Terms and Conditions of Service

By accessing, browsing, registering for, or using TopicDrop (accessible at https://topicdrop.ighosh.com, referred to as the "Service", "Platform", or "TopicDrop"), operated by Indranil Ghosh under the brand / trade name Ighosh Studio ("we", "us", or "our"), you ("User", "Learner", "Parent", or "Teacher") acknowledge that you have read, understood, and agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you must discontinue use of the Service immediately.

To use TopicDrop, you must have the legal capacity to enter into a binding agreement or use the Platform with the parental or lawful-guardian consent or supervision required by applicable law. Educators may supervise educational use but do not replace parental or lawful-guardian consent where such consent is legally required.

Nature of AI Output: TopicDrop utilizes machine learning and generative artificial intelligence models to synthesize curriculum topics, generate visual diagrams, compose mock examination questions, and provide interactive Socratic tutoring. You acknowledge that generative AI models are probabilistic systems that can hallucinate, omit nuance, or generate inaccurate, incomplete, or mathematically flawed statements.

Educational Aid Only: The Platform is engineered solely as a supplementary study aid. It does not replace classroom instruction, accredited school curricula, teacher mentorship, or textbooks approved by relevant academic examination boards (including CBSE, ICSE, Cambridge Assessment, International Baccalaureate, or state education boards).

Independent Verification: You agree that you are solely responsible for verifying the correctness, curriculum alignment, and factual accuracy of all AI-generated study notes, answers, evaluation rubrics, and formulas before relying on them for graded examinations, homework submissions, or high-stakes academic testing.

High-Stakes Decisions: TopicDrop must not be used as the basis for clinical, medical, legal, safety-critical, or professional decisions.

TopicDrop is intended for educational use and may be used by school-age learners. Where applicable law requires parental or lawful-guardian consent for a user under 18, the required consent must be obtained before the relevant personal-data processing. Parents and lawful guardians are responsible for supervising a minor's use where appropriate.

TopicDrop does not currently claim to operate a comprehensive automated age-verification or parental-verification system. Additional verification or consent controls may be introduced where required by applicable law.

Parents, legal guardians, or educators who introduce learners under 18 to the Service assume responsibility for guiding appropriate study habits, monitoring credit usage, and reviewing study materials.

You agree to provide accurate, current, and complete registration information. Users are responsible for taking reasonable steps to protect their credentials and account security. Nothing in this provision excludes liability or consumer rights that cannot lawfully be excluded.

Google Sign-In: Where you register or sign in using Google OAuth, Google may provide identity information authorized through your Google account (such as name, email address, profile details where authorized, and provider account identifier). TopicDrop does not receive or store your Google password. Your use of Google authentication also involves Google's applicable terms and privacy practices.

You must notify us promptly at ighosh.studio@gmail.com upon discovering any unauthorized access to your account or security breach.

TopicDrop provides free introductory study benefits to allow learners to evaluate the platform's educational quality:

• Starter Bonus Credits: Eligible new user accounts receive 50 Starter Bonus Credits with a 45-day validity period from registration.
• Daily Free Learn Turns: Eligible users receive 10 Daily Free Learn Turns per day for standard interactive study queries.

These starter benefits remain subject to eligibility criteria, fair-use standards, and anti-abuse controls. TopicDrop reserves the right to modify or adjust promotional benefits prospectively for future accounts.

Paid Plans & Credit Packs: TopicDrop offers paid subscription plans (such as Plus and Pro) as well as standalone Study Credit packs for high-volume generation. Prices are clearly displayed in Indian Rupees (INR) at checkout.

Tax Position: Prices displayed on TopicDrop are the current payable amounts. TopicDrop is not currently GST registered and does not separately collect GST; prices remain subject to applicable statutory tax obligations should business status change.

Fulfillment: Subscriptions and purchased credit packs are activated and provisioned immediately upon successful transaction verification by our authorized payment gateway partner (Razorpay).

Subscription Cancellation: Subscribers may cancel recurring subscriptions at any time through available account controls or by contacting support, as applicable. Cancellation stops future renewal charges and does not create partial-period cash refunds for the already-paid billing period. The subscriber retains applicable access to their subscription tier benefits through the end of the active paid period. Mandatory consumer rights remain unaffected.

All commercial transactions on TopicDrop are governed by our dedicated Refund and Cancellation Policy, which is incorporated into these Terms by reference. In the event of any conflict regarding refunds, cancellations, or payment disputes, the Refund and Cancellation Policy shall take precedence.

Utility Metering Token: Study Credits are digital platform tokens used strictly to meter computational processing power, model inference tokens, visual diagram rendering, and handwritten sheet evaluations within TopicDrop.

No Monetary Equivalency: Study Credits have no monetary cash-out value, do not accrue interest, cannot be transferred or assigned between accounts, and cannot be redeemed for cash.

Purchased Extra Credits (Non-Expiring): Purchased Extra Credits purchased under these terms do not expire and remain available until used, subject to account status, applicable law and fraud/abuse controls. Any future change to the validity of newly purchased credit packs will apply only to purchases made after the revised terms are disclosed and will not retroactively shorten the validity of credits already purchased under these terms, except where required by applicable law.

