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. 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.
The one network call
The only feature that can reach the internet is currency conversion, which fetches a sheet of exchange rates. That request:
- contains none of your note content — it only asks for public rates;
- is cached locally, so conversions keep working offline afterwards;
- can be bypassed entirely by pinning your own custom rates.
If you never use currency conversion, 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 in development, so specifics may evolve before launch. The principle, though, won’t: your notes stay on your device.
