Terms of Service

Previous version: 31 July 2026. Summary of changes at the end of this page.

These Terms of Service ("Terms") are a binding agreement between you and Alexma, trading as FlightBrief, CVR 30954580, Markkrogen 8, 2860 Søborg, Denmark ("Alexma", "we", "us", "our"). They govern your use of FlightBrief at flightbrief.io, the FlightBrief iOS app and the FlightBrief Android app (together, the "Service").

You must accept these Terms to create an account. You accept them by ticking the acceptance box at sign-up. If you do not accept them, do not create an account and do not use the Service.

In plain language: this is the contract between you and us. You agree to it when you tick the box at sign-up.

1. Who may use FlightBrief

1.1. You must be at least 18 years old and legally able to enter into a contract.

1.2. FlightBrief is built for licensed pilots and other qualified flight crew. By creating an account you confirm that you have the training and qualifications to evaluate aeronautical information yourself, and that you will use the Service only as a supplementary aid.

1.3. You must give accurate information when you sign up, keep your login details secret and tell us at hello@flightbrief.io if you think someone else has accessed your account. You are responsible for everything done through your account.

1.4. One account is for one person. You may not share your account.

In plain language: you must be 18+, a qualified crew member, and the only person using your account.

2. What FlightBrief does

2.1. FlightBrief reads an Operational Flight Plan (OFP) you upload or photograph, fetches weather, METAR/TAF, SIGMET and NOTAM information from third-party providers, compares planned figures with aircraft data held in your fleet's profile, and produces an advisory Go / Caution / No-Go summary, a written briefing and an optional passenger card.

2.2. Parts of the Service are generated by artificial intelligence. The reading of OFP images, the written briefing, the passenger card text and some summaries are produced by AI models (currently from Anthropic). AI output can be wrong, incomplete or invented, even when it looks confident.

2.3. We may change, add or remove features at any time. We will not remove a core feature of a paid plan during a billing period you have already paid for without offering a pro-rata refund.

In plain language: FlightBrief reads your OFP, fetches weather and NOTAMs, and gives you an AI-assisted summary. AI can be wrong.

3. Advisory only - no reliance for operational decisions

3.1. Every output of the Service is for information only and is not authoritative. FlightBrief is not an approved source of aeronautical information. It is not a flight-planning, dispatch, performance, mass-and-balance or navigation system, and it is not certified or approved by any aviation authority for operational use.

3.2. The Pilot in Command keeps full authority and sole responsibility for the flight, including all planning, fuel, performance, weather, alternate and go/no-go decisions.

3.3. The Service never replaces: the official OFP; ATIS; ATC; official NOTAMs and meteorological briefings; the AIP; your operator's Operations Manual, SOPs and approved performance and loading data; the Aircraft Flight Manual, MEL/CDL; dispatch; applicable regulations; or your own judgement. Where FlightBrief differs from any of these, they govern.

3.4. You must check every figure against authoritative sources before you rely on it. You must not use FlightBrief as the sole or primary basis for any operational decision, and you agree that you do not and will not rely on it for that purpose.

In plain language: FlightBrief is a second pair of eyes, never the official source. You are the captain and you decide.

4. Known limitations - please read

You understand and accept that:

4.1. Third-party data. Weather, METAR, TAF, SIGMET, forecasts, NOTAMs, aircraft and airport data come from third parties we do not control (see the Privacy Policy for the list). They may be inaccurate, incomplete, delayed, outdated or missing.

4.2. Weather differs from forecast. Actual weather can and often does differ from any forecast, including forecasts shown in FlightBrief.

4.3. OFP reading can be wrong. OFP values are read by AI from an image. The AI may misread, miss or invent values (for example weights, fuel, times, registrations or alternates), especially from blurred, cropped or unusual formats.

4.4. Verdicts and summaries can be wrong.A Go, Caution or No-Go verdict, a briefing or a passenger card may be wrong, may miss a hazard or may flag a hazard that does not exist. A "Go" never means a flight is safe or legal.

