# Privacy Policy — AirBtu

**Effective date:** July 23, 2026

**Developer:** Nisit Sirimarnkit (ninenox)

**Contact:** nashnox15@gmail.com

This Privacy Policy explains how **AirBtu** ("the App") collects, uses, and

discloses information.

## 1. Information the App collects directly

AirBtu does **not require registration or sign-in** and does **not collect

personally identifiable information** (such as name, email, or phone number) on

our servers. Any values you enter to calculate air-conditioner size (BTU) are

processed on your device only.

## 2. Information collected by third-party advertising

AirBtu displays ads through **Google AdMob**, a service provided by Google.

To serve ads, AdMob may automatically collect and process certain data, such as:

- Device identifiers

- App usage and ad interaction data

- Approximate device and network information

Google's collection and use of data is governed by Google's policies:

- Google Privacy Policy: https://policies.google.com/privacy

- How Google uses information: https://policies.google.com/technologies/partner-sites

## 3. Tracking

AirBtu does **not track users across other apps or websites** and does not request

App Tracking Transparency (ATT) permission. Ads shown are non-personalized.

## 4. Permissions

AirBtu uses only the permissions it needs — internet and network-state access —

solely to load ads.

## 5. Children's Privacy

AirBtu is not specifically directed to children under 13, and we do not knowingly

collect data directly from children.

## 6. Data Security

Because AirBtu does not store personal data on our servers, data risk is limited

to third-party services (Google), which maintain their own security measures.

## 7. Changes to This Policy

We may update this policy from time to time; the latest effective date is shown above.
