Our Fundamental Privacy Guarantee: Zero Server Uploads
When you use Audio Cutter Online, your audio recordings and video files are NEVER transmitted across the internet to our servers or any third-party cloud infrastructure. All audio decoding, sample slicing, fade generation, and file exporting occurs 100% locally inside your device’s web browser (RAM). We do not—and cannot—listen to, store, copy, or analyze your media files.
1. Introduction
Welcome to Audio Cutter Online ("we", "our", or "us"), accessible via https://audiocutteronline.com. We believe user privacy is an undeniable fundamental right. This Privacy Policy outlines how our web application operates and details the complete absence of server-side data retention regarding your multimedia content.
By accessing or using Audio Cutter Online, you acknowledge and agree to the practices outlined in this policy.
2. Information We Do NOT Collect
Unlike conventional web services, our architectural model is zero-knowledge:
- Your Audio and Video Files: Audio files (MP3, WAV, AAC, M4A, FLAC, OGG, WMA) and video files (MP4, MOV, WebM) chosen via drag-and-drop or file pickers are read strictly into local client memory via the browser’s native
FileReaderandAudioContextAPIs. They are never transmitted over HTTP/HTTPS to our servers. - Biometric Audio Signatures: We do not perform voice recognition, speaker identification, or acoustic data mining.
- Personal Identity Data: We do not require registration, usernames, email addresses, phone numbers, or passwords to use the cutter.
- Payment Information: Our workstation is free; we do not collect credit cards, billing addresses, or banking information.
3. Information Automatically Processed
Like virtually all internet websites, when you load the static assets of our website, standard web server interaction occurs:
- Server Access Logs: Our hosting provider’s edge servers may log basic technical parameters including IP address, browser user-agent, operating system, referring URL, and timestamp. These logs are used exclusively for security audits, DDoS defense, and infrastructure stability.
- Anonymized Aggregated Metrics: We may analyze aggregate statistics (such as total page visits, popular screen resolutions, or general geographic country) to optimize website performance and responsiveness. These analytics do not contain personally identifiable information.
4. Local Storage and Cookies
We do not use intrusive cross-site tracking cookies or marketing pixels. We employ minimal HTML5 localStorage strictly for user experience preferences:
- Theme Preference: We store a single key (
theme: "light" | "dark") in your browser’s local storage so that your preferred visual theme persists between visits without screen flickering.
You can clear your browser storage or disable cookies at any time via your browser settings without impairing the core functionality of the audio trimmer.
5. Third-Party Services
To deliver rapid page loading globally and modern typography, we utilize reputable external service providers:
- Content Delivery Network (CDN): Distributes static HTML, CSS, and JavaScript files from edge caches closest to your physical location.
- Google Fonts: Delivers the Geist font family stylesheet to ensure clean typographical rendering.
None of these third parties ever receive or have access to any audio files opened in your browser.
6. Children's Privacy
Audio Cutter Online is safe for general audiences. We do not knowingly collect, request, or solicit any personal information from children under the age of 13 in compliance with the Children’s Online Privacy Protection Act (COPPA) and international child privacy regulations.
7. Data Security
Because audio processing is strictly isolated within the sandbox of your browser's local execution environment, the most effective security measure is inherent in our architecture: what is never uploaded can never be intercepted, breached, or leaked from a server.
8. Changes to this Privacy Policy
We may periodically update this Privacy Policy to reflect enhancements in technology, web standards, or regulatory guidelines. Any modifications will be posted directly to this URL with a revised effective date. Continued use of the website signifies your acceptance of any updates.
