CATS legal
Terms & Conditions
Last updated: August 23, 2026
These terms are provided by Control and Telemetry Systems GmbH (“CTS”), Loretorain 3, 6300 Zug, Switzerland. They contain separate provisions for this website, hardware purchases, and CATS Flights. A section applies only when you use the product or service named in that section.
General terms
These general provisions apply to the CATS website and supplement the product-specific provisions below. If a product-specific provision differs from a general provision, the product-specific provision applies to that product or service.
Product descriptions, documentation, and other website content are provided for general information. They do not replace launch safety procedures, engineering judgment, or compliance with applicable laws and regulations.
Hardware purchases
This section applies to contracts for hardware and other physical products purchased from CTS, including purchases completed through the CATS shop.
Scope and acceptance
These hardware purchase terms apply to the conclusion, content, and execution of contracts for products from CTS. Written or electronic agreements between the parties that state otherwise remain reserved. Notices from CTS in an order confirmation are treated as agreements between the parties unless the customer objects within three working days.
By placing an order, the customer accepts these terms. Amendments, supplements, and subsidiary agreements are effective only if CTS confirms them in writing or electronically. Any general terms and conditions supplied by the customer are rejected.
Products and offers
Product images in advertising, brochures, and the online shop are illustrative and are not binding. Price lists and brochures contain non-binding information and indicative prices. Information supplied by telephone is not binding and does not constitute an offer.
Unless stated otherwise, an offer sent by CTS in writing or by email remains binding for one week after it is issued.
Conclusion of the contract
By selecting the final purchase button, the customer places a binding order for the products in the shopping cart. CTS confirms receipt by email. The purchase contract becomes binding when the customer receives the order confirmation.
Order changes
Customers must send change requests electronically. CTS will explain whether the requested change is possible and under which conditions. Those conditions are accepted if the customer does not reject them within three working days. Electronic confirmation from the customer is always required if the change increases the original order amount by more than 20%.
CTS may make changes to the order confirmation and will communicate them without delay. If CTS increases the price, the customer may withdraw from the contract within ten working days after being notified.
Prices, shipping costs, and payment
The prices shown when the order is placed apply and are final prices. Customs duties are paid by the customer. Payment is made using the methods offered by the online shop and is due in Swiss francs. CTS may restrict the payment methods available for an order. Any transaction fees are paid by the customer. Invoices are issued electronically.
Unless agreed otherwise, payment is due within 30 days of the invoice date. Overdue amounts may accrue interest at 5% per year without a reminder. CTS may withhold deliveries until all due invoices are paid and may withdraw from the contract in the event of payment default. Delivery takes place only after CTS receives payment.
Delivery
The order confirmation and any supplements determine the type and scope of delivery. Delivery is made to the address supplied by the customer. Online shop orders are shipped with Swiss Post, and shipping within Switzerland is free unless the shop states otherwise.
Delivery periods are not binding. CTS will inform the customer of delays. A delayed delivery does not by itself entitle the customer to withdraw from the contract or claim damages. Delivery periods are extended when delay is caused by events outside CTS’s reasonable control. If such an event makes performance impossible, CTS is released from the affected obligation without an obligation to pay damages. CTS may use third parties to fulfil its obligations.
Retention of title
Delivered goods remain the property of CTS until all claims are paid in full. If CTS withdraws because of payment default, the customer must return the purchased item when requested. A product subject to retention of title may be sold only with CTS’s express written consent.
Voluntary withdrawal from an accepted order
Outside the seven-day return policy below, a customer may withdraw from an accepted purchase contract only with written or electronic consent from CTS. In that case, the customer owes CTS a contractual charge of 15% of the order amount, with a minimum charge of CHF 35, for the expenses incurred. CTS may claim additional damages, with the contractual charge credited against that amount.
Seven-day return and refund policy
If you are not satisfied with your purchase, you may request a return within seven days after receiving it. To be eligible, the product must be unused, in the same condition in which it was received, and in its original packaging.
