Who this covers

Hermes is a private tool used only by its owner, Jonathon Wong. It has no other users.

What Hermes accesses

With the owner's permission, Hermes uses the Google Calendar API scope calendar.events to create, update and delete rota shift events in the owner's own Google Calendar. It only changes events it created itself.

Hermes also reads the owner's shift feeds from the rota systems he works on.

How data is stored

Shift details and the Google authorisation token are kept on the owner's own computer. Nothing is stored on this website.

Sharing

Hermes does not sell, share or transfer Google user data to anyone. It does not use Google user data for advertising, and does not use it to train AI or machine-learning models.

Hermes's use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.

Revoking access

Access can be withdrawn at any time at myaccount.google.com/permissions.
