Effective Date: May 5, 2026
Techtenstein Services Pvt Ltd ("we," "us," or "our") built the PDF Document Viewer & Reader app (the "App") as a Commercial/Ad-Supported app. This SERVICE is provided by Techtenstein Services Pvt Ltd and is intended for use "as is."
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.
If you choose to use our Service, then you agree to the collection and use of information in relation to this policy. The Personal Information that we collect is used for providing and improving the Service. We will not use or share your information with anyone except as described in this Privacy Policy.
For a better experience while using our Service, we may require you to provide us with certain personally identifiable information. The information that we request will be retained by us and used as described in this privacy policy.
Data We Collect Includes:
Personal Information: Name, Email address, User IDs, and Phone number (if provided during feedback, account creation, or support requests).
Media and Files: Photos and Documents. Because the App is a document reader and scanner, it requires access to your device's storage and camera to read, edit, convert, and save documents (PDF, DOCX, XLSX, etc.) and photos. Your documents and files are processed locally on your device and are not uploaded to our servers.
Device and Other IDs: We automatically collect certain device identifiers (such as IP address, device type, operating system version) for analytics, debugging, and advertising purposes.
To provide core functionalities, the App requests the following Android permissions:
Camera: Required to use the Document Scanner feature to digitize physical papers into PDFs.
Read/Write/Manage External Storage: Required to browse, open, edit, and save documents and generated PDFs directly on your device.
Internet & Network State: Required to serve advertisements, fetch updates, and report crash diagnostics.
Post Notifications: Used to alert you when background tasks (like compressing or merging large PDFs) are complete.
The App uses third-party services that may collect information used to identify you, serve advertisements, and analyze app performance.
We use the following third-party service providers:
Google Play Services: For core Android functionality and security.
Google AdMob: To serve contextual and personalized advertisements.
Unity Ads: Serving as an ad mediation partner to provide relevant advertisements.
These third-party ad networks may use cookies, device identifiers (such as Android Advertising ID), and usage data to show you targeted ads based on your interests. You can opt out of personalized advertising through your device's "Google Settings."
We value your trust in providing us your Personal Information, thus we are striving to use commercially acceptable means of protecting it. Please remember that no method of transmission over the internet, or method of electronic storage is 100% secure and reliable, and we cannot guarantee its absolute security.
Local Processing: All document editing, merging, splitting, and password-protection features are executed locally on your smartphone. We do not have access to the contents of your private documents.
This Service may contain links to other sites (such as through advertisements). If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by us. Therefore, we strongly advise you to review the Privacy Policy of these websites. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.
These Services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13 years of age. In the case we discover that a child under 13 has provided us with personal information, we immediately delete this from our servers. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us so that we will be able to do necessary actions.
We may update our Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page.
