Privacy Policy

Flight Display Pro for Android and Wear OS

Effective date: October 4, 2026

Flight Display Pro ("the app") is published by Tanut Apiwong ("I", "me"). This policy covers the app on Android phones and Wear OS watches. It 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. Apart from that, the only thing that leaves the phone app is one value, the time your access ends, which goes to your own watch.

Summary

• The app has no user accounts and no analytics of my own. It includes Google's software for purchases, for talking to your watch, and for the optional video ads.
• 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 phone 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 use the advertising ID, and it does not use Android's Privacy Sandbox ad features (interest topics or attribution).
• If you hold a pass or a subscription, you are not offered ads. The Wear OS app shows no ads.
• Apart from ads and Google Play, the app makes no network connections and works fully offline.
• Purchases are handled entirely by Google Play. 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 the device's GPS receiver, and only while the app is in front. It does not use Wi-Fi or cell positioning. It uses location to show ground speed, GPS altitude, track and GPS status, to work out magnetic variation, and to position your aircraft symbol on the navigation display. The app needs precise location; approximate location alone is of no use to it.

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 does not read your location in the background.

You can decline location access when the app asks for it, or revoke it at any time in the app's permissions in your device's Settings. The instruments that depend on GPS will then show GPS OFF.

Motion and barometer

The app reads the motion sensors and the barometer to show attitude, heading, barometric altitude, and vertical speed. Android does not ask for permission for these sensors, so there is no permission to decline. The app reads them only while it is in front.

This data is processed in memory on your device and is not stored or transmitted.

Whether you are online

The app checks whether your device is online. It does this without connecting to anything. It needs to know to judge whether what Google Play says about your subscription is up to date, and to tell you when an ad cannot be loaded.

Settings stored on your device

The app saves a small number of items 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 the 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
• A record of each pass you bought. Google Play forgets a pass once it is used up, so the app keeps the purchase record itself
• A note of which Pro plan you chose

The record of a pass is the receipt Google Play gave the app: what you bought, when, and Google's order number. It does not contain your name, email address or payment details. None of the other items identify you. None of these items leave your device through the app, with one exception: the phone sends the expiry time to your watch, as described under Purchases and subscriptions. They are removed when you delete the app. The app opts out of Android's backup altogether, so they are not copied into a device backup. Because of that, deleting and reinstalling the app starts a new free preview.

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

Because the record of a pass is kept only on the device, a pass does not move to a new phone or survive deleting the app. A Pro subscription does, through Google Play.

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 the phone 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 phone 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, Android version, language, screen size and app version
• Identifiers that are not the advertising ID, such as the app set ID 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 and has removed its access to the advertising ID, so Google sees only zeros in its place. 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

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

The app asks Google Play on your device what you have bought, and it receives only the product purchased, when it was bought and whether it renews.

Purchases are made only on the phone. To unlock your watch, the phone sends it one value: the time your access ends. Google's software on your phone and watch delivers it, over Bluetooth when the two are connected, and otherwise over the internet through Google, encrypted so that only your phone and watch can read it. It never passes through any server of mine, and nothing else is sent. Pressing REFRESH on the watch asks the phone to send that value again.

Google provides me with aggregated sales and install reports that do not identify individual customers. If you have chosen to share usage and diagnostics data with Google in your device settings, Google may also provide me with aggregated, anonymized crash and performance statistics.

Google's handling of your information is governed by Google'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 ID 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 Google Play listing.
