Subprocessors

Last updated 23 October 2026

Running Determesh needs other companies. The AI has to run somewhere, email has to be delivered by somebody, and the website has to be served. Each of these companies can, in the course of its job, touch personal data that belongs to a company using Determesh, or to us. That makes them subprocessors, and this is the whole list.

It is published rather than offered on request because a company deciding whether to trust us with its users' data should see who else is in the chain before it asks.

The list

DeepSeek

Hangzhou DeepSeek Artificial Intelligence Co., Ltd. · China

The AI models. Receives the parts of a conversation the AI needs to work out an answer: the message, the conversation so far or a summary of it, passages from the company's documents, what the company's systems returned, and the user's note on how they like to be answered.

Zoho (ZeptoMail)

Zoho Corporation · India

Delivers the emails Determesh sends: account emails, and emails a company's systems ask Determesh to send. Sees the recipient's address and the contents of the message.

Telegram

Telegram Messenger · global

Carries messages between a company's Telegram bot and its users, where a company connects one. Sees those messages, as with any Telegram chat.

Amazon Web Services

Amazon Web Services · United States (us-east-1) and its global network

Serves this website and the control panels, carries traffic to the API through its network, and runs our DNS and certificates. Requests to the API pass through it on their way to our servers.

Hetzner

Hetzner Online GmbH · Helsinki, Finland

Runs our contact form gateway, and the service that checks email addresses before we send to them and receives our email provider's bounce reports. Sees what is sent through the contact form, the addresses being checked, and the addresses that bounced.

Cloudflare

Cloudflare · global

The bot check on the contact form. Sees the visitor's address and what their browser tells the check, and nothing from inside any account.

Purelymail

Purelymail · United States

The mailbox behind hi@determesh.com. Sees what people write to us.

GitHub

GitHub · United States

Holds the source code and runs the website's deployments. Sees no personal data: nothing of yours is in a repository.

Deliberately not on the list

Finding the right passage in a company's documents needs their text turned into vectors. That runs on our own servers, with a model we run ourselves, so the documents are not sent anywhere for it.

The systems a company connects, its APIs, databases and mailbox, are the company's own choice and its own suppliers, not ours.

Adding one

Before a new company starts handling a company's data, this page changes and we write to every company it affects. You are told rather than expected to notice.

If you object to one, tell us. We cannot run Determesh without an AI model provider and a mail provider, so an objection to one doing that job is a reason for a conversation, and possibly for you to leave, not something we will pretend to work around.
