Subscriptions
Why am I seeing a subscription screen?
Creating documents and using related tools requires an active subscription. Available plans, such as weekly, quarterly, and annual subscriptions, appear on the current subscription screen. Prices, currencies, billing periods, and applicable trial or offer details come from Apple and are confirmed on Apple's purchase screen. Closing the first screen at the top right opens a second subscription screen. Close that screen to return without buying.
What if prices cannot load?
Tap Retry on the subscription screen to reload plans. The app displays only currently available plans with Apple product information. If no plan is available, the purchase button is disabled. A free trial appears only when you qualify for the current product; its duration appears in the app and on Apple's confirmation screen.
How do I restore purchases?
Use the original purchasing Apple Account and tap Restore Purchases at the bottom of the subscription screen. Retry later if Apple or the network is delayed. Complete any pending purchase approval first.
How do I cancel or request a refund?
Open Settings → Apple Account → Subscriptions and cancel at least 24 hours before the current period or trial ends. Uninstalling does not cancel. Apply for refunds through Apple, which handles the request.
Files and tools
Where are files saved?
Files are stored in the app's local Documents directory. Manage or export them in My Files or the system Files app. Back up before deleting files or uninstalling. A subscription does not include cloud document backup.
What editing is supported?
Create Word, Excel, PPT, and PDF documents and edit built-in templates. The XLSX editor supports basic cells, formulas, charts, and pivot summaries within its stated limits. Advanced features are preserved where supported and may require Excel to recalculate. Use a desktop editor for complex layouts, animations, or macros, and check saved output.
Why does conversion need internet?
Complex Office/PDF conversion uses our backend and CloudConvert. Only files you select and submit are uploaded. Maximum file size is 50 MB. Connectivity, quotas, and compatibility can affect results. OCR and common PDF tools run locally.
Do OCR or scanning upload images?
No. OCR uses Apple Vision on your device. Scanning uses Apple VisionKit and a camera on a physical device, saving a local PDF.
What if formatting changes or conversion fails?
Check connectivity, file format, and size. Keep the original and try again. Fonts, formulas, macros, animations, and special layouts may have compatibility differences. Review the output.
Language
Open Profile → Preferences → App Language to choose Follow System, Simplified Chinese, or English. Other system languages use English. Switching language does not translate or rename existing documents. On-device OCR supports Chinese and English.
Privacy choices
Profile → Privacy and Security controls Basic Analytics and Ad Attribution. These are optional and off by default for new users. Existing choices are retained. Umeng is enabled only with your permission and a confirmed mainland China App Store storefront or domestic region; it is not initialized and does not report data for overseas or unconfirmed regions. Apple ad attribution runs independently. Turning these services off, reporting failures, or timeouts do not affect documents, subscriptions, or navigation. Contact us to request deletion of previously uploaded data. See the Privacy Policy and Terms of Use.
