Privacy Policy

1. About Z2H

Z2H by PKB is an educational learning platform. Z2H AI provides AI-assisted educational explanations, learning support and related account features. This policy applies to the Z2H website, Z2H account interactions, Z2H AI learning interactions, WhatsApp-based access and support communications covered by Z2H.

2. Information we may process

The information processed depends on the features you choose to use.

Account and registration information

• Your name, registered mobile number, email address or other account identifiers, where applicable.
• Account verification, Admin approval and access status.
• Authentication and session information needed to keep account features working securely.

WhatsApp information

• The mobile number used to contact Z2H through WhatsApp.
• Messages, questions, files or other content you choose to send.
• Message timestamps, delivery details and interaction metadata made available through the messaging platform.

AI and learning information

• Student Memory, learning preferences, completed topics and learning progress where those features are enabled.
• Context needed to continue a requested learning interaction or provide a more relevant educational response.

Forms, support and applications

When you contact support or submit a website form, we may process the details you provide. For a career application, this may include your name, email, phone number, location, experience, portfolio, message and uploaded CV.

Technical and security information

We may process IP address, browser or device information, request timestamps, pages or features accessed, error records, authentication attempts and security or abuse signals. This helps us operate, diagnose and protect the service.

Cookies, sessions and browser storage

We use session data where needed for authenticated features. The website may also use browser storage for settings such as language preference and limited interaction preferences. These technologies support site operation, continuity and security.

3. Why we use information

We may use information to:

• Create, manage, verify and secure user accounts.
• Authenticate users and maintain secure sessions.
• Link WhatsApp access to the registered mobile number associated with a Z2H account.
• Process messages and provide the Z2H AI educational response requested by the user.
• Support Student Memory, learning preferences and progress where applicable.
• Respond to support, privacy and career-related requests.
• Maintain, troubleshoot and improve website and educational features.
• Detect and prevent fraud, abuse, unauthorized access and other security risks.
• Meet applicable record-keeping or legal requirements where necessary.

5. AI-assisted educational interactions

Z2H AI may process a user's message, relevant conversation context and enabled learning preferences to generate an educational response. AI-generated responses may not always be complete or accurate, so important information should be independently checked.

Where Student Memory is enabled, relevant learning preferences or progress may be retained to support continuity. The available controls and stored details may depend on the account feature being used.

6. Service providers, disclosure and access

We may use service providers only where reasonably needed to operate and protect Z2H, including:

• Messaging and platform infrastructure providers.
• AI technology and service providers.
• Hosting and security providers.

These providers may process limited information on our behalf for the relevant service function. We may also disclose information when reasonably necessary to comply with applicable law, respond to a valid legal process, protect users or protect the security and integrity of Z2H.

Z2H does not sell personal data. Access to personal information is limited to legitimate service, support, operational and security purposes.

7. Data retention and security

Retention

We retain information only for as long as reasonably needed to provide the relevant service, maintain account and security records, respond to support or disputes, prevent abuse and meet applicable legal requirements. Retention may vary according to the type of information and why it is needed.

Security

We use reasonable administrative and technical measures designed to protect information, including access restrictions, account and session controls, and security monitoring where applicable. No online service or storage method can guarantee absolute security.

8. Your choices and requests

You may ask us to review or correct relevant account information, unlink WhatsApp access, or delete account-related personal information. We may need to verify your identity and registered mobile number before acting on a request.

Some information may need to be retained where reasonably necessary for security, fraud prevention, record-keeping, dispute handling or applicable legal requirements.
