Subprocessors
Effective date: 27 October 2026
Who we share data with
Domza relies on a small number of trusted third-party processors to run the service. Each is bound by a data-processing agreement and appropriate transfer safeguards. This page is the authoritative list referenced by our Privacy Policy and the owner Data Processing Agreement.
We will update this page and notify owners by email before adding new subprocessors, so you (as controller of your guest data) can object before new processing begins.
Current subprocessors
| Processor | Role | Region | Data categories | Website | SCC status |
|---|---|---|---|---|---|
| Amazon Web Services (AWS) | Hosting, database, object storage, compute, video conversion | Ireland (eu-west-1) | All operational data at rest: owner accounts, property data, bookings, guest messages, guest registrations and ID-document photos, media, backups | aws.amazon.com | EU region; SCCs in place for any out-of-region support |
| OpenAI | AI model inference: the guest AI concierge and issue detection, message translation and language detection, the owner Help assistant, the property setup assistant, media checks and review-request drafts; once switched on for an owner, reading guest messages received through the owner's PMS to detect departure; voice transcription (whisper-1) when a guest or owner uses the microphone. | United States | Guest and owner message content, the property's AI prompt and the booking context sent with each request, property photos for media checks, and the records an owner's Help question looks up. Once departure detection is on: one guest message received through the PMS at a time, with when it was sent and the planned check-out (the text is not stored by Domza). Voice clips (transcribed, not stored by Domza or OpenAI). API data not used for training; retention per provider terms. | openai.com | SCCs required (US transfer) |
| Anthropic | Reads the identity-document photo a guest uploads during guest registration (is it an ID document, and which fields can be read) | United States | The guest's ID-document photo and the fields read from it (name, date and place of birth, citizenship, document type, series and number). API data not used for training; retention per provider terms. | anthropic.com | SCCs required (US transfer) |
| PostHog | Product analytics (events sent from our servers) | European Union (PostHog EU cloud) | Usage events keyed by internal random IDs (owner, booking, registration) or a hashed email; landing-demo messages with contact details removed. No IP-based location. | posthog.com | EU region; DPA |
| Stripe | Subscription billing for owners | Ireland (Stripe Payments Europe) and United States | Owner email, billing details and subscription status. Card details are entered on Stripe's own checkout page; Domza never sees them. | stripe.com | SCCs required (US transfer) |
| Resend | Transactional email delivery (sign-up, password reset, owner notifications, guest chat links, invoices to guests) | United States | Recipient email address and email content (verification and reset links, owner notifications, a guest's chat link, an invoice the owner sends to a guest) | resend.com | SCCs required (US transfer) |
| Mapbox | Maps and address search when an owner sets a property's location in the dashboard | United States | The address an owner searches for and the map pin's coordinates, plus the owner's IP address (the owner's browser calls Mapbox directly) | mapbox.com | SCCs required (US transfer) |
| Upstash | Serverless Redis: landing-demo cost ledger and per-session message counter | Ireland (eu-west-1) | Daily aggregate cost totals (USD float) and per-session message counters (integers) keyed by an opaque random session ID. No message content, no IP, no user identifiers. | upstash.com | EU region; SCCs in place for any out-of-region support |

Services your own setup chooses
If an owner turns on browser notifications, they are delivered through the push service built into that owner's browser (for example Google, Apple, Mozilla or Microsoft). The notification content is end-to-end encrypted, so the push service cannot read it.
When an owner connects a property management system (PMS) or a booking-platform calendar, Domza reads bookings from that service on the owner's instruction (and, once switched on, the guest messages it received, to detect departure; Domza never writes to the guest's booking platform). That service is the owner's own provider, not a Domza subprocessor.
Transfers outside the EEA
Where a subprocessor operates outside the European Economic Area, the transfer is governed by Standard Contractual Clauses (SCCs) or an equivalent GDPR-approved mechanism, as indicated in the table. Data stored at rest lives in the EU (AWS Ireland).
Changes and contact
When we add, remove, or change a subprocessor, we update this page and notify owners by email before the change takes effect. For questions about this list or to object to a proposed change, contact privacy@domza.ai.
