Agreement
These Terms of Service (“Terms”) apply when you use RotorLog: the iOS, iPadOS and macOS app, the web app at rotorlog.com/app, and the desktop (Windows) and Android applications (together, the “Service”). The Service is provided by OOS (“OOS”, “RotorLog”, “we”, “us”, “our”), a company registered with the Netherlands Chamber of Commerce under KVK number 42109194 (see our Legal Notice).
By creating an account or using the Service, you agree to these Terms. If you do not agree, please do not use the Service. If you use the Service on behalf of an organisation, you confirm you are authorised to bind that organisation to these Terms.
Who can use RotorLog
You must be at least 16 years old to create an account. RotorLog is a professional tool intended for pilots and aviation organisations, and is not directed at children.
Your licence to use RotorLog
We grant you a personal, non-exclusive, non-transferable, revocable licence to use RotorLog to keep your pilot logbook, in accordance with these Terms and, for the mobile apps, the usage rules of the store you obtained the app from. You may not resell, sublicense, copy, rent or lease the Service, make it available to others as your own product, or remove any proprietary notices.
Your account
You are responsible for keeping your sign-in credentials safe and for activity under your account. Keep your account email current so we can reach you, and tell us right away if you think your account has been compromised. We offer passkeys and two-factor authentication to help you keep your account secure, and we encourage you to use them.
Your content
Your logbook data belongs to you. You grant us only the limited permissions needed to store, sync, back up and display it for you, and, when you choose to use an AI feature, to process the relevant data through our AI providers to produce your result. We do not claim ownership of your flight records, and you can export them at any time.
You are responsible for the content you enter and for having the right to record it, including the names of other people you add (such as crew). Our handling of your personal data is described in our Privacy Policy.
Acceptable use
You agree to use RotorLog lawfully and not to misuse it. In particular, you must not attempt to disrupt, overload, reverse engineer or gain unauthorised access to the Service, abuse the AI features or circumvent usage limits, or use the Service to process content you have no right to. Our full Acceptable Use Policy forms part of these Terms.
RotorLog is a record-keeping aid
RotorLog helps you keep and analyse your records, but the pilot remains solely responsible for meeting every legal logbook, licensing, currency and duty requirement that applies to them.
Always verify entries, totals and currency and duty calculations against your official records and the applicable regulations. Do not rely on RotorLog as your sole source for regulatory compliance. AI-generated answers and imported flights can contain errors, so review them before saving.
Subscriptions and billing
RotorLog offers a free tier and paid plans (RotorLog Pro, and RotorLog AI as a separate add-on that raises AI usage limits). Paid plans are available as recurring subscriptions and, in some cases, as a one-time purchase.
- Prices. The price, billing period and any trial shown to you at the point of purchase (in your store and for your country) apply. Prices may differ between platforms and regions and may change over time; any change to a recurring price is handled in accordance with the rules of the store you subscribed through. Prices are shown in the currency of the country you are browsing from, and are the prices charged at checkout. If we do not sell in your local currency, prices are shown and charged in US dollars. Your bank or card issuer may apply its own conversion rate or fees.
- Organisation licences. Organisation Pro licences are priced at around 25% below the standard RotorLog Pro price for your region. Each licence is rounded to a clean amount in your local currency, so the exact saving varies by plan and region, usually between 20% and 28%. The price you pay is always shown before you confirm.
- Where you buy. On iOS, iPadOS and macOS, purchases are billed by Apple through the App Store; on the web and Windows, by us through Stripe. The Android app does not sell subscriptions and contains no in-app purchases: to subscribe you use another platform that does sell them, namely the web at rotorlog.com or the Windows app, and your subscription then applies in the Android app as well.
- Trials and renewal. A 3-day free trial is available on personal monthly and yearly plans; where a trial applies, it converts to a paid subscription unless you cancel before it ends. Subscriptions renew automatically for the same period until cancelled.
- Cancelling. You can cancel at any time, through your App Store subscription settings, or through the Stripe customer portal for web, Windows and Android purchases. Access continues until the end of the period you have paid for.
