The contracting party is Marcel Kuhla, trading as kuhla.tech, Johannesstr. 21
56112 Lahnstein
Rheinland-Pfalz
Deutschland. The offer is exclusively for businesses within the meaning of section 14 BGB.
1. Scope and business customers
This offer is exclusively for businesses under section 14 BGB. Individual agreements take precedence. Customers buy their licences in the Caelia customer area at ca.caelia.tech. They do not enter into paid contracts on this homepage.
2. Contract formation for the base licence and add-ons
To purchase, the customer first registers an account in the Caelia customer area and has the intended licence instance verified. Verification alone does not create a licence agreement. The customer then orders the base licence and one-time add-ons in the customer area. Stripe processes the payment. Each relevant contract is formed when Stripe payment is successful. Update subscriptions are agreed separately under section 4. The order confirmation is provided in the customer area. Any invoice issued by Stripe is imported into the customer area automatically, if available. The product, price and payment details shown during the order process govern. Screenshots and examples on this website are illustrative only.
3. On-premises licence
The base licence costs a one-time net fee of €749 plus applicable VAT per registered and verified Caelia instance. The customer may permanently use the latest version released during the first update year. It must run on the customer's own verified infrastructure. Test instances may be created. An installation without an active base licence is limited to one customer, one private individual or one department, one device and one support ticket. Use beyond these limits requires an active base licence for each instance. The customer installs and operates the software. System requirements are shown in the customer area before purchase. The customer is responsible for its infrastructure, security and regular backups.
4. Update subscription and support
The base licence price includes one year of updates from the licence purchase date. New features, security updates and bug fixes released during this period may be used with the licence. Without renewal, the customer may continue using the latest version released during its paid update period permanently, but receives no new features, security updates or bug fixes afterwards.
Further updates cost €349 net plus applicable VAT per licence and update year and are ordered as a separate update subscription in the customer area. The update subscription contract is formed once Stripe has successfully completed the checkout process and set up the subscription. This also applies if no amount is collected at setup because an already paid update period is still running. The next update period and annual billing start after the end of the already paid update period. The update subscription then renews for a further year at a time unless the customer cancels it beforehand.
If a payment fails, Stripe will make up to three further collection attempts. If all three attempts fail, the renewal order is cancelled; the following update period is not activated and updates for that period are not provided. Any update period already paid for and the permanent right to use the latest version released during it remain unaffected.
Cancellation is possible at any time in the customer area, effective at the end of the current update year.
Support is included in the base licence price. kuhla.tech responds to support requests within 24 hours on working days. Support hours are Monday to Friday, 08:00 to 20:00. For requests received outside these hours, the response period starts at the next support window.
5. Optional add-ons and installation
The branding add-on is a one-time fee of €149 net, the telematics add-on a one-time fee of €249 net and the websites add-on a one-time fee of €49 net, each per base licence or instance. Add-ons extend the relevant base licence. The licence price does not include individual installation services. Customers can request these through the contact form. Scope and price are agreed individually before commissioning. The customer provides necessary access and cooperation.
6. Payment
Payment is made through Stripe in the Caelia customer area. The customer area shows the payment methods and conditions for each order before purchase. Prices on this website are net plus applicable VAT. A further update year is charged only if expressly ordered or if it becomes due under automatic renewal selected by the customer.
7. Cooperation and data protection
Customers supply necessary information and use the software lawfully. For on-premises installations, customers operate and secure their infrastructure unless agreed otherwise. Where kuhla.tech processes personal data on behalf of a customer, the parties enter the required Article 28 GDPR agreement. Personal and confidential data may only be processed within the agreed and legally permitted scope.
8. Defects and liability
Statutory remedies and liability apply unless a valid separate agreement provides otherwise. No blanket exclusion of liability applies. Liability for intent, gross negligence, injury to life, body or health and mandatory statutory liability is not excluded.
9. Final provisions
German law applies subject to mandatory legal requirements. Individual agreements take precedence. Invalidity of an individual provision does not automatically invalidate the remaining agreement; statutory provisions replace invalid terms.
