Privacy Policy
Last updated: August 12, 2026
The short version
Your notes are saved as plain text files on your own device first. We collect the minimum needed to run your account. We never sell your data, and there are no ads.
What we collect
Account data. Your email address and the settings you choose. That’s what’s needed to sign you in and sync between your phone and computer.
Your notes. Notes are written to your device first. If you use sync, a copy is stored on our servers so your phone and computer stay in step.
Payment data. Payments are processed by Polar (as merchant of record) and Stripe. We never see or store your full card number — they send us only what’s needed to know that you paid.
Basic usage data. Crash reports and the minimum diagnostics needed to keep the app working. We don’t build advertising profiles and we don’t track you across other apps or websites.
Optional AI processing
Two jobs can use AI services run by other companies: reading a note so it can be filed, and turning speech into text. For those two jobs, and only those, the relevant text or audio is sent to those providers when you have the feature turned on. You choose whether to turn it on, and you can turn it off at any time. We publish the current list of providers and exactly what gets sent; if that list changes, we tell you before it affects you.
What we never do
We never sell your personal data. We never show ads. We never read your notes to market things at you.
How long we keep data
We keep your account data while your account is active. If you delete your account, we delete your account data and any synced copies of your notes from our servers within 30 days, except where the law requires us to keep something longer (for example, payment records, which Polar and Stripe retain as the law requires). Notes stored on your own device stay there until you delete them.
Your rights
You can export all of your notes at any time, free, on every plan. You can correct your account details in settings. You can delete your account in the app. Depending on where you live (including the EU, UK, and California), you may have additional rights — to access, correct, delete, or restrict processing of your personal data, and to complain to your local data protection authority. Email us to use any of them.
Security
We use encryption in transit and at rest for data on our servers. No system is perfectly secure; the design goal here is that the most important copy of your notes is the one on your own device.
Changes to this policy
If we change this policy in a way that matters, we’ll tell you by email or in the app before it takes effect, and we’ll update the date at the top of this page.
