Who we are and what these terms cover
JustSigns is cloud digital signage software provided as a service, published and operated by IDEALOGY, a SARL with a share capital of €50,000, RCS Paris 505 014 506, VAT number FR45505014506, whose registered office is at 50 avenue des Champs-Élysées, 75008 Paris, France (“IDEALOGY”, “JustSigns”, “we”). IDEALOGY has been designing and running software for businesses since 2008.
These terms cover justsigns.tv, the JustSigns dashboard, the JustSigns Marketplace and the JustSigns player apps. Other services sold by IDEALOGY, such as JustCaster or its managed social media service, have their own contracts and are not covered here.
Our services and key words
JustSigns offers three services, which you can use separately or together:
- Display – show your own content (media, playlists, live channels and schedules) on screens you pair with the player app.
- Public Ad Display – list advertising space you own (a digital screen, a billboard or a TV channel) in the Marketplace and get paid for bookings.
- Marketplace and network campaigns – book time slots or display impressions on other people’s listings, or launch a network campaign (“Launch Ad Campaign”, also called Cloud Premium Ads) across eligible screens of a country.
In these terms: a display is a screen paired with your account; a listing is a Public Ad Display shown in the Marketplace; the owner is the account that publishes a listing; the advertiser is the account that books it; a booking (or order) is a paid purchase of time slots, display impressions, a billboard or TV booking, or a network campaign; a play is one playback of an ad reported by a player; an ad break is the Top, Middle or Last position in a display’s content loop; your balance is the money held in your JustSigns account. More detail on each service is in our How it works guides.
Acceptance
By creating an account, publishing a listing, making a booking or otherwise using JustSigns, you accept these terms. If you use JustSigns for a company, you confirm that you are allowed to accept them on its behalf.
Your account and team
- Give accurate information, including your country, which sets your currency, your payment methods and where your network campaigns run.
- Keep your login details confidential and tell us at contact@justsigns.tv about any unauthorised use. Two-step sign-in is available and recommended.
- You are responsible for what happens in your account, including the actions of the members you invite and the sections you give them access to.
- Each person uses their own login; logins may not be shared.
Plans and the Free plan
The plan you choose sets how many displays, Public Ad Display listings, members, storage and Proof of Play displays you can use, as shown on the pricing page.
The Free plan is free forever: no time limit and no payment card required. In exchange, displays on the Free plan may show JustSigns network ads in the ad breaks of their content loop. Displays on a paid plan never show network ads. You can move to a paid plan at any time.
Prices on the pricing page are shown excluding VAT, in the currency of your country. VAT is added where it applies.
Paid plans: billing, renewal and cancellation
- Monthly plans renew every month and yearly plans every year, until you cancel. Payment is taken when you subscribe and at each renewal.
- You can cancel at any time in Subscription. Access continues until the end of the period already paid, which is not refunded.
- Upgrades apply immediately; downgrades apply at the next renewal. If you go over a lower plan’s limits, you choose which displays and listings stay active.
- Invoices are available in Billing. If a payment fails or an invoice remains unpaid after a reminder, we may suspend paid features. For business customers, late payment interest and the €40 fixed recovery indemnity provided by French law may apply.
Screens, players and internet
You supply the screens, the player devices and the internet connection. JustSigns runs on the platforms listed on our Download page (Android, Fire TV, Windows, Samsung and LG). Content already received keeps playing offline, but new content, changes, ads and play reports need a connection.
A display’s place is used for Marketplace distance search and for network campaigns. It is taken from the device’s location when available, otherwise from the listing’s map point, otherwise from the internet connection, and may therefore be approximate.
Player apps are distributed through third-party app stores or downloaded from justsigns.tv and run on third-party operating systems. Their features and rules can change, and the terms of those stores and systems also apply to you.
How ads play on a display
Your own content always comes first. Whatever a display shows (a playlist, one media, a live stream or a schedule) plays as a loop, and ads only enter three breaks of that loop: Top, Middle and Last. In a break, display impressions bought for that display play first, then, on Free-plan displays only, one network ad. When a display shows a single image or a live stream, a break comes at the interval set in the listing (by default every 60 seconds for an image and every 5 minutes for a live stream).
