Terms of Service

1. The service

KármánLogs provides a digital pilot logbook and related aviation tools. We may add, change, or remove features over time. Some features require an active subscription.

2. Eligibility and age

You must be old enough to form a binding contract in your country to hold an account. The App is not intended for children under 13, and we do not knowingly allow them to create accounts. If you are a minor in your country (for example, a student pilot under the age of digital consent), you may use the App only with the involvement and consent of a parent or guardian, who accepts these Terms on your behalf. See our Privacy Policyfor more on how we handle minors’ data.

3. Your account

To use most features you create an account. You agree to provide accurate information, keep your login credentials secure, and be responsible for all activity under your account. Notify us promptly at support@karmanlogs.com if you believe your account has been compromised. You are responsible for maintaining your own backups of important data where the App allows export.

4. Subscriptions, billing, and cancellation

KármánLogs offers the following subscription tiers, billed annually:

• Free for student pilots, with no feature limitations for the first 100 hours.
• Private
• Commercial
• ATP

Current pricing for each tier is shown in the App and on the App Store at the time of purchase, and may vary by region. Prices may change; any change will apply to your next renewal, not your current term.

Paid subscriptions are auto-renewable and are sold through the Apple App Store. The following applies:

• Payment is charged to your Apple ID account at confirmation of purchase.
• Your subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period.
• Your Apple ID account is charged for renewal within 24 hours before the end of the current period.
• You can manage or cancel your subscription, and turn off auto-renewal, in your Apple ID account settings.
• Refunds are handled by Apple in accordance with Apple’s policies. We do not process payments and cannot issue refunds directly.

If you cancel, you keep access to paid features until the end of your current billing period.

5. Your content and data

You own the flight and logbook data you create or import (“Your Content”). You grant us a limited license to store, process, sync, and display Your Content solely to operate the App and provide the service to you. We do not sell Your Content and we do not use it for advertising. Our handling of Your Content is described in our Privacy Policy.

You are responsible for the accuracy of Your Content and for ensuring you have the right to enter any information you provide.

6. Data, storage, backups, and loss of data

We have designed KármánLogs to keep your logbook as safe as we reasonably can. Your data is stored in your own Apple iCloud account, encrypted by Apple in transit and at rest, synced across your devices, with automatic backups and one-tap CSV export so you can keep your own copy at any time.

Even so, no app, device, or cloud service can guarantee that data will never be lost, corrupted, delayed, or become unavailable. Storage and sync rely on Apple iCloud and your device, which are outside our control, and problems can arise from software issues, device failure, account or network problems, or your own actions. Because of this:

• You are responsible for keeping your own independent backups of any data that matters to you. We strongly recommend exporting your logbook to CSV regularly and storing that copy somewhere safe. Your official logbook and regulatory records should never exist only inside the App.
• All backup, sync, and export features are provided on a best-effort, “as is” basis, with no guarantee of availability, completeness, or accuracy.
• To the fullest extent permitted by law, KármánLogs is not responsible or liable for any loss, corruption, or unavailability of your data, however it occurs. This does not limit any rights you have under mandatory consumer law in your country.

7. Aviation and recordkeeping disclaimer

Please read this section carefully. It is important.

KármánLogs is a tool to help you record and organize your flight activity. It is not an official record, a regulatory authority, or a source of aviation, legal, or operational advice. You remain solely responsible for:

• Complying with all applicable aviation regulations, including FAA recordkeeping, currency, and certificate requirements.
• The accuracy, completeness, and legal sufficiency of your own logbook and records.
• Any decisions you make regarding flight currency, eligibility, or operations.

Do not rely on the App as your sole or official record, and do not use any information, summary, or calculation in the App for in-flight navigation or operational decision-making. Always verify against authoritative sources and your own official records. KármánLogs does not guarantee that the App satisfies any specific regulatory requirement.

