This page describes the Productivity app for Google Chat (“the Chat app”), which sends a Member’s Productivity notifications to them in a Google Chat direct message. Productivity is the work tracker of Educa. The Chat app is optional: nothing is sent to Google Chat until a Member connects it.

What the Chat app receives

When you add the Chat app or message it, Google tells it:

• your Google Chat user ID,
• your display name in Google Chat, and
• the direct message space the app shares with you.

Productivity reads only your Google Chat user ID and display name from what Google sends, and keeps no email address or picture. The app also receives the text of a message you send it, only to answer it; the text is not stored.

What the Chat app sends

All messages go to your direct message with the app:

• a welcome message with a Kết nối tài khoản (Connect your account) button, and the same button again if you message the app before connecting,
• a confirmation when you connect, and a test notification if you ask for one,
• a line saying notifications stopped, when you disconnect,
• copies of your Productivity notifications, for the kinds you switched on in Settings › Notifications (for example a task assigned to you, an @mention, or your overdue tasks each morning). A copy says what the notification in your Productivity Inbox says: who did what, the task’s name and a short excerpt of a comment, with a link that opens it in Productivity.

The app never acts as you, never reads other conversations, and works only in direct messages. In a group space it replies that it works only in direct messages and does nothing else.

Where it is kept

• Your Google Chat user ID and direct message space are kept in a private table of Productivity’s database (PostgreSQL on Supabase). Only Productivity’s server reads that table; the Productivity app on your screen cannot.
• Your display name, whether the connection is working, and the time you connected are kept in a table that only you can read in Productivity.
• The Kết nối tài khoản button carries a one-time token that is valid for 30 minutes and once. Productivity stores only its hash, together with your Google Chat user ID, direct message space and display name, so that the button can link you. This also applies if you add the app but never connect. The token’s record is removed once it has been used or has expired, the next time a button is made.
• The Chat app signs in to Google with a service account. Its key is a server secret and is never shown to anyone.

Productivity does not sell this data, share it with advertisers, or use it for anything except sending your notifications.

How to disconnect and remove the app

• In Productivity, open Settings › Notifications, find the Google Chat notifications card and press Disconnect. Productivity deletes your link at once. Its last message says notifications stopped and carries a new Kết nối tài khoản button, so you can connect again. Your Google Chat user ID, direct message space and display name stay with that button until the next button is made or you remove the app from the conversation.
• To remove the app from Google Chat, open your direct message with Productivity in Google Chat and remove the app from the conversation. Productivity then deletes your link too, if it is still there.
