Privacy Policy

Last updated: May 11, 2026

1. Introduction

This Privacy Policy describes how ERARTA FZE ("we", "our", "Zer0") collects, uses, and protects the personal data of users of the Zer0 Dietitian Dashboard web service available at app.c0r.ai. By using the service, you confirm that you have read and understood this Policy. If you do not agree with its terms, please do not use the service.

2. What data we collect

We collect: account data (email, name, dietitian specialty, years of experience), client profile data (sex, age, height, weight, nutrition goals), food diaries (meal photographs, AI-recognised dishes, calories, macronutrients), weight history, check-ins, dietitian-client messages, payment metadata (we never store card numbers — they are handled by our payment providers YooKassa or Tinkoff). We do NOT collect bank card numbers, passport data, or biometric data. Technical data (IP address, browser type, visit time) is logged by Vercel and Supabase using standard server logs.

3. How we use your data

We use your data solely to: provide the service functionality (display clients, food diaries, analytics, dietitian-client chat), process payments and subscriptions, ensure security (detect fraud and abuse), and send transactional notifications (payment status changes, important policy updates). We do NOT share your data with third parties for marketing purposes and we do NOT sell it.

4. Legal basis for processing

The legal bases for processing personal data are: your consent (Art. 6 of Russian Federal Law No. 152-FZ; GDPR Art. 6(1)(a)), performance of the service agreement (GDPR Art. 6(1)(b)), legitimate interest in keeping the service secure and operational (GDPR Art. 6(1)(f)), and compliance with legal obligations (GDPR Art. 6(1)(c)). Consent can be withdrawn at any time by deleting your account.

5. Where your data is stored (152-FZ)

Your personal data is stored in the secure Supabase infrastructure (project mmrzpngugivxoapjiovb) in the eu-central-1 region (Germany). Cross-border transfer of data from the Russian Federation is carried out on the basis of your consent under Article 12, Part 1, Paragraph 1 of Federal Law No. 152-FZ "On Personal Data". By creating a Zer0 account, you confirm your informed consent to the cross-border transfer of personal data to Germany (a country providing an adequate level of protection per the European Commission and the Roskomnadzor registry). Backups are stored in the same EU region.

6. Controller and processors

Data controller: ERARTA FZE (Dubai Multi Commodities Centre, UAE) — determines the purposes and means of processing. Processors (acting on behalf of the controller): Supabase Inc. (database hosting and authentication), Vercel Inc. (web application and edge function hosting), YooKassa / Tinkoff (payment processing for Russian residents), Resend (transactional email delivery). All processors are bound by Data Processing Agreements.