During a sold time slot, the display plays only the content of the advertiser who booked that slot, with no other ads.
Selling advertising space (Public Ad Display)
When you publish a listing, you confirm that you have the right to sell advertising on that screen, billboard or TV channel, and you agree to:
- describe it accurately: type, place and map point, size, orientation, venue, photos, prices, available dates and slots, impression packs and the advertiser industries you accept;
- keep a digital display switched on, connected and showing its listing schedule during sold slots, and keep it online so that bought impressions can play;
- for billboards and TV channels, accept or decline each request in time, put up the artwork or air the spot as booked, and send proof when the advertiser asks for it;
- refuse only ads that break the law, these terms or the industries you excluded, and not to change prices or availability of what has already been booked;
- comply with the rules that apply to your space (permits, local advertising rules, broadcasting rules) and declare your own income and taxes.
A listing with running or upcoming bookings cannot be deleted or switched off. Activating a digital listing sets its display to the listing’s schedule. After a booking is completed, its value minus the marketplace fees is credited to your balance.
Booking advertising (Marketplace)
- Prices are set by the owner. The total, including the marketplace fees, is shown before you pay. A booking exists only once payment is confirmed; slots you select are held for you only briefly while you check out.
- Time slots give you the display for the booked half hours, with only your content. Display impressions belong to that one listing and play in the break you choose until they are used; they are not tied to a date.
- Nothing plays until you assign media to the booking in Marketplace Orders. Check the display’s orientation and the dates before you assign.
- Ad plays are playback events reported by the players. They are not a measure of how many people saw your ad, and no audience, traffic or sales result is promised.
- The advertising contract for a listing is between you and its owner; JustSigns provides the platform, collects the payment and settles it as described in these terms.
Billboard and TV channel bookings
A billboard or TV booking is a request to the owner. Your payment is held by JustSigns until the booking is completed. It follows these steps: Requested → Accepted → Aired → Proof → Completed.
- The owner accepts or declines the request. A declined request is refunded.
- After the booked period, the advertiser confirms the booking or asks for proof. The owner then sends photos or a video in the order messages, or refunds.
- Each step has a deadline shown in the order. If proof was asked and not sent in time, the booking is refunded automatically. If proof was sent and the advertiser did not answer in time, the booking is completed automatically and the owner is paid.
- Either party can open a dispute; see Problems with a booking.
Network campaigns (Launch Ad Campaign)
- A network campaign buys a number of impressions in the countries you choose, at the position (Top, Middle or Last) and ad length you pay for. It does not reserve any specific display or time.
- Network ads play only on eligible Free-plan displays that are online, match the orientation you chose and, if you set one, the radius around a place. Several campaigns share breaks by taking turns, one ad per break.
- How fast impressions are delivered depends on the number of eligible displays that are online; no delivery date is promised. Impressions remain in your campaign until they are played.
- Nothing plays until you assign media to the campaign in Marketplace Orders → Network campaigns.
Advertising content rules
Every ad shown through JustSigns must be lawful in the country where it is displayed, truthful and not misleading, and you must hold all rights to its texts, images, music, video, brands and people shown. Ads must not promote illegal products or services, contain adult, violent, hateful or discriminatory content, or break the rules that apply to regulated sectors such as alcohol, tobacco and vaping, gambling, medicines, financial products or political advertising.
Owners may restrict the industries they accept. We may refuse, pause or remove an ad, a booking or a listing that breaks these rules or that we are asked to remove by an authority; where the advertiser is at fault, the booking is not refunded.
Proof of Play and order reports
Proof of Play, available on the displays your plan allows, records each display’s online, offline and public-display time and every media played, with its count and duration. Marketplace Orders records every ad play of a booking with its date and time, display, media, city, country and the latitude and longitude where the display ran, and lets you export it as CSV.
These records come from the players. They depend on the device being online and reporting, arrive in batches (the latest plays can take up to about 10 minutes) and may be incomplete if a device is offline for long or tampered with. They are records of playback, not of audience. In case of disagreement, our server records are used as the reference, unless proven wrong.
