Cookie Policy
Every cookie and stored value we set, and what each one is for.
Last updated 19 July 2026
The complete list
This is everything we store in your browser. Most of it is needed to run the service; one entry, noted below, is not.
| Name | Kind | What it is for | How long |
|---|---|---|---|
| __session | Cookie | Keeps you signed in. Set by our authentication provider. | Session |
| dfly_panel_session | Cookie | Keeps an administrator signed in to the staff panel. | Session |
| dfly_campaign | Cookie | Remembers which campaign link brought you here, so we can tell which of our own links work. It holds a campaign code and nothing about you. | 30 days |
| dfly-cookie-preference | Local storage | Remembers that you have seen the cookie notice. | Until cleared |
| dfly.sidebar.collapsed | Local storage | Remembers whether you collapsed the dashboard sidebar. | Until cleared |
| dfly.checkout.reference | Session storage | Holds the reference of a payment in progress so we can show you its result. | Until the tab closes |
What we do not set
No advertising cookies, no third-party trackers, no analytics that follow you across other websites. We do not sell or share any of this, and none of it is used to build a profile of you.
The one that is not strictly necessary
dfly_campaign exists so we can tell which of our own adverts and links people arrive from. It is our own cookie, it is not shared with anyone, and it cannot follow you to other websites — but it serves us rather than you, so we say so rather than filing it under “necessary”.
You can delete it at any time in your browser settings, and the service works exactly the same without it.
Managing them
Every browser lets you view and delete cookies and stored data for a site. Removing the session cookie signs you out; removing the rest costs you nothing but a preference.
