Terms of Service

Last updated: April 9, 2026

These Terms of Service ("Terms") govern your access to and use of the Hangar Flow software, websites, mobile apps, and services (collectively, the "Service"), provided by Hangar Flow ("we", "us", or "our"). By creating an account, signing in, or using the Service, you agree to be bound by these Terms.

If you are using the Service on behalf of a company or organization (like a maintenance shop), you represent that you have the authority to bind that organization to these Terms.

1. The Service

Hangar Flow is a workflow tool for aviation maintenance shops. It lets shop owners and technicians manage aircraft, work logs, tasks, squawks, time entries, parts inventory, and reference manuals across iPhone, macOS, and the web. The Service is provided "as a service" — you don't install it on your own servers; it runs on infrastructure we maintain.

2. Accounts and access

• You must provide accurate, current information when you sign up.
• You are responsible for all activity that happens under your account.
• You must keep your password secure and notify us immediately if you suspect unauthorized access.
• You may invite techs to your shop and grant them access. Their use of the Service is also bound by these Terms.
• One person, one account. Sharing a single login between multiple people is not permitted.

3. Subscription and billing

• The Service is offered on a recurring subscription basis. Plans, prices, and features are listed at hangarflow.com/home#pricing.
• Subscriptions are billed monthly in advance via Stripe. Your card is automatically charged at the start of each billing period until you cancel.
• All amounts are in US dollars unless otherwise specified.
• You may change your plan, update your card, or cancel at any time from the dashboard's Plan & Billing card. Cancellations take effect at the end of the current billing period.
• Refunds are governed by our Refund Policy.
• If a payment fails, we will retry the charge for up to 14 days. Continued non-payment may result in suspension of access.

4. What you can do with the Service

You may:

• Use the Service to run aircraft maintenance work for your shop.
• Upload your own maintenance manuals, work logs, and shop data.
• Invite as many technicians as you employ.
• Export your data via the support email at any time.

5. What you can't do

You may not:

• Resell, sublicense, or otherwise distribute the Service to third parties.
• Reverse-engineer the Service or attempt to extract source code.
• Upload content that infringes someone else's intellectual property rights.
• Use the Service to harass, defraud, or harm anyone.
• Probe, scan, or test the vulnerability of the Service or attempt to bypass security controls.
• Use automated systems (bots, scrapers) to access the Service in ways that disrupt normal operation.
• Violate any applicable law or regulation while using the Service.

6. Your data

You retain ownership of all data you put into the Service — aircraft records, work logs, time entries, parts inventory, manual files. We claim no ownership over your shop's data. We process and store it solely to provide the Service to you, as described in our Privacy Policy.

You grant us a limited license to host, copy, transmit, and display your data as necessary to operate the Service across your devices.

7. Aviation safety disclaimer

Hangar Flow is a workflow and recordkeeping tool. It is not a substitute for FAA-approved maintenance programs, qualified A&P/IA judgment, OEM manuals, or applicable regulations. All maintenance decisions, sign-offs, and airworthiness determinations remain the sole responsibility of the licensed mechanic and the certificate holder. You agree that Hangar Flow is not responsible for any maintenance error, oversight, or omission, and that the Service is used at your own discretion alongside — not in place of — established aviation maintenance practices.

8. Service availability

We work hard to keep the Service up and running, but we don't guarantee 100% uptime. Scheduled maintenance, third-party outages (Supabase, Stripe, Cloudflare, etc.), and unforeseen issues can cause occasional downtime. We will make a reasonable effort to notify active customers in advance of planned maintenance windows.

9. Termination

• You may cancel your subscription at any time. Cancellation stops future billing and ends access at the end of the current billing period.
• We may suspend or terminate your access if you violate these Terms, abuse the Service, or fail to pay.
• If we terminate your access for cause, prepaid subscription fees are non-refundable.
• After termination, your data is retained for 90 days in case you reactivate, then permanently deleted as described in our Privacy Policy.

10. Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE ERROR-FREE, UNINTERRUPTED, OR FREE OF HARMFUL COMPONENTS.

11. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, HANGAR FLOW SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, WHETHER INCURRED DIRECTLY OR INDIRECTLY, OR ANY LOSS OF DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, RESULTING FROM YOUR USE OF THE SERVICE.

OUR TOTAL LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED US DOLLARS ($100).

12. Indemnification

You agree to indemnify and hold Hangar Flow harmless from any claim, demand, liability, or expense (including reasonable attorneys' fees) arising out of (a) your use of the Service, (b) your violation of these Terms, or (c) your violation of any third-party right.

13. Changes to these Terms

We may revise these Terms from time to time. The "Last updated" date at the top will reflect any change. If a change is material, we will notify active customers by email at least 14 days before it takes effect. Continued use of the Service after the change means you accept the revised Terms.

14. Governing law

These Terms are governed by the laws of the State of Nevada, United States, without regard to its conflict-of-law provisions. Any dispute arising out of these Terms shall be resolved in the state or federal courts located in Clark County, Nevada.
