Privacy Policy
At a glance: scans and images are processed on your device. We do not upload them, require an account, or include advertising or behavioral analytics SDKs. System backups, sharing, Apple purchases and website access are described below.
This policy applies to the PaperIn iOS app and this website. It distinguishes data processed locally, information you choose to send, and access logs generated when this website serves a request.
1. On-device processing and collection
Scanned and imported images, document names, page order, crop and filter settings, and exported PDFs and images are processed and stored on your device. We do not receive or store these documents on our servers, offer app accounts or developer-operated cloud sync, or send documents to AI providers.
Export preferences such as format, paper size and quality are stored locally. The current app has no third-party advertising, behavioral analytics or crash-reporting SDKs, does not access IDFA, and does not track you across apps. Diagnostic sharing by your device or the App Store is controlled by Apple settings. Apple may provide developers with diagnostic or aggregate reports; this is separate from installing a tracking SDK in our app.
2. System permissions
- Camera: used when you start scanning to create document pages. We do not continuously record in the background or upload the camera feed.
- Photo selection: the system picker imports only the photos you select, without requesting access to your entire library.
- Add to Photos: the app requests add-only permission when you save exported images to Photos.
- Files and sharing: system interfaces send your chosen files to the location or app you select.
You can revoke permissions in iOS Settings. Without camera access you can still import photos. Without add-to-Photos access you can still save to Files or use other export options.
3. Storage, backups and deletion
Documents are kept in the app’s local storage. You can delete documents or pages in the app. Deleting the app normally removes its local documents; iOS “Offload App”, which keeps data, is different from deleting it. Copies exported to Photos, Files, cloud providers or other apps must be deleted separately at those destinations.
App data may be included in iCloud or computer backups that you enable. These are Apple or user-chosen system backup services, not cloud sync operated by us. Backup copies and restoration depend on those services and your settings. We cannot access your local files or delete third-party copies. Export and back up important documents.
4. Purchases and third-party services
If your App Store version offers in-app purchases, Apple handles payment, refunds and Apple account information. The app may use StoreKit to read transactions or purchase entitlements on your device for unlocking and restoring features. We do not receive your Apple account password or bank card details. Actual pricing and entitlements are shown on the purchase screen.
When you choose to share, save to a third-party cloud provider, or open an external website, the recipient handles the selected content under its own policy. We do not sell or provide scanned documents to third parties except for your chosen action, legal requirements or separately obtained valid authorization. Apple services are governed by Apple’s Privacy Policy.
5. Website visits and contacting us
Local scanning and exporting do not require visiting this website. When you visit the download or policy pages, the web server processes standard access logs, including IP address, request time, path, HTTP status, transfer size and browser information, to serve pages, troubleshoot problems and maintain security. Logs are retained only as needed for service delivery, security and legal duties, with restricted access and periodic deletion.
This website has no advertising or third-party analytics scripts, uses no tracking cookies, and does not ask you to upload documents. Language is selected through paths or link parameters. If you email us, we process the email address, description and attachments you provide only to handle the request and necessary follow-up. Please redact sensitive content first.
6. Your choices and rights
You can manage permissions, view and delete local documents, control system backups and choose sharing recipients. There is no app account to close.
For information you email us and identifiable website access data, you may request access, correction, deletion, restriction or object to processing under applicable law. Where applicable you may withdraw consent, request a data copy or complain to a competent supervisory authority. Contact us below. We respond within applicable legal time limits and request only reasonable information needed to verify the request. Your local documents are under your control; we cannot retrieve or restore them from a server.
7. Minors, security and updates
Minors should use the app with a parent or guardian’s guidance and avoid sending sensitive information about themselves or others. A guardian who believes a child provided personal information in feedback can contact us for assistance.
We use access controls and transport safeguards appropriate to the information we process. Protect your device with a passcode and keep exported files secure. No storage or transmission method is completely secure. If we introduce new data processing, we will update this policy and provide notice or obtain consent where legally required.
