+<h1>Privacy Policy - Decibel App</h1>
+<p>Welcome to our Decibel App. This application uses the microphone permission to measure sound decibels accurately. We value your privacy and have implemented measures to protect your personal information.</p>
+
+<h2>Purpose of Microphone Permission</h2>
+<p>To provide accurate measurements of sound decibels, our app requires access to your device's microphone. The use of the microphone permission is limited to the functionality of sound decibel detection and will not be used for any other purpose.</p>
+
+<h2>How We Use Microphone Permission</h2>
+<p>The microphone permission is only activated when you use the decibel detection feature. It is used to capture ambient sound data, perform analysis, and provide corresponding decibel measurement results. We do not save, store, or share the recorded audio data. Audio data is processed in real-time locally on your device and is not recorded or transmitted to external servers.</p>
+
+<h2>Data Security</h2>
+<p>We have implemented measures to ensure the security of your audio data:</p>
+<ul>
+    <li><strong>Local Processing:</strong> Audio data is processed in real-time locally on your device and is not transmitted to any external servers.</li>
+    <li><strong>Encryption:</strong> All communications related to audio data use secure encryption protocols to ensure the security of data transmission.</li>
+</ul>
+
+<h2>Consent Authorization</h2>
+<p>Upon the first launch of the app, we will request microphone permission. Please ensure that you grant this permission to enable the proper functioning of the decibel detection feature. You can revoke the authorization for microphone permission at any time through your device's settings.</p>
+
+<h2>Data Sharing</h2>
+<p>We commit not to share your audio data with any third parties, and it will not be used for advertising purposes. Your privacy is our top priority.</p>
+
+<h2>Privacy Policy Updates</h2>
+<p>We may periodically update our privacy policy to reflect changes in the application or regulations. You will receive timely notifications within the app and have the choice to accept or decline updates.</p>
+
+<p>If you have any concerns or questions regarding privacy or security, feel free to contact us. We are dedicated to providing you with a secure and reliable service.</p>
+
+<p class="highlight">Thank you for choosing our Decibel App. We are committed to offering you a safe and trustworthy service.</p>
