Last updated: April 27, 2026
Kabushiki Kaisha Daisen ("we," "our," or "us") built the PDFox app as a freemium app supported by advertising and optional subscriptions. The free tier is provided at no cost. This privacy policy explains how we handle information when you use the app.
This page is used to inform visitors regarding our policies with the collection, use, and disclosure of Personal Information if anyone decides to use our Service.
INFORMATION COLLECTION AND USE
PDFox does not require user registration or login. We do not collect personal information such as your name, email address, or phone number.
The app uses the following third-party services that may collect information used to identify you:
Google AdMob (Advertising)
- On Android: collects the Advertising ID (AAID) to serve personalized ads.
- On iOS: may access the Identifier for Advertisers (IDFA) if the user grants App Tracking Transparency (ATT) permission. Users may decline this at any time via iOS Settings > Privacy & Security > Tracking.
- Users can opt out of personalized advertising on Android via device settings, and on iOS via the ATT permission prompt.
- Pro subscribers do not see advertisements and no advertising identifiers are accessed.
Google User Messaging Platform (Consent Management)
- Used to gather user consent for personalized advertising in regions where consent is legally required (e.g., GDPR in the EU).
Google Play Services (Android only)
- Used for core app functionality and ad delivery.
Apple StoreKit & App Store (iOS only)
- Used for in-app purchases and subscription verification.
RevenueCat (Subscription Management)
- We use RevenueCat to validate purchases and manage Pro subscription entitlements. RevenueCat receives anonymous device identifiers and subscription transaction data from Apple App Store and Google Play. No personally identifiable information is sent.

Sentry (Crash Reporting)
