Who we are
Easy Lecture: Voice Notes is published by Xianzhuo Intelligent Technology (Shanghai) Co., Ltd.. Contact: hi@xianzhuo-ai.com. Last updated September 20, 2026.
Your recordings and notes
Recordings, transcripts, photos, annotations, course information and review data are stored in the app on your device. Apple on-device speech recognition is used where supported. We do not send lecture audio to a developer-operated transcription server. Recognition availability depends on device, language and installed system resources; downloading resources may require an internet connection. Transcripts may contain errors.
Optional iCloud sync
Sync is off by default. If you enable it, library content, including audio and photos, is transferred through Apple CloudKit to your private iCloud database for your devices using the same Apple Account. Apple operates iCloud. Turning sync off stops future sync but does not erase existing cloud or other-device copies.
Purchases
Apple processes payments, trial eligibility and renewals. The app reads verified transaction and entitlement information to determine subscription access. We do not receive full payment-card details through the app. Restoring purchases restores eligible subscription access, not recordings or notes.
Permissions and sharing
Microphone and speech recognition access support recording and transcription. Camera and photo access support adding images when requested by the relevant feature. You can change permissions in system settings. Exports go to destinations you select; recipients and other services control their copies. Device backups may contain app data according to your settings.
Retention and deletion
You control records stored in the app. Recoverable deletion may retain content in Recently Deleted until permanently removed. Removing a sentence or annotation does not necessarily remove original audio, independent exports or other content. When sync is enabled, deletion changes can propagate to other devices, but historical cloud assets, shared copies and backups are not necessarily erased immediately. Disabling sync or uninstalling the app is not a request to delete every cloud copy. Contact us for guidance before deleting important material.
Support and diagnostics
If you contact support, we receive your email address, message and attachments and use them to respond and investigate. Please share only information needed for support. We keep support correspondence as needed to resolve the request and meet applicable obligations; contact us to request its deletion. Apple may provide diagnostics or TestFlight feedback according to your choices and its services. These may include crash information and information you submit.
Advertising and this website
We do not sell lecture content or use it for targeted advertising. These pages contain no advertising or analytics scripts. Your hosting and email providers may process technical connection and delivery data according to their own policies.
Your choices and updates
You can change permissions, disable sync, manage or export local content, and contact us about privacy or support correspondence. Do not record or share other people without the permissions required in your situation. We will update this policy when our practices change.
