1. Acceptance of Terms
By installing, accessing, or using the Nimble Preflight mobile application (the "App") operated by NIMBLE AERO SARLAU ("we," "us," or "our"), you ("you," "user," or "Pilot") agree to be bound by these Terms of Service ("Terms") and our Privacy Policy and Legal Disclaimer, each incorporated herein by reference.
These Terms apply to all users of the App, including users who access the App through free or paid subscription tiers.
NIMBLE AERO SARLAU is a Société à Responsabilité Limitée à Associé Unique (single-member LLC) registered under Moroccan law, headquartered in Casablanca, Morocco.
2. The Service
2.1 What the App Is
Nimble Preflight is a mobile reference tool that aggregates publicly available aviation weather, NOTAM, and flight tracking information from third-party data providers to assist pilots in preflight planning and situational awareness. The App includes the following functional categories:
- METAR, TAF, SIGMET, AIRMET, GAMET, AIREP retrieval and display
- NOTAM retrieval and decoding (airport and FIR level)
- Aviation weather charts (SIGWX, Wind/Temp, Satellite imagery)
- Decoders (METAR, TAF, SNOWTAM, GRF)
- Calculators (cold temperature altitude correction, wind components, flight timing)
- Live flight tracking for situational awareness (powered by Flightradar24)
- Pilot notes (local-only storage of ATIS, clearances, free text)
- Watchlist of airports and airport-specific data caching
2.2 What the App Is NOT
The App is not any of the following:
- An Electronic Flight Bag (EFB) under FAA Advisory Circular AC 120-76D, EASA AMC 20-25, or any equivalent regulatory framework
- A certified or approved source of aviation weather information
- A substitute for an official weather briefing service (such as 1800wxbrief.com, Leidos Flight Service, or your national equivalent)
- A flight planning system, navigation database, or airworthiness-related system
- Certified to DO-178C, DO-160, or any aviation software certification standard
The App is provided for reference and situational awareness purposes only. See our Legal Disclaimer for full details.
3. Pilot Responsibility
You acknowledge and agree that the pilot in command is solely responsible for:
- Becoming familiar with all available information concerning the flight
- Obtaining a complete and official weather briefing from an approved source before each flight
- Reviewing all applicable NOTAMs from authoritative sources for departure, destination, alternate, and en-route airports and airspace
- Verifying that all information used for flight planning is current, complete, and authoritative
- Making the final go/no-go decision based on verified, official data, not on information displayed by the App
You agree that you will not use the App as the sole source of aviation weather, NOTAM, or operational data for any flight.
NIMBLE AERO SARLAU cannot be held responsible, directly or indirectly, for any decision, action, omission, outcome, incident, accident, delay, diversion, loss, injury, or damage of any kind resulting from your use of, reliance on, or inability to use the App. The pilot in command bears sole and exclusive responsibility for all flight-related decisions. Your acceptance of these Terms includes your acknowledgment and acceptance of this non-responsibility clause.
4. Data Sources & Attribution

4.1 Third-Party Availability
The third-party services listed above operate independently and may experience outages, latency, data quality issues, or discontinuation without notice. We are not responsible for the availability, accuracy, completeness, or timeliness of data provided by these third-party sources.
5. Subscription Terms
5.1 Subscription Model
After the free trial period, continued access to the App's data services requires an active paid subscription. The App is offered on a subscription basis with two billing cadences: monthly or annual. There is no permanent free tier — once the trial ends, an active paid subscription is required to access the App's data features.
5.2 Pricing & Local Taxes
Subscription fees, applicable taxes, and the available billing periods are displayed at the point of purchase through the Google Play Store or Apple App Store. Prices vary by country and may include or exclude local taxes (VAT, sales tax, GST, or equivalent) depending on your jurisdiction and the platform's regional pricing rules. The price you pay is the price displayed at checkout in your local currency. NIMBLE AERO SARLAU does not control or set the final price paid; this is determined by the platform based on your region, applicable taxes, and platform fees.
5.3 Free Trial
The App offers a free trial of fourteen (14) days with full features. Trial duration, eligibility, conversion to paid subscription, and any promotional offers are governed by the platform (Google Play Store or Apple App Store) terms applicable to your account.
5.4 Subscription Management, Billing & Refunds
All billing, auto-renewal, cancellation, refunds, and payment disputes are governed exclusively by the platform (Google Play Store or Apple App Store) through which you purchased your subscription. NIMBLE AERO SARLAU does not process payments and cannot directly issue refunds or cancel subscriptions on your behalf. Please refer to:
- Google Play refund policy: support.google.com/googleplay
- Apple App Store refund policy: support.apple.com/HT204084
5.5 Subscription Expiry
If your free trial expires without subscription activation, or if your paid subscription lapses or is cancelled, the App's data services (weather, NOTAM, charts, flight tracking, advisories) will be disabled until you activate or renew a paid subscription. Your locally stored data (watchlist, pilot notes, cached data) is preserved on your device and will resume when you subscribe.
6. Live Flight Tracking
The App includes optional live flight tracking powered by Flightradar24 AB. By using this feature, you acknowledge and agree to the following:
6.1 Situational Awareness Only
Live flight tracking data is provided for situational awareness only. It must not be used for:
- Air traffic separation
- Collision avoidance
- Tactical flight management
- Any safety-critical operational decision
6.2 Credit Allowance
Each subscriber receives 10 flight tracking credit lookups per calendar month. Credits do not roll over. Credits reset at the beginning of each calendar month. The credit balance is associated with an anonymized device or platform account identifier (see our Privacy Policy §2.2).
6.3 Flightradar24 Terms
Use of the flight tracking feature is also subject to Flightradar24's terms and conditions and privacy policy.
6.4 Data Latency and Coverage
Flight tracking data may be delayed, incomplete, or unavailable in certain regions due to ADS-B coverage limitations or Flightradar24 service availability. Coverage gaps in oceanic, polar, and certain controlled airspaces are normal.
7. Pilot Notes
The App provides a pilot notes feature for recording ATIS, clearances, and free-text observations. The following applies:
- Device-local only: All pilot notes are stored exclusively on your device. We do not transmit, sync, or store any pilot notes on our servers.
- No auto-populate: The App does not automatically populate pilot notes from any external data source. You enter all content manually.
- No transmission to ATC: Pilot notes are a personal reference tool and have no operational link to air traffic control, aviation authorities, or any flight system.
- Loss of data: If you uninstall the App or reset your device, your pilot notes will be permanently deleted. We do not provide backup or recovery of pilot notes.
8. Prohibited Uses
You agree that you will not, and will not permit any third party to, engage in any of the following activities in connection with the App or its underlying services:
8.1 No Reverse Engineering

