PRIVACY POLICY (Individual Version)

Effective Date: February 8, 2026
Data Controller: Kulniev Roman, Individual Entrepreneur
Trading As: ProChinaSource
Contact: privacy@prochinasource.com
Registered Address: For address contact privacy@prochinasource.com

1. Introduction

I operate ProChinaSource as an individual entrepreneur (sole proprietor). This means I personally am responsible for the processing of your personal data on this B2B lead generation platform.

Legal Status: While I operate under the brand "ProChinaSource", legally this is a personal business activity. All obligations, liabilities, and responsibilities described herein apply to me personally as the data controller.

2. Data I Collect

2.1 Account Information

  • Email address, full name/company name
  • Role (Client or Provider)
  • Business details (for B2B matching purposes)

2.2 Tender & Contact Data

When you post a tender, I collect contact details (email, phone, messenger IDs).
Important: This data is stored in secure cloud databases (Supabase) protected by industry-standard measures, but is not encrypted at the column level (see Section 5).

2.3 Technical Data

IP address, browser info, usage analytics (via Vercel/Supabase).

3. Legal Basis (GDPR)

As an individual processing data of EU residents, I rely on:

  • Contract (account creation)
  • Legitimate Interest (B2B lead generation — sharing contacts with paying Providers)
  • Consent (email notifications, withdrawable anytime)

4. How I Share Your Data

4.1 With Other Users

When a Provider pays $10, I personally authorize the system to share your contact details with that specific Provider. This is the core service.

4.2 With Subprocessors (My Tools)

I use these services to operate the platform:

ServiceMy RelationshipYour Data There
SupabaseData hostingDatabase storage
PaddlePayment processor (they are Merchant of Record)Payment data only
ResendEmail deliveryEmail addresses
VercelHostingAccess logs

Note: These are business tools I use personally. They have their own Privacy Policies and DPA agreements with me.

5. Data Security & Important Disclosure

As an individual operator, I implement:

  • TLS 1.3 encryption (data in transit)
  • Strong passwords and 2FA on all accounts
  • Access limited to me personally (no employees)

Critical Technical Limitation:
I do not currently use field-level encryption (Supabase Vault). Your email and contact details are stored in the database in a format that I, as the administrator, can technically access. While I never do this without legal necessity, you should understand that:

  • I can see email addresses in the admin panel
  • In case of a database breach, contact details would be exposed
  • I am working on implementing column-level encryption in future updates

6. Your Rights

You have full GDPR rights (access, deletion, portability). To exercise them, email me personally at privacy@prochinasource.com. I will respond within 30 days as required by law.

Account Deletion: You can request deletion at any time. I will delete your data within 7 days, except:

  • Purchase records (kept 7 years for tax authorities)
  • Contacts already shared with Providers (cannot be deleted from their devices)

7. International Transfers

I may process data in:

  • EU/US (Supabase/Vercel) — covered by Standard Contractual Clauses
  • UK (Paddle payments)

As an individual, I rely on the same SCCs that companies use.
