1. Description of the service

LowFat is an open-source, third-party email client that connects to your Google account via OAuth 2.0 and the Gmail API to provide a lightweight interface for reading, composing, and managing email. LowFat is not affiliated with, endorsed by, or sponsored by Google LLC or any of its subsidiaries. "Gmail", "Google", and related marks are trademarks of Google LLC.

2. Open source and hosted version

LowFat is primarily an open-source project. The source code is publicly available and you are free to self-host your own instance under the terms of the applicable open-source license. We also offer a hosted version of the service for convenience. These Terms apply only to the hosted version. Self-hosted instances are governed by their respective operators.
