Third-party providers may process information according to their own privacy policies and terms.

6. Advertising Choices and Consent

Depending on your location and applicable law, you may be presented with choices regarding cookies, personalized advertising, or other forms of data processing.

Where legally required, DheetCode will use appropriate consent mechanisms for relevant advertising and analytics technologies.

You may also control certain cookies and tracking technologies through your browser settings.

Blocking or withdrawing consent for certain technologies may affect the availability or functionality of some features.

7. Data Storage and Security

We use reasonable technical and organizational measures intended to protect information handled by DheetCode against unauthorized access, alteration, disclosure, or destruction.

However, no internet transmission or electronic storage system can be guaranteed to be completely secure.

Accordingly, while we take reasonable steps to protect information, we cannot guarantee absolute security.

• Providing the Service
• Maintaining security
• Improving the platform
• Responding to requests
• Resolving disputes
• Preventing abuse
• Complying with legal obligations
• Enforcing agreements and policies

Retention periods may vary depending on the type of information and the reason it was collected.

Information stored exclusively in your browser, such as locally stored AI conversations, may remain there until you or your browser removes it.

9. Sharing of Information

We do not sell or rent your personal information.

We may share or allow access to information in the following circumstances:

10. Third-Party Services and Links

DheetCode may contain links to or integrations with third-party websites and services, including educational platforms, AI providers, analytics providers, advertising providers, and other services.

Examples may include:

• LeetCode
• Google
• Vercel
• Third-party AI providers

These third parties operate under their own privacy policies and terms. DheetCode does not control and is not responsible for the privacy practices of third-party websites or services.

We encourage you to review the privacy policy of any third-party service before providing information to it.

11. International Data Transfers

Some third-party service providers used by DheetCode may process information on servers located outside your country of residence.

For example, information processed by hosting, analytics, advertising, or third-party AI providers may be transferred to and processed in different countries.

Where required by applicable law, appropriate safeguards or legal mechanisms will be used for applicable international transfers.

12.Children's Privacy

DheetCode is an educational platform intended for students and learners.

DheetCode is not specifically directed toward children under the age of 13, and we do not knowingly collect personal information from children under 13.

If you believe that a child under 13 has provided personal information to DheetCode, please contact us. If we determine that we have collected such information, we will take reasonable steps to delete it.

If applicable law in your jurisdiction establishes a different age threshold or additional requirements, those requirements may apply.

These rights may be subject to legal limitations and exceptions.

14. Locally Stored Data

Some DheetCode features may store information directly on your device rather than on DheetCode servers.

Examples may include:

• AI chat history
• Visualizer state
• Preferences
• Learning progress
• Application settings
• Locally generated data

This information may be stored using browser technologies such as Local Storage, IndexedDB, or SQLite WASM.

Because this information is stored locally, DheetCode may not be able to retrieve, restore, or delete it remotely.

You can generally remove locally stored information through your browser's site-data or storage settings.

15. PDF and Local Exports

DheetCode may provide features allowing users to export locally stored information, including AI conversations or learning sessions, into formats such as PDF.

Where implemented as a client-side feature, these exports are generated on your device.

Once you download or otherwise transfer an exported file, its storage and security are your responsibility.

16. Data You Submit to Third-Party AI Providers

If you choose to use an external AI provider through DheetCode, information contained in your prompts may be sent to that provider.

For example, a prompt may contain:

• Your question
• A programming problem
• System-design information
• Visualizer state
• Code you provide
• Other contextual information required to answer your request

You should avoid submitting passwords, authentication credentials, API keys belonging to other services, financial information, or other sensitive information unless you understand the risks and the relevant provider's policies.

The handling of information by the selected AI provider is governed by that provider's own policies.
