Terms of Service

Last updated: 30 July 2026. These terms are governed by French law.

These terms govern the UptimeEZ hosted plan, operated by Cœur du Web (SASU, 58 rue de Monceau, 75008 Paris, France, RCS Paris 850 520 941), referred to below as “we”. They do not govern the self-hosted engine, which is published under the MIT licence and carries its own terms in its repository.

1. A business-only service

The hosted plan is offered exclusively to professionals acting for purposes relating to their trade, business, craft or profession. By subscribing you confirm that you are such a professional, and you provide your company name or registration number when you sign up. Because this is a business-to-business contract, the fourteen-day withdrawal right and the consumer mediation scheme of French consumer law do not apply. If you are a consumer, do not subscribe: install the free engine instead, which costs nothing and holds nothing back.

2. What the service does

We run one instance of the UptimeEZ engine for you, on a dedicated server in France, with a database of its own. It checks the addresses you configure, records the measurements, and notifies you through the channels you set up. Monitors are not counted or capped.

What we do not promise. We do not guarantee that every incident will be detected, nor that no false alarm will ever be raised. Monitoring observes a site from the outside at intervals you choose; between two checks, we see nothing. Anyone promising otherwise is selling something they cannot deliver.

3. Price, billing and price protection

The subscription is billed monthly in advance, in euros, excluding any applicable tax. Payment is processed by Stripe; we never hold your card details.

The launch price is locked for as long as you keep the plan. If the price rises for new subscribers, yours does not. If we ever had to change the price of an existing subscription, we would tell you at least thirty days in advance and you could cancel before it applied.

The current amount, the tax treatment and what each element covers are set out on the pricing page. Where that page and these terms differ, these terms are the ones that bind us both.

4. Cancelling, and what happens to your data

You cancel from your account, in one click, at any time. The service runs until the end of the period already paid for; we do not refund a partial month.

Cancelling suspends your instance. It does not delete it. Checks and alerts stop, your history stays on disk, and everything resumes where it left off if you come back. The same applies to a failed payment: a billing problem must not cost you the one thing that cannot be rebuilt afterwards.

Your incident history is exportable at any time, by you, without asking us. The Incidents screen of your own instance has an Export CSV button next to the period selector: it hands you one row per incident, with its cause, its duration and the alerts that were sent, for the period you chose, up to one year back and up to five thousand incidents per file. It keeps working after a suspension, which is when it matters most: the instance stays served and your history stays on disk. One detail worth knowing rather than discovering: once a subscription is suspended you sign in to the instance directly, with its own password, because the one-click button in your account is reserved for active subscriptions. If you no longer have that password, write to us and we will get you back in. You can also ask us to delete your instance permanently, which we do on request; how that works, and the one-month deadline we hold ourselves to, are in our privacy policy.

5. What we ask of you

Monitor addresses you own or are authorised to monitor. The service fetches the URLs you give it, which means it can be turned into a scanner or a relay if misused: do not point it at third parties without their agreement, at internal ranges you have no right to probe, or at anything intended to overload a server. Internal and private address ranges are refused by the engine itself, so that one is not left to trust.

How we would find out, since you are entitled to know. We do not inspect what you monitor, and we do not analyse your targets: your list of addresses is yours. What reaches us is a report, typically from the site being hit or from its host, because the requests leave from our IP address and the complaint therefore arrives at our door. On a credible report we may suspend an instance immediately, and we will tell you why and give you the chance to answer. We would rather say this plainly than imply a surveillance of your account that does not exist.

6. Availability and interruptions

We aim to keep the service running continuously and we do not offer a contractual availability commitment. A monitoring tool that claims perfect availability for itself is making the mistake it exists to catch.

Maintenance that requires an interruption is announced in advance when we can foresee it, and here is where: a dated notice in your account, shown to subscribers, from the moment we schedule the work until it is done. For anything longer than a few minutes you also get an email, at the address on your account. Unforeseen work, the kind that follows an incident, is announced as soon as we know ourselves, which is sometimes while it is happening.

7. Liability

We are liable for damage caused by our own failure to perform, up to the amount paid over the twelve months preceding the event. We are not liable for indirect loss, in particular loss of revenue or of custom resulting from an incident on your own sites, whether we detected it or not. Nothing here limits liability that French law does not allow to be limited, including for gross negligence or wilful misconduct.

8. Personal data

We process personal data as described in our privacy policy. Where you configure the service to send alerts to people in your organisation or to your own clients, you decide what is sent and to whom, and you remain responsible for having a lawful basis to do so.

9. Changes to these terms

We may change these terms. A change that affects your rights or the price is announced at least thirty days in advance, and continuing to use the service after that date means you accept it. Cancelling before it applies is always possible.

10. Governing law and jurisdiction

These terms are governed by French law. Any dispute that cannot be settled amicably falls under the jurisdiction of the courts of Paris, France. This clause applies between professionals and does not deprive anyone of a mandatory protection they would be entitled to elsewhere.
