Who we are
JustDisplay is a cloud digital signage platform and advertising marketplace published and operated by IDEALOGY, a SARL with a share capital of €50,000, registered with the RCS of Paris under number 505 014 506 (APE code 6201Z, VAT number FR45505014506), whose registered office is at 50 avenue des Champs-Élysées, 75008 Paris, France. IDEALOGY has been designing and running software for businesses since 2008.
For this website, the dashboard, the Marketplace, the player apps and your JustDisplay account, IDEALOGY is the data controller. For the content you display and any personal data it contains about your own customers, staff or visitors, you are the controller and IDEALOGY acts as your processor, under our Data Processing Agreement.

Data we collect
- Account data: name, e-mail address, password (stored hashed), company, country, currency, language, plan, two-step sign-in settings, and the members you invite with the sections they can use.
- Content: images, videos, documents, playlists, live-channel links, schedules and the ads you assign to bookings.
- Display and player data: device name, type and app version, pairing details, IP address, online and offline status, the device’s location when the device provides it, and Proof of Play records (which content played, on which display, when and for how long).
- Marketplace data: your listings (title, description, type, address, map point, size, photos, prices, availability and accepted industries), bookings and campaigns, ad play records with date, time, display, city, country and coordinates, and the messages, artwork and proof files exchanged in an order.
- Payment data: balance top-ups, transactions, payouts, invoices and billing details. Card, bank and payout account details are entered on Stripe, our payment provider, and are never stored by JustDisplay.
- Sign-in data: the passkeys you add (public key and device name only — your fingerprint, face or PIN never leave your device), and your sign-in activity (date, method, IP address and device), kept 180 days so you can check it in Profile → Security.
- Sign in with Google: if you choose “Continue with Google”, Google confirms your name and e-mail address to us. Nothing from Google is loaded on our pages before you click.
- Usage data: pages and features used, device and browser, approximate location derived from your IP address, and technical logs kept for security.
- Messages you send to support, sales or through the contact form.

Display location
A display’s location is used to show listings by distance in the Marketplace, to match network campaigns to the countries and radius chosen by advertisers, and to show advertisers where their ads played. It comes from the device’s location when the device provides it, otherwise from the map point of the listing, otherwise from the IP address. It locates the screen, not the people in front of it. Players do not use cameras or microphones and JustDisplay does not identify viewers.
In the Marketplace, “Near me” uses your browser’s location only if you allow it, only for that search, and it is not stored.
What your screens show in public
Your screens show your content to the people around them, often in public places. JustDisplay players do not use cameras or microphones and do not identify or count viewers. If your content shows people or other personal data (photos, names, testimonials, staff), you are the controller of that data: you must have the right to show it, including people’s consent where required, and IDEALOGY only processes it on your behalf under our Data Processing Agreement.
What other users can see
- Your active listings are public in the Marketplace, including their photos, address and map point. Do not include personal data you do not want to publish.
- For a booking, the owner sees the advertiser’s account name, the ad content and the order messages; the advertiser sees the listing, the play records of their ads, the proof and the order messages.
- Each party may use the other’s data only to carry out that booking.
Player apps and app stores
The JustDisplay player apps are distributed through app stores such as Google Play, the Microsoft Store and the Amazon Appstore, through the Samsung TV platform, or downloaded directly from justdisplay.app. When you download an app from a store, the store processes your data under its own privacy policy.
Once installed, the player app only sends JustDisplay what it needs to pair the display with your account, receive your content, schedules and ads, keep a live connection for instant updates, and report its status, location and plays. You can unpair a display at any time from your dashboard.

Where data is stored and international transfers
JustDisplay runs on a cloud and CDN (content delivery network) infrastructure. Our main hosting is in France, with OVH and IONOS. To deliver content quickly, copies of the website and of your content may also be served by cloud and CDN providers located in or near your country, acting only on our instructions. The full list of hosting providers is in our Legal Notice.
JustDisplay is used in several countries. Stripe, Google and Cloudflare may process data outside the European Economic Area; these transfers rely on the EU–US Data Privacy Framework or the European Commission’s Standard Contractual Clauses, together with any additional safeguards required.