4.5. Airspace and minima are simplified. Any airspace, VFR, weather-minima, alternate or legal-minima logic is simplified and may not match the rules, approvals or operator minima that apply to you.

4.6. Fleet aircraft data. Aircraft limits may be entered by your Fleet Commander or, where no profile has been completed, drawn from unofficial sources. They may be wrong or out of date.

4.7. Availability. The Service may be unavailable, interrupted, slow or return partial results, for example because of outages, maintenance, network problems or failures at our hosting, AI, weather or NOTAM providers. We give no uptime or availability guarantee and no service level.

4.8. Offline copies are not live. Briefings saved on your device for offline use are a snapshot taken when they were created. They are not updated and may be out of date by the time you read them.

In plain language: data can be wrong or late, weather changes, AI can misread, verdicts can be wrong, rules are simplified, the Service can go down, and offline copies are old.

5. Plans

5.1. Trial. A one-time allowance of free briefings. It does not turn into a paid subscription automatically.

5.2. Pilot and Pilot Pro. Paid subscriptions, monthly or yearly, with the briefing limits and features shown on our pricing page or in the app at the time of purchase.

5.3. Airline / fleet licences. Provided to an operator under a separate agreement. A licence is issued per pilot and may be revoked by the operator or us when that agreement ends. If your access comes from an airline licence, the operator - not you - pays for it, and these Terms still apply to your use.

5.4. Prices, limits and features are those shown at the point of purchase. Your plan follows your account on every platform, but a subscription is managed and billed where you bought it (see section 6).

6. Payment, renewal, cancellation and refunds

6.1. Automatic renewal. Paid subscriptions are charged in advance and renew automatically for the same period at the then-current price until you cancel. You can cancel at any time; cancellation takes effect at the end of the current paid period and you keep access until then.

6.2. Bought on the web (Stripe)

• Payment is processed by Stripe. We do not see or store your full card details.
• Cancel at any time under Account -> Manage subscription on flightbrief.io (Stripe Customer Portal).
• Right of withdrawal (consumers in the EU/EEA). If you are a consumer, you may withdraw from a web purchase within 14 days of buying it by emailing hello@flightbrief.io. If you asked us to start the Service during those 14 days, we may deduct a proportionate amount for the part you used.
• Apart from that, and apart from any other rights you have by law, we do not refund partial periods.
• Price changes. We will tell you by email at least 30 days before a price increase applies to your next renewal. If you do not agree, cancel before the renewal date.
• Failed payments. If a renewal payment fails we may retry it and pause paid features until it succeeds.

6.3. Bought in the iOS app (Apple In-App Purchase)

• Payment is charged to your Apple ID at confirmation of purchase.
• The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Your Apple ID is charged for renewal within 24 hours before the end of the current period.
• Manage or cancel in your Apple ID settings(Settings -> your name -> Subscriptions), or from Settings -> Manage subscription in the app.
• Refunds are handled by Appleunder Apple's terms (reportaproblem.apple.com). We cannot issue refunds for App Store purchases.
• Price changesare notified and, where required, confirmed through Apple under Apple's rules.

6.4. Bought in the Android app (Google Play Billing)

• Payment is charged to your Google Play account at confirmation of purchase.
• The subscription renews automatically until cancelled. Cancel at any time before the renewal date.
• Manage or cancel in Google Play -> Payments & subscriptions -> Subscriptions.
• Refunds are handled by Google under Google Play's refund policies.
• Price changesare notified and, where required, confirmed through Google Play under Google's rules.

6.5. RevenueCat. In-app purchases on iOS and Android are processed for us by RevenueCat, Inc., which tells us which plan you have bought so we can unlock it on your account.

6.6. Taxes. Prices include VAT where the law requires prices to be shown with VAT.

In plain language: subscriptions renew until you cancel. You cancel where you bought - our website, Apple or Google. Apple and Google handle their own refunds.

