to keep different accounts' local data and pending changes separate; it does not ask for your Apple Account password.

Local navigation, unconfirmed onboarding input, widget display position and rating-request history are not part of this synchronization. Bundled learning content is not uploaded as your progress. iCloud processing is also subject to Apple's Privacy Policy.

Network interruptions, account restrictions or insufficient iCloud storage can delay synchronization. Local learning can continue. Signing out of iCloud is not a request to erase the local copy.

4. Purchases

Apple processes purchases. The app uses verified purchase and subscription information, such as the product, transaction identifiers, validity dates and entitlement status, to provide Premium access and restore purchases. We do not receive your payment-card number. Premium purchase state is verified with Apple rather than synchronized as learning data through our iCloud records.

5. Ratings, diagnostics and support

To avoid repeatedly interrupting you, the app keeps a local record of distinct completion days and when it requests an App Store review. This record is not uploaded by the app and is excluded from its backup. The app does not know whether you submitted a rating. An optional rating or review is handled by Apple.

The current app contains no advertising or third-party behavioral-analytics SDK. Limited technical diagnostics, such as an error category and code, may be written to device system logs. Our synchronization diagnostics do not include account identifiers or learning content. Apple's own diagnostics and any information you elect to share through Apple's services are governed by its settings and policies.

If you email us, we receive your email address, message and any attachments you choose to send. We use Feishu Mail to receive, store and respond to support correspondence, resolve reported problems and handle requests, not for marketing. Access is limited to people who need it to handle support. We do not configure automatic forwarding, mail archiving, AI processing or third-party customer-support integrations for this mailbox. Do not send passwords, full payment-card details or unrelated sensitive information.

6. Retention and deletion

Local learning records are retained to support your learning history. You can remove the app to remove its app installation data; shared widget storage and device backups are managed by iOS. Removing the app does not itself delete iCloud data, Apple purchase records or emails already sent to us.

You can manage Drip Chinese's iCloud data using Apple's iCloud storage controls. When the app detects deletion of its cloud data, it retains your local learning and pauses automatic recreation. Choosing Resume iCloud Sync and confirming it uploads local learning again. If your aim is permanent removal, remove relevant local copies and manage iCloud data and backups as well; contact us if you need guidance. We do not promise deletion of Apple's independent purchase or service records.

We delete ordinary support correspondence no later than 12 months after the request is closed. Records needed for a legal obligation or an unresolved dispute may be retained for as long as necessary for that purpose. You may contact us to request earlier deletion, subject to applicable requirements. This schedule applies to support records we control; it is not a promise of immediate removal from a provider's backups or independent security records.

7. Your choices and rights

Depending on where you live, you may have rights to access, correct, delete or obtain information about personal data, or to raise a complaint with a supervisory authority. Contact hi@dripchinese.com. We will respond in accordance with applicable law. Apple-managed information may also require a request through Apple. The app does not currently offer a general data-export feature.

Drip Chinese is intended for adult learners, not a service directed to children. Contact us if you believe a child has sent us personal information.

8. Website and service providers

Our website is hosted on Cloudflare Workers. We do not configure website access logging, advertising or visitor-analytics tools, or set cookies in our website code. We have not enabled Turnstile or optional bot-protection features. Cloudflare may still process necessary network information, such as IP addresses and request information, to deliver and secure the website. Disabling our own logging does not mean that infrastructure providers process no data. See Cloudflare's Privacy Policy.

Apple, Feishu and Cloudflare process information in connection with the respective services described above. Our company operates in China, and support correspondence is handled by our team there. Depending on the service and its configuration, processing may occur outside your country. We do not promise that all app, email and website information stays in a single country.

9. Updates

We will display the effective date of each policy revision. Material changes will be communicated where required by law.
