PDF理顺PDFTidyPrivacy policy
This policy is provided by individual developer luojunyin for the current iPhone version of PDF理顺PDFTidy and this support website. Contact: junyin686@gmail.com.
1. PDFs, images and scans
The app uses PDFs and images you select and scanned pages you confirm to merge, organize, split, export images, add watermarks or page numbers, crop, fit paper and optionally compress on your device. The current app has no feature that uploads this file content to a developer-operated server. No app account registration is required.
Paper scanning uses the system camera and Apple document-scanning features only when you initiate it. You may deny camera permission, cancel a scan or use file/image import instead. The app does not continuously capture in the background or automatically publish scans to a developer service.
2. Local state and temporary copies
The current workspace, previews and undo history serve the current session. Recovery of unsaved work after exit or system termination is not promised. Save a separate copy of results you want to keep.
Before saving or sharing, the app creates a copy in its dedicated local temporary directory for the system panel. It does not intentionally remove the copy while that panel is using it. On the next launch, the app attempts to clear this dedicated directory; the system may also reclaim caches. This cleanup does not target your input originals or copies saved elsewhere.
iCloud Drive, photo services, third-party file providers, system backups and share destinations may download, synchronize, back up or transmit data under their own settings and policies. Local processing does not mean every system service you choose is offline.
3. Apple trial, purchases and restoration
The seven-day trial, one-time unlock and purchase restoration use Apple StoreKit. Apple handles payment and transaction verification; these operations may connect to Apple services. The app does not receive your Apple Account password or payment-card details.
The app reads verified transactions, original purchase time, revocation status and an app-specific purchasing-account scope identifier. It stores local verification markers and observed time to determine access, prevent restarting a trial and handle account changes. This information is not used for advertising or cross-app tracking and is not uploaded by the current app to a developer-operated server.
Deleting the app does not delete Apple's transaction records or create a new trial entitlement. Purchases, refunds and Apple's data handling follow Apple's service rules. See Apple's privacy policy.
4. Analytics and system components
The current app has no advertising, third-party analytics or SDK that automatically uploads documents or diagnostic data to the developer. PDF, image, font and scanning features primarily use Apple system components; compression runs locally. Apple and system diagnostics or services follow the relevant system settings and policies.
5. Website and email support
This is a static information website. It has no file-upload form, sign-in, online payment or analytics script, and does not intentionally set tracking cookies. Alibaba Cloud provides the hosting infrastructure. The developer and hosting provider may process request paths, IP addresses, timestamps and browser information to deliver and protect the service, subject to the actual configuration and privacy rules.
If you email support, your email address, message and attachments are handled by the email service and developer to respond, investigate and follow up. Correspondence is retained for the period needed to handle the request and necessary obligations. Prefer steps and non-sensitive samples; you do not need to send identity documents or complete private PDFs. Contact the address above to ask about access to or deletion of support correspondence.
6. Your choices
You may decline scanning, manage permissions, avoid sharing, and manage or delete saved copies in your device and file services. Removing the app can remove its local application data; externally saved files and Apple's transaction records must be managed separately. The developer cannot remotely read or delete your local PDFs.
We will update this page and its date if the policy or data handling changes materially. Questions can be sent to junyin686@gmail.com.
