Cookie policy
The necessary ones, always. The rest, only if you say yes.
Version 1 · September 25, 2026
A cookie is a small file the site stores in your browser. Efémeris uses some necessary ones, without which the app doesn't work, and, only if you accept, others for analytics and marketing. Until you choose, none of those last two is loaded.
What we store

How to change your choice
From the button below, from Cookie preferences at the bottom of the page, or in Settings. If you withdraw a permission, we delete those cookies and the page reloads. Every six months we ask you again.
You can also block or delete cookies from your browser settings. If you block the necessary ones, you won't be able to sign in.
