Tarsen stores the work you put into it and as little else as we can manage. This page describes what is collected, why, and how to get it back or delete it.

What we store

Your account details come from your sign-in provider: name, email address and profile picture. We keep a local copy so boards can show who did what without calling out to a third party on every request.

Everything you create (projects, lists, cards, descriptions, comments, checklists, attachments and activity history) is stored so the product can work. It belongs to your workspace and is only readable by members of that workspace with access to the relevant project.

What we do not do

We do not sell your data, and we do not use the contents of your cards or comments to train models.

Product analytics records which features are used: that a search happened, that a card was moved. Never what you searched for or what the card said.

AI features

If your workspace has AI enabled and an API key is configured, the content of the projects you can access may be sent to the configured provider (OpenAI or Anthropic) to answer your question. Only data you are already authorised to read is included, and never data from another workspace.

AI can be switched off for a whole workspace in settings. With it off, Mission Mode still works, because its ranking is deterministic and runs locally.

Sub-processors

Tarsen relies on: Clerk (authentication), Convex (database, file storage and server functions), Vercel (hosting), Stripe (payments), Resend (transactional email), PostHog (product analytics), Sentry (error monitoring), and your configured AI provider. Each processes only what its function requires.

Getting your data out, and deleting it

You can export a project or an entire workspace as JSON, and your cards as CSV, at any time from workspace settings.

Deleting your account removes your profile and revokes your access everywhere. Content you authored inside a shared workspace is not deleted along with it, because doing so would silently destroy other people's boards; workspace owners can remove that content themselves.
