What this notice covers

This privacy policy covers the SigmaOS application only and the way we collect, process, and store data as part of the service.

Data collection

Why we collect data

We collect data in order to improve the SigmaOS application, to keep you up to date with the development of SigmaOS, and to send you an invitation to sign up to the service when it's ready.

The data we collect

We collect your name, email address, and the engagement you have with the product. This includes information about when you create workspaces, open pages, and view modals.

We do not track any identifying information linked to your web-activity (history, cookies, url of websites visited, workspace names, etc…) without your explicit consent. All of this information is stored locally on your computer.

Cloud syncing

You can decide to activate cloud syncing of your SigmaOS session so your activity is identical accross different devices. Cloud syncing is deactivated by default.

If you choose to activate cloud syncing, your web-activity data (history, cookies, url of websites visited, workspace names, etc.) will be stored safely and encrypted in SigmaOS’ servers.

This data is only used for the purposes of cloud syncing: restoring your session.

These servers are powered by AWS (Amazon Web Services).
