Privacy Policy
This Privacy Policy explains what S4 Integrations LLC, operating as HangarGuard ("HangarGuard," "we," "us"), 791 Case Karsten Dr Unit 3, Zeeland, MI 49464, collects when you use the HangarGuard platform, website, mobile applications, and text messaging program (the "Service"), how we use it, and the choices you have.
1. Information we collect
Account information: your name, email address, mobile phone number, the FBO or aircraft you are associated with, and your role (FBO staff, aircraft owner, or pilot).
Aircraft and service records: aircraft registration (tail) numbers, aircraft type, photos and voice notes captured by FBO staff during arrival, movement, and release, service notes, the FBO location where service occurred, and timestamps. Photos may incidentally include people or surroundings on the ramp.
Messages: the content of text messages you send to and receive from HangarGuard, including replies exchanged with FBO staff, and the delivery status of those messages.
Consent records: when you opt in to text messages we record your mobile number, the date and time, the wording you agreed to, the page you used, and your device's IP address and browser or app information, so we can prove consent was given.
Technical information: device type, operating system, app version, IP address, and usage logs.
Crash reports and usage events: the HangarGuard web console and apps send crash and error reports to our error-monitoring provider (Sentry) and usage events to our product-analytics provider (PostHog). These reports do not include your name, email address, phone number, or the contents of your messages. When an error report includes a replay of the screen, all text is masked.
2. How we use it
We use this information to create and secure your account, send login codes, create and share aircraft custody records, notify you about aircraft you own, fly, or service, relay messages between you and FBO staff, provide support, keep records the FBO is required to keep, improve the Service, and comply with law.
3. Text message opt-in data (SMS privacy)
Your mobile number and text-message opt-in information are used only to send the HangarGuard notifications you agreed to and to keep a record of your consent. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. All other categories of sharing described in this policy exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties. Your mobile number is disclosed only to the service provider that delivers messages on our behalf, solely to deliver those messages, and that provider may not use it for any other purpose. We do not sell or share your SMS opt-in data or personal information with third parties for marketing purposes.
You can stop text messages at any time by replying STOP to any message or by turning off text notifications in Profile → Notifications. Reply HELP for help, or contact swolters@s4integrations.com or (616) 288-2665. Message frequency varies. Message and data rates may apply. The program terms are in section 3 of our Terms of Service.
4. Who we share information with
The FBO and aircraft parties: records about an aircraft are visible to the FBO that created them and to the owners and pilots associated with that aircraft. FBO staff can see the name and mobile number of customers they are messaging.
Service providers: companies that host our data, deliver text messages and email, and provide app infrastructure, under contracts that limit their use of your information to providing those services.
Legal: when required by law, legal process, or to protect the rights, safety, or property of HangarGuard, an FBO, or others, including in connection with an aircraft damage claim where the record is relevant.
We do not sell personal information. The sharing described in this section never includes your text messaging opt-in data or consent, which is covered by section 3.
5. How long we keep it
Account information is kept while your account is active and for a reasonable period afterward. Aircraft custody records are kept according to the FBO's retention settings and applicable law, because they may be needed to resolve claims long after service. Text-message consent and opt-out records are kept for at least four years after your last message, even if you delete your account, so that we can demonstrate compliance.
6. Your choices
You can update your account information and notification settings in the app. You can opt out of text messages by replying STOP. You can request a copy of your information or ask us to delete your account by contacting us; we will honor the request except where we must keep records for the reasons in section 5.
7. Security
We use encryption in transit and at rest, access controls, and logging to protect your information. No system is perfectly secure; if we learn of a breach affecting your information we will notify you as required by law.
8. Children
The Service is for adults working with or operating aircraft and is not directed to anyone under 18. We do not knowingly collect information from children.
9. Changes and contact
We may update this policy and will post the new version here with a new effective date. Questions: swolters@s4integrations.com, (616) 288-2665, or S4 Integrations LLC, 791 Case Karsten Dr Unit 3, Zeeland, MI 49464.
