Privacy Policy

Last updated: 10 May 2026.

1. Data controller

The data controller is 4D Growth Advisory ("4D", "we"), the operator of 4dgroup.hu and its Mini-Diagnosis service. Contact for privacy matters: hello@4dsalesarchitecture.com Registered office and company details: see the Imprint page for full corporate information.

2. Data we collect

When you use the Mini-Diagnosis we collect the following data from you:

  • The URL of your company website and (optionally) the LinkedIn URL of the leader you submit for the diagnosis
  • Your email address, so we can deliver the diagnosis result and its permalink
  • The timestamp of the request, your IP address and User-Agent header — for abuse prevention and technical logging
  • The output of the Mini-Diagnosis (classification, narrative summary, public signals collected during processing)

3. How we use the data

  • Run the Mini-Diagnosis and deliver the result to you by email
  • Make the result available via a stable, shareable permalink
  • Prevent abuse (bot traffic, excessive request volume) and maintain technical stability
  • Produce aggregated, anonymised statistics to improve the quality of the service

4. Legal basis

We process your data on the following legal bases: • Performance of a service you requested (GDPR Art. 6(1)(b)) — running the Mini-Diagnosis and delivering the result. • Legitimate interest (GDPR Art. 6(1)(f)) — abuse prevention, security logging, and aggregate quality measurement. For any marketing communication (e.g. newsletter) we ask for separate consent. Submitting a Mini-Diagnosis does not constitute such consent.

5. Recipients and processors

To run the diagnosis, the URLs you submit and the public data we collect during processing are forwarded to the following providers, only to the extent necessary to deliver the service:

  • Anthropic (USA, EU residency available) — language model for analysis
  • OpenAI and Perplexity (USA) — language models for market visibility checks
  • Google (Maps Platform, Search) — public reviews and search results
  • DataForSEO (USA) — search-engine result data
  • Meta (Ireland) — Meta Ad Library API queries to determine paid-media activity
  • Webshare (USA) — proxy network for fetching public LinkedIn profiles
  • Supabase (EU region) — result storage
  • Resend (USA) — transactional email delivery
  • Vercel (USA) and Hetzner (DE) — hosting of the website and the diagnostic engine
  • Coolify — deployment surface for the diagnostic engine on Hetzner

6. International transfers

Some of the providers listed in section 5 are based outside the European Economic Area (primarily the USA). We work with those providers under Standard Contractual Clauses or under an adequacy decision of the European Commission (e.g. the EU–US Data Privacy Framework).

7. Retention

  • Diagnosis results and submitted URLs: 24 months
  • Email address (linked to the corresponding result): 24 months, or until you request deletion
  • Technical logs (IP, User-Agent, request timestamp): up to 90 days
  • Aggregated, non-identifying statistics: kept indefinitely

8. Your rights

Under the GDPR you may at any time exercise the following rights:

  • Access to the personal data we hold about you
  • Rectification if the data is inaccurate or incomplete
  • Erasure ("right to be forgotten") subject to applicable conditions
  • Restriction of processing
  • Data portability — receive your data in a machine-readable format
  • Object to processing based on legitimate interest

9. How to exercise your rights
