What this policy covers
This privacy policy explains how the mobile application Unlock PDF (the “app”) handles information when you use it. The app is published under the package name com.unlockpdf.removepassword.
How the app works
Unlock PDF removes a password from a PDF that you already have the password for, and strips owner-permission restrictions (such as limits on printing, copying, or editing). It does not recover or crack forgotten passwords. All of this processing happens 100% on your device. Your PDF files are never uploaded to any server and never leave your device.
The short version
- Your PDF files never leave your device. All unlocking happens locally on your phone.
- The app only removes a password you already know, and strips owner restrictions. It does not recover or crack forgotten passwords.
- We do not collect, store, or transmit the content of your documents.
- The app does not require an account or sign-up.
- The app shows ads through Google AdMob, which uses your device’s advertising identifier.
What we do NOT collect
- Your PDF files, their content, or any text or images inside them.
- The passwords you enter to open your files. They are used only on your device, in memory, and are never stored by the app or sent anywhere.
- Your name, email address, phone number, or other personal identifiers (unless you choose to send them to us through the contact form).
- Your precise location.
- Your contacts, calendar, microphone, camera input, or files other than the PDFs you choose to unlock.
What stays on your device
Unlocked PDFs are written to a private app folder so the app’s History screen can list your recent results and let you re-share them. Your recent jobs (file name, original and output file size, timestamp, and whether a password or restrictions were removed) are stored locally in an on-device database, capped at 50 entries with the oldest removed automatically. The content of your PDFs and the passwords you enter are never uploaded by us.
Permissions the app requests
File access
The app lets you pick PDF files to unlock. It reads only the files you explicitly select through the system file picker and never scans your device storage for any other purpose.
Internet access
The app uses the internet only to serve advertisements (Google AdMob) and to load Google’s consent form. Your PDF files, their contents, and the passwords you enter are never sent over the network.
Advertising via Google AdMob
We monetize the app with Google AdMob. AdMob may collect and process the following on Google’s servers in order to serve and measure ads:
- Your device’s advertising identifier (Google Advertising ID on Android).
- General device information such as device model, OS version, language, and approximate region.
- IP address and ad interaction events.
In the European Economic Area, the UK, and Switzerland, the app presents a Google-certified consent message (Google’s User Messaging Platform) on first launch so you can choose whether ads are personalized. You can reset or remove your advertising identifier at any time in your device settings. Google’s use of advertising data is governed by Google’s own privacy policy: policies.google.com/privacy, and AdMob’s practices are described here: support.google.com/admob/answer/6128543.
Data sharing
We do not sell your data. The only party that receives any data is Google, through the AdMob service above, acting to provide advertising functionality on our behalf, subject to Google’s terms and privacy policy.
Children
The app is a general-audience utility and is not directed at children under the age of 13. We do not knowingly collect any personal information from children. If you believe a child has provided information, contact us and we will respond.
Data retention
Locally-stored job history stays on your device only and is capped at 50 entries. You can clear all history at any time from inside the app (History, then the clear icon). Uninstalling the app deletes all on-device data. Data held by Google AdMob is retained according to Google’s policies.
Your rights
Because we do not collect personal data on our own servers, there is nothing on our side for you to access, correct, export, or delete. For data Google may hold about your device’s advertising identifier, you can manage your preferences in your device settings or via Google’s ad settings page: adssettings.google.com.
Changes to this policy
We may update this policy as the app evolves. The current version is indicated by the “Last updated” date below. Material changes will be published at this URL before they take effect in the app.
