Where is my data stored?
Everything stays in your browser's local storage — on your device, never on a server. Nothing is transmitted anywhere. You can read more about how this works in our local-first explainer.
What does 'your data never leaves your device' actually mean?
It means there is no server, no cloud sync, and no account. The app runs entirely in your browser using the browser's built-in local storage API. We've written a detailed plain-English explanation here if you want the full picture.
Is my data backed up automatically?
No — and that's intentional. Because nothing leaves your device, there is no automatic cloud backup. You should export a backup JSON file regularly using the Export button in the app. Keep it somewhere safe (a folder on your computer, an encrypted drive, etc.).
I switched devices and my data is gone.
Local storage is isolated to the browser and device it was created on. To move your data, export a backup JSON from your old device, then use Import on your new device. If you didn't export a backup, the data cannot be recovered.
Does Fieldnote work offline?
Yes. Once the app has loaded, it works entirely offline. There are no network requests during use.
What happens if I clear my browser data?
Clearing browser data (cookies, site data, or local storage) will delete your tracking data. If you use private/incognito mode, data is also deleted when the window closes. Export a backup before clearing anything.
Can I use the same app on multiple devices?
Yes, but data is not synced between them. Export a backup from one device and import it on the other to get in sync. After that, you'll need to keep both up to date manually or pick one as your primary device.
Do you sell my data?
No. We don't receive your data in the first place — it never leaves your device. You can read about how health data brokers work and why this matters in this article.
What analytics do you collect on fieldnote.health?
The marketing website uses Umami for privacy-friendly analytics (page view counts, no personal data). You're asked for consent on your first visit. The apps themselves collect nothing. Full details in our Privacy Policy.