Contact info@catsystems.iowith your order number and reason for the return. CTS will provide return instructions. The customer pays the return shipping costs. After receiving and inspecting the product, CTS will confirm whether the return is approved. Approved refunds are issued to the original payment method.
Transfer of risk and warranty
Benefit and risk pass to the customer when the goods are handed over for shipment. CTS warrants that the products have the agreed characteristics at that time and are free from physical or legal defects that materially impair their value or intended use, subject to any provisions or agreements stating otherwise.
CATS products are used at the customer’s own risk. A secondary ejection system must always be used. The warranty does not cover:
- Malfunctions and consequential damage caused by a malfunction.
- Wearing parts such as batteries, power cables, adapters, and lamps.
- Improper, non-contractual, or unlawful storage, adjustment, or use.
- Use of incompatible spare parts or accessories.
- Failure to maintain the product, or modifications or repairs by the customer or a third party.
- Events outside CTS’s control, including natural hazards, moisture, falls, and impacts.
The customer must inspect the product promptly and report visible or hidden defects in writing or electronically within ten days after the defect is discovered or should reasonably have been discovered. Warranty claims expire two years after the product is handed over for shipment. The customer is responsible for showing that the inspection, notification, and limitation periods were met.
Warranty claims do not entitle the customer to withhold outstanding payments. CTS decides how a valid warranty claim is handled, including repair or replacement. The customer pays the cost of returning the product to CTS. The customer has no right to rescind the contract or arrange substitute performance through a third party. To the extent permitted by law, CTS excludes liability for damage caused by product defects, including direct and indirect consequential damage and lost profit, and excludes liability for negligence.
Assignment and pledging
Claims held by the customer under the purchase contract may not be assigned or pledged without the express written consent of CTS.
CATS Flights
By using CATS Flights, you agree to this section. CATS Flights is provided for flight-log analysis, visualization, sharing, and record keeping. It is not a substitute for launch safety procedures, certified instrumentation, engineering judgment, or regulatory compliance.
Accounts
You may sign in with Google or a passwordless email link. You are responsible for maintaining access to your Google account or email inbox and for activity performed through your account. CATS Flights does not store account passwords. You may delete your account from the account page.
Your content
You remain responsible for the flight logs, photos, profile information, flight-group names and descriptions, and links you upload. You must have the rights and permissions needed to store and share that content. Do not upload unlawful, harmful, misleading, abusive, or privacy-invasive material.
Published flights are public. Anyone may view them and download their original .cfl files. Unlisted links may be opened and downloaded by anyone who receives the complete link until it expires or is revoked. You are responsible for choosing an appropriate visibility and share duration.
Flight groups and their approved published flights are public. You may apply to add your published flights to another user's group. Group owners may approve, reject, or remove memberships, and CTS administrators may edit or remove group content and memberships when needed to operate or moderate the service.
Availability and storage
CATS Flights is provided “as is” and “as available.” There are no uptime or availability guarantees. The service may be interrupted, changed, suspended, restricted, or discontinued at any time, with or without notice.
Keep your own copies of flight logs and other important content. Do not rely on CATS Flights as your sole record store, backup, safety system, or source of operational information.
Limits and enforcement
The service may enforce file, account, traffic, sharing, and storage limits. Abandoned uploads and expired guest shares are deleted automatically. CTS may restrict access or remove content when needed to protect the service, address abuse or security risks, comply with law, or enforce these terms.
Liability
To the maximum extent permitted by law, CTS is not responsible for losses arising from service outages, unavailable or deleted content, inaccurate visualizations or modeled weather, sharing links, third-party services, or decisions made using CATS Flights.
Privacy and final provisions
Personal data is processed according to the CATS Privacy Policy. CTS may update these terms by publishing a revised version on this website. If a provision is invalid or unenforceable, the remaining provisions remain effective, and the affected provision is replaced by one that most closely reflects its intended purpose.
These terms are governed exclusively by Swiss law. The United Nations Convention on Contracts for the International Sale of Goods is excluded. The exclusive place of jurisdiction is the registered office of CTS, although CTS may also bring a claim at the customer’s registered office. Proceedings will be conducted in German where permitted by the court.
