Data on disk¶

Cue stores everything locally. There is no server, no sync, no account.

Where things live¶

Platform	Data root
macOS	`~/Library/Application Support/Cue/`
Windows	`%LOCALAPPDATA%\Cue\`

There's a second per-platform location used only for the streaming pipeline, because GStreamer's filesink doesn't tolerate spaces in paths:

Platform	Streaming root
macOS	`~/Library/Caches/Cue/`
Windows	(same as data root)

What's in each location¶

Data root¶

Path	Purpose
`config.json`	API key, streaming toggle, digest backend, custom block lists, browser auth state. Written atomically.
`cue.db`	SQLite — `sessions` (one row per hotkey invocation), `digests` (rolling activity-narrative time series). `created_at` is local-time ISO with timezone offset (e.g. `2026-05-06T11:21:41.690486+09:00`) — the digest history UI shows wall-clock time the user actually saw.
`digest.md`	The latest activity summary (cloud Haiku or local Gemma 4 output, post-PII-scrub).
`memory.md`	The long-term user profile maintained by Opus from recent digests.
`browser_auth.json`	Per-browser authorization tristate (`authorized` / `denied` / `unknown`).
`cue.log`	Rolling app log (PII-scrubbed).
`privacy.log`	Pause-event audit log.
`models/`	Local Gemma 4 GGUF + mmproj weights, only present if on-device backend was used. Multi-GB.

Streaming root¶

Only populated when Enable Streaming is on.

Path	Purpose
`stream/chunk_<ts>.mkv`	30-second video chunks (H.265, hardware-encoded).
`stream/chunk_<ts>.mcap`	Structured event log per chunk (clicks / keys / window changes).
`keyframes/keyframe_<ts>.jpg`	Pruner output: small JPEGs of moments where something visually changed or a real input event happened.

Old chunks and keyframes are auto-evicted when they fall outside the retention window (default 15 minutes, configurable via the streaming config keys).

Wiping data¶

The cleanest way: Preferences → Data → Clear Data.

It removes the SQLite database, screenshots, keyframes, streaming chunks, memory.md, and the current digest.md. The API key in config.json is preserved.

Manual wipe (when Cue isn't running):

# macOS
rm -rf "$HOME/Library/Application Support/Cue" \
       "$HOME/Library/Caches/Cue"

# Windows (PowerShell)
Remove-Item -Recurse -Force "$env:LOCALAPPDATA\Cue"

This also removes the API key. Re-launching Cue will prompt for it again.

Privacy posture summary¶

Nothing is uploaded beyond Anthropic API requests for the digest, memory, and suggestion calls. Each request includes a prompt that has been PII-scrubbed (Presidio + Cue-specific recognizers) before transmission.
Image bytes are never written to SQLite or to any log file. Only the prompt text is logged, and only after scrubbing.
The privacy-pause purge cascade retroactively deletes in-flight artifacts when pause activates. See Privacy controls.
