Privacy Policy

Last updated: 2 April 2026

Expert Hub is a marketplace platform for experts and users. This Privacy Policy explains what information we collect, how we use it, and how we protect it when you use our website, Telegram-related flows, wallet connection features, and calendar connection features.

1. Information we collect

We may collect the following categories of information:

• Account and profile information, such as your Telegram ID, username, display name, profile photo, and profile description.
• Wallet-related information, such as connected TON wallet address and network information.
• Calendar connection information, such as Google account email, selected calendar identifiers, and related connection metadata.
• Booking and marketplace activity, such as expert profile settings, availability, requests, confirmations, and reviews.
• Technical information, such as IP address, browser type, device data, session data, logs, and interaction events needed for security and operation.

2. How we use your information

We use information to:

• operate the Expert Hub platform;
• authenticate users and experts;
• create and manage expert profiles;
• process wallet connections and marketplace actions;
• connect and sync calendar-related availability data;
• improve security, detect abuse, and prevent fraud;
• communicate with users about platform functionality and support matters.

3. Google Calendar data

If you connect Google Calendar, Expert Hub may access calendar-related data that is required to support availability selection, booking logic, and related scheduling features. We only use this access for functionality directly related to the platform.

We do not sell your Google user data. We do not use Google Calendar data for advertising.

4. Telegram and wallet data

If you use Telegram authentication or Telegram Mini App flows, we may process the Telegram account data provided during that flow. If you connect a TON wallet, we may store the public wallet address and related technical metadata needed for platform operation.

5. Data sharing

We may share limited data only when necessary:

• with infrastructure or service providers that help operate the platform;
• when required by law, regulation, legal process, or valid governmental request;
• to protect the rights, security, and integrity of the platform and its users.

We do not sell personal information to third parties.

6. Data retention

We retain information for as long as needed to operate the service, comply with legal obligations, resolve disputes, and enforce platform rules. Some technical logs and backup records may remain for a reasonable period even after account deletion or disconnection.

7. Security

We use reasonable technical and organizational measures to protect information against unauthorized access, loss, misuse, or alteration. No system is perfectly secure, and we cannot guarantee absolute security.

8. Your choices

Depending on the feature, you may be able to:

• edit your expert profile information;
• disconnect your wallet;
• disconnect your calendar integration;
• stop using the platform at any time.

9. Children

Expert Hub is not intended for children under the age required by applicable law to use this kind of service independently.

10. Changes to this policy

We may update this Privacy Policy from time to time. Updated versions will be posted on this page with a new effective date.
