Privacy
On-device and private.
EyesRhythm is meant to sit next to your work, not on someone else’s server. This page states that plainly.
What never leaves the machine
No internet is required for normal use. There is no account, no login, no cloud, and no analytics. Camera frames are processed on this computer only, in real time. Video is not recorded for upload, not stored as a film of your face, and not shared.
What may be kept locally
What is kept, if anything, is yours: today’s blink and screen-time totals, preferences, and optional on-device history for your own reports. That data stays in a folder on the computer and resets or remains there according to the app. It is not sent to us or to anyone else.
On macOS and Windows the local folder is typically under your home
directory as .eyerhythm_blinkcounter.
Sharing the app
When a copy is issued, you can share that Mac app or Windows zip. The recipient runs it locally. There is no “phone home.” This website does not host installers, and copies are not offered for download until payment and licensing are ready.
This website
This site is a static page. It does not set cookies, does not load analytics, and does not call third-party scripts. A license reservation is stored only in your browser until payment is connected.
Not a medical device
EyesRhythm is a wellness companion. It has not been cleared or approved by the FDA or any other regulator. It is not intended to diagnose, treat, cure, or prevent disease. ORI is a cadence score you can act on — not a diagnosis. If you have an ocular surface disorder, a change in vision, or persistent discomfort, consult a licensed eye-care professional.
