Privacy Policy
Last updated: October 2026
Water Eject respects your privacy. All acoustic sound generation happens locally in your browser.
1. 100% Local Browser Audio Synthesis
Water Eject generates 165Hz and 150ā350Hz sound waves directly inside your device's browser using the standard Web Audio API. We never request microphone access, never record audio, and never upload any device audio to any server.
2. Privacy-First Analytics
We use self-hosted Umami analytics on our production domain (waterej.online) to measure aggregate tool usage (such as starting auto or manual mode) without cross-site tracking cookies or personal identifiers. Non-attribution URL query parameters are automatically stripped before transmission.
3. Cookies & Google AdSense (Consent-Gated)
We only load Google AdSense scripts after you explicitly click Accept on our cookie banner. If you choose Essential Only, no advertising scripts or third-party ad cookies are loaded. When accepted, Google may use cookies to serve ads based on prior visits; you can manage ad personalization at https://adssettings.google.com.
4. PWA Cache & Local Storage
To allow Water Eject to work offline in emergencies, our Service Worker caches static app assets on your device, and localStorage stores your language and cookie consent preferences. You can clear these anytime via your browser settings.
5. Your Rights (GDPR & CCPA)
Depending on your jurisdiction, you have the right to withdraw cookie consent at any time by clearing site storage, opt out of personalized advertising, and request information about data processing.
