Privacy Policy

Flight Display Pro for iPhone and Apple Watch

Effective date: September 20, 2026

Flight Display Pro ("the app") is published by Tanut Apiwong ("I", "me"). This policy explains how the app uses your information. The short version: the app does not collect, transmit, or share any personal data. Everything it reads from your device stays on your device.

Summary

• The app has no user accounts, analytics, advertising, or third-party SDKs.
• The app makes no network connections. It works fully offline.
• The app uses sensor and location readings only to draw the flight display in real time. It does not record, log, or send them anywhere.
• Purchases are handled entirely by Apple. I never see your payment details or your identity.

Information the app uses on your device

Location

With your permission, the app reads location data from Core Location while the app is in use. It uses this to show ground speed, GPS altitude, track, heading and GPS status, and to position your aircraft symbol on the navigation display.

Location data is processed in memory on your device as it arrives. The app does not store a history of your position, record flights or tracks, or transmit your location to me or anyone else. The app requests "When In Use" access only and does not track your location in the background.

You can decline or revoke location access at any time in Settings, Privacy & Security, Location Services. The instruments that depend on GPS will then show as unavailable.

Motion and barometer

With your permission, the app reads the motion sensors and the barometer through Core Motion. It uses this to show attitude, heading, barometric altitude, and vertical speed.

This data is processed in memory on your device and is not stored or transmitted. You can decline or revoke access at any time in Settings > Privacy & Security > Motion & Fitness. The instruments that depend on these sensors will then show as unavailable.

Settings stored on your device

The app saves a small number of preferences in its local storage on your device so that it behaves the same way the next time you open it:

• Level calibration (the reference orientation you set, and the mirror option)
• Navigation display range and overlay choices
• The last page shown on Apple Watch
• Which version of the safety disclaimer you have acknowledged
• How much of the free preview time has been used
• The expiry time of your current pass or subscription, cached so the app can unlock without a connection

None of these settings identify you, and none of them leave your device through the app. They are removed when you delete the app. If you have device backups turned on, Apple may include app data in your encrypted iCloud or computer backup under your own Apple Account; I have no access to those backups.

Navigation data

Airports, navaids, airspace and other navigation data come from a database bundled inside the app. Lookups run on your device. The app does not query any online service, so it does not send anything about what you view or where you are over the network.

Purchases and subscriptions

Apple sells passes and subscriptions through its In-App Purchase system. Apple processes the payment and holds your payment details, billing information, and Apple Account. I do not receive your name, email address, payment method, or any other identifying information.

The app asks the App Store on your device whether you have an active purchase, and it receives only the product purchased and its dates. Your Apple Watch unlocks through the same Apple Account, not through any of my servers.

Apple provides me with aggregated sales and download reports that do not identify individual customers. If you have chosen to share analytics with app developers in your device settings, Apple may also provide me with aggregated, anonymized crash and usage statistics. You can change that choice in Settings, Privacy & Security, Analytics & Improvements.

Apple's handling of your information is governed by Apple's Privacy Policy.

Information I do not collect

The app does not collect any of the following: contact information, location history, identifiers, usage data, diagnostics, health or fitness data, financial information, contacts, photos, or browsing history. The app does not use advertising identifiers or track you across apps or websites.

Because I collect no personal data, I have none to sell, share, disclose in response to requests, or delete on request.

Children

The app is not directed at children and collects no personal data from anyone, including children under 13.

If you contact me

If you email me for support, I receive your email address and whatever you choose to include in the message. I use it only to reply to you and do not add it to any mailing list or share it with anyone.

Changes to this policy

If the app's behavior changes in a way that affects your privacy, I will update this policy and change the effective date above before the change ships. The current version is always available at the address linked from the app's store page and from its App Store listing.
