Callopus

Privacy Policy

Last updated: October 11, 2026

1. Overview

At Callopus (operated by Inklyre), your privacy is fundamental to how we build software. We believe learning should be private, calm, and distraction-free.

2. What We Collect and Why

We collect only the minimum information necessary to provide and support our services:

  • Account Information: When you sign in, our authentication provider receives your name and verified email address to authenticate you and manage your subscription.
  • Payment Information: All payments are processed directly by our payment gateway partner (Razorpay). Callopus never sees, processes, or stores your credit or debit card numbers, UPI PINs, or banking passwords. We store only subscription records (your plan name, payment dates, transaction identifiers, and amounts) for account entitlement and billing records.
  • Callopus AI Requests: If you use built-in Callopus AI, your prompts, questions, and contextual document snippets are securely transmitted to the AI services that answer them solely to generate your response. We count token usage against your plan allowance. Prompts and responses are not retained after answering, beyond temporary logs retained for security and abuse detection for at most 30 days.
  • Support Inquiries: If you contact us via email, we keep your message and email address to troubleshoot issues and assist you.

3. What Stays on Your Computer

The vast majority of your study data remains local to your device and never reaches our servers:

  • Your courses, video progress, notes, notebooks, and study schedules;
  • Your PDF documents, textbooks, EPUBs, and reading annotations;
  • Your flashcards, study decks, and spaced repetition intervals;
  • Your Own API Keys: Every AI request made using your personal API keys (OpenAI, Anthropic, Google Gemini, OpenRouter, or local Ollama) connects directly from your computer to that provider without passing through Callopus servers.

4. No Advertising, No Selling of Data

We do not sell, rent, monetize, or trade your personal data. We do not use third-party advertising tracking scripts, cross-site trackers, or marketing cookies.

5. Service Providers

We work with trusted infrastructure providers by role to operate our service:

  • Authentication: Secure user sign-in and token issuance.
  • Payment Processing: Payment gateway handling subscriptions, UPI Autopay, and cards.
  • Hosting & Edge Infrastructure: Content delivery network and application servers.
  • AI Providers: The AI services that answer Callopus AI’s questions for Callopus AI plans.

6. Your Rights under India’s DPDP Act, 2023

In accordance with India’s Digital Personal Data Protection Act, 2023, you have the right to request access to the personal data we hold about you, request corrections or updates to inaccurate data, request erasure of your personal data when no longer needed, and nominate an individual in the event of incapacity.

7. Grievance Officer

If you have questions, concerns, or grievances regarding your personal data or wish to exercise your rights, you may contact our designated Grievance Officer:

Grievance Officer, Inklyre
Email: support@callopus.com

We acknowledge and respond to all data protection grievances within 30 days.

8. Children’s Privacy

Callopus does not knowingly collect personal data directly from children under 18 without parental or legal guardian consent. If you believe a minor has registered an account without consent, please contact us to remove the account.

9. Updates to this Policy

We may update this Privacy Policy from time to time. Any material changes will be announced on this page and communicated by email to active subscribers.
