Syrebrum

What Syrebrum connects to, and how much it's allowed to touch.

Every connection asks for the least access it needs, read-only by default, using each provider's own sign-in. Tokens are stored on your computer, readable only by you. Disconnect anything in the app at any time and its stored token is deleted.

Questions about connections

How do I disconnect a service?

Disconnect it in the app at any time, which deletes its stored token from your computer. You can also revoke Syrebrum's access in that provider's own account settings.

Where are my sign-in tokens stored?

On your computer, readable only by you. Sy never handles your passwords, keys or tokens.

Is my data sold or used to train AI?

No. Data from connected services is used only to provide the features you see, for your own business, on your own computer. It isn't sold, shared with third parties, used for advertising, or used to train AI models.

Why are the business integrations in beta?

They work, but they need setup and are still being proven. We'd rather say so plainly.

Tell Sy what you want done.

YouCheck every machine and tell me what needs fixing first.
