Privacy Policy
How EDUBUS UNICON PRIVATE LIMITED ("Mentorbox", "we", "us", or "our") collects, uses, and protects your information when you use the Mentorbox AI mobile application. By using the App, you agree to this Policy.
We collect only what we need to run the App. The App is operated by EDUBUS UNICON PRIVATE LIMITED, First Floor, Office No-02, Plot No-055, Knowledge Park-5, Greater Noida, Gautam Buddha Nagar, Uttar Pradesh – 201306, India (GSTIN: 09AAGCE6867Q1ZM).
Information You Provide
Mobile number
Required to create your account and sign in via a one-time password (OTP). We do not use passwords.
Profile details
Your name, class/batch, target exam year, and study goal, which you enter to personalise the App.
Content you submit
Test answers, study-planner entries, bookmarks, flagged questions, and any messages, questions, or files/images you send to our AI chat feature.
Voice data
Audio you speak to our AI voice assistant, captured only while you are actively in a voice call that you started, and only after you consent to AI processing (see Section 04).
Information Collected Automatically
Authentication token — a secure session token (JWT) stored encrypted on your device to keep you logged in.
Usage and performance data — your test attempts, scores, accuracy, and study progress, which power your analytics.
Diagnostics and crash data — technical diagnostic information collected via our error-monitoring provider (Sentry) if the App crashes or errors.
Technical data — standard information such as your IP address and device/app version, received by our servers.
Push notification token — a device token issued by Firebase Cloud Messaging, used to deliver notifications to your device if you enable them.
We do not collect your precise location, contacts, photo library, or financial information. We request microphone access only when you actively start a call with our AI voice assistant — see Section 04 for how that audio is shared with our voice processing provider.
How We Use Your Information
- To create and secure your account and sign you in (OTP verification)
- To provide the App's features — practice tests, mock tests, study planner, progress analytics, bookmarks, and AI-assisted doubt solving
- To personalise your experience (e.g., your name, target year, and recommendations)
- To maintain, debug, and improve the App's stability and performance
- To comply with legal obligations and protect against misuse or fraud
How We Share Your Information
We do not sell your personal information. We share data only with service providers who help us operate the App:
Google Gemini
When you use our AI chat feature, your messages and any files/images you attach are sent to Google's Gemini AI models (Google LLC) to generate a response.
Sarvam AI
When you use our AI voice assistant, your spoken audio is sent to Sarvam AI for speech-to-text transcription and text-to-speech generation of the assistant's reply.
Message Central
When you sign in, your mobile number is sent to Message Central to deliver the one-time password (OTP) used to verify your account.
Firebase Cloud Messaging
If you enable notifications, your device's push token is registered with Firebase Cloud Messaging (Google LLC) to deliver notifications to your device.
Infrastructure
Our hosting/back-end infrastructure, which powers doubt solving and routes chat/voice requests to the providers above.
Sentry
Crash and error diagnostics (Functional Software, Inc.).
Legal / authorities
Where required by law, regulation, or valid legal process.
These providers process data only on our behalf, under contractual obligations that require them to protect your data to the same or equal standard described in this Privacy Policy. Before any message, file, or voice recording is sent to Google Gemini or Sarvam AI, the App shows an in-app consent screen naming the provider and the data it will receive; nothing is sent unless you tap "Allow", and choosing "Cancel" simply keeps the AI chat/voice feature from sending your content. We do not share your personal data — such as your name, mobile number, or email address — with these AI providers; they receive only the content of your message or voice audio.
