Understanding Subprocessors

Not Every Third Party Is Automatically a Subprocessor.

The role depends on what the third party does, whose instructions it follows and whether it processes relevant personal data on behalf of HotelConnect24 within the applicable processing relationship.

Subprocessor

A provider may act as a subprocessor where it processes relevant personal data on behalf of HotelConnect24 in a processing chain where HotelConnect24 itself acts as a processor.

Independent Service Provider

Some third parties may determine their own purposes for particular processing activities rather than acting only on HotelConnect24 instructions. Their legal role can therefore differ.

External Integration Partner

A hotel, OTA, distribution business or technology partner can participate in a connected workflow without necessarily being a HotelConnect24 subprocessor. The relationship depends on the actual data flow.

Current Register

HotelConnect24 Subprocessor Register.

The register below identifies providers currently known to support HotelConnect24 services that can involve processing of relevant information. The exact processing depends on which service is enabled.

Processing Context Where configured
Register note: A provider's appearance on this page does not mean that every HotelConnect24 user's information is sent to that provider, nor that every service listed is used in every workflow. Processing depends on the HotelConnect24 service, technical configuration and applicable data flow. This register should be updated whenever the production architecture changes materially.
Processing Relationships

Follow the Data Flow — Not Just the Vendor Name.

The same provider can have different legal and operational roles depending on the service being used. HotelConnect24 therefore needs to understand what information is processed, why it is processed and under whose instructions.

This is particularly important when HotelConnect24 processes data on behalf of a hotel and then uses another service provider to support that processing.

✓
Identify the purpose Understand why the provider is needed for the HotelConnect24 service.
✓
Identify the data Determine which information the provider can actually receive or access.
✓
Identify the role Determine whether the provider acts as processor, subprocessor, independent controller or another role.
✓
Document the relationship Relevant contractual and data-protection requirements should reflect the actual processing arrangement.

International Processing

Provider Location and Data Location Are Not Always the Same Thing.

A technology provider can be headquartered in one country, operate infrastructure in another and use support or corporate systems across multiple jurisdictions.

HotelConnect24 should therefore evaluate relevant international data flows based on the actual service and contractual arrangement rather than relying only on the provider's brand address.

✓
Review service regions Understand where relevant production services and data processing can occur.
✓
Review contractual safeguards Where required, appropriate contractual transfer mechanisms should be considered.
✓
Prefer appropriate regional configuration Where available and suitable, regional service configuration can help reduce unnecessary international processing.
✓
Keep the register current Material changes to providers or processing locations should be reflected in the relevant documentation.
International Processing Review Questions to consider before production use
01
Where Is the Service Hosted? Identify the relevant infrastructure or service region.
02
Who Can Access the Data? Consider provider personnel and service operations where relevant.
03
What Data Is Required? Limit the provider's exposure to information needed for the service.
04
What Contract Applies? Review the applicable processing and transfer terms.
05
Has the Register Been Updated? Keep customer-facing information aligned with production reality.
Provider Review

A Useful Tool Is Not Automatically the Right Production Provider.

Before a service becomes part of a HotelConnect24 production workflow, its purpose, data access and operational importance should be understood.

01 Business Need Confirm that the provider solves a real operational or technical requirement.
02 Data Scope Identify the minimum information the provider needs to deliver its service.
03 Security Consider relevant security controls and the sensitivity of the processing involved.
04 Location Understand relevant service regions and international processing implications.
05 Contract Review the applicable terms and data-processing provisions where required.
06 Reliability Consider how provider failure could affect important HotelConnect24 workflows.
07 Access Limitation Configure the service so it receives only the permissions and information it actually needs.
08 Register Update Document the provider publicly where it falls within the applicable subprocessor register.
Changes to Subprocessors

The Register Must Be Able to Change with the Platform.

HotelConnect24 may add, replace or remove service providers as the platform evolves. The production register should reflect material changes to relevant processing dependencies.