Subscription Plan Credits: Monthly credits allocated under active subscription tiers follow the validity and lifecycle disclosed for the applicable subscription plan, expiring at the end of each billing cycle without rollover.

Failed Generation Protection: No usable result, no final credit loss: system failures are addressed by preventing debits or automatically restoring Study Credits. Where automatic restoration fails, support investigates the Generation ID to restore legitimate credits.

User Content & Ownership: Uploading material to TopicDrop does not transfer ownership of that material to TopicDrop. You retain whatever intellectual-property or other rights you lawfully hold in your User Content. You are responsible for ensuring that you have the necessary rights, permissions or lawful basis to upload and permit TopicDrop to process material that you do not personally own.

Limited Processing License: You grant TopicDrop a limited, revocable, non-exclusive license solely to store, process, analyze, transform, and transmit your User Content to disclosed service providers as reasonably required to deliver requested TopicDrop functionality, customer support, platform security, and other disclosed operational purposes.

User Library Access Controls: Personal User Library materials are access-controlled and associated with the authenticated user's workspace. They are not made available to other ordinary learners or publicly indexed. Authorized TopicDrop systems, personnel and disclosed service providers may process them only where reasonably necessary to provide the Service, support, security or other disclosed purposes.

Prohibited Uploads: You agree not to upload content that infringes third-party intellectual property rights, contains unlawful material, or includes sensitive personal data of third parties without authorization.

TopicDrop distinguishes between private user uploads in the User Library and the platform's curated Knowledge Vault. The Knowledge Vault is TopicDrop's controlled, verified curriculum-source repository containing verified syllabus mappings, textbook references, and pedagogical guidelines.

Private learner uploads do not automatically become shared, public, or verified Knowledge Vault sources. Ingestion into the verified Knowledge Vault occurs only through controlled administrative curation and curriculum verification workflows.

TopicDrop-owned branding, original interface elements, software, content, documentation and other proprietary elements are owned by or licensed to the Operator, excluding third-party/open-source materials governed by their own licenses.

Users are granted a personal, non-exclusive, non-transferable, revocable license to access and use the Platform for educational study. Educators and teachers holding active paid accounts are additionally permitted ordinary, legitimate classroom and educational preparation use of generated learning materials.

When using TopicDrop, you agree not to:

• Reverse engineer, decompile, or extract the source code of the Service;
• Deploy automated scrapers, crawlers, or bots without explicit prior authorization;
• Attempt to bypass rate limits, wallet metering, or security perimeters;
• Submit prompts intended to generate unlawful, defamatory, harassing, abusive, or sexually explicit content;
• Interfere with or compromise the operational stability of the Platform or cloud servers;
• Resell, lease, or commercially exploit platform access without prior written consent.

TopicDrop integrates with established cloud infrastructure and technology providers to deliver its services:

• Cloudflare: Edge routing, DDoS mitigation, and application delivery;
• Supabase: PostgreSQL database hosting and authenticated session handling;
• OpenAI: API-based language model and machine learning processing;
• Razorpay: Payment processing for subscriptions and credit packs.

Data processing by third-party providers is conducted in accordance with our Privacy Policy and applicable provider commercial terms.

We strive to provide reliable and continuous platform access, but do not guarantee uninterrupted, error-free, or zero-latency operation. The Platform may occasionally be unavailable due to maintenance, system updates, or cloud provider disruptions.

TopicDrop reserves the right to modify, enhance, or adjust specific features, user interface layouts, or credit allocations prospectively with reasonable notice to maintain educational quality and technical sustainability.

TopicDrop applies rate limiting and security heuristics to prevent abuse, automated attacks, and fraud.

TopicDrop may restrict or suspend access for verified fraud, abuse, security tampering or serious/repeated Terms violations, subject to applicable law and appropriate review. Suspension preserves wallet, legitimate credit balance, history, and data unless a separate lawful corrective transaction is required.

THE PLATFORM, SERVICES, AI-GENERATED OUTPUTS, AND ALL CONTENT ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR EDUCATIONAL PURPOSE, SYLLABUS COMPATIBILITY, OR ACCURACY. WE DO NOT WARRANT THAT THE SERVICE WILL GUARANTEE SPECIFIC ACADEMIC GRADES, EXAMINATION RESULTS, OR UNINTERRUPTED AVAILABILITY.

To the maximum extent permitted by applicable law, TopicDrop is not responsible for indirect or consequential loss arising solely from reliance on AI-generated educational content or ordinary service interruption. Nothing in these Terms excludes or limits liability, remedies or consumer rights that cannot lawfully be excluded or limited.

You agree to be responsible for your misuse of the Service, your violation of these Terms, or your infringement of third-party intellectual property or privacy rights, subject to applicable law.

These Terms are governed by and construed in accordance with the laws of India, subject to applicable mandatory consumer protection rights and statutory remedies available under applicable law.

These Terms, together with the Privacy Policy and Refund and Cancellation Policy, constitute the legal understanding between you and Indranil Ghosh regarding TopicDrop.
