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.

Blockchain features and specs

  • Security
    Blockchain provides strong security features, as each transaction is encrypted and linked to the previous one. This makes it highly resistant to fraud and hacking.
  • Transparency
    All transactions on the blockchain are publicly accessible and verifiable, which increases transparency and trust among users.
  • Decentralization
    Blockchain operates on a decentralized network, which reduces the reliance on a central authority and increases system robustness and uptime.
  • Immutability
    Once data is recorded on the blockchain, it cannot be altered or deleted, ensuring the integrity and consistency of the data over time.
  • Efficiency
    Blockchain can streamline and automate processes such as cross-border payments, reducing transaction times and costs.

Possible disadvantages of Blockchain

  • Scalability
    Blockchain networks often face issues with scalability, as the system can become slow and less efficient as the number of transactions increases.
  • Energy Consumption
    Blockchain, especially proof-of-work-based networks like Bitcoin, require substantial computational power, leading to high energy consumption.
  • Regulatory Uncertainty
    The legal and regulatory environment for blockchain technology is still evolving, which can create uncertainty and compliance challenges.
  • Complexity
    Implementing and maintaining a blockchain system can be complex and require specialized knowledge and skills, which might not be readily available.
  • Data Privacy
    While blockchain ensures transparency, it can also be a double-edged sword as the data is publicly accessible, posing privacy concerns for sensitive information.

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.

Questions & Answers

As answered by people managing Blockchain 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.

PrivacyNotes Reviews

  1. Everything I Needed in One App

    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 apps for notes, habits, mood, activities, and important dates, everything lives in one place now. It's made staying organized a lot simpler.

    Paying once and knowing I won't lose access to my workflow because I canceled yet another subscription is incredibly refreshing. That peace of mind is worth a lot to me.

    ๐Ÿ Competitors: Capacities, Evernote, Notion, Obsidian.md
  2. 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 lost over $3000 to blockchain.com
    I used blockchain.com back in 2015. I remembered back in the day they gave you a private key for all your addresses. Looks like they don't now with their newer wallets. Source: over 2 years ago
  • i lost over $3000 to blockchain.com
    In blockchain.com u dont actually own the address, you can access your account, but the address is all blockchain property, so they choose which address you have access to and so forth. Source: over 2 years ago
  • best crypto wallet app
    I use blockchain.com as the receiving wallet because they wallet address changes often and some of these ghetto ass sites don't let you withdrawal to the same one more than once. Source: over 2 years ago
  • Older wallet, higher fees?
    So says blockchain.com. Is it true, and if so is there a way to update/replace my Electrum wallet to pay lower fees in the future? Source: over 2 years ago
  • What is your thoughts on SOFI?
    This is anecdotal and I have no idea what it means for SOFI business wise or stock wise moving forward but they just sent me a notice that they are no longer offering any forms of crypto buying or investing and they are selling/giving their current crypto customers to blockchain.com in a few weeks.
