This Privacy Policy explains how the StudyMark mobile application (“StudyMark”, “the app”, “we”) handles your information. StudyMark is a PDF reading and annotation app, primarily for students. Your privacy is important to us, and the app is designed to keep your data on your own device.

1. Information stored on your device

StudyMark stores all of your content locally on your device only. This includes:

• PDF books you import or download into the app,

• Your annotations (highlights, underlines, strikethroughs, pen drawings, and notes),

• Your bookmarks, folders, and study cards, and

• Your in-app settings and reading position.

This information stays on your device. We do not upload it, collect it, or transmit it to us or to any third party. We do not have access to it, and we cannot see it.

2. No accounts and no personal data collection

StudyMark does not require you to create an account or sign in. We do not collect your name, email address, location, contacts, or any other personal information. We do not use analytics or advertising tracking, and the app does not send your usage data to us.

3. Features that connect to the internet

Some optional features connect to the internet to work. When you use them, your request goes directly to the relevant service — it is not routed through us, and we do not receive or store the content:

• Translation. The app uses Google’s ML Kit on-device translation. The first time you use a language, a translation model is downloaded to your device; after that, translation is performed on your device.

• Browse books. When you browse or download free books, the app fetches catalog information and files directly from public sources such as Project Gutenberg and OpenStax.

• Web links. Features such as “Search on Google” and links to sources such as NCERT open the requested page in your device’s web browser.

These services are operated by third parties and have their own privacy policies. We encourage you to review the privacy policies of Google and of any book source you choose to use.

4. Permissions the app uses

StudyMark may request access to your device storage so that you can import PDF files and save downloaded books. This access is used only to read the files you choose and to store your books and annotations on your device. The app requests internet access only for the optional online features described above.

5. Children’s privacy

StudyMark does not knowingly collect any personal information from anyone, including children. Because all data stays on the device and no personal information is collected, the app does not gather data from users of any age.

6. Data security

Because your data is stored only on your own device, its security depends on your device’s own protections (such as your screen lock and device encryption). We recommend keeping your device secured.

7. Changes to this policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last updated” date.