7. Deleting your account and your subscription

7.1. You can delete your account at any time in the iOS app (Settings -> Delete account), on the web (Account -> Delete account), or by email. See Delete your account.

7.2. Web subscriptions: deleting your account cancels your Stripe subscription immediately. No further payments are taken, and the unused part of the current period is not refunded.

7.3. App Store and Google Play subscriptions: deleting your account does NOT cancel them. You must cancel in your Apple ID settings or in Google Play yourself, ideally before you delete your account. We cannot cancel store subscriptions for you.

8. Acceptable use

You will not:

• use the Service in breach of any law, regulation or your operator's procedures, or as the sole or primary basis for an operational decision;
• copy, resell, sublicense, frame, scrape or redistribute the Service or its output for commercial purposes, except sharing passenger cards and briefings with your own crew and passengers;
• reverse-engineer, decompile or try to extract source code or models, except where the law allows it;
• bypass plan limits, device checks, rate limits or security, or use bots or automated means to create accounts or briefings;
• upload malware, unlawful content, or content you have no right to upload (including OFPs your operator does not allow you to share with third-party tools);
• interfere with or overload the Service, or try to access other users' data;
• impersonate anyone or create accounts on behalf of others without permission.

You are responsible for the content you upload and enter (OFPs, aircraft limits, crew notes) and for having the right to do so, including under your operator's rules.

9. Fleets, Fleet Commanders and crew notes

9.1. Pilots of the same company (fleet) share company data in FlightBrief. Other pilots in your company can see your first name and email address.

9.2. A Fleet Commanderis a pilot given the right to manage the company's aircraft profiles and limits and to approve crew notes. Fleet Commanders must enter aircraft data carefully and only from approved sources, but aircraft data entered by a Fleet Commander is still advisory and must be checked against approved data (section 4.6).

9.3. Crew notes you submit are visible to your Fleet Commander and, once approved, to all pilots in your company, with your name as the author. Do not post personal data about others, confidential operator information you are not allowed to share, or anything unlawful.

9.4. We may remove crew notes or aircraft data that break these Terms.

10. Intellectual property and licence

10.1. The Service, including the software, apps, design, text and logos, belongs to us or our licensors.

10.2. Subject to these Terms, we give you a personal, non-exclusive, non-transferable, revocable licence to use the Service and to install and use the FlightBrief apps on devices you own or control, for your own flight preparation.

10.3. Your content stays yours. You give us a worldwide, non-exclusive licence to store, process and display the content you submit (OFPs, aircraft data, crew notes) only to run and improve the Service, and - for crew notes and aircraft data - to show it to your company as described in section 9. Aircraft data you add for your fleet may remain available to your fleet after you leave, without your name.

10.4. Third-party data (weather, NOTAMs, images, logos) belongs to its providers and is shown under their terms.

10.5. If you send us feedback or ideas, we may use them without obligation to you.

11. Suspension and termination

11.1. You may stop using the Service and delete your account at any time (section 7).

11.2. We may suspend or close your account, with notice where reasonable, if you seriously or repeatedly breach these Terms, if we must do so by law, or to protect the Service or other users. If we close your account without a breach by you, we refund any prepaid unused period of a web subscription.

11.3. Sections 3, 4, 10, 12, 13, 14, 20 and 21 survive termination.

12. No warranty

12.1. To the fullest extent permitted by law, the Service and all output are provided "as is" and "as available", with all faults and without any warranty - express, implied or statutory - including any warranty of accuracy, completeness, timeliness, availability, merchantability, fitness for a particular purpose, or non-infringement.

12.2. We do not warrant that the Service will be uninterrupted, timely, secure or error-free, that any output is correct, or that defects will be fixed.

12.3. This section does not limit any statutory rights you have as a consumer that cannot be excluded (see 13.4).

13. Limitation of liability

13.1. Use of the Service is entirely at your own risk. To the fullest extent permitted by law, we are not liable for any loss or damage arising from or related to your use of, inability to use, or reliance on the Service, any output, or any third-party data, including any operational, safety, regulatory, disciplinary or employment consequence, delay, diversion, fuel or performance event, incident, accident, injury, damage to aircraft or property, or fine.

