Get Optic
Install it on the family PC, create one parent account, and pair them with a six-digit code. Free, no card, no ads.
You're on another device. Optic installs on your child's Windows PC — open this page on that computer, or send yourself the link.
One platform, done properly
Windows today
Optic is a Windows application: a system service that enforces the rules plus a small companion app. Other platforms are not available — any page suggesting otherwise is out of date.
SHA-256 of the published installer: EAB26780C42D606B64DC520DD28CD49AA4D255A27EC3956B8E1734BDD6200914
Before you install
System requirements
| Platform | Minimum OS | Disk | Notes |
|---|---|---|---|
| Windows | Windows 10 (21H2), 64-bit | 180 MB | Administrator rights needed for the first install only. The WebView2 runtime (required to display the monitor) installs automatically — no separate download. No other runtimes needed. |
Verify your download
Compare the installer's SHA-256 against the value shown above before running anything you didn't get from us directly. Until the installer is code-signed, Windows SmartScreen will ask you to confirm — that warning goes away once signed builds ship.
Updating
There is no automatic updater yet: when a new build is published here, download it and run it over the old install. Your PIN, rules and history carry over.
Uninstalling
Removal needs two things at once: a Windows administrator and your Optic parent PIN. Just one of them is not enough, by design.