Balance, fees, refunds and payouts
- Payments are processed by Stripe. You can add money to your balance with the payment methods Stripe offers in your country. Card and payment account details are entered on Stripe and are never stored by JustSigns. Any processing fee is shown before you confirm.
- Bookings and campaigns can be paid with your balance, a payment method or both. Marketplace fees are shown to the advertiser before payment and to the owner in the booking’s earnings.
- Refunds for declined billboard or TV requests, missing proof or a dispute decided in the advertiser’s favour are credited to the advertiser’s JustSigns balance. If a digital display was offline during a sold slot, the advertiser can contact us with the order’s report and we will review it with the owner.
- Owners withdraw their balance through Stripe. Payout details are entered on Stripe and kept by Stripe, not by JustSigns, and Stripe may ask you to verify your identity before a first payout. Any withdrawal fee is shown before you confirm. We may hold a payout while a dispute or a suspected fraud is reviewed.
- Fixed prices and fees can change for the future; a booking already paid keeps its price.
Problems with a booking
Start with the order messages: owners and advertisers can exchange files and explanations there. If you cannot agree, open a dispute from the order (billboard and TV bookings) or write to contact@justsigns.tv with the order number. Our team reviews the order, the play records, the proof and the messages, and decides whether the booking is completed, partly or fully refunded. We aim to answer within 10 business days. This does not limit your right to go to court or, for consumers, to a mediator.
Acceptable use
- No unlawful, infringing, hateful, deceptive or harassing content on your displays or in your listings.
- Content you display must respect the rights of others, including image rights, copyright and licences for showing music or video in public.
- You are responsible for following local rules that apply to screens in public places and to advertising.
- No fake listings, fake bookings or artificial plays, no manipulation of a player or its reports, and no use of Marketplace contacts to take bookings outside JustSigns to avoid fees.
- No attempt to disrupt the service, reverse engineer it, resell it or access other customers’ data.
Your content
You keep all rights to the content you upload and display. You grant IDEALOGY the limited right to host, process and transmit that content only to operate the service for you. When you book advertising, you also grant the owner of the listing the right to display your ad for that booking only. Listing details and photos you publish are shown publicly in the Marketplace. We do not use your content in our own marketing without your written agreement.
Availability and support
We aim to keep JustSigns available at all times but cannot guarantee uninterrupted service. JustSigns runs on a cloud and CDN infrastructure: the website, the dashboard and your content are served from the locations best suited to your country. Planned maintenance is announced in advance whenever possible. Support is available in French and English at contact@justsigns.tv on business days.
Suspension and termination
We may suspend or close an account, a listing or a booking that breaks these terms, remains unpaid, or puts the service, other customers or the public at risk. Except in serious cases, we give notice first. You can close your account at any time once your bookings are completed and your balance is withdrawn, and you can download your content before it is deleted.
Liability
IDEALOGY provides the service with the care expected of a professional. We are not liable for indirect damage such as loss of profit, loss of audience or loss of opportunity, nor for damage caused by a third-party device, operating system, app store, payment provider or internet provider. As a platform, we are not responsible for the listings, ads and conduct of owners and advertisers, nor for the condition, location or audience of an advertising space. For direct damage, our total liability is limited to the amounts you paid to JustSigns during the twelve months before the event. Nothing in these terms limits liability that cannot be limited by law.
Consumers
JustSigns is designed for professionals. If you subscribe as a consumer, you have 14 days to withdraw from a paid plan. By asking for immediate access, you accept that the service starts during that period; if you then withdraw, you pay only for what has been used. Advertising bookings for a specific date or period are not subject to the withdrawal right once confirmed, as the law allows. Consumers may also contact a consumer mediator or use the European online dispute resolution platform.
Governing law and disputes
These terms are governed by French law. Before any legal action, please write to contact@justsigns.tv so that we can look for a solution. Failing agreement, disputes are submitted to the competent courts of Paris, except where mandatory consumer rules provide otherwise.
Changes to these terms
We may change these terms, for example to reflect new features or new legal requirements. Important changes are announced by e-mail or in the dashboard at least 30 days before they apply. If you do not accept them, you may cancel before they take effect. Bookings already paid stay under the terms in force when they were made.
