Effective: September 6, 2026
Last updated: September 6, 2026

AC Remote Universal is provided by Professional AI Laboratory (“we,” “us,” or “our”). This policy explains how the Android app handles information when you use it to control air conditioners over infrared or an optional network bridge.

In short: the app has no accounts and collects no personal identifiers. Your air-conditioner profiles, rooms, and presets stay on your device. The app collects anonymous usage analytics that you can switch off in the app, and it shows advertising supplied by Google AdMob.

1. Information stored on your device

The following is kept locally and is never transmitted to us:

Android cloud backup is disabled for this app, so the operating system does not copy this data off the device. Uninstalling the app removes all of it.

2. Usage analytics

We use Google Analytics for Firebase to understand which parts of the app are used and where setup fails. Analytics is enabled by default and can be turned off at any time in Settings → Privacy → Usage analytics. The choice is saved on your device and applied on every launch.

The events recorded are:

These events contain no free text, no room names, no bridge address, and no bridge token. No user ID is assigned. Firebase Analytics advertising-identifier collection and ad-personalization signals are disabled for analytics, and automatic screen reporting is off.

Firebase processes this data on Google infrastructure. See Firebase privacy information and the Google Privacy Policy.

3. Advertising

The app is free and is funded by advertising served through Google AdMob. It shows banner, interstitial, and app-open ads, and an optional rewarded ad that removes ads for two hours.

The AdMob SDK accesses your device advertising identifier and may collect device and ad-interaction information in order to serve, measure, and limit the frequency of ads. This is separate from the app analytics setting: turning off usage analytics does not stop AdMob from accessing the advertising identifier.

You can reset or delete your advertising identifier, and opt out of ad personalization, in Android Settings → Privacy → Ads. See how Google uses data from apps that use its services.

4. Permissions and network behavior

The app requests two permissions: Internet, used to load ads, send analytics, and reach a bridge you configure; and Transmit infrared, used to send commands through your phone infrared emitter where one is present.

Outgoing connections are limited to Google advertising and analytics endpoints and, if you configure one, the bridge address you entered. Bridge connections must use HTTPS, and unencrypted traffic is blocked by the app. Infrared control itself works with no internet connection at all.

5. What the app does not collect

There are no accounts and no sign-in. The app does not ask for your name, email address, phone number, or postal address. It does not access location, contacts, camera, microphone, photos, or files, and it contains no crash-reporting SDK. It does not sell personal information.

6. Your choices and rights

To request deletion of analytics data associated with your device, email vunguyen.dev.0306@gmail.com with the approximate dates and country of use so the request can be located. We respond within 30 days.

7. Retention, transfers, and security

On-device data remains on your device until you remove it in the app or uninstall the app. Analytics events are retained by Google for the period configured on our Firebase project and are not linked to an identified person. Analytics and advertising data may be processed on servers outside your country, including in the United States, by Google under its own safeguards.

We use reasonable safeguards, but no device, network, or transmission system is completely secure. Keep your device, your local network, and any bridge hardware secure.

8. Children

The app is not directed at children, and we do not knowingly collect data from children under 13. If you believe a child has provided information through the app, contact us and we will act on it.

9. Changes and contact

We may update this policy as the app changes. The revised policy will be posted here with an updated date, and material changes to what is collected will be noted in the app release notes.
