Subprocessors

Last updated 11 October 2026 · Seidr Stack

Five companies help us run /Seiðr: hosting, database, two AI providers and payments. Your account data and files are stored in Mumbai, India.

01Who processes data for us

These companies process personal data for us, only to run the Service, under written agreements that require them to protect it.

02Services you connect

Services you choose to connect (publishing channels, media tools, Linear, Jira, Slack, and the sources you read your brand from) aren’t our subprocessors: they act for you, under your own account and agreement with them. We send them only what you ask us to.

03Changes

We update this page before adding or replacing a subprocessor. Accounts under our Data Processing Agreement can ask to be told by email at least 14 days before, and object on reasonable data-protection grounds; write to support@seidrstack.com.
