Privacy Policy

Overview

Teengro ("we", "our", "us") is an AI-powered tutoring platform for students in grades 8–12, available at teengro.in. We are committed to protecting your privacy and being transparent about how your data is handled.

This Privacy Policy applies to all users of Teengro, including users of our website and mobile app.

Information We Collect

Learning Data

• Class, board, and subject preferences you set
• Preferred reply language (English, Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Marathi, or Gujarati)

• Files you upload to the AI for help — images, PDFs, and plain text files (sent to the AI for the response and not permanently stored by Teengro)

• AI-generated diagrams you request (stored in our secure file storage so they appear in your chat history)
• Flashcards you create or generate (stored against your account so you can study them again)
• Ratings (thumbs up / thumbs down) on individual AI replies, used to improve answer quality
• Study time and usage activity
• Day streak, freeze count, and session history
• Earned badges and achievements
• Daily AI usage (token count) to manage fair usage limits

Technical Data

• Time spent on the app
• Service-worker cache (used so Teengro works offline; stored only in your browser)
• Local browser storage for theme preference, preferred reply language, and pending sync data

How We Use Your Data

• To create and manage your account
• To personalise your learning experience (class, board, subject, and reply language)
• To power the AI tutor responses, image generation, and flashcard generation
• To match each reply to your preferred language and the right NCERT chapter
• To track your study streaks, badges, and progress
• To improve Teengro's features, answer quality, and performance
• To enforce fair daily usage limits
• To send important account-related emails (e.g. password reset)

We do not sell your data to third parties. We do not use your data for advertising. We do not train AI models on your conversations.

Third-Party Services

Teengro uses the following trusted third-party services to operate:

• Supabase — secure database, authentication, and file storage
• Google Gemini — AI model powering tutor responses, multilingual replies, and diagram generation
• Vercel — hosting and content delivery for the website
• Browser Speech API — for voice-to-text input (runs locally in your browser; audio is not sent to Teengro)
• Cloudflare Turnstile — bot protection on login and signup (no personal data collected)
• Google Analytics — anonymous usage analytics to improve the app
• Google Fonts — typography rendering

Each of these services has their own privacy policies and data handling practices.

Data Storage & Security

Your data is stored securely using Supabase, which uses industry-standard encryption and row-level security so that only you can access your own data. Passwords are hashed and never stored in plain text. We take reasonable steps to protect your information from unauthorised access.

Chat history is stored in our database so you can revisit past conversations. You can delete individual sessions or all history at any time from the app.

AI-generated diagrams are stored in Supabase Storage (a secure file storage service) linked to your account. They are only accessible to you.

Files you upload (images, PDFs, text) for analysis are forwarded to Google Gemini for that single response and are not permanently stored by Teengro.

Flashcards are stored against your account in Supabase so you can study them across sessions and devices.

Voice input is processed entirely in your browser using the Web Speech API. The recorded audio never leaves your device — only the transcribed text reaches Teengro.

Children's Privacy

Teengro is designed for students in grades 8–12 (typically ages 13–18). We do not knowingly collect personal information from children under the age of 13 without parental consent. If you believe your child has provided us with personal data, please contact us and we will delete it promptly.

Data Retention

We retain your data for as long as your account is active. Specifically:

• Chat history — kept until you delete it or close your account
• Generated diagrams — stored in your account's file storage, deleted when you delete the session or close your account
• Flashcards — kept until you delete them or close your account
• Usage data (streaks, study time, token count, badges) — kept with your account profile
• Ratings on AI replies — kept in aggregate to help us improve answer quality
• Account data — deleted within 30 days of account deletion upon request

Your Rights

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your account and data
• Withdraw consent at any time by deleting your account

To exercise any of these rights, contact us at the email below.

Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of Teengro after changes means you accept the updated policy.
