Annotate element images as comments

Creators and Admins can capture an image of a workbook element, draw on it, and save it with a comment in the element's comments.

Requirements

Image storage and deletion

Sigma stores annotated screenshots in its cloud storage. Sigma encrypts images on the server side with an encryption key that is unique to your organization. Access to the stored images is protected by IAM policy and requires user authentication and permission to the workbook it is from. Sigma also encrypts images during transit via TLS.

By default, images expire after 90 days. Sigma deletes images within 24 hours of expiration. A Sigma organization’s Admin can update the expiration policy to extend it up to 2 years or reduce it down to the 1 day minimum.

To delete all images from an organization, an Admin can set the image time out period to 1 then turn off annotations. All images will be deleted from Sigma storage within 48 hours.

Comments with deleted annotated images show a placeholder where the images used to be. All the text in the comments remain.
