Wingbase provides a web-based platform for aircraft ownership management, including:

• Flight logging and tracking

$100 Hamburger

$100 Hamburger is a free, account-free mobile destination discovery service by Wingbase. It provides airport recommendations, planning estimates, and live restaurant details supplied by Google Places. Saved destinations and private saved notes are stored locally on your device. Opt-in landing suggestions and lunch-run emails, along with reports you submit, send preferences, identifiers, or report details to Wingbase as described in our Privacy Policy.

3. User Accounts

Eligibility

Wingbase is for adults. You must be 18 or older to create an account, accept an invitation, or be added to an aircraft. This applies to every role on an aircraft, including students: the student role is for adult students, and we do not offer accounts to anyone under 18.

Registration

You must provide accurate, complete, and current information during registration. You are responsible for maintaining the confidentiality of your account credentials.

Account Security

You agree to:

• Immediately notify us of any unauthorized use of your account
• Accept responsibility for all activities under your account
• Not share your account credentials with others
• Not create multiple accounts for fraudulent purposes

4. Acceptable Use Policy

You agree not to:

• Interfere with or disrupt the Service
• Reverse engineer or attempt to extract source code
• Use automated systems or software to extract data

5. Payment Terms

Fees

Wingbase is a paid subscription service. Each subscription belongs to the person who holds it: billing is per user, so each co-owner who uses Wingbase needs their own. Plans are priced by tail. Current published web plans (USD) are:

• Solo — $24/month per tail, or $240/year, for one owner.
• Partnership — $48/month per tail, or $480/year, for 2–6 owners.
• Fleet — $96/month per tail, or $960/year. Fleet is sales-led; contact us to subscribe.

Current published prices are listed on the Pricing page. Annual web plans save 17% versus paying monthly. Web subscriptions are billed through Stripe. iOS App Store subscriptions are billed through Apple at the price displayed in the App Store purchase flow. We may change prices or introduce new plans. Material changes that affect existing paid functionality will be disclosed at least 30 days in advance.

Free Trial

New web subscriptions include a 7-day free trial. No credit card is required to start the web trial. After the trial ends, continued access requires an active paid subscription. If you do not add a payment method before the trial ends, the subscription is cancelled and access ends. Any App Store introductory offer is shown and governed by Apple in the purchase flow.

Renewals

Paid subscriptions renew automatically at the end of each monthly or annual billing period unless you cancel before the renewal date. Web subscriptions renew at the then-current published web rate for the selected plan. App Store renewals and price changes are governed by Apple's subscription terms and the price Apple displays to you. You authorize us (or Apple, for App Store subscriptions) to charge the payment method on file for each renewal.

Cancellation

You may cancel at any time from Billing settings (web) or Apple Subscriptions (iOS). Cancellation takes effect at the end of the current paid period; you keep access until then. Stripe prorates web plan changes. App Store plan changes follow Apple's subscription terms.

Non-payment

If a renewal or other fee is not paid when due, we may suspend or terminate access for non-payment of fees, as described in Section 11. Outstanding amounts remain due.

6. Financial Services Disclosure

Marketplace-linked financing and insurance features are not currently available. Wingbase does not currently offer or facilitate financing, insurance quotes, or introductions to lenders, insurers, or other financial services providers.

Wingbase is not a lender, bank, or insurance provider. We do not originate loans, underwrite insurance policies, provide financial products, or provide financial, investment, insurance, or legal advice. Consult qualified professionals before making financial decisions.

Aviation Disclaimer

WINGBASE IS NOT A CERTIFIED AVIATION TOOL. Users are solely responsible for compliance with all applicable aviation regulations and safety requirements.

$100 Hamburger Disclaimer

$100 HAMBURGER IS A DESTINATION DISCOVERY AID, NOT A FLIGHT-PLANNING, WEATHER, NAVIGATION, AIRPORT-SUITABILITY, OR GROUND-ACCESS TOOL. DISTANCE, AIRBORNE TIME, FUEL, AND COST VALUES ARE ESTIMATES THAT EXCLUDE WIND, TAXI, CLIMB, MAINTENANCE, RENTAL, FEES, AND OTHER COSTS. YOU MUST VERIFY CURRENT AIRPORT STATUS, RUNWAY AND WEATHER CONDITIONS, GROUND ACCESS, AND OPERATIONAL SUITABILITY IN AN APPROPRIATE FLIGHT-PLANNING SOURCE BEFORE DEPARTURE.

Restaurant details and ground actions are provided by Google and may be incomplete, delayed, or unavailable. ForeFlight and Google services are independent third parties with their own terms and privacy practices. An algorithmic distance band does not mean a restaurant is on-field, walkable, or accessible from aircraft parking. Only a dated Wingbase-reviewed label represents a manual access review, and conditions may still change.

The "What's the craving?" food-type filter counts nearby eating places using Overture Maps open data, © Overture Maps Foundation, which includes data © OpenStreetMap contributors available under the Open Database License. Food types describe what is near a field, not the restaurant shown on each card, and may be incomplete or out of date.

• At our sole discretion for any reason

Upon termination, you may export your data within 30 days. After this period, we may delete your data except as required by law.
