Cookie policy
Last updated 15 November 2026
The cookies and browser storage our sites use, and the third-party content you can choose to load.
In short
- No analytics, advertising or tracking cookies on any of our sites.
- arkemis.space and drones.arkemis.space set no cookies.
- Truss sets only essential sign-in cookies.
- The booking calendar (Cal.com) only loads after you click "Load booking calendar".
arkemis.space and drones.arkemis.space
These sites set no cookies. If you choose to load the booking calendar, we remember that choice in your browser's local storage under the name arkemis:cal-consent, so you are not asked again. It is not sent to us and you can remove it by clearing site data in your browser.
Truss (truss.arkemis.space)
Truss uses these essential cookies to keep you signed in. They are httpOnly and Secure, which means page scripts cannot read them and they are only sent over encrypted connections. Truss does not work without them, so they need no consent.
| Name | Purpose | Lasts |
|---|---|---|
__Host-truss_at | Your signed-in session | 24 hours |
__Host-truss_rt | Keeps you signed in between sessions | 30 days |
__Host-truss_exp | When the current session expires | 24 hours |
The Truss app also keeps your display preferences in your browser's local storage (truss:prefs). It stays on your device. If you choose to load the booking calendar on truss.arkemis.space, that choice is remembered in local storage under arkemis:cal-consent, as on our other sites.
Third-party content: the booking calendar
Our booking calendar is provided by Cal.com. It is not loaded until you click "Load booking calendar". Once loaded, Cal.com may set its own cookies; see Cal.com's cookie and privacy policies. You can always book without loading it by going to cal.com/arkemislabs.
Managing cookies
You can block or delete cookies in your browser settings. If you block the Truss cookies you will not be able to sign in. To reset your calendar choice, clear this site's data in your browser.