- Refunds. Refunds are handled by the store you purchased through and under its policy. See our Refund & Cancellation Policy for details, including EU withdrawal rights.
AI features
The AI features are optional and are off until you use them. When you use them, certain data is processed by third-party AI providers as described in our Privacy Policy. AI output is generated automatically, may be inaccurate or incomplete, and is provided for you to review; you are responsible for checking it before saving or relying on it. Usage limits apply and may change.
Sharing and organisations
RotorLog lets you share part of your logbook through share links, connections with other pilots, or membership of an organisation. You control the scope of every share and can pause or revoke it. When you share data, you are responsible for choosing an appropriate scope and recipient. Organisations that use RotorLog to manage pilot data do so under our Organisation and Data-Processing Terms.
Apps obtained through Apple or Google
The following applies where you obtain the app through the Apple App Store or Google Play, in addition to those stores' own terms.
Apple App Store
These Terms are between you and OOS only, and not with Apple. OOS, not Apple, is solely responsible for the app and its content. Apple has no obligation to furnish any maintenance or support for the app. To the maximum extent permitted by law, Apple has no warranty obligation with respect to the app; in the event of any failure of the app to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) you paid for the app, and, to the maximum extent permitted by law, Apple has no other warranty obligation whatsoever. OOS, not Apple, is responsible for addressing any claims relating to the app, including product-liability, regulatory, consumer-protection and intellectual-property claims, to the extent not attributable to Apple. You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist-supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, have the right to enforce them against you. For questions or complaints about the app, contact OOS at legal@rotorlog.com.
Google Play
Where you obtain the app through Google Play, your use is also subject to the Google Play Terms of Service. The Android app is distributed through Google Play but does not sell anything: it contains no in-app purchases, and Google does not process any payment for RotorLog. Subscriptions are bought on the web at rotorlog.com and are billed by us through Stripe.
Availability and changes to the Service
We work to keep the Service available and reliable, but we may add, change, suspend or remove features, and we may perform maintenance. If we make a material adverse change, or discontinue the Service, we will give you reasonable notice so you can export your logbook.
Disclaimer
The Service is provided “as is” and “as available.” To the maximum extent permitted by law, we disclaim all implied warranties, including fitness for a particular purpose, and we do not warrant that the Service will be uninterrupted, error-free, or sufficient for any regulatory purpose. Nothing in these Terms excludes or limits rights that cannot be excluded or limited under the mandatory law that applies to you, including consumer law.
Limitation of liability
To the maximum extent permitted by law, we are not liable for indirect, incidental, special or consequential damages, or for lost data, profits or goodwill. Our total liability arising out of or relating to the Service is limited to the amount you paid us for the Service in the twelve months before the event giving rise to the claim. These limits do not apply to liability that cannot be limited by law, such as for death or personal injury caused by our negligence, or for fraud. Because RotorLog is a record-keeping aid, we are not responsible for regulatory, licensing or operational consequences arising from your reliance on it (see RotorLog is a record-keeping aid).
Your responsibility
You are responsible for your use of the Service and for your content. To the extent permitted by law, and except where you are acting as a consumer, you agree to hold us harmless from claims arising out of your breach of these Terms, your misuse of the Service, or your infringement of another person's rights.
Termination
You can stop using RotorLog and delete your account at any time from inside the app. We may suspend or terminate accounts that violate these Terms or abuse the Service, and, where proportionate, we will give you notice and an opportunity to put things right. On termination, the licence granted to you ends; sections that by their nature should survive (such as content ownership, disclaimers, liability and governing law) continue to apply.
Governing law and disputes
These Terms are governed by the laws of the Netherlands, without regard to conflict-of-law rules. Disputes will be subject to the competent courts of the Netherlands, unless mandatory consumer law in your country of residence gives you the right to bring proceedings in your local courts or to rely on your local law. Nothing in these Terms affects your mandatory statutory rights as a consumer.
Changes to these Terms
We may update these Terms as RotorLog evolves. When we do, we will update the date at the top of this page, and for significant changes we will let you know in the app or by email. Continuing to use RotorLog after a change takes effect means you accept the updated Terms; if you do not agree, you may stop using the Service and cancel any subscription.
