Frownie runs entirely on your Mac. It watches your webcam locally to notice when you frown and nudge you to relax. Your video, images, and facial data never leave your device — there is nothing to upload, and no server to send it to.
What we collect
Nothing from the app itself. Frownie has no account, no sign-in, and no analytics that identify you. We do not collect your contacts, location, or usage patterns, and we never see anything your camera sees. If you buy a license, our payment provider collects the name, email and billing details needed to take the payment and meet tax law — see “Payments and licensing” below.
Your camera and face
Camera frames are analyzed on your device using an on-device model (Apple’s Vision / Google’s MediaPipe) to measure brow tension. Frames are never recorded, saved, or transmitted. The green camera light turns off whenever there’s no one to watch — screen locked, Mac asleep, or you’ve stepped away.
What’s stored on your Mac
Your settings and per-day frown counts are saved in a local file (settings.json) on your computer. This never leaves your Mac, and deleting the app removes it.
Network connections
The app makes exactly two kinds of network request, and neither one carries anything your camera saw. It checks GitHub for the latest release so it can offer updates. And when you activate a license key, it sends that key once to our payment provider to confirm it is valid, then re-checks it at most once a month; if that check fails or you are offline, your license keeps working. Choosing “Book Botox near me” from an alert simply opens a web search in your browser.
Payments and licensing
Purchases are handled by Polar, which acts as the merchant of record and is the seller on your receipt. Polar collects your email, billing address and payment details in order to charge you and to account for sales tax and VAT; we never see your card details. Your license key is tied to your email address so you can recover it. Polar processes this under its own privacy policy.
Third parties
No video, images or facial data are shared with anyone, because they never leave your device. Downloads and update checks are served by GitHub, and payments and license keys by Polar, each under their own privacy terms.
Not medical advice
Frownie is a lighthearted habit tracker for reducing frowning. It is not a medical device and does not provide medical advice.
Changes
If this policy changes, we’ll update the date above. Continued use of the app means you accept the current version.
