PDF Toolkit (“the app”) merges, splits, reorders, rotates, stamps, locks, unlocks and converts PDF files on your Android device. This policy explains what the app does and does not do with your files and data.
Every operation runs entirely on your device. The PDFs
and images you open are read from the location you chose, processed
locally, and the results are written to Downloads/PDF Toolkit
(PDFs) or Pictures/PDF Toolkit (images). No file, page,
image, or text from a document is ever uploaded, and the developer
has no access to any of it. The original file is never modified; every tool
writes a new copy.
While a file is open the app keeps a private working copy in its own cache so pages can be shown and processed quickly. That copy is deleted when you leave the tool, and in any case when the app’s cache is cleared.
When you unlock a password-protected PDF, the password you type is used in memory to open that file and is not stored, logged or transmitted. When you lock a PDF, the passwords you set are written into that output file only, in the form the PDF standard defines. The app never records them anywhere else.
All of this lives in the app’s private storage. Clearing the app’s data or uninstalling the app removes it permanently.
1. Advertising. The app shows ads via Google AdMob (with Meta Audience Network as a mediation partner). The ads SDK may collect device identifiers (such as the advertising ID), coarse location derived from IP, and diagnostic signals to serve and measure ads. In the European Economic Area, the United Kingdom and regulated US states, ads are only requested after you make a choice in the consent dialog (Google UMP), and you can change that choice at any time in Settings → Ad privacy options.

2. Analytics and crash reporting. The app uses Google Firebase Analytics and Crashlytics to understand which tools are used and to fix crashes. Analytics events record usage shapes only: which tool ran, how many files and pages were involved as a range (for example “2–5”), how long it took, and an error code if it failed. Never a file name, a path, a page’s content, a watermark text or a password. Crash reports contain stack traces and device model information.
The app requests the INTERNET permission for advertising,
analytics and crash reporting. On Android 9 and earlier it also requests
storage write permission so it can save results to your Downloads folder;
Android 10 and later need no storage permission for this. Files are opened
through the system file picker, the photo picker, or when another app
shares or opens a PDF with this one, so the app never needs broad access to
your storage.
The app is a general utility and is not directed at children under 13.
