1. Acceptance
By downloading, installing or using Flight Log ("the App"), you agree to these Terms of Service ("Terms"). If you do not agree, do not use the App. These Terms form a binding agreement between you and Zukasoft ("we", "us", "our").
2. Licence
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use Flight Log on Apple devices that you own or control, subject to these Terms and Apple's standard End User Licence Agreement (EULA) for App Store-distributed software.
3. Restrictions
You agree not to:
- Reverse-engineer, decompile, or disassemble the App except to the extent expressly permitted by applicable law
- Resell, rent, sublicense, or transfer your access to the App or any subscription
- Use the App for unlawful purposes or to violate aviation regulations
- Circumvent the App's free-tier limit or any subscription gating
- Use the App to operate a commercial logbook service for third parties without our written agreement
4. Subscriptions and purchases
4.1 Plans
Flight Log offers a free tier and paid plans (Monthly, Yearly, Lifetime, and Crew Pro). Current pricing is shown in the App and on our website. Pricing is subject to change with notice. Existing subscribers retain their current price for the duration of an active billing cycle.
4.2 Billing
All subscriptions and purchases are processed by Apple through the App Store. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew at the end of each billing period unless you turn off auto-renewal at least 24 hours before the period ends. You can manage and cancel subscriptions in your Apple ID settings.
4.4 Refunds
Refunds for App Store purchases are handled exclusively by Apple under its refund policy. We cannot issue refunds directly. If you believe a refund is warranted, contact Apple Support.
5. Aviation disclaimer — read this carefully
Flight Log is a personal record-keeping and reference tool. It is not a certified means of regulatory compliance. Pilots remain solely responsible for meeting their operator's official record-keeping requirements and the limits set by their applicable aviation authority.
Specifically:
- The Flight Time Limit (FDP) calculations in the App are best-effort implementations of EASA ORO.FTL.205 and FAA Part 117. They are intended to assist your awareness of legal limits but they are not authoritative. Your operator's official planning system, your operations manual, and your aviation authority's published rules supersede any value displayed in the App.
- The recency tracker (FAR 61.57) is informational. The official record of your currency is your operator's training records and your personal logbook as recognised by your authority.
- Certificate expiry alerts are reminders. The legal record of your medical, type rating and recurrent training is held by your authority and your training organisation. Do not rely solely on the App's notifications to maintain currency.
- The 3D map view is illustrative. It is not a navigation tool, not certified for flight planning, and not for use in flight.
- The PDF logbook export is for personal use and informal sharing. It is not certified, signed by an inspector, or accepted as a primary regulatory record by any authority unless your authority has separately approved it.
You agree that Zukasoft is not liable for any consequences arising from reliance on App outputs for regulatory or operational decisions. Always confirm critical numbers with your operator's authoritative system.
6. Intellectual property
The App, including all source code, designs, copy and trademarks, is the property of Zukasoft and protected by international copyright and trademark law. The data you create in the App (flight entries, certificates, signatures) belongs to you. We claim no ownership over your content and never see it.
7. Privacy
Our handling of personal data is governed by our Privacy Policy, which is part of these Terms. The summary: we hold no personal data; your records live in your private iCloud.
8. Limitation of liability
To the maximum extent permitted by law, Zukasoft shall not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of profits, revenue, data or use, arising out of or in connection with your use of the App. Our total liability under these Terms, in aggregate, shall not exceed the amount you paid for your most recent subscription period or one hundred (100) US dollars, whichever is lower.
Some jurisdictions do not allow exclusions of certain warranties or limitations of liability, so the above may not apply to you.
9. Termination
You may stop using the App at any time and uninstall it. Active subscriptions continue until the end of the current billing period and can be cancelled in your Apple ID settings.
We may suspend or terminate your access to the App if you breach these Terms in a way that materially harms our service or other users — primarily, reverse-engineering, fraudulent purchases, or attempting to bypass paywalls. Termination does not relieve you of obligations accrued before termination.
10. Governing law
These Terms are governed by the laws of the Republic of Türkiye. Any dispute arising under these Terms shall be subject to the exclusive jurisdiction of the courts of Istanbul, Türkiye, except that we may seek injunctive relief in any competent court.
If you are a consumer in the European Union, the United Kingdom, or another jurisdiction with mandatory consumer-protection laws, you retain the protections of the law of your habitual residence.
11. Changes to these Terms
We may update these Terms from time to time. The current version will always be at this URL with the "Last updated" date at the top. Material changes will be announced via an in-app notice or App Store update notes. Continued use of the App after a change constitutes acceptance of the revised Terms.
