## 1. About This List {#about}
The Lataamo event platform is operated by Lataamo Group Oy (Business ID: 1652310-5), Espoo, Finland. When an event organizer engages us to run their event, the organizer is the data controller and Lataamo Group Oy acts as the data processor.
To provide the platform, we engage the third-party service providers ("sub-processors") listed below. Every sub-processor is bound by a data processing agreement that meets the requirements of GDPR Article 28, and where personal data is transferred outside the EU, an appropriate transfer mechanism is in place.
This list is published with a full version history. We notify controllers before adding or replacing a sub-processor, as agreed in the data processing agreement, and every change to this list is released as a new version with an effective date and a plain-language change summary — see [Section 4](#changes).

| Lyyti | Event registration import — used only when the event organizer configures registration sync | Registration data (name, email, registration status) | EU (Finland) | No transfer |
| Sentry | Application error and performance monitoring | Technical error reports: stack traces, URLs, browser/OS metadata — personal data scrubbed before send, no IP addresses stored; account and organization metadata | EU (Frankfurt — EU data residency); US (account and organization metadata only) | EU-US Data Privacy Framework + EU Standard Contractual Clauses |
¹ See [Section 3](#ai-regions) for how AI processing regions are governed.
## 3. AI Processing Regions {#ai-regions}
By default, all AI processing runs on EU infrastructure: Google Cloud Vertex AI in the EU (europe-north1 primary, with other EU regions as same-EU capacity fallback and an EU-resident multi-region endpoint), and Mistral AI in France as fallback provider. AI model and provider selection is configurable per event; enabling any non-EU endpoint requires explicit acknowledgment by the event organizer and is logged for accountability. Google's Cloud Data Processing Addendum applies to all Vertex AI endpoints.
## 4. Changes to This List {#changes}
Before adding or replacing a sub-processor, we notify controllers in accordance with the data processing agreement, giving them the opportunity to object.
