Privacy Policy

We built claratto to help you learn — not to harvest your data. Here's exactly what we collect, why, and how we protect it.

Last updated: June 2026·Governed by the laws of India (IT Act, 2000)
01

Information We Collect

Account Information

We use Google OAuth via Firebase Authentication for sign-in. When you connect, we receive and store your name, email address, and profile photo URL. We never see your Google password.

Learning Activity (Your Brain)

To build and display your personal brain graph, we record:

  • Topics you learn and the canonical AI-generated name for each.
  • MCQ test scores and the resulting node strength (solid ≥75%, faint 45–74%, not stored <45%).
  • Brain node connections — the relationships between topics, AI-reasoned at test time.
  • Saved lesson notes — the AI's explanation stored after each initial teach session.
  • Syllabus documents — if uploaded, the parsed course structure (subjects + topics) stored in your account.

Conversation Context (App Memory)

To give the AI continuity within and across sessions, we store a rolling conversation summary per topic — recent messages verbatim, older messages compressed into a summary. This is capped and never grows unboundedly. It is separate from your brain graph.

Voice Interview Data

During voice interviews, your spoken answers are temporarily recorded and sent to Sarvam AI (Speech-to-Text). We do not retain the raw audio. We store only the resulting text transcript and structured feedback report inside your account on Firestore.

Payment Information

Payments are processed by Razorpay. We never see or store your card number, CVV, UPI PIN, or banking credentials — Razorpay handles all sensitive payment data under PCI-DSS compliance. We receive only the payment status, transaction ID, and order amount from Razorpay's webhook to credit your account.

Usage and Technical Data

We log API call metadata (model used, token counts, credit debits) server-side for billing accuracy and abuse detection. We do not use third-party analytics trackers or advertising pixels.

02

How We Use Your Information

  • Personalise AI tutoring — the model reads your existing brain nodes so it never re-teaches what you've already proven.
  • Score tests server-side and write passing results to your brain graph — never trusting the client.
  • Generate and deliver voice interview feedback reports.
  • Manage your plan tier, recurring credit grants, top-up pack balances, and interview limits.
  • Detect and prevent abuse of the test-gate system, credit system, and API quota.
  • Send billing receipts and important service notices to your account email.

We do not sell your data, use it for advertising, or share it with third parties beyond the service providers listed in Section 04.

03

Data Storage and Retention

Your profile, brain nodes, lesson notes, interview transcripts, and chat context are stored in Google Cloud Firestore, hosted in Google's secure cloud infrastructure with encryption at rest and in transit.

Data is retained for as long as your account is active. You can request full deletion at any time (see Section 05). If your account is inactive for 24 consecutive months, we may delete it and all associated data after providing 30 days' notice by email.

04

Third-Party Services

We share only what is strictly necessary with the following trusted providers:

ServiceWhat we share & why
Firebase (Google)Account authentication (OAuth) and Firestore database hosting. Governed by Google Cloud's data processing terms.
Google GeminiAI text generation, tutoring, MCQ generation, and syllabus parsing. Lesson prompts include your topic and brain context — never your name or email.
Anthropic ClaudeUsed for interactive visualisation generation on paid plans. Receives only the topic context, not personal identifiers.
Sarvam AISpeech-to-Text and Text-to-Speech for voice interviews. Receives audio recordings; we store only the resulting text.
RazorpayPayment processing. Receives billing information under PCI-DSS. We receive only transaction metadata via signed webhook.
Upstash (Redis)Rate-limiting and quota counters per user. Receives anonymised user ID and call counts — no content.
VercelApplication hosting and edge delivery. Processes request data per Vercel's privacy policy.
05

Your Rights and Choices

You have the right to:

  • Access — request a copy of all personal data we hold on your account.
  • Correction — request correction of inaccurate data.
  • Deletion — request complete erasure of your profile, brain nodes, lesson notes, and interview history.
  • Portability — request your brain node data in a machine-readable format.
  • Withdrawal — stop using the service at any time; your data remains available for deletion on request.

To exercise any of these rights, email us at support@devstudiolabs.in with the subject line "Data Request — [your email]". We will process your request within 14 business days.

06

Cookies and Tracking

claratto uses only functional cookies — specifically the Firebase Authentication session token stored in your browser's local storage to keep you signed in across sessions. We do not use advertising cookies, cross-site trackers, or third-party analytics scripts.

07

Security

We take the following measures to protect your data:

  • All AI calls and Firestore writes happen server-side behind Firebase ID token verification — the browser never writes directly to the database.
  • Test scores and brain state are computed and written server-side, making them unforgeable from the client.
  • AI API keys are server-only environment variables — never exposed to the browser.
  • Razorpay webhook signatures are verified with HMAC-SHA256 before any credit grant.
  • Firestore security rules deny all client writes; reads are owner-only.
08

Governing Law

This Privacy Policy is governed by the laws of India, including the Information Technology Act, 2000, and applicable rules thereunder. Disputes are subject to the exclusive jurisdiction of courts in Mumbai, Maharashtra, India.
