This page describes how CryptoWalk handles personal data in the current application setup.

Controller

  • CryptoWalk is operated by Jan Cornels, Königswiesen 1, 21147 Hamburg, Germany.

What This Site Processes

  • Account and authentication data for registered users through Supabase, including email address and session-related data.
  • Organizer application data that users submit, including name, email, city, area, motivation, and any duplicate-city explanation they choose to provide.
  • City and walk management data entered by approved organizers or admins, such as descriptions, Telegram links, Meetup links, and scheduling details.
  • Public city and event information that is displayed on the site once published.
  • Technical request and security data that is necessary to deliver the site and protect the service.

Why The Data Is Used

  • To run the website and authenticate users.
  • To review organizer applications and manage organizer access.
  • To publish city pages and event information.
  • To send organizer-related notification emails when that workflow is triggered.
  • To maintain the security, stability, and integrity of the service.

Service Providers and External Services

  • Supabase is used for authentication, database storage, and related backend functions.
  • Vercel is used to host and deliver the application.
  • Cloudflare is used for DNS, TLS, and security at the domain perimeter.
  • Google Places and Google Maps services are used to search and verify city locations and to generate map links or map imagery where applicable.
  • Meetup is used as an external source for community and event links and for event synchronization where configured.

Cookies and Tracking
