What cookies are
Cookies are small text files placed on your device when you visit a website. Similar technologies, such as local storage and session storage in your browser, work in the same way, and this policy covers them too.
Our approach
JustDisplay uses no advertising cookies and does not track you across other websites. The ads that play on displays are chosen from bookings and campaigns, never from your browsing. Only what is strictly necessary is stored without your consent. Anything optional would be set only after you accept it.
What this website stores
| Name | Type | Purpose | Duration |
|---|---|---|---|
| jsIntro | Session storage (essential) | Remembers that the opening animation has already been shown, so it is not repeated on every page | Until you close the tab |
| jsLang | Local storage (functional) | Remembers the language you chose, so the suggestion to switch language is not shown again. Set only when you pick a language or close the suggestion | Until you clear your browser data |
| jsCountry | Local storage (functional) | Remembers the country you chose in the footer, so prices are shown in its currency | Until you clear your browser data |
| js_theme | Cookie (functional) | Remembers the theme you chose (dark, light or the device setting) with the theme button beside the language. Shared by justdisplay.app and the dashboard | 1 year |
On the login page
| Name | Type | Purpose | Duration |
|---|---|---|---|
| js_auth_b | Cookie (essential, not readable by scripts) | Ties a sign-in to the browser where it was made, so a sign-in link cannot be used on another device | A few minutes |
| js_g_state | Cookie (essential, not readable by scripts) | Set only when you click “Continue with Google”: checks that the answer coming back from Google belongs to your request | 10 minutes |
| js_pk_here | Cookie (essential) | Remembers that this browser holds a passkey for an address, so the login page asks for the passkey directly. The address is never stored, only a one-way code (SHA-256) of it. Shared by justdisplay.app, justdisplay.app and the dashboard | 400 days, or until the last passkey is removed |
| jsPasskeyHere | Local storage (essential) | The same mark as js_pk_here, kept by the login page | Until you clear your browser data, or a passkey is refused |
| jsPasskeyNo | Local storage (functional) | Remembers that you answered “No, thanks” to the passkey question (one-way code of the address), so it is not asked again | 30 days |
No analytics or advertising cookie is used on this website today. If we add audience measurement later, it will appear in this table and a banner will ask for your consent first. Analytics cookies left by an earlier version of the website (_ga, _ga_…, _gid) are deleted automatically when you visit.
What the dashboard stores
| Type | Purpose | Duration |
|---|---|---|
| Cookie (essential) | Keeps you signed in to your JustDisplay account and remembers a completed two-step sign-in (PHPSESSID) | Session |
| Cookie (essential) | Protects forms and payments against cross-site request forgery | Session |
| Local storage (functional) | Remembers interface choices such as language, help mode, your Marketplace Orders view (tab, period, filters) and a “Not now” to the passkey suggestion (14 days) | Until you clear your browser data |
When you check out in the Marketplace or top up your balance, Stripe’s payment page may set its own cookies, needed for the payment and for fraud prevention, under its own policy.
Player apps
The player apps use no cookies for tracking. They store on the device only what they need to work: the pairing token, downloaded media, schedules and ads for offline playback, and plays waiting to be reported. Unpairing or uninstalling the app removes them.
Third-party content
Fonts, scripts, styles, images and videos on this website are hosted on our own servers, so browsing it sets no third-party cookie. Links to app stores, and map links on Marketplace listings, open that service’s own website, which is governed by its own policy.
Sign in with Google. Nothing from Google is loaded on our pages. Only when you click “Continue with Google” do you go to Google’s own page (accounts.google.com), where Google’s cookies and privacy policy apply; Google then sends you back to JustDisplay with a one-time code, and we use only your name and e-mail address.
Managing your choices
Because JustDisplay only uses essential and functional storage, there is no cookie banner today. If we add optional cookies, a banner and a “Cookie settings” link in the footer will let you accept, refuse and change your mind at any time.
- Your browser lets you block or delete cookies and clear local storage.
- Blocking essential cookies prevents you from signing in to the dashboard and paying for bookings.
Changes to this policy
We update this page whenever the cookies or storage we use change. The date at the top of the page shows the last update.
