Features and specs

What each product offers, as listed by its team.

Linux kernel 5 features
PrivacyNotes 5 features
  • Open Source
    The Linux kernel is released under the GNU General Public License, allowing users to view, modify, and distribute the source code freely. This promotes transparency, collaboration, and innovation within the community.
  • Customizability
    Due to its open-source nature and modular design, users can customize the Linux kernel to suit specific needs by enabling or disabling features, which is particularly beneficial for embedded systems or unique hardware environments.
  • Security
    The many contributors working on the Linux kernel can quickly identify and fix security vulnerabilities, and the kernel's design allows for implementation of strong security measures, making it a preferred choice for many security-conscious applications.
  • Stability and Reliability
    Linux is known for its stability and reliability, capable of running for years without crashing or needing a reboot, which is crucial for server environments and critical applications.
  • Hardware Support
    The Linux kernel supports a wide range of hardware architectures and devices due to the contributions of developers across the globe, which allows it to be used on everything from supercomputers to smartphones.

Possible disadvantages

  • Complexity
    The Linux kernel's extensive feature set and flexibility can lead to complexity, making it difficult for beginners to understand and configure without a steep learning curve.
  • Limited Commercial Support
    Unlike some proprietary operating systems, Linux may have limited dedicated support options, which can be a challenge for companies that require guaranteed, on-demand technical support.
  • Software Compatibility
    Some commercial software applications and games are not natively supported on Linux, which can limit its usability for certain users unless they use compatibility layers like Wine or alternative software.
  • Device Driver Availability
    While the Linux kernel supports a variety of hardware, some cutting-edge or proprietary devices may lack official drivers, requiring users to rely on community-driven development or workarounds.
  • Fragmentation
    The flexibility of Linux allows for numerous variations (distributions), which can result in fragmentation. This diversity can confuse new users and complicate software compatibility across different systems.
  • Privacy-focused
    PrivacyNotes is designed with privacy as a core principle, aiming to keep your notes secure and away from third-party access, which appeals to users concerned about data confidentiality.
  • Encryption
    The service typically emphasizes encryption to protect note content, meaning your data is scrambled and less vulnerable to unauthorized reading if intercepted or stored.
  • Ephemeral notes
    Many privacy note services offer self-destructing or temporary notes that automatically delete after being read or after a set time, reducing the digital footprint left behind.
  • Simple and lightweight
    Such tools often provide a clean, minimal interface focused on quick note creation and sharing without unnecessary features, making it easy to use.
  • No account required
    Privacy-oriented note apps frequently allow you to create and share notes without registration, lowering the barrier to entry and reducing personal data collection.

Questions & Answers

As answered by people managing Linux kernel and PrivacyNotes.

How would you describe the primary audience of your product?

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.

Which are the primary technologies used for building your product?

PrivacyNotes's answer:

React, TypeScript, Vite and Tailwind CSS.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

PrivacyNotes's answer:

Three reasons:

  • One app, not a stack of subscriptions. Standard Notes, Day One, Daylio and Bitwarden each cover one part of your life. PrivacyNotes covers all of them, with one price, paid once.
  • Encrypted on your device. Your notes are always encrypted, on your device and on the way to our servers in Zurich, Switzerland. With self-custody, the server holds nothing that opens your notes.
  • Open source, no ads, no trackers. The apps and the encryption code are published for review, and there is no ad, tracker or analytics of what you write anywhere in the app.

What's the story behind your product?

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.

Who are some of the biggest customers of your product?

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.

    This app checks every box for me. Clean interface, no learning curve, local-first encryption, and secure sync across all of my devices. The biggest surprise is how many apps it replaced. Instead of juggling separate...

    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...
