1. Information We Collect

Hello Sounds is a standard web application. We do not require users to register or provide personal information to use our service. However, like most websites, we may collect non-personally-identifying information of the sort that web browsers and servers typically make available, such as the browser type, language preference, referring site, and the date and time of each visitor request.

2. Cookies and Tracking Technologies

Hello Sounds uses cookies and similar technologies to enhance your browsing experience. Cookies are small data files stored on your device. We use the following types of cookies:

• Essential Cookies: Required for basic site functionality, such as remembering your language preference and theme setting (stored in localStorage).
• Analytics Cookies: We use Google Analytics (GA4) to understand how visitors interact with our site. This data helps us improve user experience. Google Analytics collects anonymized information such as page views, session duration, and device type.
• Advertising Cookies: Google AdSense uses cookies to serve relevant advertisements. These cookies enable Google and its partners to serve ads based on your visits to this site and other sites on the Internet.

You can manage your cookie preferences through your browser settings. You may also opt out of personalized advertising by visiting Google Ads Settings or Digital Advertising Alliance.

3. Google AdSense

This site uses Google AdSense to serve advertisements. Google, as a third-party vendor, uses the DART cookie and other tracking technologies to serve ads based on your prior visits to this website and other websites. You can opt out of the use of the DART cookie by visiting the Google ad and content network privacy policy.

4. Third-Party Services

We use the following third-party services:

5. Children's Privacy

Hello Sounds is designed to be a safe educational platform for users of all ages, including children. We do not knowingly collect personal information from children under the age of 13. Our service does not require account creation, and we do not collect names, email addresses, or any other personally identifiable information from our users during normal use.

6. Data Security

We value your trust in providing us your information. We implement commercially reasonable security measures to protect data. However, no method of transmission over the internet or method of electronic storage is 100% secure, and we cannot guarantee its absolute security.

7. Your Rights (GDPR / CCPA)

Depending on your jurisdiction, you may have rights regarding your personal data:

• EU/EEA Residents (GDPR): You have the right to access, rectify, erase, restrict processing, and port your personal data. You also have the right to withdraw consent at any time.
• California Residents (CCPA): You have the right to know what personal information is collected, request deletion, and opt out of the sale of personal information. Hello Sounds does not sell personal information.
• All Users: Since Hello Sounds does not collect personal data beyond cookies and localStorage, you can exercise most rights by clearing your browser cookies and localStorage.
