Webcam?! What about Privacy?
Fair question. We use your webcam, so here are straight answers. We tell you exactly what happens to your data, and we show you how to verify it yourself.
Straight Answers on Privacy
Yes—iBlink uses your webcam.
The software needs to see your eyes to track blink patterns. That's fundamental to how it works. No camera access = no blink monitoring.
Your video never leaves your device.
All blink detection and analysis happens locally on your computer. The webcam feed is processed in real-time and immediately discarded—nothing is recorded, stored, or transmitted to our servers. Ever.
No biometric data is ever transmitted.
We do not collect facial landmarks, eye measurements, blink counts, or any biometric data. The AI model that tracks your blinks runs entirely on your machine and its outputs stay there too.
We collect only what is needed for your account and license.
To create an account and validate your license, we collect:
- Name & email address — provided by you when creating your account, used for login and license management.
- Device ID & hostname — recorded when you activate a license on a device. Used to enforce your activation limit and nothing else.
- OS version — logged at activation to help us provide version-compatible updates.
What we never collect: webcam footage, facial data, blink counts, health information, or any biometric data. That stays on your device.
iBlink contacts our servers for two things only.
- License validation — periodically confirming your license is still active and not revoked. No webcam data, no health data.
- Software update checks — checking whether a newer version of iBlink is available.
No analytics, no telemetry, no ad tracking, no user profiling.
We will never sell your data.
Your account information is used only to operate the service. We do not sell, rent, or share personal data with advertisers or data brokers—ever.
Payments are handled by Stripe—we never see your card.
All payment processing is handled by Stripe. We never receive or store credit card numbers, CVVs, or bank details. Stripe is a certified PCI Level 1 service provider.
Still Concerned? Block iBlink from the Internet.
You can take control and prevent iBlink from making any network connections at all.
Important: iBlink needs internet access every 7 days.
iBlink periodically re-validates your license to ensure it is still active and has not been revoked. This check happens at most once every 7 days. If you block iBlink from the internet, the app will continue to work during the grace period, but you will need to temporarily re-allow internet access every 7 days. Once the grace period expires without a successful re-validation, iBlink will prompt you to restore internet access before it can continue monitoring.
macOS's built-in firewall only manages incoming connections. To block outgoing connections from a specific app, the most reliable free tool is LuLu (by Objective-See, an open-source security researcher). Alternatively, you can use Radio Silence (paid, simpler UI).
