Terms of service
These terms govern your use of the FlyerOS website and set out the commercial terms on which we provide the FlyerOS service. They are written to be read, not to be buried. Where you have a separate signed agreement with us for the service, that agreement carries the definitive terms and prevails over these where they differ.
“You” means the organisation using or evaluating FlyerOS and, where relevant, the individual accepting these terms on its behalf. FlyerOS is a product for businesses and other organisations. It is not offered to consumers, and these are business-to-business terms.
Last updated: 13 August 2026.
1. The website and the service
These terms apply to two things: this website, and the FlyerOS service. Use of the website is governed by these terms and by our privacy policy.
Access to the service itself is provided under a separate written agreement (the “service agreement”) that we enter into with your organisation. The service agreement, together with our service level agreement and data processing agreement, carries the definitive terms for the service. The commercial summary below reflects our standard terms; your signed agreement prevails where it differs.
2. Pricing and billing
FlyerOS is charged per active aircraft per month in pounds sterling, excluding VAT, at the tier you select. Simulators count as half an aircraft. Users, bases and non-aircraft resources are not charged. You are billed only for aircraft active during the month.
VAT is added at the prevailing rate. For customers outside the UK, VAT is handled according to the applicable rules, including the reverse charge where a valid VAT number is supplied. Published pricing is on the pricing page.
3. Price protection
Your per-aircraft price will not increase for 24 months from the day you sign.
4. Payment
Billing is monthly rolling or annual in advance, your choice, with no multi-year lock-in. Payment by invoice, purchase order or bank transfer is accepted at no additional charge; we do not add a handling fee for not paying by card.
Invoices are due within the period stated on them. If an undisputed invoice is overdue we may charge statutory interest on late commercial payments and reasonable recovery costs, and, on notice, suspend the service until payment is made. We will not treat an amount you have told us in good faith is genuinely in dispute as overdue while we work it through with you.
5. No add-on modules
The tier you buy is complete. We do not hold features back within a tier to sell separately.
6. Term, cancellation and suspension
The minimum commitment is one month. You may cancel with effect from the end of your current billing month; we do not tie you into a notice period beyond that.
We may suspend or, on reasonable notice, end access if an account is materially in breach of these terms or the service agreement, is used unlawfully, or puts the security or availability of the service for other customers at risk. Where we can, we will warn you and give you a chance to put things right first.
7. Your data, export and deletion
Your records and files remain yours. You may export all of them, in usable formats, at any time, including after your agreement ends, at no cost and without a notice period.
How we handle the personal data within your account is set out in our data processing agreement, under which your organisation is the controller and FlyerOS is the processor. On the end of your agreement we return or delete data as you direct, reconciled with the retention a training organisation is itself required to keep.
8. Acceptable use
You agree to use FlyerOS lawfully, and not to:
- attempt to gain unauthorised access to the service, other customers’ data, or the systems it runs on;
- probe, scan or test the vulnerability of the service except under a testing arrangement we have agreed in writing;
- interfere with or disrupt the integrity or availability of the service for others;
- copy, resell or provide the service to a third party except as your agreement permits;
- reverse-engineer or attempt to extract the source code of the software, except to the extent the law expressly allows; or
- upload unlawful content or anything that infringes the rights of others.
Responsible disclosure of a security issue is welcome and is covered on our security page.
9. Intellectual property
FlyerOS, the software, its design and the FlyerOS name and marks are owned by us or our licensors. We grant your organisation a non-exclusive, non-transferable right to use the service for its own operations for the term of the agreement. Nothing in these terms transfers ownership of the software to you.
You keep all rights in the data and content you put into FlyerOS. You grant us only the limited rights needed to host and run the service for you, and to keep it secure. If you send us feedback or suggestions, we may use them to improve the product without obligation to you.
10. Confidentiality
Each of us may learn confidential information about the other in the course of the relationship. Each of us agrees to keep the other’s confidential information in confidence, to use it only to perform the agreement, and to protect it as we would our own. This does not apply to information that is public through no fault of ours, was already known, or must be disclosed by law, provided that where lawful we tell the other party first.
11. Availability and service levels
We aim to keep FlyerOS available and to be honest when it is not. Our availability commitment, status reporting and service credits are set out in the service level agreement, and live status is on the status page.
12. No regulatory warranty
FlyerOS is designed to help you operate your own approved or declared procedures. It does not itself confer regulatory compliance, certification or approval, and we make no such warranty. Responsibility for meeting the requirements of the CAA, EASA or any other authority remains with your organisation and its accountable people.
13. Warranties and disclaimers
We provide the service with reasonable skill and care. To the extent the law allows, and except as expressly stated in these terms or your service agreement, the service is provided without other warranties, whether express or implied, including implied warranties of satisfactory quality or fitness for a particular purpose.
14. Limitation of liability
Nothing in these terms limits or excludes either party’s liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything that cannot lawfully be limited or excluded.
Subject to that, neither party is liable for loss of profit, revenue, goodwill, or anticipated savings, or for indirect or consequential loss, arising out of or in connection with the service.
Subject to the above, each party’s total liability arising in any twelve-month period is limited to the fees paid or payable for the service in that period. Your service agreement may set a different cap, in which case that cap applies.
15. Third-party services
FlyerOS can connect to third-party services you choose to use, such as weather data, electronic signature, mapping and accounting exports. Those services are provided by the third parties under their own terms, and we are not responsible for them. Where a third-party service is unavailable or changes, we will do what is reasonable to keep FlyerOS working around it.
16. Changes to the service and to these terms
We improve FlyerOS continuously and may change how features work. We will not make a change that materially reduces the core function you rely on without telling you. We may update these terms from time to time; the current version is always on this page, with the date it was last updated. Material changes affecting the service are handled under your service agreement.
17. General
If any part of these terms is found to be unenforceable, the rest stands. A delay in enforcing a term is not a waiver of it. Neither party is liable for failure caused by events beyond its reasonable control. You may not assign these terms without our consent; we may assign them to a group company or in connection with a reorganisation or sale of the business. These terms, with your service agreement and the documents they reference, are the entire agreement between us on their subject.
18. Governing law and jurisdiction
These terms and any dispute arising from them are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction.
