Privacy Policy

Effective November 13, 2026

PDF Doctor ("the app") is a document reader, annotator, converter and Markdown editor for iPad and iPhone. This policy explains what data the app accesses and what it does with it. In short: your documents and account data stay between your device and the storage services you choose. We do not operate servers that receive your data, and we do not collect analytics.

Data the app handles

Your documents. Files you open, annotate, convert or write are processed on your device. They are stored only where you keep them: on your device, in iCloud Drive, in Google Drive, or in a folder you link from the Files app.
Google account data (only if you connect Google Drive). Your Google account email and name are shown in the app so you know which account is connected. Sign-in tokens are stored in your device's Keychain.
App preferences. Settings such as paper size, recent documents, bookmarks and saved signatures are stored locally on your device.

The app does not include advertising, tracking or analytics SDKs, and it does not sell, rent or share your data with anyone.

Google user data

When you connect Google Drive, the app asks for these permissions:

https://www.googleapis.com/auth/drive — to list your files and folders (My Drive, Shared with me, shared drives), download the files you open, upload converted PDFs and annotated files, create folders, rename files and move files to the trash, all only when you ask for it in the app.
openid, email, profile — to show which Google account is connected.

How Google data is used:

File contents are downloaded directly from Google to your device so you can view, annotate or convert them, and kept in the app's on-device cache. Changes you make are uploaded directly back to your Google Drive.
Google data is never transferred to the developer or to any third party, never used for advertising, and never used to train AI or machine-learning models.
No human reads your Google data.

PDF Doctor's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

On-device processing

Text recognition (OCR), document conversion and Markdown rendering run entirely on your device using Apple frameworks. No document content is sent to external services for processing.

Retention and deletion

To disconnect Google Drive, open Settings → Google Drive → Sign Out in the app. This revokes the app's access token and removes it from your device. You can also remove access at myaccount.google.com/permissions.
Deleting the app removes its cached files and local settings from your device.
Files you saved to iCloud Drive, Google Drive or other locations remain there under your control.

Children

The app is not directed at children under 13 and does not knowingly collect their personal information.

Changes

If this policy changes, the updated version will be posted on this page with a new effective date.
