Privacy Policy for PDFix

Last updated: July 25, 2026

PDFix ("the App", "we", "us") is a document scanning application published by ydev. This Privacy Policy explains what data the App collects, how it is used, and the choices you have.

Summary

Your documents, scans, and photos are processed and stored on your device. We do not upload, view, or store the content of your documents on any server.
Text recognition (OCR) runs entirely on-device. No image or text ever leaves your phone for this feature.
We use Firebase Analytics and RevenueCat to understand app usage and manage subscriptions. Neither receives your document content.
We do not require account creation, and we do not collect your name, email, or contact list.

Data We Collect

1. Content you create (documents, scans, signatures)

Scanned pages, imported photos, generated PDFs, and signatures you draw are stored locally in the App's storage on your device (and in your device backups, if you have iCloud/Google backup enabled at the OS level). We do not have access to this content and it is never transmitted to our servers.

2. Camera and Photo Library

The App requests camera access to scan documents and photo library access to import existing images or save finished scans. These permissions are used only to let you choose what to scan or save — no image is sent anywhere without your action (e.g., tapping "Share").

3. Text recognition (OCR)

OCR is performed using Google ML Kit's on-device text recognition model. Images and extracted text are processed locally and are not sent to Google or any other third party for this feature.

4. QR code scanning

The QR scanner reads codes using your camera in real time. Scanned QR content is shown to you in the App and is not transmitted to us.

5. Usage analytics

We use Firebase Analytics (Google) to understand how the App is used — for example, which features are opened and how often, and to diagnose crashes. This includes:

Data	Purpose
App events (screen views, feature usage, e.g. "scan completed", "PDF shared")	Understand feature usage and improve the App
Device/app identifiers (Firebase installation ID, device model, OS version, app version)	Attribute events to a single install, without identifying you personally

We do not send document content, file names, extracted OCR text, or photo library contents to Firebase Analytics.

6. Subscription and purchase data

Subscriptions are managed by RevenueCat and billed through the Apple App Store / Google Play. RevenueCat receives:

Data	Purpose
An anonymous app user ID, purchase/subscription status, transaction history	Verify your entitlement to PDFix Pro features and manage renewals/cancellations

To attribute subscription revenue to app usage, the RevenueCat app user ID is linked with the Firebase Analytics app instance ID. This link does not include your name, email, or payment details — App Store/Google Play handle billing directly and we never see your card information.

Data We Do NOT Collect

We do not require sign-up or a user account.
We do not collect your name, email address, or phone number.
We do not access your contacts.
We do not sell your data to third parties.

Third-Party Services

Firebase Analytics (Google)	Usage analytics, crash diagnostics	policies.google.com/privacy
RevenueCat	Subscription management	revenuecat.com/privacy

Data Retention

Your documents remain on your device until you delete them. We never auto-delete user documents. Analytics data is retained by Firebase according to Google's standard retention settings. Deleting the App from your device removes all locally stored documents.

Your Choices

You can deny camera or photo library access at any time in your device Settings; core scanning features will not work without camera access.
You can request deletion of analytics data associated with your device by contacting us (see below) — we will forward the request to Firebase where applicable.
You can cancel your subscription anytime through your Apple ID / Google Play account settings.

Children's Privacy

The App is not directed at children under 13, and we do not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
