Subprocessors
Last updated: November 13, 2026
This page lists the third-party service providers (“subprocessors”) that process personal data on our behalf when you use YouTube Comments Downloader. It forms part of our Data Processing Agreement.
We are Undefined Bartosz Igielski, a sole proprietorship registered in the Polish business register (CEIDG), VAT ID PL6172207546, REGON 363119493. You can contact us at contact@youtubecommentsdownloader.com.

| Hetzner (Hetzner Online GmbH) | API servers, Redis, the PocketBase database, stored download files, and our self-hosted Listmonk newsletter and n8n workflow tools | All data needed to provide the Services, including the content you request and export | EU (Falkenstein and Nuremberg, Germany) |

| MailerSend (MailerSend, Inc.) | Product announcement emails | Email address and name | EU and the United States |
Listmonk and n8n are self-hosted tools that run on our Hetzner servers, so they are covered by the Hetzner row rather than listed as separate vendors.
When you connect an AI app or another tool through our MCP server or API, that app is not our subprocessor. It acts on your instructions and its own terms and privacy policy apply. The same is true for anyone you share a download or export link with.
We may change this list from time to time. When we add or replace a subprocessor, we update this page and change the “as of” date above. We aim to publish the update before the new subprocessor starts processing personal data. Business customers can object to a change as described in the Data Processing Agreement.
