echo·11 is a sound-based wellness app for relaxation and focus, currently in a free founding beta. For any question — a bug, a billing worry (there is none: the beta is free), your data, or anything else — reach out and a human will answer.
Email shirasarid@gmail.com with a short description of the issue. If it's a bug, mentioning your device and browser helps us fix it faster.
Common questions
The audio doesn't start
Browsers only start audio after a tap. Open a frequency and tap play; if you still hear nothing, check your device isn't in silent mode and the volume is up.
Binaural protocols sound like a plain tone
Binaural frequencies need stereo headphones — each ear receives a slightly different tone, and the "beat" only appears when both channels are separated. Speakers or a single earbud won't produce it.
Where is my data stored?
During the beta, everything — history, streaks, favorites — lives only in your browser's storage on your own device. Nothing is uploaded. Details in our Privacy Policy.
How do I delete my data?
In the app: Profile → Delete my account. This permanently clears your listening history, streaks, saved frequencies, and preferences from the device. Clearing your browser's site data does the same.
Is echo a medical product?
No. echo.|| is a wellness and entertainment tool — it does not diagnose, treat, cure, or prevent any condition. Please read the safe-use & medical disclaimer, especially if you have epilepsy or a seizure disorder, a pacemaker, or are pregnant.
Never listen while driving or operating machinery. Keep the volume moderate, and stop immediately if you feel discomfort, dizziness, or unease. In a medical or mental-health emergency, call your local emergency number — echo.|| does not provide emergency services.
