Need help with Cairn? You'll find answers below — and a way to reach out if you don't.
On macOS and iOS, tasks are stored locally on your device using the app's private container. They never leave your device unless you explicitly export them.
In the VS Code extension, tasks are saved to .vscode/cairn.json inside your open workspace folder. When no workspace is open, they fall back to VS Code's global storage.
No. Cairn is entirely offline and local. There are no accounts, no servers, and no cloud sync. Your data stays on your device.
The AI feature is available in the VS Code extension and requires a locally-running Ollama instance.
Install Ollama, pull the gpt-oss model (ollama pull gpt-oss), then click ✨ AI Parse in the Brain Dump overlay. Your text is sent only to the local Ollama process — never to any external server.
MIT (Most Important Task) is a priority level for tasks that absolutely must happen today. You can assign up to 1–3 MITs per day.
Focus Mode shows one task at a time so you're not distracted by the full list. It includes a built-in Pomodoro timer — 25 minutes of focused work followed by a 5-minute break — to help you work in sustainable intervals.
In the VS Code extension, tasks are stored as plain JSON in .vscode/cairn.json — you can copy, commit, or back up this file however you like.
On macOS and iOS, you can use standard system backups (iCloud Backup, Time Machine) to protect your data.
They're currently under Apple review. Check back here for updates.
The VS Code extension is free. The native apps are $0.99 — a one-time purchase with no subscriptions, no in-app purchases, and no recurring fees.
Cairn is a personal project. The best way to reach out is through the Q&A tab on the VS Code Marketplace page. This is monitored regularly and is the fastest path to a response.
For bug reports or feature requests related to the macOS, iOS, or other native apps, you can also use the same Q&A tab — just mention which platform you're on.
Cairn collects no personal data, uses no analytics, and never contacts external servers. See the Privacy Policy for full details.
