Privacy Policy

Last Updated: May 2, 2026

At RevPDF, your privacy is our top priority. Our app is designed to be offline-first, ensuring that your documents and data stay on your device. However, certain technical requirements differ between our Desktop and Mobile versions as outlined below.

1. No Personal Data Collection

RevPDF does not require you to create an account, sign up, or provide any personal information (such as your name, email address, or phone number) to use the app. We do not track your identity or build a profile of your usage across any platform.

2. Document Privacy

All PDF processing, editing, merging, compression, OCR, and scanning happen locally on your device using our native engine. No documents, images, or recognized text are ever uploaded to our servers or any third-party cloud services. Your files remain 100% under your control on macOS, Windows, Linux, Android, and iOS.

3. Offline Functionality & Internet Usage

RevPDF is built to work offline. All PDF editing, merging, compression, conversion, OCR, and document scanning happen locally on your device. However, the app may use an internet connection in the following specific, limited circumstances:

• Desktop (macOS, Linux, Windows): The desktop version is 100% free and ad-free. The desktop app may use the internet in two specific circumstances: (a) font loading — when a document requires a font not installed on your device (see Section 7); and (b) on Windows and Linux only, a one-time download of the Tesseract OCR language model on first use of the OCR feature (see Section 6). Both actions require your explicit consent before any connection is made.
• Mobile (Android & iOS): In addition to font loading (same process as desktop), the mobile app may connect to the internet to: (a) display banner advertisements for non-premium users via Google AdMob; and (b) process in-app purchase transactions through Google Play or the Apple App Store. Document scanning and OCR are fully on-device and require no internet connection.

In all cases, your PDF documents, scanned images, and any recognized text are never transmitted over the internet. Only font file assets and, on first OCR use for Windows/Linux, a language model file are downloaded — both only with your prior knowledge and consent.

4. Document Scanner (Mobile Only)

RevPDF includes a built-in document scanner on Android and iOS that lets you capture physical documents using your device camera and convert them into PDFs. This feature works entirely on-device:

• All edge detection, perspective correction, and image processing are performed locally using native platform APIs.
• No images or scan data are transmitted to any server or third-party service at any point during or after scanning.
• Scanned documents are processed and saved directly to your device storage under your control.

5. OCR — Text Recognition

RevPDF includes an OCR (Optical Character Recognition) feature that can extract and recognize text from scanned PDFs and images. All recognition is performed entirely on-device after any required one-time setup:

• iOS & macOS: OCR is powered by Apple's on-device Vision framework. No setup download is required and no data ever leaves your device.
• Android: OCR is powered by Google ML Kit, which runs entirely on-device. No text or image data is sent to Google servers during recognition.
• Windows & Linux: OCR is powered by Tesseract, a fully open-source, on-device OCR engine. Tesseract requires a language model file (eng.traineddata, ~4 MB) that is not bundled with the app. On first use of OCR, this file is downloaded once from the official Tesseract open-source repository on GitHub (github.com/tesseract-ocr/tessdata_fast). You will be shown an explicit consent dialog before any download begins and may decline — in which case OCR will remain unavailable until you choose to download it. The model is stored privately on your device and reused for all subsequent OCR operations with no further network requests. No document content or recognized text is ever transmitted during this download or during OCR processing.

On all platforms, once any required model is in place, OCR runs fully offline. Neither the source document nor any recognized text is ever transmitted outside your device.

6. Third-Party Services (Mobile Only)

On mobile devices, we use the following services which may collect data according to their own policies:

• Google AdMob (Android/iOS): We show banner ads to non-premium mobile users. AdMob may use advertising identifiers (like Android Advertising ID or IDFA) to serve ads.
• In-App Billing (Google Play / Apple App Store): Premium upgrades are handled securely by the respective app stores. We do not see or store your payment details.

7. Dynamic Font Loading

When you open a document that uses a font not already installed on your device, RevPDF attempts to resolve it in the following order, using the least-invasive source first:

• Step 1 — On-device fonts: The app first searches fonts already installed on your operating system or device. No internet connection is used.
• Step 2 — Google Fonts GitHub repository: If the font is not found on-device, the app attempts to download it directly from Google's open-source font repository hosted on GitHub (github.com/google/fonts). This avoids the Google Fonts API and its associated tracking.
• Step 3 — Google Fonts API (last resort): Only if the font cannot be retrieved through either of the above sources does the app fall back to the Google Fonts API.

Before making any external network request (Steps 2 or 3), you will be shown an in-app dialog clearly identifying the font being requested and the external service being contacted. You may decline the connection at any time, in which case the app will use a fallback system font.

No document content or personal data is transmitted during font loading. Only a font file identifier is sent to the external service — the same request any browser makes when loading a web font.

8. Premium Status

For mobile users, your "Premium" status is linked to your Google Play or Apple ID account. No other personal data is shared with us during this process. Desktop users enjoy all features for free with no account or billing required.

9. Changes to This Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
