Paperix is a document-scanning app for iPhone and iPad. This page describes what data Paperix handles and what it does with it. The short version: it doesn't handle any of your data anywhere outside your device.
What Paperix collects
Nothing. Paperix has no network code, no accounts, no analytics, no crash-reporting SDK, and no advertising identifiers. The compiled application binary does not contain code that can transmit data over the internet.
Where your scans live
Scans are saved as PDF files in the app's Documents folder on your device. They are not synced, uploaded, or transmitted anywhere by Paperix. If you choose to share a scan via the iOS share sheet — to Mail, Messages, AirDrop, Files, iCloud Drive, or any other destination — that destination's privacy policy governs what happens to the file from that point forward.
If you have iCloud Backup enabled at the system level, your scans may be included in your encrypted iCloud Backup. That is governed by Apple's privacy policy, not ours.
Camera and photo access
Paperix requests camera access to capture documents. The camera permission is used only while you are actively scanning, and frames are processed on-device by Apple's Vision framework.
Paperix may request "Add to Photos" permission when you choose to save a PDF to your Photo Library. Paperix does not request "Read Photos" access — it never reads your photo library.
On-device text recognition
After each scan, Paperix runs Apple's on-device text recognition
(VNRecognizeTextRequest) so the resulting PDFs are searchable.
The recognized text is embedded inside the PDF file as an invisible text
layer and is stored only with the PDF. No text is transmitted anywhere.
On-device AI (Analyze and Ask Paperix)
Paperix offers AI features — summarization, key points, follow-up questions about a document, and a cross-document "Ask Paperix" surface that returns answers with citations. Every step runs on your device using Apple's Foundation Models framework (large language model) and the Natural Language framework (embeddings). Both execute on the Neural Engine. No document content, embedding, query, or model output is transmitted off the device, ever.
Paperix maintains a small index of embedding vectors for your documents inside the app's Documents folder so questions can be answered quickly without re-processing every scan on every launch. This index is local-only and lives next to your scans.
AI features require Apple Intelligence, which is supported on iPhone 15 Pro and later, and on iPad with M-series chips. On older devices the AI features are simply hidden and the rest of Paperix works the same.
Children
Paperix is rated 4+. It does not collect any information from anyone, so it does not collect information from children either.
Changes
If a future version of Paperix ever adds a feature that requires network access (for example, optional iCloud sync), this policy will be updated and the App Store listing will say so clearly. Existing local data will remain local unless you opt in.