8. AI-assisted features

Some features use artificial intelligence to generate responses or summaries. AI output may be incomplete, inaccurate, or out of date, and is provided for convenience only. It is not aviation, legal, or professional advice. Always verify AI output before relying on it, especially for anything affecting regulatory compliance or flight safety. Your use of AI features is also subject to our Privacy Policy, which explains how that input is processed.

9. Acceptable use

You agree not to:

• Use the App for any unlawful purpose or in violation of these Terms.
• Attempt to access accounts, data, or systems that are not yours.
• Reverse engineer, decompile, or interfere with the App except as permitted by law.
• Upload malware, scrape the service, or place an unreasonable load on our systems.
• Resell, sublicense, or commercially exploit the App without our written permission.

We may suspend or terminate access if you violate these Terms or misuse the service.

10. Intellectual property

The App, the Site, and all related software, designs, logos, and content (other than Your Content) are owned by KármánLogs or its licensors and are protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the App for your personal or professional aviation use, subject to these Terms. All rights not expressly granted are reserved.

11. Third-party services

The App relies on third-party services, including Apple iCloud and other providers described in our Privacy Policy. Your use of those services may be subject to their own terms. We are not responsible for third-party services and do not control them.

12. Disclaimer of warranties

The App and Site are provided “as is” and “as available,” without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or that data will never be lost. To the extent any warranty cannot be disclaimed under applicable law, it is limited to the minimum required by that law.

13. Limitation of liability

To the fullest extent permitted by law, KármánLogs and its owners and affiliates will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, currency, or records, arising from or related to your use of the App. Our total liability for any claim relating to the App will not exceed the amount you paid us for the subscription in the 12 months before the claim, or 50 US dollars if you paid nothing. Some jurisdictions do not allow certain limitations, so some of these may not apply to you.

14. Indemnification

You agree to indemnify and hold harmless KármánLogs and its owners and affiliates from any claims, damages, or expenses arising from your use of the App, Your Content, or your violation of these Terms or applicable law.

15. Termination

You may stop using the App and delete your account at any time. We may suspend or terminate your access if you breach these Terms, if required by law, or if we discontinue the service. On termination, your right to use the App ends. Sections that by their nature should survive termination (including ownership, disclaimers, limitation of liability, and indemnification) will survive.

16. Changes to the service and these Terms

We may modify the App or these Terms from time to time. When we make material changes to these Terms, we will update the “Last updated” date and, where appropriate, notify you in the App or by email. Your continued use of the App after changes take effect means you accept the revised Terms.

17. Governing law and disputes

These Terms are governed by the laws of the State of Florida, United States, without regard to its conflict-of-laws rules. You agree that any dispute will be resolved in the state or federal courts located in Florida, unless applicable consumer-protection law in your country gives you the right to bring proceedings elsewhere. Nothing in these Terms limits any mandatory consumer rights you have under the law of your country of residence.

18. Apple App Store terms

These Terms are between you and KármánLogs only, not with Apple, and Apple is not responsible for the App or its content. The following additional terms apply to your use of the App on Apple devices:

• Apple has no obligation to provide any maintenance or support for the App.
• If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any). To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
• Apple is not responsible for addressing any claims relating to the App, including product liability, legal or regulatory compliance, or consumer protection claims.
• Apple is not responsible for any third-party claim that the App infringes intellectual property rights.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

You also agree to comply with applicable third-party terms (such as your wireless data plan) when using the App.

19. General terms

Severability. If any provision of these Terms is found to be unenforceable or invalid, that provision will be limited or removed to the minimum extent necessary, and the remaining provisions will remain in full force and effect.

Entire agreement. These Terms, together with our Privacy Policy and any terms presented at the time of purchase, are the entire agreement between you and KármánLogs regarding the App and Site, and replace any prior agreements on that subject.

Assignment. You may not assign or transfer these Terms or your account without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganization, or sale of assets, or as otherwise permitted by law.

No waiver. Our failure to enforce any provision of these Terms is not a waiver of our right to do so later. No waiver of any term is effective unless it is in writing.
