What Thursday Does

Thursday is a browser extension that connects your Chrome browser to an AI agent running on our server. When you click a Thursday link, the agent automates web tasks (clicking, typing, navigating) in your browser on your behalf.

Data We Collect

• Anonymous user ID: A randomly generated UUID stored locally in your browser. Used to recall previously provided information (via Supermemory) so you don't have to re-enter it. This ID is not linked to your identity.
• Information you voluntarily provide: When the agent asks you for input (e.g. email, password, name), your responses are sent to our server to complete the task. If Supermemory is enabled, these are saved so you won't be asked again.
• Page content: The agent reads the content of web pages you direct it to in order to navigate and complete tasks. This data is processed in real-time and not stored.
• Debug logs: The extension stores up to 500 log entries locally in your browser for troubleshooting. These are not sent to our servers unless you are actively running a workflow.

Data We Do NOT Collect

• We do not track your browsing history
• We do not collect data when the extension is idle
• We do not serve ads or sell any data to third parties
• We do not collect financial or health information

How Data Is Used

All data collected is used solely to complete the web task you requested. Personal information you provide through the ask-human overlay is forwarded to the AI agent to fill in forms on your behalf. If Supermemory is enabled, it is stored encrypted so the agent can suggest it in future sessions.

Data Storage

Workflow data (task descriptions and step logs) is stored on our server for up to 24 hours, then automatically deleted. Your anonymous user ID and debug logs are stored locally in your browser and can be cleared at any time through the extension's popup.

Third-Party Services

Thursday uses Supermemory (supermemory.ai) to optionally store and recall user-provided information. No data is shared with any other third parties.

Your Rights

You can clear all locally stored data by removing the extension. You can request deletion of any Supermemory data by contacting us.
