Link to privacy policy of third-party service providers used by the app:
Our app includes an "Audio Study Mode" designed to help drivers study hands-free. To function, this feature requires access to your device's microphone and speech recognition capabilities.
Microphone Access: We use the microphone solely to listen for your voice commands (e.g., answering "A", "B", "C", or "D") during practice tests.
Data Handling: Audio data captured by the microphone is processed locally on your device or via your device's native speech-to-text engine to convert speech into text. We do not record, save, or upload your voice data to any external server. The audio is processed in real-time and discarded immediately after the command is recognized.
To provide features such as "Exam Readiness" tracking and "Mistake Detection," the app stores certain data locally on your device, including:
Your name or nickname (entered during onboarding).
Your scheduled exam date.
Your quiz scores and progress history.
Questions you have bookmarked or answered incorrectly.
This data is stored securely on your device using SharedPreferences (Android) or UserDefaults (iOS) and is never transferred to Shift Mobile servers. If you uninstall the app, this data will be permanently deleted.
We use Google AdMob to display advertisements. AdMob may use your device's Advertising ID (IDFA on iOS, AAID on Android) to serve personalized ads based on your interests. You can control this in your device settings under "Privacy" -> "Tracking" (iOS) or "Ads" (Android).
We want to inform you that whenever you use our Service, in a case of an error in the app we collect data and information (through third-party products) on your phone called Log Data. This Log Data may include information such as your device Internet Protocol (“IP”) address, device name, operating system version, the configuration of the app when utilizing our Service, the time and date of your use of the Service, and other statistics.
We value your trust in providing us your Personal Information, thus we are striving to use commercially acceptable means of protecting it. But 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.

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.
