Privacy Policy

Flight Display Pro for iPhone and Apple Watch

Effective date: September 29, 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: I do not collect any personal data, and your location and sensor readings stay on your device. If you choose to watch a video ad to earn free minutes, the ad is served by Google, and Google receives some device information as described below.

Summary

• The app has no user accounts and no analytics of my own.
• 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, and they are never given to the advertising service.
• The iPhone app offers rewarded video ads through Google AdMob. Ads are shown only when you ask for one. The app contacts Google for the first time when you first ask for an ad, and may then load the next ad ahead while the app stays open.
• Ads are non-personalized. The app does not ask for permission to track you and does not use the advertising identifier (IDFA).
• If you hold a pass or a subscription, you are not offered ads. The Apple Watch app shows no ads.
• Apart from ads and the App Store, the app makes no network connections and works fully offline.
• 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 free time has been used and how much has been earned from ads
• 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, with one exception: the free-time balance (two numbers, seconds used and seconds earned) is also kept in the device Keychain so that reinstalling the app does not restart the free preview. That entry stays on this device, is not synced to iCloud Keychain, and is removed when the device is erased. 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.

The Google advertising and consent SDKs keep their own data in the app's local storage, such as your consent choice. It is removed when you delete the app.

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 for navigation data, so it does not send anything about what you view or where you are over the network.

Advertising

Without a pass or subscription, you can add free minutes on iPhone by watching a video ad. Watching is always your choice; ads never appear on their own or over the flight display.

Ads are served by Google AdMob, using the Google Mobile Ads SDK and the Google User Messaging Platform SDK included in the iPhone app. When you ask for an ad, these SDKs connect to Google and may collect and process:

• Your IP address, from which Google may estimate your general location
• Device and app information, such as device model, operating system version, language, screen size and app version
• Identifiers that are not the advertising identifier, such as the identifier for vendors and identifiers the SDK creates for itself
• Your interactions with ads, such as views and taps
• Diagnostic information, such as crash and performance data of the SDK

Google uses this to deliver and measure ads, to limit how often an ad is shown, and to detect fraud and abuse. The app requests non-personalized ads only. It does not give Google your GPS position, your sensor readings, or anything about your purchases. I receive only aggregated reports from AdMob, such as the number of ads shown and the revenue, which do not identify you.

In the European Economic Area, the United Kingdom, Switzerland and other places where the law requires it, the app asks for your consent before the first ad is requested. You can change your choice at any time under Ad Privacy Choices on the app's store page.

Google's handling of this information is described in How Google uses information from sites or apps that use its services and in Google's Privacy Policy.

If you do not want any of this, do not ask for an ad. A pass or a subscription unlocks the display without ads.

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

I do not collect any of the following: contact information, location history, health or fitness data, financial information, contacts, photos, or browsing history. The app does not use the advertising identifier or track you across apps or websites. The information listed under Advertising goes to Google, not to me.

Because I hold no personal data, I have none to sell, disclose in response to requests, or delete on request. For data held by Google, use the controls Google provides at https://myadcenter.google.com and the links above.

Children

The app is not directed at children, and I collect 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.