13.2. To the fullest extent permitted by law, we are not liable for any indirect or consequential loss, loss of profit, revenue, income, business, goodwill or data, or punitive damages.

13.3. To the fullest extent permitted by law, our total liability for all claims in any 12-month period is limited to the greater of (a) the amount you paid us for the Service in the 12 months before the event giving rise to the claim, and (b) EUR 100.

13.4. What we do not exclude. Nothing in these Terms excludes or limits our liability: (a) for death or personal injury caused by our negligence, where such exclusion is not permitted; (b) for gross negligence or intent (grov uagtsomhed eller forsæt); (c) for fraud; (d) under mandatory product-liability law; or (e) in any other way that cannot lawfully be excluded or limited, including mandatory rights you have as a consumer under Danish and EU law. If you are a consumer, sections 12 and 13 apply only as far as consumer law allows.

13.5. These limits also protect our employees, contractors and suppliers.

In plain language: you use FlightBrief at your own risk and we do not pay for operational consequences. We can't exclude what the law won't let us exclude - gross negligence, intent, injury and your mandatory consumer rights.

14. Indemnity

You will compensate us (indemnify us) for any third-party claims, losses and reasonable costs, including legal costs, that arise from your misuse of the Service, your breach of these Terms or of the law, content you uploaded without the right to do so, or your use of the Service as a basis for an operational decision. If you are a consumer, this applies only to the extent you are at fault and as far as consumer law allows.

15. Third-party services and links

16.2. We may change these Terms for valid reasons, such as changes in law, in the Service, in our providers or in pricing. We will give you at least 30 days' notice of material changes by email and/or in the app, except where a change is required sooner by law or is purely in your favour.

16.3. For material changes we may ask you to accept the new Terms the next time you sign in. If you do not accept, you may stop using the Service and delete your account; for a web subscription we will refund any prepaid unused period on request.

17. Privacy

Our Privacy Policy explains how we use your personal data. It is information, not part of this contract.

18. Apps from the App Store and Google Play

18.1. The iOS app is distributed through Apple's App Store and the Android app through Google Play. Your use of the store is also subject to the store's own terms. Where these Terms conflict with the store's mandatory usage rules, the store's rules apply.

If you downloaded the app from the Apple App Store, these terms apply in addition. For the iOS app, the Apple Licensed Application End User License Agreement (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/) also applies; where it conflicts with these Terms, these Terms prevail to the extent Apple's rules allow, except for 19.1-19.7 below, which always apply.

19.5. Product claims. We, not Apple, are responsible for addressing any claims by you or a third party relating to the app or your possession or use of it, including (i) product liability claims; (ii) any claim that the app fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy or similar legislation.

19.6. Intellectual property.If a third party claims that the app or your possession and use of it infringes that third party's intellectual property rights, we, not Apple, are solely responsible for the investigation, defence, settlement and discharge of that claim.

19.7. Legal compliance.You confirm that (i) you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.

20.2. If we do not enforce a right immediately, we do not give it up.

20.3. You may not transfer these Terms. We may transfer them to a company that takes over the Service, if your rights as a consumer are not reduced.

20.4. These Terms are written in English. If we provide a translation, the English version governs to the extent the law allows.

20.5. These Terms (with any separate airline agreement) are the whole agreement about the Service.

21. Governing law and disputes

21.1. These Terms are governed by Danish law, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods.

21.2. The Danish courtshave jurisdiction, with the court of Alexma's registered office as the first instance where the law allows.

21.3. If you are a consumer, this choice of law and venue does not deprive you of the protection of the mandatory rules of the country where you live, and you may also bring proceedings in the courts of that country. Consumers in Denmark may complain to the Danish Consumer Complaints Board (Nævnenes Hus, naevneneshus.dk).
