PrivacyNotes is a zero-knowledge encrypted workspace that brings your notes, tasks, journals, files, and passwords into one app, so you stop juggling four separate subscriptions.

Everything is encrypted on your device with XChaCha20-Poly1305 before it ever syncs. Your keys are derived from a recovery phrase that never touches our servers, so we cannot read your content, your filenames, or anything else. This is real zero-knowledge, not a marketing label.

Five pillars, one encrypted app:

  • Notes - a live markdown editor with note-to-note links, tags, and fast full-text search
  • Tasks - native checklists and task management next to your notes
  • Journals - daily entries with built-in mood, sleep, and medication tracking
  • Files - an encrypted vault for images, audio, and attachments
  • Vault - lock sensitive notes and logins behind a PIN or biometrics

Built for privacy, not surveillance:

  • No ads, no trackers, no analytics, ever
  • Sign in anonymously with a recovery phrase or with Google. No email or personal details required.
  • Open core: the encryption layer and database schema are published for independent review
  • Burn notes: self-destructing shares the server cannot read

Pricing that respects you:

  • Free covers every pillar with two-device sync and offline use
  • Pro is a one-time free, not a subscription, adding unlimited devices, note history, and more storage
  • Optional storage add-ons when you need them

Works on web, macOS, and soon iOS, Android, Windows and Linux with a responsive mobile layout. Import from Apple Notes, Standard Notes, Google Keep, Obsidian, and markdown in a few clicks.

SharpKeys features and specs

  • Open Source
    SharpKeys is available on GitHub, which means it is open source. This allows users to inspect the code, contribute to development, or customize it for their needs.
  • Free of Cost
    SharpKeys is entirely free to use, making it accessible to anyone without the need for a commercial license.
  • Simple User Interface
    The interface is straightforward and easy to use, which makes the process of remapping keys simple even for non-technical users.
  • Registry-Based Remapping
    SharpKeys makes changes directly to the Windows registry, ensuring that the remapped keys work across all applications without the need for additional software running in the background.
  • Minimal Resource Usage
    Because SharpKeys modifies the registry rather than running a constant background process, it uses minimal system resources.
  • Portability
    Once the registry changes are made, SharpKeys does not need to remain installed on the system, making it a lightweight, one-time-use tool.

Possible disadvantages of SharpKeys

  • Windows Only
    SharpKeys is designed to work exclusively on Windows operating systems, which limits its usability for users on macOS, Linux, or other platforms.
  • Limited to Registry
    The tool operates by modifying the Windows registry, so it cannot handle complex remapping scenarios that need real-time processing, such as conditional key mappings.
  • No Advanced Features
    SharpKeys lacks advanced features found in more sophisticated key remapping software, such as macro recording, multi-key remapping, or application-specific profiles.
  • Requires Admin Rights
    Since changes are made to the Windows registry, administrative privileges are required, which might be restrictive in some organizational environments.
  • Potential for Errors
    Incorrect registry changes could potentially lead to system instability or errors, especially for users who are not familiar with the Windows registry.
  • Reboot Required
    For registry changes to take effect, a system reboot is necessary, which can be inconvenient for users needing immediate results.

PrivacyNotes features and specs

  • 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.

Analysis of SharpKeys

Overall verdict

  • SharpKeys is generally considered a good tool for users who need an easy and effective way to remap keys on Windows. It has a straightforward interface and does not require advanced technical skills to use, making it accessible to a wide range of users. It is also open-source and has a supportive community on GitHub, which contributes to its reliability and improvement over time.

Why this product is good

  • SharpKeys is a utility that allows users to remap keys on their Windows keyboards. It modifies the Windows Registry to achieve this, which is particularly useful for users who want to change the function of a specific key, disable a key, or swap keys to better match their personal typing preferences or overcome keyboard limitations.

Recommended for

    SharpKeys is recommended for Windows users who need to customize their keyboard layout, such as programmers, writers, or anyone who frequently uses specific key combinations. It is also suitable for users who want to disable keys that are accidentally pressed often, such as Caps Lock or Insert, as well as those who want to swap keys for ergonomic reasons or due to a damaged key on their keyboard.

Analysis of PrivacyNotes

Overall verdict

  • I don't have verified, specific information about PrivacyNotes (privacynotes.app) to make a reliable assessment of its quality, security practices, or features. I cannot confirm details about its encryption methods, privacy policy, company background, or user reviews.

