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.

Possible disadvantages of SEOptimer

  • Limited Advanced Features
    For advanced users or larger enterprises looking for more sophisticated SEO features and functionalities, SEOptimer might not be as comprehensive as some of the more specialized tools available.
  • Lack of Historical Data
    SEOptimer does not provide historical data tracking for websites, which can be a limitation for users who need to monitor SEO performance over time.
  • Limited Integration
    The tool offers fewer integrations with other SEO and analytics platforms compared to some of the more established tools, which could restrict workflow efficiency for some users.
  • Basic Keyword Analysis
    While SEOptimer provides keyword analysis, it does not offer as robust a keyword research feature set as dedicated keyword research tools.
  • Depth of Data
    The level of data granularity might not be sufficient for power users or SEO specialists who require deep and comprehensive insights for decision-making.

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 SEOptimer 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.

  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.
