What Teather can access in your Google account

• Your email address and Google account id, so we know which Drive to use and can show you who is signed in.
• Your name and the address of your Google profile photo, so connected sites can show who is signed in. To change them, change them in your Google account.
• Only the files Teather creates in your Google Drive (Google's drive.file permission). Teather can't see, read or change any other file in your Drive.

Where your data is kept

The data sites save through Teather, such as settings, notes and drafts, is stored only in your Google Drive, in a folder named Teather. Teather's servers pass it between the site and your Drive, but do not keep a copy.

What Teather's servers keep

• Your email address, Google account id, name and profile photo address. The photo address is checked against Google about once a day.
• The Google tokens that let Teather reach your Teather folder while you are away, encrypted.
• For each site you are signed in to: which site it is and when the sign-in ends. Sign-ins end after 60 days without use.
• The ids of your Teather folder and its files, so they can be found quickly.

We don't sell or share any of this, and we don't use it for advertising.

What sites see

Each site can only read and change the data in its own folder. Sites can also see your email address, Google account id, name and profile photo, so they can show who is signed in. A site's server can be told who you are with a signed note from Teather, so that signing in to Teather can also sign you in to that site. Sites never receive your Google tokens or access to the rest of your Google account.

Some sites can ask to let their server read and write their folder while you are away (for example, so a course's grades reach its instructor's folder when students submit work). Teather asks you first on its own page, and only records your permission after you sign in with Google. You can take it back at any time on your data page, and deleting a site's folder or signing out everywhere takes it back too.

Removing your data

• On your data page, Delete & disconnect removes one site's folder (to your Drive trash) and signs you out of that site everywhere.
• Sign out everywhere on the same page removes Teather's access to your Drive and deletes your sign-ins and tokens from our servers.
• You can also remove Teather in your Google Account under Security, "Your connections to third-party apps & services".
• Your Teather folder stays in your Drive until you delete it.

Use of Google data

Teather's use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.