Why this product is good

  • Unable to verify claims about encryption or zero-knowledge architecture without independent confirmation
  • No access to current user reviews, ratings, or reputation data for this specific service
  • Cannot confirm company legitimacy, ownership, or track record
  • Unable to verify uptime, reliability, or actual security audit results
  • No information available on pricing structure or terms of service specifics

Recommended for

  • Before using, research independently via security audit reports if available
  • Check for third-party security reviews or penetration testing results
  • Verify the company's privacy policy and data handling practices directly on their site
  • Look for user reviews on independent platforms rather than relying on marketing claims
  • Consider established, well-audited alternatives if handling highly sensitive information

Questions & Answers

As answered by people managing SharpKeys and PrivacyNotes.

Who are some of the biggest customers of your product?

PrivacyNotes's answer:

Honestly? We have no idea, and that is the entire point. Signup is anonymous (a recovery phrase or Google, no email or personal details), the app ships zero analytics and zero trackers, and zero-knowledge encryption means we cannot see who you are or what you store. We could not name a single customer if we tried. A privacy product that tracked its users closely enough to brag about them would be missing the plot.

What makes your product unique?

PrivacyNotes's answer:

PrivacyNotes is the only zero-knowledge encrypted workspace that keeps notes, tasks, journals, files, and a password vault behind one set of on-device keys. Most privacy apps do one of those well and rent it to you monthly. We do all five, encrypt everything with XChaCha20-Poly1305 before it leaves your device, and charge once instead of forever. The encryption core is open core, published so the claims can be verified rather than trusted.

Why should a person choose your product over its competitors?

PrivacyNotes's answer:

Three reasons:

  • One app, not four subscriptions. Standard Notes, Day One, and Lunatask each rent you a slice (notes, journaling, tasks). PrivacyNotes covers all of them plus files and a vault, for a fair one-time fee.
  • Real zero-knowledge. Your keys come from a recovery phrase that never touches our servers, so we cannot read your notes, your filenames, or your metadata. Some encrypted apps leave note or task metadata in the clear; we do not.
  • Verifiable, not just trusted. The crypto and schema are open core and published for review, and there is no ad, tracker, or analytics anywhere in the app.

How would you describe the primary audience of your product?

PrivacyNotes's answer:

Privacy-conscious individuals and independent professionals who handle information they would not want a vendor reading: lawyers, journalists, healthcare and mental-health practitioners, developers, security specialists, researchers, and founders. It also fits anyone who simply wants one private home for their notes, tasks, journaling, and wellness tracking instead of spreading them across surveillance-funded apps.

Which are the primary technologies used for building your product?

PrivacyNotes's answer:

React, TypeScript, Vite and Tailwind CSS.

What's the story behind your product?

PrivacyNotes's answer:

PrivacyNotes started from a simple frustration: staying organized meant scattering your life across half a dozen apps, most of which could read everything you typed and billed you monthly for the privilege. We wanted one place for notes, tasks, journals, files, and passwords, encrypted so thoroughly that the people running the servers could not read a word of it, and paid for once rather than forever. So we built the encryption first, made the keys live only on your device, and published the crypto as open core so the promise could be checked, not just believed. Everything else grew from one rule: your data is yours, and no one else's to mine.

    Feature rich

    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 the app on my phone, laptop and desktop. Highly recommended! Btw, it's a perfect markdown editor as well, not sure why they don't emphasize this more.

  • I Hate (Most) Keyboard 'Fn' Keys
    You can remap the keys so that "Special: Power" key button does nothing.. Or even to the original function (on my keyboard it would mean Volume Down would be F12 instead). One Windows software to do that: https://github.com/randyrants/sharpkeys / https://apps.microsoft.com/detail/xpffcg7m673d4f?hl=en-US On Linux, heck it's Linux, for sure it's doable. - Source: Hacker News / about 1 month ago
  • Shortcut for rotating canvas by 15ยฐ left or right without a mouse
    I don't like using my mouse while drawing and I couldn't find how to do this anywhere, but luckily when I was about to give up I achieved it! So, for this you'll need a program called SharpKeys. You can download it here: https://github.com/randyrants/sharpkeys/. Source: over 2 years ago
  • Caps Lock Behaviour Disabled in Gnome
    Sharpkeys can swap keys, the readme says as much: > Things that SharpKeys will do: > ... > Allow you to swap two keys with each other - e.g. You can swap Left Windows with Left Control and vice versa I do have a vague recollection of Sharpkeys previously saying that it couldnโ€™t, but that I tried and it worked. Long time since I last used Windows though. - Source: Hacker News / almost 3 years ago

    > Total commander isnโ€™t FOSS. I'm aware of that. There are lots of FOSS equivalents, though. Including, I believe, on Windows. Wikipedia lists 23 of which I think -- haven't checked -- the majority are FOSS. https://en.wikipedia.org/wiki/File_manager#Orthodox_file_managers > Ironically windows 11 canโ€™t do vertical taskbars.
