Sub-processors

Last updated: September 13, 2026

esek.io provides its service to businesses ("Customers"). When a Customer uses esek.io, the Customer is the controller of the personal data of its own customers, such as messages, calls and contact details ("Customer Data"), and esek.io processes that data on the Customer's behalf. This page lists the third parties that may process Customer Data for us. Customer Data is hosted in the United States. Transfers from the EU, the EEA and the UK rely on the EU-US Data Privacy Framework and Standard Contractual Clauses. How we handle personal data more broadly is described in our Privacy Policy.

1. Sub-processors

These providers process Customer Data on our behalf, only to deliver the service.

Location is where the provider processes the data. Where a provider does not publish a fixed processing region, it is the country of the contracting entity.

2. Services for our own account and billing

esek.io uses these services for its own relationship with Customers, such as billing, sign-in and advertising. For this data esek.io is the controller, and these services do not process the Customer Data described above.

3. Integrations a Customer chooses to connect

A Customer can connect its own accounts with the providers below. The Customer chooses the provider and holds its own agreement with it. We pass data to it only on the Customer's instruction.

4. Changes

We update this page before a new sub-processor starts processing Customer Data, and we email the owner of each workspace at least 30 days in advance. To object to a new sub-processor, contact privacy@esek.io. If we cannot reasonably address the objection, the Customer may terminate the affected service.
