# Where Groupthink's Memory Comes From > Every way Groupthink learns about the people in your life, what each one reads, and whether it is on. Source: https://groupthink.com/docs/memory_sources/ Last updated: 2026-10-02 Groupthink remembers the people in your life from a set of sources. Some run on their own once you connect them. Some only run when you hand Groupthink something. A few are off until you turn them on. This page lists all of them in one place, with a link to each source's own page for the details. Everything Groupthink keeps about a person is private to you, and each fact names where it came from. ## How to read the tables - **Starts** says whether a source runs on its own once it is connected, or only when you do something. - **Counts as** says which date on the person it moves. Groupthink keeps two: **Last meeting** (a live conversation, in person, on a call, or on video) and **Last contact** (anything asynchronous, such as a text or an email). Both appear as columns in your [people list](/docs/relationships), and either one keeps someone off the Going Cold list. "Nothing" means the source adds to what you know about the person without moving either date. ## Sources that run on their own | Source | What it reads | Starts | Counts as | | ------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------- | -------------------------------------- | | [Google Calendar](/docs/google_calendar) and [Outlook Calendar](/docs/outlook_calendar) | Your events and who was invited, including past events: 12 months back on Free, up to 3 years on Pro | On once connected | Last meeting | | Personal events without invites ([details](/docs/relationships#personal-events-without-invites)) | A person's name in the title of an event you created with no attendees, such as "Dinner with Ines" | Suggested, you confirm | Last meeting | | The notetaker on [Zoom](/docs/zoom_integration), [Google Meet](/docs/google_meet_integration) and [Microsoft Teams](/docs/microsoft_teams_integration) | What was said in the calls it records, and who said it | Off until you turn on auto-join, or add it to a meeting.

Turning a source off stops new information from coming in. What it already added stays on the person, and you can [export everything](/docs/export_your_data) at any time.
