Notulee was built around a simple promise: your notes are yours, and they stay on your machine. This page explains, plainly, how that works — and the one small exception.
Where your notes live
Every note is stored on your own device, as a plain Markdown file in a folder you choose — so you can always read, move or back them up yourself, with or without Notulee. There is no registration and no sign-in. We never see your notes, because they are never sent anywhere.
Every smart feature is on-device
The “superpowers” — math, unit and currency conversion, reactive variables, checklists, sums, readability scoring and search — all run locally, and always give the same result for the same input. They’re deterministic, not predictive, so nothing about what you type is sent anywhere to be evaluated.
Notes that never touch disk
Some notes are meant to be temporary. A disappearing note lives in memory only — it is never written to disk and never included in a backup, and it self-destructs when you quit Notulee, after a timer, or the moment you switch away. It’s the right home for an API key, a password or a one-time code.
Notulee also watches what you paste: if it spots something that looks like a secret — an API key, password or token — it offers to tuck it into a memory-only note instead of writing it into a saved one. That check runs entirely on your device, like every other smart feature; nothing about what you paste is sent anywhere.
When Notulee reaches the network
Two features can reach the internet, and only these two: currency conversion, which fetches a sheet of exchange rates, and stock quotes, which look up a ticker’s latest price. Both requests:
- contain none of your note content — they send only a public currency code or a ticker symbol, never what you wrote;
- are cached, so they aren’t re-fetched on every keystroke;
- happen only when you use them — a conversion or a
$TICKERin a note.
Currency rates are cached locally, so conversions keep working offline; a stock price is live by nature, so a fresh quote needs a connection. If you use neither, Notulee makes no network requests at all.
No telemetry in the app
The Notulee app contains no analytics, crash trackers, advertising SDKs or usage telemetry. It doesn’t count your launches, time your sessions, or phone home. That’s a firm promise about the app itself — the marketing site you’re reading is covered separately, just below.
This website
This marketing site is separate from the app. To see roughly how many people visit, it uses privacy-respecting, cookieless analytics (Cloudflare Web Analytics) — it sets no cookies, builds no personal profile of you, and doesn’t follow you across the web. There are no advertising trackers and no sign-up forms, so we don’t collect your email or anything else. The live demo runs the app entirely in your browser; nothing you type in it is uploaded.
Questions
This is a living document for a product that’s still evolving, so specifics may change. The principle, though, won’t: your notes stay on your device.
