While a focus block is running, the AI captures a downscaled, compressed screenshot of your main display at regular intervals along with a short text snippet (up to 1,200 characters of visible DOM text in browsers, or window titles on native apps). Outside of an active block, nothing is captured.
Where the data goes
The screenshot and text snippet are sent to FocusDragon AI for a single classification call. Under the hood, FocusDragon AI routes through third-party model providers with automatic failover between them (so a brief outage on one provider doesn't break your block). Nothing is written to disk on your Mac, and FocusDragon never stores the screenshot on its own servers — our backend treats it as a pass-through and discards it in the same function call.
What each provider does with the input
- The third-party model providers FocusDragon AI routes through all operate under the same contract: API inputs are NOT used to train their models. Inputs are retained for up to 30 days for abuse and safety monitoring, then permanently deleted. The specific providers may rotate over time as we improve the classifier — the no-training, short-retention guarantee is the load-bearing privacy contract, not the provider name.
- FocusDragon's servers: never store the screenshot or text. The only thing we persist is a monthly per-user call count (a single integer) for quota enforcement.
What's excluded from text capture (hard-coded)
- Banking, payments, and brokerage sites
- Email providers
- Identity / authentication / password manager sites
- Healthcare sites
- Incognito / private browsing tabs (all browsers)
On those sites, only the URL and tab title flow alongside the screenshot. The text-exclusion list is baked into the browser extension; you can't accidentally turn it off.
On a paid AI Focus plan, the payload transits our server so we can authenticate your subscription and increment usage, then routes through FocusDragon AI's third-party model providers — we don't log or store the content. With the BYOK add-on, the payload goes directly from your Mac to the provider you've configured (Anthropic Claude) and our servers see nothing.
