These govern using the service, for anyone who does: the account holder, the members of their team, and anyone on the free plan. Anything touching payment is governed by the terms of sale.
These terms govern access to and use of Quiet Guard. They apply to anyone using the service, paying or not: the account holder, every member of a team, and any user of a free plan or a trial.
They do not govern the sale of subscriptions, which is governed by the terms of sale. The two documents complement each other.
Creating an account or accepting an invitation to join a team constitutes unreserved acceptance of these terms in the version in force on that date. A dated version is permanently available.
The account holder undertakes that the members it invites will comply with these terms.
The Client is responsible for the accuracy of its account details, for the confidentiality of its credentials and API keys, and for any activity carried out with them.
A compromised key must be revoked by the Client from the interface and reported to the Publisher without delay. Keys are stored hashed and shown in the clear only once: the Publisher cannot retrieve them.
An account belongs to a team. The team owner administers the members, their roles and the billing.
By inviting someone, the Client warrants that it is entitled to give them access to its team's data. Removing a member removes their access immediately, without deleting data they may have seen elsewhere.
The service is provided to monitor the Client's applications. The following uses are prohibited, and the list is not exhaustive.
The Client keeps full ownership of the data its application sends. The Publisher acquires no rights in it.
The Client grants the Publisher the licence strictly needed to host, process and present that data as part of the service, for the term of the contract and for that purpose alone. This licence permits no commercial exploitation, no assignment, and no model training.
The Client warrants that it holds the necessary rights in the data it sends and indemnifies the Publisher against any third-party claim based on its content or its transmission.
The Client may send feedback, suggestions or reports. It grants the Publisher the right to use them freely to improve the service, without consideration and without any obligation to credit.
This covers ideas for improvement only. It extends to no data, no code and no confidential information of the Client.
The service, its interface, its documentation, its brand and its code remain the property of the Publisher or its licensors.
The subscription grants a personal, non-exclusive and non-transferable right of use for the term of the contract. It transfers no rights.
The published client packages are governed by the open source licence stated in their repository, which prevails over this article as regards them.
The Publisher uses reasonable means to keep the service available, without guaranteeing a given rate.
Planned maintenance interruptions are announced where possible and scheduled, as far as practicable, outside business hours.
The service changes. The Publisher may add, alter or remove features; removing a substantial feature from a paid plan is covered by the corresponding article of the terms of sale.
Any vulnerability found in the service can be reported to legal@quietsystems.dev. The Publisher acknowledges receipt, acts on the report, and takes no action against anyone who reported in good faith, without exploiting the flaw beyond what was needed to demonstrate it and without premature disclosure.
This tolerance is not permission to run a penetration test: a test requires prior written agreement.
The Publisher may suspend access without notice where its use endangers the security, integrity or availability of the service for others, or where it is plainly unlawful. The Client is informed without delay and the suspension is lifted as soon as the cause is gone.
Outside an emergency, suspension for breach follows a formal notice left unanswered for eight days.
The Client may close its account at any time, from its team settings. The request is confirmed by typing the team identifier, and a written confirmation is emailed to the owner.
Closure takes effect at the end of the period already committed to, and never sooner than seven days. It can be called off from the same page until that date. After it, the team, its projects, its exceptions, its logs, its encrypted backups and its logo are deleted, with no way back, on the terms set out in the data processing agreement.
Deleting the account of a person is requested from that person's own account settings. It requires them to own no team: a team is the party to the contract and is closed first.
Some features may be offered for trial and are marked as such. They are provided as is, may be changed or withdrawn at any time, and carry no availability commitment and no compensation.
A Client who turns them on does so knowingly and does not make a critical use depend on them.
The service is provided as is and as available. The Publisher does not warrant that it will meet a particular need, nor that it will run without interruption or error, nor that the results it produces will be exhaustive.
In particular, monitoring an application depends on what that application sends: an error never sent cannot be detected. These exclusions apply within the limits the law allows.
The limitations and exclusions of liability set out in the terms of sale apply to these terms.
The Client alone is responsible for the use it makes of the service, for the data it sends to it, and for the decisions it takes on the strength of what it shows.
The processing of personal data is described in the privacy policy and governed, for the data the Client's application sends, by the data processing agreement.
Where these terms and that agreement conflict on a data protection point, the agreement prevails.
The Publisher cites the Client's name or brand as a reference only with its prior written consent, revocable at any time.
No reference is published by default, and refusing has no effect on the service.
The Publisher may amend these terms. Any substantial change is notified to team owners at least thirty days before it takes effect.
Continuing to use the service beyond that date constitutes acceptance.
These terms are governed by French law. The jurisdiction clause in the terms of sale applies to them.
