General terms of use and sale

Version of 02/11/2026

This is a translation. If the versions differ, the French text prevails: version française.

These terms govern the use of the KYNA software by professionals.

Article 1 — Parties

KYNA is published by [PUBLISHER: name, legal form, company number and registered office to be completed], reachable at [email protected] (“the Publisher”). The “Customer” is the self-employed person or business using the service for its professional activity. The service is not intended for consumers.

Article 2 — Service

KYNA is online management software: clients, jobs, quotes, change orders, invoices, photos and backups. It runs in the browser, on computer and phone, including offline; data syncs when the connection returns. The Publisher may develop the features; it notifies the Customer at least 30 days before removing an essential feature.

Article 3 — Account

The Customer provides accurate information and keeps its login details secret. It is responsible for actions taken with its accounts and those of its staff. It notifies the Publisher without delay of any unauthorised use.

Article 4 — Customer's responsibility for its documents

KYNA calculates amounts and suggests legal wording, but the Customer remains solely responsible for the content of its quotes and invoices: prices, VAT rates applied, wording, compliance with its tax and accounting obligations, and keeping its records. The Customer is encouraged to have its templates checked by its accountant. Since 1 January 2026, invoices to Belgian VAT-registered businesses must be sent through the Peppol network. KYNA produces the electronic file in Peppol BIS 3.0 format; as long as direct Peppol sending is not included in its plan, the Customer sends this file through the Peppol access point of its choice or through its accountant, and remains responsible for that transmission.

Article 5 — Price and payment

During the test phase, the service is free. After that, the “Essential” plan (the software) is offered; the “Pro” plan (the software and the automated telephone answering service, with a number of minutes included per month; additional minutes charged at the displayed rate) will follow once it is available. Launch price: a Customer who subscribes to “Essential” among the first 50 paying customers, or by 30 June 2027 at the latest, keeps the launch price of €19 excl. VAT per month (or its quarterly or yearly equivalent) for as long as the subscription is not cancelled; the price increase clause below does not apply to that price. Prices are those shown on the website on the day of subscription, excluding VAT, payable in advance monthly, quarterly or yearly, at the Customer's choice (quarterly and yearly payment carry a discount shown on the website). A 30-day free trial ends without cost or commitment if the Customer does not subscribe. A price increase is announced at least 60 days in advance; the Customer may then cancel before it applies. If payment is not made 15 days after a reminder, access may be limited to viewing and exporting data.

Article 6 — Term and termination

The subscription renews automatically for the same period. Either party may end it at any time, effective at the end of the paid period, at no cost. The Publisher may terminate immediately in the event of unlawful use or serious breach, after formal notice that remains without effect for 8 days.

Article 7 — Customer data

The data entered (clients, documents, photos) belongs to the Customer. It may export it at any time, at no cost. After the contract ends, it remains available for export for 60 days, then is deleted from the servers within the following 30 days, unless a legal obligation requires otherwise. The processing of personal data is governed by the data processing agreement, which forms part of these terms.

Article 8 — Availability and backups

The Publisher makes its best efforts to keep the service available at all times (obligation of means), except for announced maintenance and hosting provider outages. During the test phase, the Customer turns on the automatic backup to its own computer, as recommended in the app.

Article 9 — Publisher's liability

The Publisher is liable for its proven faults. It is not liable for indirect damage (loss of turnover or customers, tax penalties linked to the content of a document). Its total liability is limited to the amounts paid by the Customer in the 12 months before the event causing the damage. These limits do not apply in the event of fraud, intentional misconduct or gross negligence.

Article 10 — Intellectual property

The software, the KYNA brand and the website remain the property of the Publisher. The Customer receives a personal, non-exclusive and non-transferable right of use for the duration of the subscription.

Article 11 — Automated assistance

The assistance features (dictation, sentence understanding, suggested tasks, quotes and translations) produce suggestions that the Customer checks before anything is sent. Amount and VAT calculations are never left to them. Sentence understanding and translation take place on the device. Dictation uses the browser's speech recognition: depending on the browser (for example Chrome), the audio may be processed by the browser maker's servers, under its own terms; a Customer who does not want this can type instead. The Customer's data is not used to train models.

Article 12 — Electronic signature

A signature on screen or by link is a simple electronic signature: the signer's name, the date, the time and the document fingerprint (hash) are recorded. Between professionals, it counts as written agreement; for a consumer, it is evidence assessed by the court. For a large amount or a likely dispute, the Customer may also ask for a signature on paper or with the electronic identity card.

Article 13 — Automated telephone answering service (Pro plan)

When this feature is turned on, a Belgian number answers the calls the Customer does not take: a message announces that the call is handled by an automated assistant and may be recorded, then the request is transcribed and summarised for the Customer. The Customer chooses whether to enable recording, informs its callers (the greeting does this) and decides how long recordings are kept (30 days by default). The summary remains a suggestion to be checked.

Article 14 — Changes to the terms

The Publisher may change these terms by notifying the Customer at least 30 days in advance; the new version is presented in the app for acceptance. A Customer who refuses may cancel at no cost before it takes effect.

Article 15 — Governing law and disputes

Belgian law applies. The parties first seek an amicable solution. Failing that, the courts of the judicial district of the Publisher's registered office have jurisdiction.
