How Tethr uses your Google account

Connecting Google Docs is optional. If you connect it, Tethr asks for permission to create and edit Google Docs, and to access only the Drive files that Tethr creates or that you open with it. Tethr uses this access to create your ledger document and write your logged tasks and summaries into it. It does not read your other documents, does not sell your data, and does not use your Google data to train AI models. You can disconnect at any time from Settings.
