Engineeringa2z (“we,” “our,” or “us”) publishes the Engineeringa2z mobile application (“the App”). The App provides access to educational articles, study notes, previous-year question papers and engineering tools available through our website, https://www.engineeringa2z.com/.
This Privacy Policy explains what information may be processed when you use the App, how that information is handled, and what choices are available to you.
1. Use of the App Without an Account
You do not need to create an account or register to use the App’s main features.
You can browse educational content, read articles, access available study materials and use supported engineering tools without creating an account.
2. Information Stored on Your Device
The App stores certain information locally on your device to provide a convenient user experience. This may include:
- Saved or bookmarked articles
- Reading history
- Offline downloads are saved in the app’s storage on your phone and removed if you uninstall the app.
- App preferences, such as theme and text size
This locally stored information is not sent to us by the App. You can remove applicable saved information through the App’s Settings or by clearing the App’s data through your device settings.
Please note that clearing app data may remove locally stored preferences, bookmarks, history and downloaded files.
3. Push Notifications
If you grant notification permission, the App uses OneSignal to deliver notifications about new articles and relevant updates.
To provide this service, OneSignal may process a push subscription identifier and basic device and app information, such as:
- Device model
- Operating system version
- App version
- Device language
- App language
Notification permission is optional. You can turn push notifications off in the App’s Settings (where available) or in your device’s notification settings. Study reminders can be turned off separately in the App’s Settings.
For more information about how OneSignal handles information, please read its Privacy Policy.
Study reminders, streak and language
Study reminders: The app can show a daily study reminder on your phone. Reminders are scheduled on your device using your phone’s own time zone, and work without internet. Your reading streak, preferred reminder time (including the “Smart time” that learns when you usually read), and quiet hours are stored only on your phone and are not sent to us. You can turn reminders, extra nudges and quiet hours off anytime in Settings. The app may restart reminders after your phone reboots.
Language: The app is available in 10 languages. Your chosen language is stored on your phone.
4. Comments, Forms and Voice Input
If you choose to submit a comment or complete a form within the App, the information you provide may be transmitted to our website, https://www.engineeringa2z.com/.
Depending on the form, this information may include your name, email address and message.
Some forms may use Google reCAPTCHA to help protect against spam and automated submissions. Its use is subject to Google’s applicable Privacy Policy and Terms of Service.
Comments may be reviewed by us before they are published publicly.
Please avoid submitting sensitive personal information in comments or public forms.
Microphone: If you tap the mic button in a tool (for example AI Notes Generator), the app uses your phone’s speech recognition to turn your voice into text. The microphone is used only while you use it, and recordings are not stored by us. Your phone’s speech service (for example Google) may process the audio under its own policy.
5. Articles, PDFs and Website Content
The App loads articles, educational resources and other pages from engineeringa2z.com. Some PDF documents may be hosted on Google Drive.
When your device requests content from these services, the relevant service may receive your IP address and other technical information associated with normal internet requests.
The handling of such information is also subject to the applicable privacy policies and practices of those services.
6. Information We Do Not Collect or Sell
The App does not sell your personal data.
The App does not display third-party advertising and does not collect your precise location, contacts, photos or files as part of its described functionality.
Some information may nevertheless be processed by third-party services when you use features such as push notifications, website forms, reCAPTCHA or externally hosted PDF documents, as explained in this policy.
7. Children’s Privacy
The App is intended for students and general readers. It is not directed at children under the age of 13.
8. Data Security
We aim to handle information responsibly and maintain appropriate safeguards for the App and its associated services.
However, no method of electronic transmission, internet access or data storage can be guaranteed to be completely secure. You should use the App and submit information online with appropriate care.
9. Third-Party Services and Websites
The App may rely on third-party services to provide particular features, including OneSignal for push notifications, Google reCAPTCHA for spam protection, and Google Drive for certain documents.
When you access third-party services or resources, their own terms and privacy policies may apply. We encourage you to review the relevant policies to understand how those services handle information.
Firebase Crashlytics
If the app crashes, Firebase Crashlytics (Google) may receive a crash report with technical details such as device model, OS version and app version. It does not include your name or email.
10. Search
When you search inside the app, the words you type are sent to engineeringa2z.com to find matching articles. The app also keeps your recent searches on your phone so you can reuse them. You can clear them anytime inside the app (Search > Clear all).
11. Data deletion requests
The app has no user accounts. Saved articles, reading history, offline articles, downloaded PDFs, recent searches and settings are stored only on your phone, and you can delete them from the app Settings or by clearing the app data in your phone settings. If you want us to delete a comment, or the name or email you sent through a comment, subscribe or contact form, or any other data we hold, email contact@engineeringa2z.com with the details and we will delete it within a reasonable time.
12. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes to the App, its features or our information-handling practices.
The latest version will be available on this page. Please review this page periodically for updates.
