Privacy Policy - Drift Catcher | Whatever Works Studio

Drift Catcher is built around one promise: your focus data is yours, and it stays on your Mac. This policy explains exactly what that means.

The short version

Drift Catcher collects no personal data and sends no analytics or telemetry to us or anyone else.
All AI runs on your device. Screen content never leaves your Mac.
The app goes online for one thing only: an optional download of the Gemma 3 AI model, which happens only if you choose it. That download sends no information about you.

What the app accesses, and why

Active window title (via Screen Recording permission). To tell whether you're on task, Drift Catcher reads the name of the app you're using and the title of its window (for example, a browser tab's page title). It does not capture, record, store, or transmit any screen images or content, and it never reads the contents of your messages or documents. The title is used in the moment, by the on-device AI or a built-in list of well-known distractions, to classify "on-topic vs. off-topic". It is stored only in your local session history on your Mac.
Keystrokes. Never read.
Notifications (optional). Used only to show a "Session complete" notification when a focus session finishes on its own.

What is stored, and where

Your sessions, drift events, and AI reflections are stored locally on your Mac using Apple's on-device database (SwiftData). They are never uploaded.
The Insights screen is computed entirely from this local data. You can export a snapshot (JSON or Markdown) manually if you choose to — the app never sends it anywhere on its own.
You control retention in Settings (keep 7 days, 30 days, or forever) and can delete all data at any time.

The only network connection: the optional model download

If Apple Intelligence is available and turned on, Drift Catcher uses Apple's on-device model and needs no download. Otherwise, on any supported macOS version, you can choose to download Google's open-weights language model Gemma 3 (about 3 GB). The download starts only when you click Download (about 3 GB) during onboarding or in Settings ▸ On-device AI. Nothing is downloaded automatically.

The files come from Hugging Face and are saved in the app's private container on your Mac; during the download the app also fetches the model's file list. These requests fetch model files to your Mac and include no personal data, account, or usage information. Once the download is complete, Gemma loads from your Mac without going online, and all inference is local. If the model files are later removed (for example, when macOS frees up space), nothing is downloaded again until you click Download again.

Gemma is provided under and subject to the Gemma Terms of Use.

No tracking, no third parties

No advertising, no analytics SDKs, no crash-reporting services, no trackers.
No data is shared with third parties because no data is collected.

Children's privacy

Drift Catcher does not collect data from anyone, including children. It is rated 4+.
