1. Scope and provider
This policy applies to the WordLens iOS app and related user support provided by InfEngine Labs (苏州工业园区无限引擎软件开发工作室).
2. On-device processing
OCR, dictionary lookup, pronunciation preferences, vocabulary books, review, dictation, spelling, and learning statistics are primarily handled on your device. WordLens requires no account and does not upload this content to an InfEngine Labs server.
3. Photos and scan history
WordLens accesses the camera or a selected photo only when you choose to capture or import an image. High-resolution source images are removed after processing. Compressed scans, recognized text, and word boxes are stored on your device to restore scan history until you delete the record or erase the data.
4. Google ML Kit
WordLens uses Google ML Kit Text Recognition to recognize text on device. Google states that input images, text, and recognition output are not sent to Google servers.
ML Kit may still contact Google for bug fixes, model updates, and hardware compatibility information. It may send device and application information, installation-scoped identifiers, performance metrics, API configuration, event types, and error codes for diagnostics, usage analytics, maintenance, and abuse prevention. Google processes this data under its privacy policy.
5. App Store purchases
Apple App Store handles optional WordLens Pro purchases, restoration, refunds, and revocations. WordLens receives product and entitlement status from the store to decide whether Pro is unlocked. InfEngine Labs does not receive your full payment-card information or Apple account password.
6. System backup and export
If you enable iCloud Backup, the operating system may back up app data under your Apple settings. WordLens does not perform that upload itself.
You may export a .wordlens backup. It contains vocabulary and learning records, does not contain scan images or purchase credentials, and is not encrypted. After export, the location or sharing destination you choose is responsible for storing it.
7. Support email
When you email support, we receive your email address, message, and anything you choose to attach. We use it to reply, investigate the issue, and retain necessary support records. We keep it only as long as needed for those purposes and applicable legal obligations. Do not send passwords, verification codes, or full payment information.
8. Your controls
You can delete individual records, clear scan images, or erase all user data in the app. You may also contact us to ask about or request deletion of personal information in support correspondence, except where applicable law requires retention.
9. Children and minors
WordLens does not use accounts, advertising, or app-operated analytics to solicit children's personal information. A minor who needs to contact us should do so with a parent or guardian where local law requires it.
10. Security, changes, and contact
We reduce risk by limiting data and favoring on-device processing, but no device, backup, or electronic communication can be guaranteed absolutely secure.
If features or data practices materially change, we will update this policy and its effective date. Email privacy questions to support@infenginelabs.com.
