We use collected information to provide and improve our Services, create and manage user accounts, process orders and subscriptions, provide access to paid content, deliver downloadable digital products, manage cloud storage, verify purchases, prevent fraud, detect unauthorized sharing, provide customer support, send transactional messages, improve website performance, personalize user experience, comply with legal obligations, maintain security, and protect our intellectual property and business interests.

Payments may be processed through third-party payment gateways and financial service providers, including but not limited to PhonePe, Razorpay, PayPal, Stripe, banks, card networks, and other payment processors used by us from time to time.

Payment processors may collect and process payment information according to their own terms and privacy policies. We receive only necessary transaction confirmation, billing, and order-related information required to provide access to purchased products or subscriptions.

Our business provides digital educational content and subscription-based access. To protect paid content and intellectual property, we may monitor download limits, transaction IDs, login sessions, device usage, account sharing patterns, excessive usage, automated scraping, suspicious activity, and violations of our Terms and Conditions.

Where misuse is detected, we may restrict downloads, suspend accounts, revoke access, or take other protective actions permitted by law and our website terms.

Users are responsible for any content they upload. Users must not upload content that is illegal, harmful, infringing, misleading, malicious, confidential without authorization, or otherwise violates third-party rights.

If we offer public library, community sharing, portfolio, project sharing, or similar features, uploaded content may become visible to other users depending on user settings and platform design. We may review, moderate, remove, disable, or restrict content to maintain platform safety and legal compliance.

We may use cookies, local storage, session storage, analytics tools, tracking pixels, server logs, and similar technologies to keep users logged in, secure accounts, remember preferences, analyze traffic, measure marketing performance, detect fraud, and improve our Services.

Users may disable cookies through browser settings, but some website features may not work properly without them.

We do not sell personal information. We may share limited information with trusted service providers only when necessary for business and legal purposes, including payment gateways, hosting providers, cloud storage providers, email service providers, analytics providers, security tools, professional advisors, auditors, government authorities, law enforcement agencies, or courts where legally required.

Cadin360 serves users globally. By using our Services from outside India, you understand and agree that your information may be processed, stored, or transferred in India and other countries where our servers, hosting providers, cloud services, payment processors, analytics tools, or service providers operate.

Data protection laws may differ from country to country. We take reasonable steps to protect information according to this Privacy Policy and applicable legal requirements.

We use reasonable technical, administrative, and organizational measures to protect user information from unauthorized access, misuse, alteration, disclosure, or destruction. However, no website, server, internet transmission, payment gateway, or digital storage system can be guaranteed 100% secure.

Users are responsible for maintaining the confidentiality of passwords, OTPs, login links, devices, and account access. We are not responsible for losses caused by user negligence, shared credentials, compromised devices, phishing, or third-party attacks beyond our reasonable control.

We may retain user information for as long as necessary to provide Services, maintain accounts, resolve disputes, comply with tax/accounting/legal obligations, prevent fraud, enforce agreements, maintain backups, and protect legitimate business interests.

Some records may remain in backups, logs, invoices, payment records, or legal archives even after account deletion, where retention is required or reasonably necessary.

Depending on applicable laws, users may request access to personal information, correction of inaccurate information, deletion of account data, withdrawal of consent, or restriction of certain processing activities. Requests may be sent to our official support email.

We may ask for verification before processing such requests. We may decline or limit requests where retention is required for legal, tax, security, fraud prevention, dispute resolution, or legitimate business purposes.

For users from regions with specific privacy laws, including the European Economic Area, United Kingdom, California, or other jurisdictions, we will make reasonable efforts to honor applicable rights where legally required. Because Cadin360 is operated from India and provides digital educational services globally, users agree that processing may occur in India and through international service providers.

If you require a privacy-related request under your local law, contact us with clear details of your request and your registered account email.

Our Services are intended for general educational and professional learning purposes. Users under the age required by applicable law should use the Services only with consent and supervision of a parent, guardian, teacher, or institution.

If we become aware that personal information has been collected from a child in violation of applicable law, we may delete or restrict such information.

We may send service-related emails, payment confirmations, account alerts, subscription notices, download information, support replies, and important updates. Where permitted, we may also send promotional offers, product updates, learning resources, or platform announcements. Users may opt out of promotional emails, but transactional or legal notices may still be sent.

Our website may contain links to third-party websites, tools, videos, payment pages, marketplaces, social media pages, or external learning resources. We are not responsible for third-party websites, their content, security, or privacy practices. Users should review third-party policies before using those services.

Cadin360 may introduce AI-assisted learning, CAD automation, chatbot support, recommendation systems, file analysis tools, content generation tools, or automated learning features. Such features may process user prompts, uploaded files, usage activity, or learning progress to provide relevant functionality.

Where third-party AI or automation providers are used, information may be processed according to their applicable terms and privacy requirements. Sensitive or confidential files should not be uploaded unless the user has the right and authority to do so.

To the maximum extent permitted by law, Cadin360, its owner, employees, developers, contractors, partners, and affiliates shall not be liable for indirect, incidental, special, consequential, punitive, or business losses arising from use of the Services, data loss, unauthorized access, account misuse, user-uploaded content, third-party services, payment processor issues, downtime, cybersecurity incidents beyond reasonable control, or reliance on educational content.

We may update this Privacy Policy from time to time. The updated version will be posted on our website with a revised date. Continued use of the Services after changes are published means you accept the updated Privacy Policy.

This Privacy Policy shall be governed by and interpreted in accordance with the laws of India. Any dispute, claim, or proceeding arising out of or relating to this Privacy Policy, the website, digital products, subscriptions, user accounts, payments, downloads, uploaded content, or use of the Services shall be subject to the exclusive jurisdiction of the competent courts located in Dwarka, New Delhi, India.

Users agree that no legal action shall be initiated against Cadin360, its owner, employees, contractors, or affiliates in any jurisdiction other than the competent courts of Dwarka, New Delhi, India, to the extent permitted by applicable law.
