Our
subprocessors
The companies that help us run Martia and process personal data along the way — what each one does, which data it receives, and where.
About this list
Martia Labs sp. z o.o. is the controller of your personal data. To run Martia we rely on the providers below, and each one receives only the data its job requires.
This page is part of our Privacy Policy, which explains what data we process, why, and on what legal basis. We keep the list of providers here so that it is always current.
Processors handle data only on our instructions. Independent controllers decide for themselves how they process data, under their own privacy policies, so they are listed separately.

Services you connect yourself
If you connect Martia to an AI assistant such as ChatGPT or Claude, that assistant's provider processes what it reads from Martia under its own terms and at your request. It is not our subprocessor — you decide whether to connect it.
Transfers outside the EEA
Some providers process data outside the European Economic Area; the location of each one is shown above. For those transfers we rely on the mechanisms provided for by law: standard contractual clauses or an adequacy decision (including the EU–US Data Privacy Framework, where applicable).
Changes to this list
We update this page before a new provider starts processing personal data, and the date on this page changes with every update. Questions about our providers: support@martia.ai.
