Sub-processor Register

Last updated: 12 czerwca 2026

1. Purpose & scope

This register lists the third parties ("sub-processors") that Akkadian ("Chatvia") engages to process personal data on behalf of its customers in the course of operating the Chatvia service. It satisfies the transparency and prior-authorisation obligations of GDPR Article 28(2)–(4) and accompanies the customer-facing Data Processing Agreement (DPA).

Controller / processor split. Chatvia is a processor under GDPR Article 4(8). Each customer workspace is the controller (Article 4(7)) of the personal data its embedded widget collects — conversation transcripts, captured contact details ("Leads"), and uploaded knowledge-base documents. Where a sub-processor receives that data, it acts as a sub-processor engaged by Chatvia under Article 28(4), bound by data-protection terms no less protective than those Chatvia owes the controller.

This register covers only sub-processors on the production data path — parties that may access, store, or transmit customer personal data. It does not list every vendor configurable in the codebase. A workspace's optional integrations (e.g. its own MCP connectors or OAuth tools) are sub-processors of that workspace's data only when the workspace enables them, and are out of scope here.

2. Data residency — EU only

Chatvia's production sub-processor chain for personal data is established and operated within the European Union. Core compute and the database run on Hetzner in Germany; AI inference, object storage, database backups, and transactional email run on Scaleway in France. The remaining EU sub-processors are EU companies.

Two sub-processors have a non-EEA (US) nexus, both covered by the EU Standard Contractual Clauses (GDPR Chapter V):

  • Stripe (US parent) for payment processing, under Stripe's Data Processing Agreement; and
  • Firecrawl (US) for crawling public websites only. Firecrawl is used solely to fetch publicly accessible web pages a workspace chooses to add to its knowledge base. It receives only the public URL and returns the public page content — no conversation transcripts, Leads, end-user personal data, or private/login-protected content ever reach it. Because only public web content is sent, no customer personal data leaves the EU through Firecrawl.

No training on inference data. Chat content transmitted to Scaleway for inference is not used to train Scaleway's or any third party's models. Inference is transient: prompts and completions are processed only to return a response and are not retained for model improvement.

3. Sub-processors

Hetzner Online GmbH — Germany (EU)

  • Purpose: Primary infrastructure — compute servers, the database, and supporting services (cache, queues).
  • Data processed: Live application data at rest — conversation transcripts, Leads (contact details), knowledge-base documents, vector embeddings, and encrypted application data.
  • Data Processing Agreement: https://www.hetzner.com/legal/data-processing

Scaleway SAS — France (EU)

  • Purpose: AI inference (open-weight models); object storage of attachments and exports; database backups (in a separate bucket); transactional email.
  • Data processed: Conversation content submitted for inference (may include visitor PII); knowledge-base attachments and exports; database backup archives; and email recipient address, name, and message content.
  • Data Processing Agreement: https://www.scaleway.com/en/contracts/

Stripe — Ireland (+ US parent, SCCs)

  • Purpose: Subscription billing and payment processing.
  • Data processed: Workspace billing identity, email, and card data (held by Stripe; Chatvia stores no card number — only Stripe customer/subscription identifiers).
  • Data Processing Agreement: https://stripe.com/legal/dpa

Bunny.net (BunnyWay d.o.o.) — Slovenia (EU); global edge

  • Purpose: CDN / edge delivery of static assets and the embeddable widget script.
  • Data processed: Visitor IP address, user-agent, and request metadata in transit.
  • Data Processing Agreement: https://bunny.net/dpa

Plausible Insights OÜ — Estonia (EU)

  • Purpose: Privacy-friendly, cookieless website and product analytics.
  • Data processed: Aggregated usage events. No cookies, no cross-site tracking, and no storage of directly identifying personal data by design.
  • Data Processing Agreement: https://plausible.io/dpa

Flare (flareapp.io) — Belgium (EU)

  • Purpose: Application error and exception monitoring.
  • Data processed: Diagnostic / exception data, which may incidentally include user identifiers or request context within stack traces.
  • Data Processing Agreement: https://flareapp.io/

Firecrawl (firecrawl.dev) — United States (SCCs)

  • Purpose: Crawling and fetching public web pages when a workspace adds a public website as a knowledge-base source. Firecrawl retrieves the publicly accessible page and returns its text so it can be indexed for the agent.
  • Data processed: Only the public website address (URL) the workspace chooses to crawl, and the public page content Firecrawl returns. Firecrawl receives no conversation transcripts, Leads, end-user personal data, account data, or private/login-protected content — it reads only pages that are already public on the open internet.
  • Transfers: US-based; relies on the EU Standard Contractual Clauses (GDPR Chapter V). As only public web content is transmitted, no customer personal data is transferred.
  • Data Processing Agreement: confirm current DPA/terms at https://www.firecrawl.dev/

DPA links are provided for reference; confirm the current link and terms with each provider at onboarding and at each annual review.

Excluded — not sub-processors. Internal monitoring tools that run inside Chatvia's own infrastructure without sending customer personal data to a third party are not sub-processors and are excluded from this register.

4. Sub-processor governance

Chatvia applies the following controls to every sub-processor under Article 28:

  • Written terms. Each sub-processor is engaged under a DPA (or equivalent terms) imposing data-protection obligations no less protective than Chatvia's own, including confidentiality, security, and assistance duties (Art. 28(3)).
  • EEA-first selection. Sub-processors are selected to keep processing within the EEA wherever feasible — Hetzner (Germany) and Scaleway (France) for all core hosting, storage, inference, and email. Where a sub-processor has a non-EEA nexus (Stripe for payments; Firecrawl for public-website crawling), the transfer relies on an adequacy decision or EU Standard Contractual Clauses (Art. 46). Firecrawl receives only public web content, never customer personal data.
  • Security diligence. Sub-processors are assessed for technical and organisational measures appropriate to the data (Art. 32) before activation.
  • Solo-operator compensating control. Chatvia is run by a sole founder/engineer. Sub-processor changes are made exclusively through version-controlled configuration (PR + CI + immutable Git history), and the active set is re-validated at each annual review and at every material change. This documented review substitutes for segregation-of-duties.

5. Change notification & objection (Article 28(2))

Chatvia maintains this register as the canonical, published sub-processor list and commits to:

  • 30 days' advance notice of any intended addition or replacement of a sub-processor that will process customer personal data, via this document and/or the customer notification channel on record.
  • A right to object during that notice window. A controller may object on reasonable, data-protection-related grounds by writing to [email protected]. Chatvia will work in good faith to address the objection; where it cannot, the controller may terminate the affected service as set out in the DPA.
  • Emergency changes. If a sub-processor must be replaced sooner to address a security or availability risk, Chatvia will notify affected controllers without undue delay and document the justification.

Contact. Sub-processor enquiries, objections, and DPA requests: [email protected]. Security matters: [email protected]. Registered operator: Akkadian, Skovbrynet 50, 1 tv, Næstved, Denmark, governed by the laws of Denmark.

6. Framework mapping
