These terms cover your use of the DutyFlip app and website. By creating an account you agree to them. Please also read our privacy policy, which explains how we handle your data.
Last updated: 3 November 2026
1. Who we are
DutyFlip is run by Vector and Wing Limited, a company registered in England and Wales (company number 17367147), registered office 82A James Carter Road, Bury St Edmunds, IP28 7DE, England (“DutyFlip”, “we”, “us”). You can reach us at [email protected].
2. What DutyFlip is, and isn’t
DutyFlip helps airline crew find colleagues to swap duties with, ask who is working a flight (Onboard), and message each other about it. DutyFlip is independent: it is not provided by, endorsed by or affiliated with any airline, and it is not affiliated with RosterBuster or any other roster app.
DutyFlip does not change your roster. Agreeing a swap in DutyFlip is an agreement between you and a colleague. The swap only takes effect once you have submitted it to your airline’s crewing department in the usual way and they have approved it. Until then you remain responsible for the duties on your official roster. Always cross-check your official roster.
The flight time limitation (FTL) check in the app is an aid based on the roster you imported and general rules. It is not a substitute for your airline’s own checks or your responsibility to be legal and rested for a duty.
3. Your account
- You must be a current crew member of an airline DutyFlip supports and sign up with your work email address. One account per person.
- You must be at least 18.
- Keep your sign-in codes to yourself. You are responsible for what is done from your account.
- You may delete your account at any time in Profile › Delete account. This removes your roster, offers, requests and chats.
4. Using DutyFlip fairly
You agree not to:
- import anyone else’s roster or pretend to be someone else;
- share other crew members’ contact details or roster information outside DutyFlip without their permission;
- use DutyFlip to harass, pressure or discriminate against colleagues, or to trade duties for money;
- use DutyFlip in a way that breaks your airline’s policies, your contract of employment or the law;
- copy, scrape, reverse engineer or overload the service, or try to get around its access controls.
We may suspend or close accounts that break these terms, and we may remove content that does. Where we can, we will tell you why.
5. Free, Pro and payment
Launch period. While DutyFlip grows, every feature, including Pro, is free for everyone and no payment is taken. We plan to introduce paid Pro plans around six months after launch, but the timing may change. We will tell you in the app at least 14 days before any charges begin, and nothing is ever charged unless you choose to subscribe in the App Store or Google Play.
Free. Once Pro plans start, DutyFlip stays free to use: importing your roster, offering trips, answering requests, chat, flight time limit checks, rewards and a limited number of swap requests each month (currently 1, counted per UK calendar month, including requests you later withdraw). We may change what Free includes; if we reduce it, we will tell you in the app first.
Pro. Pro adds the features shown in the app, including unlimited swap requests and alerts. When the launch period ends you move to Free unless you subscribe, or have reward time to use.
Subscriptions. Pro is planned at £1.99 a month or £19.99 a year (prices include VAT, may change before Pro starts and may vary slightly by country; the price you are shown in the store is the one you pay). Subscriptions are bought through Apple’s App Store or Google Play and are charged to the account you use there.
Renewal and cancellation. Subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before it ends. You cancel in your App Store or Google Play subscription settings, not in DutyFlip. Cancelling stops future charges; you keep Pro until the end of the period you have paid for, then move to Free.
Refunds. Because payment is taken by Apple or Google, refunds are handled under their policies and requested from them. If you are having trouble, email us and we will help where we can.
Price changes. If we change the price, the store will tell you in advance and ask you to agree before the new price applies to you.
Restoring a purchase. If you change phone, use Profile › Restore purchases, signed in to the same App Store or Google account.
6. Rewards
You can earn points by inviting colleagues and using DutyFlip’s features, and claim them for free time on Pro, whether you are on Free or Pro (currently 50 points for a month, 500 for a year). Free time claimed while you have a paid subscription starts when your current paid period ends; the app tells you the date so you can turn off auto-renewal if you wish. Points have no cash value, can’t be transferred and may be withdrawn if they were earned by breaking these terms. We may change how points are earned and what they can be claimed for; points already earned keep the value they had when earned.
7. Your content and ours
Your roster, offers, messages and profile remain yours. You give us permission to store and show them as the app needs to, as described in the privacy policy. The DutyFlip name, logo, app and website are ours; you may use the app for your own personal use as crew and not otherwise.
8. Availability and changes
We work to keep DutyFlip available and accurate, but we can’t promise it will always be. We may change or withdraw features, and we may change these terms; if a change matters to you, we will tell you in the app or by email before it takes effect. If you keep using DutyFlip after that, the new terms apply. If you don’t agree, cancel any subscription and stop using the app.
9. Our responsibility to you
Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else the law says we can’t limit. Otherwise, DutyFlip is provided as an aid: we are not responsible for a swap not being approved by your airline, for a duty being missed, for the accuracy of a roster you import, or for the actions of other crew members. Our total liability to you for any claim is limited to the amount you paid us in the 12 months before the claim.
10. Law and disputes
These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction, though if you live in Scotland or Northern Ireland you may bring a claim in your local courts. Nothing here affects your rights as a consumer under UK law.
