Privacy Policy of Online Alarma

1. Zero Personal Data Collection

Online Alarma does not request, collect, or store any personal information. You do not need to register, create an account, provide an email address, or provide payment details to use any of our features.

• No registration or login required
• No email, name, or phone number requested
• Free and unlimited access to 100% of our tools

2. Local Storage on Your Device (LocalStorage)

All your customized preferences—such as scheduled alarms, volume levels, 12h/24h format preferences, dark mode preferences, and world clock cities—are saved exclusively in your browser's local storage (LocalStorage / IndexedDB).

This data never leaves your device. You can erase all stored preferences at any moment by clearing your browser cache or site data.

3. Local Audio Synthesis & Sound Safety

Our alarm sounds and chimes are synthesized directly in your browser using the HTML5 Web Audio API and local sound assets. We do not access your microphone, record audio, or transmit any media to external servers.

4. Progressive Web App (PWA) & Offline Mode

Online Alarma is engineered as a Progressive Web App (PWA). Once loaded, essential files are safely cached on your machine so the alarm clock, stopwatch, and calculators work reliably even without an internet connection.

5. Technical Server Logs & Cookies

We do not deploy advertising profiling cookies or third-party behavioral trackers.

Like most websites, our hosting servers may automatically log basic HTTP connection metadata (such as anonymized IP addresses, browser user-agent, and request timestamp) solely for DDoS mitigation, infrastructure health, and performance monitoring.
