Last updated: 10 November 2026 · Version 2026-11-10

The providers that process personal data on behalf of Onesta (Romania Business Labs SRL): who they are, what they do and where. For the data of a firm's clients the firm is the controller, Onesta is the processor and those below are sub-processors, under the data processing agreement in the Terms. We publish changes to the list on this page.

1. Hosting

Railway Corporation: hosting of the application and the database, in Railway's EU West region (European Union).

2. Email

Resend: delivery of the emails Onesta sends — invitations, notifications and messages about the account.

3. Payments

Stripe: collecting the firm's subscription.

4. Usage analytics

PostHog Inc., EU cloud (data stored in Germany): on the site and in the app, only with your consent.

5. The AI team

MARQL LTD (marql, a product of the same team; based in the United Kingdom, data stored in the European Union): running the AI team's assistants, only for the firms that use it.

We name the AI model provider marql uses on request, at contact@onesta.app.

6. Phone notifications

Apple (Apple Push Notification service) and Google (Firebase Cloud Messaging): delivery of notifications in the Onesta phone app, only if you turn them on.

7. Transfers and questions

If a provider processes data outside the European Economic Area, it does so only with appropriate safeguards: an adequacy decision or the standard contractual clauses approved by the European Commission.
