# Privacy Policy

**App:** Measure Ruler
**Publisher:** KTN Apps
**Effective date:** February 2026

KTN Apps ("we", "us") built Measure Ruler as a free utility app. This Privacy Policy explains how the app handles your information.

## 1. No Data Collection

Measure Ruler does **not** collect, store, transmit, or share any personal data. We have no accounts, no registration, no analytics, no advertising, and no third-party SDKs in the app.

## 2. Camera Use (AR Measure)

The AR measuring tools use your device camera **only** to display a live measurement overlay on screen. Camera frames are processed in real time on your device and are **never recorded, saved, or transmitted** anywhere.

## 3. Local-Only Storage

Your measurements, history, and sketches are stored **exclusively on your device** using Apple's SwiftData local storage. They are never uploaded to a server and never leave your device.

- You can delete individual measurements or sketches at any time from the app.
- Deleting the app removes all stored data permanently.

## 4. Device Features

The app uses built-in device sensors (gyroscope, accelerometer, magnetometer) for the level, protractor, and magnetometer tools. Sensor data is processed on-device in real time and is not stored or transmitted.

## 5. Children's Privacy

Because we collect no data, this app is safe for all ages and contains no advertising or external links that collect data.

## 6. Data Deletion / Your Rights

Since all data stays on your device, you have full control over it:

- Delete any measurement or sketch inside the app's History section.
- Uninstall the app to erase all data.

## 7. Changes to This Policy

If this policy changes, we will update this page and revise the "Effective date" above.
