Terms
Limitations of our Obligations, and Support
At this point in time we are committed to offering tools at no cost to every user, however we assume no legal responsibility for its misuse by end users, nor do we make any guarantees of its quality or reliability. Because we store no data outside of the end-user’s Google account, the potential failure of this tool generally poses no privacy risk, but we cannot offer a 100% guarantee of this.
While we make every effort to ensure their functionality, add-ons exist within a fast-moving product ecosystem in which things break and may need to be fixed from time to time.
As a reminder, here are Google own terms of service for End Users Using Add-ons