What Each Piece of Data Is Used For
The table below sets out, for every kind of data the App handles, how we collect it, who receives it, and exactly what it is used for. Anything not listed here is not collected — we do not collect your precise location, contacts, health data, or an advertising identifier, and the App contains no third-party advertising or analytics trackers.
| Data & how we collect it | Who uses it | What it is used for |
|---|---|---|
Mobile number You type it on the sign-in screen. | Mentorbox + Message Central | Creating your account and sending the one-time password you sign in with. It is never sent to our AI providers. |
Your name You type it during onboarding. | Mentorbox app only | Personalising the App — greeting you by name and labelling your progress. It stays on our servers and is not shared with Google Gemini or Sarvam AI. |
Class, target exam year and study goal You choose them from the options shown during onboarding. | Mentorbox app only | Pacing your study plan, choosing which syllabus and tests to show you, and writing your recommendations. |
Photos and files you attach to AI chat Captured with your camera, or picked by you from your photo library or files — only the individual items you select after tapping the attach button. | Google Gemini | Reading the question in your photo or document so the AI can solve it. We only ever receive the specific image or file you pick — the App never scans or reads your photo library. |
Messages you type in AI chat You type them into the chat composer and tap send. | Google Gemini | Generating the answer you asked for. Only the content of your message is sent — not your name, mobile number, or email. |
Voice audio in the AI voice assistant Streamed from your microphone while a voice call you started is open, and stopped when you end the call. | Sarvam AI, then Google Gemini | Turning what you said into text and speaking the reply back to you. Captured only while you are in a call you started, and only after you allow it. |
Dictation (the mic button in chat) Recorded by your device's own speech recogniser while you use the mic button in the chat composer. | Your own device | Typing your message for you. This is handled by your phone's built-in speech recogniser — the audio is never sent to Mentorbox. |
Test answers, scores and study activity Recorded by the App as you attempt tests and use the bookmarks, flags and study planner. | Mentorbox app only | Marking your attempts and building your accuracy, progress and analytics. Includes bookmarks, flagged questions and study-planner entries. |
Device identifier Generated by the App on this device the first time you sign in, and kept in encrypted on-device storage. | Mentorbox app only | Keeping you signed in on this device and protecting your account. It is a random ID we generate for this installation — not a hardware ID, and not an advertising ID. |
Push notification token Issued to the App by Firebase Cloud Messaging when you allow notifications. | Firebase Cloud Messaging (Google) | Delivering the notifications and daily reminders you have turned on. Turning notifications off stops it being used. |
Crash and error diagnostics Collected automatically by the App when it crashes or hits an error. | Sentry | Telling us what broke so we can fix it. Reports carry technical details such as the error and app version — not your name, number, or study content. |
Purchase information Returned to the App by the App Store or the payment page once you complete a purchase. | Apple (iOS) or Razorpay (Android) | Confirming your Premium purchase and unlocking it on your account. Your card and payment details are handled entirely by the store or payment provider and are never seen or stored by the App. |
The App asks for the microphone only when you start a voice call or tap the dictation button, and for the camera or your photos only when you choose to attach an image to an AI chat. You can decline any of these and continue using the rest of the App.
Purchases and Premium Access
iOS (iPhone)
On Android and on our website, Premium is sold through our payment provider, Razorpay. A Razorpay purchase unlocks Premium on Android and on the website; it does not unlock Premium in the iOS app, which recognises Apple In-App Purchases only.
We never see or store your card, UPI, or bank details. Apple and Razorpay handle the payment in full and return to us only a confirmation that it succeeded, which we use to unlock Premium on your account (see the "Purchase information" row in Section 05). Refunds for App Store purchases are handled by Apple under its own terms; for everything else see our Refund Policy.
Data Storage and Security
We use industry-standard measures to protect your data, including encryption in transit (HTTPS) and encrypted on-device storage of your session token. No method of transmission or storage is 100% secure, but we work to protect your information.
Data Retention
We retain your information for as long as your account is active or as needed to provide the App. You may request deletion of your account and associated data at any time; we will delete it except where we must retain certain records to comply with legal obligations.
Your Rights and Choices
Depending on your location, you may have the right to access, correct, or delete your personal data, or to withdraw consent. To delete your account and data, email tech@mentorbox.ai as described on our Account & Data Deletion page. For any other privacy request, email support@mentorbox.ai.
Children's Privacy
Changes to this Policy
We may update this Policy from time to time. We will post the updated version here with a new "Last updated" date. Continued use of the App after changes means you accept the updated Policy.
