Privacy

Last updated: October 2026

The short version

Your journal lives on your devices. If you turn on Cloud, a copy lives on our server so your devices and your AI can reach it. We don't run analytics, show ads, or sell anything about you.

On your devices

The apps keep your journal in a SQLite file on each device: to-dos, food, training, notes and settings. If you add your own AI key, it's kept in the system's secure storage (the Keychain on Apple devices), never in the journal file.

Without an account, nothing leaves your device except the AI requests you make (see below).

If you use Cloud

When you sign in, we store:

• Your account: your email address and the account ID that Apple or Google gives us when you sign in.
• A copy of your journal, so it syncs between your devices and your AI can read and write it.
• Your devices and connections: a token for each signed-in device and each connected AI app, with its name and when it was last used.
• Counters: how many requests you made this minute (to stop abuse) and how many AI requests you made today (for the daily limit).

Data is encrypted in transit, and stored on Cloudflare.

AI

• Your own key or a local model: requests go straight from your device to the provider you chose (for example Anthropic or OpenAI), or stay on your computer with a local model. They don't pass through us. That provider's privacy policy applies.
• Cloud + AI: the text or meal photo you send goes through our server to Anthropic's Claude, which sends back its guess. We don't log what was asked or answered. Anthropic handles it under its commercial terms, which don't allow it to train on your data.

Connected AI apps

When you connect ChatGPT, Claude or another agent, you approve it on a consent page. It can then read your journal, and write to it if you allowed that. What it does with what it reads is covered by that app's own privacy policy. You can disconnect any of them at any time in the app's Settings.

Who else is involved

• Cloudflare: hosts our server, this website and your synced journal.
• Apple and Google: sign-in, app distribution and, for paid plans, purchases. We never see your card.
• Anthropic: the AI in Cloud + AI.

Your control

• Export everything as CSV or Markdown at any time, from the app or the CLI.
• Sign out any device, or disconnect any AI app, in Settings.
• Delete your account in Settings. That removes your journal, devices and connections from our server right away. What's on your devices stays until you delete the app.