You may not bypass, disable, attempt to circumvent, or defeat any security or anti-abuse measure implemented by the App or its backend services.
8.4 No Derivative Works or Republishing
You may not create derivative works based on the App, its data, its visual design, or its documentation. You may not republish, redistribute, mirror, package, or wrap the App or its data in any other application, website, or service.
8.5 No Resale or Sublicensing

8.6 No Automated or Bulk Access
You may not use any robot, spider, scraper, bot, automated script, or similar means to access, monitor, or interact with the App or its backend services. Automated, bulk, or programmatic access to the App's data is prohibited.
8.7 No Use for Commercial Decision-Making by Third Parties
You may not use the App or the data it displays to provide aviation weather briefings, NOTAM bulletins, or operational planning services to third parties as a commercial service, except for use within your own employer's operational environment as a personal reference tool for your own flying.
8.8 No Misrepresentation
You may not represent the App as a certified weather source, as your employer's official preflight system, or as an EFB. You may not use the App's data in any official flight planning document, dispatch release, or regulatory filing as the primary or sole source.
8.9 Statutory Exception (EU Software Directive)
The prohibitions in §8.1 and §8.4 apply except to the extent that such restrictions are prohibited by applicable mandatory law. In particular, where you are entitled to perform acts of decompilation strictly necessary to achieve interoperability of an independently created computer program with other programs under Article 6 of EU Directive 2009/24/EC, or under equivalent statutes in your jurisdiction, those rights are preserved. Such acts must be limited to what is strictly necessary for interoperability, must be confined to the information necessary for that purpose, and may not be communicated to third parties or used for the development of a substantially similar product.
8.10 Consequences of Violation
Any violation of this Section 8 may result in immediate termination of your subscription and license to use the App, denial of access to our services, and where applicable, civil action for damages and injunctive relief. We reserve all rights and remedies available to us at law and in equity.
9. Account & Subscription Management
9.1 No User Accounts
The App does not require you to create an account with us. Subscription management is handled entirely through your Google Play or Apple App Store account.
9.2 Device Identifier
For flight tracking credit management, the App associates your usage with an anonymized device identifier or your platform-provided account token. See our Privacy Policy §2.2 for details.
9.3 Subscription Cancellation
You may cancel your subscription at any time through your Google Play or Apple App Store account settings. Cancellation takes effect at the end of the current billing period. We do not have the ability to cancel subscriptions on your behalf, as we do not control the payment systems.
10. Disclaimer of Warranties

15. Governing Law
These Terms are governed by and construed in accordance with the laws of the Kingdom of Morocco, without regard to its conflict of law principles.
For users in the European Union, European Economic Area, or United Kingdom, this choice of law does not deprive you of the protection of mandatory consumer protection laws of the country in which you habitually reside.

If informal resolution fails, any dispute arising out of or related to these Terms or the App shall be submitted to the exclusive jurisdiction of the competent courts of Casablanca, Morocco, subject to the EU/EEA/UK consumer protection carve-out in §15.
17. Severability
If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, the remaining provisions shall remain in full force and effect. The invalid provision shall be replaced by an enforceable provision that most closely reflects the original intent.
18. Entire Agreement
These Terms, together with our Privacy Policy and Legal Disclaimer, constitute the entire agreement between you and NIMBLE AERO SARLAU regarding the App and supersede all prior or contemporaneous agreements, communications, and proposals, whether oral or written.
