As answered by people managing Linux-libre and PrivacyNotes.
PrivacyNotes's answer:
People who want their private life in one private place: notes, plans, passwords, a journal and health records. It fits independent professionals who keep sensitive material, such as lawyers, journalists, therapists, doctors, developers, researchers and founders. It also fits anyone who is tired of paying for five apps that each hold one part of their life.
PrivacyNotes's answer:
React, TypeScript, Vite and Tailwind CSS.
PrivacyNotes's answer:
PrivacyNotes keeps your notes, tasks, passwords, journal, files, calendar, contacts and bookmarks in one app, with mood and medication tracking. Everything is encrypted on your device with XChaCha20-Poly1305, under a key from a 12-word recovery phrase. Most privacy apps do one of these jobs and charge for it every month. PrivacyNotes does all of them, and Pro is a one-time purchase. The apps are open source, so anyone can check what they do.
PrivacyNotes's answer:
Three reasons:
PrivacyNotes's answer:
PrivacyNotes started from a simple frustration: staying organized meant spreading your life across half a dozen apps, each with its own monthly bill. We wanted one place for notes, tasks, a journal, files and passwords, encrypted on your device, and paid for once instead of forever. So we built the encryption first, made it the base of every feature, and published the apps as open source so the promise can be checked, not just believed. Everything else grew from one rule: your data is yours.
PrivacyNotes's answer:
We do not keep a customer list to show, and that is on purpose. You can sign up with only a 12-word phrase, with no email and no name, and the app has no trackers and no analytics. So we do not profile the people who use it. A privacy product that watched its users closely enough to name them would miss its own point.

The best thing about this: No subscription model, it's a one-time fee for a lifetime license. But you can start for free with the generous freemium model. I only needed to upgrade to pro because I wanted to use...