Add

New Provider

A new provider may be introduced where HotelConnect24 requires a new service, improves the architecture or replaces an existing dependency.

Update

Changed Processing

An existing provider's purpose, service region or data-processing scope may change as the HotelConnect24 implementation evolves.

Remove

Retired Provider

Providers should be removed from the active register when they no longer support the relevant HotelConnect24 processing activity.

Change notice: Where a contract or applicable data-processing agreement requires specific notice of a new subprocessor, that notice mechanism should be handled according to the relevant agreement. Publication on this page is intended to support transparency but does not replace a separately required contractual notification process.
What Is Not Included

A Connected Business Is Not Necessarily a HotelConnect24 Subprocessor.

HotelConnect24 can connect with hotels, distribution platforms, technology providers and travel businesses that operate under their own independent roles and responsibilities.

Hotels

A participating hotel is not listed here merely because it exchanges reservation or property information with HotelConnect24.

Distribution Partners

OTAs, travel marketplaces and distribution businesses can have their own independent relationship with travellers and hotels.

Technology Partners

An integrated technology company is not automatically a subprocessor. Its role depends on the actual processing arrangement and data flow.

Practical Scope

The Register Should Follow Production Reality.

Infrastructure and integrations can change. A subprocessor page is useful only when it is maintained alongside the actual HotelConnect24 architecture.

Important: This page provides general transparency regarding HotelConnect24 third-party service providers and subprocessors. The exact legal role of a provider depends on the relevant processing activity, contractual relationship and applicable law. A provider listed here may not process data for every HotelConnect24 customer or service. Additional providers may be used for specific products or configurations and should be added to the register where required. Specific contractual obligations are governed by the applicable HotelConnect24 agreement and Data Processing Agreement.
Subprocessor FAQ

Common Questions About HotelConnect24 Subprocessors.

What is a subprocessor?
A subprocessor is generally a third-party provider engaged by a processor to process relevant personal data on behalf of that processor. The exact role depends on the applicable processing relationship and contract.
Why does HotelConnect24 use external providers?
Specialist providers can support infrastructure, email delivery, security and other technical functions that are needed to operate HotelConnect24 services effectively.
Does every HotelConnect24 user send data to every provider listed here?
No. Processing depends on the service being used, technical configuration and relevant workflow. A provider can be part of the HotelConnect24 architecture without receiving data from every user or property.
Does HotelConnect24 currently use Hetzner?
Hetzner infrastructure is used for relevant HotelConnect24 web or server workloads in the current architecture. The exact role can change as the production infrastructure evolves.
What is SMTP2GO used for?
SMTP2GO is used where configured to support transactional or operational email delivery. This can involve recipient email addresses, message content and delivery-related technical information required to send the relevant communication.
Why is Cloudflare listed?
Cloudflare services may be used where configured for security, anti-abuse or human-verification functionality such as Turnstile. The exact information processed depends on the enabled service and workflow.
Are Booking.com or other distribution platforms HotelConnect24 subprocessors?
Not automatically. A distribution partner may operate under its own independent role and commercial relationship. Whether an organisation is a subprocessor depends on the actual processing arrangement, not simply on the fact that systems exchange booking information.
Are all technology partners subprocessors?
No. An integration alone does not determine the legal role. Technology partners may act under different processing relationships depending on the service and data flow.
Can HotelConnect24 add new subprocessors?
Yes. HotelConnect24 may add or replace providers as the platform evolves. Relevant production changes should be reflected in this register and, where required, handled according to applicable contractual notice provisions.
Can a subprocessor be located outside the European Economic Area?
Depending on the provider and service, international processing may be possible. Relevant service regions, contractual safeguards and transfer requirements should be considered according to the actual processing arrangement.
Where can I read more about HotelConnect24 data protection?
See the HotelConnect24 Data Protection page, Privacy Policy and Data Processing Agreement for further information about data handling and business processing relationships.
