In short

  • Hosting and databases: DigitalOcean, in Frankfurt. Media storage: Google Cloud, also in Frankfurt.
  • Cloudflare protects every relay address and carries its traffic. Payments, error reporting, analytics and email each go through one provider.
  • The proxy provider only handles numbers that use the optional proxy add-on.
  • WhatsApp (Meta) is not our sub-processor: your numbers connect as your own linked devices.
  • We announce new sub-processors [SUB-PROCESSOR NOTICE PERIOD] before they start.

This summary helps you find your way; the full text below is what applies.

1Our sub-processors

relay uses these companies to run the service. Each one processes personal data only to provide its part of the service, under a written agreement with data protection terms [CONFIRM CONTRACTS].

Our infrastructure also relies on services that receive no personal data from you or your contacts, such as our code and container image hosting and the authority that issues our HTTPS certificates. They are not listed here.

2WhatsApp and Meta

WhatsApp (Meta) is not a sub-processor of relay. Your numbers remain your own WhatsApp accounts: relay connects to them as a linked device, the way WhatsApp Web does, at your request.

The messages you exchange travel through WhatsApp under your own relationship with WhatsApp, governed by its terms and privacy policy, not under a contract between relay and Meta.

relay is not affiliated with WhatsApp or Meta.

We will tell you about a new sub-processor at least [SUB-PROCESSOR NOTICE PERIOD] before it starts processing personal data, by [NOTICE CHANNEL].

To be told about changes: [SUBSCRIBE MECHANISM].

If you object to a new sub-processor on reasonable data protection grounds, you can raise it as set out in the Data Processing Agreement.
