This Privacy Policy (“Policy”) explains how the Prep DNB mobile application (the “App”) collects, uses, stores, and protects information. Prep DNB is a medical education app designed to support DNB/DipNB exam preparation with previous year question papers, important topics, and MCQ practice.
The App is developed and maintained by Docodex Labs (“Developer,” “we,” “us,” “our”). By using the App, you agree to this Policy. If you do not agree, please discontinue use.
2.1 Information You Provide
Prep DNB does not require account creation. In normal use, you do not provide personal information directly to us.
If you contact us by email (e.g., for support/feedback), we will receive:
Your email address and the contents of your message (only what you choose to send)
2.2 Information Stored Locally on Your Device
The App stores limited preferences locally on your device, such as:
Theme preference (light/dark mode)
App state needed for a smoother experience (e.g., selections/navigation state)
This data is stored locally using platform storage (e.g., SharedPreferences) and is not transmitted to our servers by the App.
2.3 Information We Do Not Collect (by default)
The App does not collect or require:
Name, phone number, address (unless you email us and include them)
Payment card details inside the App (billing is handled by Apple/Google)
Precise location data
Contacts, calendars, photos, files
Microphone/camera recordings
Health/medical history data (the App is for study content; it does not request clinical data)
2.4 Analytics / Crash Reporting
As of this version, Prep DNB does not include third‑party analytics SDKs or crash reporting SDKs that automatically transmit identifiable user data to us.
Note: Your device OS (iOS/Android) or the app store platform may still collect some diagnostic or usage information under their own policies. This is controlled by Apple/Google and your device settings.
We use information only to:
Provide core functionality (remember settings like theme)
Respond to support requests if you contact us by email
Improve the app based on general feedback and bug reports you choose to share
We do not use personal data for targeted advertising.
4.1 On-Device Storage
Preferences are stored locally on your device. They remain until you:
Uninstall the App, or
Clear the App’s data/storage (platform dependent)
4.2 Email Support Retention
If you email us, we may retain the email thread as long as needed to:
Respond, troubleshoot, and maintain support history You may request deletion of support emails by contacting us.
5.1 Third-Party Packages (in-app functionality)
The App uses common Flutter packages such as:
shared_preferences – stores user preferences locally
google_fonts – loads fonts (may download font files at runtime)
url_launcher – opens links in external apps/browsers
share_plus – shares text via other apps when you tap Share
5.2 Sharing via “Share”
When you use sharing features, the content is shared only when you initiate it and is handled by the destination app/service you choose (e.g., Messages, Mail, WhatsApp, etc.). Their privacy policies apply.
5.3 External Links
The App may open external links (e.g., NBEMS pages). We are not responsible for the privacy practices of external websites.
The App may access the internet for:
Opening links you tap
Downloading fonts used by the app (e.g., via Google Fonts)
Your device/network provider and those services may log standard request metadata per their policies.
Prep DNB is intended for medical students and professionals (typically 18+). We do not knowingly collect personal data from children under 13. If you believe a child has provided personal information to us via email/support, contact us and we will take appropriate steps.
We take reasonable measures to protect information:
Minimal data collection by design
Preferences stored locally and protected by your device security However, no method of transmission or storage is 100% secure.
You can:
Delete local data by uninstalling the App (or clearing app storage)
Stop sharing by not using Share features
Contact us to request deletion of support emails you sent to us
We may update this Policy to reflect app changes, legal requirements, or operational updates. The “Last Updated” date will change accordingly. Continued use of the App after updates means you accept the revised Policy.
