"Three things I kept: morning walks, reading before bed, saying no to things that drain me. Three things to build this year: patience, presence, Portuguese. One thing to let go: the version of myself that needs to explain everything."

Journaling & Reflection
A journal that's actually private
Your most honest thoughts deserve the most private home. VaultBook's journal is encrypted, offline, and completely unseen by any company, algorithm, or advertiser. It runs from a single file on your machine — nothing ever leaves it.
1
Write freely — rich text or plain prose
Headings, callouts, blockquotes, bold, and checklists — or just free-flowing paragraphs. VaultBook gets out of the way.
2
Tag mood, themes, and recurring feelings
Labels like "Grief", "Gratitude", "Milestone" let you trace emotional patterns across months and years automatically.
3
Search your past self in natural language
"What was I feeling in October 2023?" returns exact entries ranked by relevance. Revisit any season of your life in seconds.
4
Encrypt the entries that need it most
Therapy notes, grief entries, and anything truly vulnerable get AES-256-GCM with an independent password only you know.

Health & Habits
Your health data belongs to you
Fitness apps sell your data. Health apps sync to clouds you don't control. VaultBook keeps your symptoms, medications, cycle tracking, sleep data, and mental health notes on your device only — encrypted if you want, searchable always.

Log habits with labels and weekly views
Create daily habit entries with labels like "Exercise", "Medication", "Sleep". The Timetable view shows every habit in a weekly grid automatically.

Attach your medical documents
Blood test PDFs, doctor's notes, prescription scans — deep indexed and searchable. "What was my ferritin in March 2024?" returns the result.
3
Find patterns QA search reveals
"When do my migraines cluster?" surfaces the symptom log entries. Spot what your memory doesn't track but your notes do.
4
Encrypt everything truly sensitive
Mental health notes, cycle logs, and therapy summaries each have an independent AES-256 password. No shared key, no shared risk.

Personal Finance
Your finances deserve real privacy
Salary details, investment allocations, and net worth are among the most sensitive things you own. A finance tracker that syncs to any server is a liability. VaultBook keeps every number, note, and spreadsheet on your machine — encrypted, searchable, and yours.

Encrypt every sensitive entry
Salary notes, investment decisions, and net worth each get their own AES-256 password — fully independent and isolated.
2
Attach and index your spreadsheets
Drop in your XLSX budget models or investment trackers. Every cell is searchable — find any figure without opening the file.

Build a decision log for money choices
Record why you made each major financial decision. "Why did I choose this fund?" is answerable years later with your own reasoning attached.

Privacy by architecture
Your personal life deserves personal privacy
The most intimate things you'll ever write deserve the strictest guarantee. VaultBook provides it through architecture, not policy.
🚫
Zero network requests. Ever.
VaultBook makes no outgoing connections — not for sync, not for analytics, not for "improving the product". Your journal entries, health logs, and financial notes are never transmitted anywhere. Disconnect from the internet and nothing changes.
🔐
Per-entry encryption, per-entry password.
Each encrypted entry uses AES-256-GCM with its own unique 16-byte salt, 12-byte IV, and key derived from 100,000 PBKDF2 SHA-256 iterations. Therapy notes, financial records, and grief entries each have an independent password. One compromised key never exposes another.
📁
Plain files. Your folder. Your rules.
VaultBook stores everything as JSON files in a folder you choose. Back it up with Time Machine, copy it to a USB drive, or keep multiple copies across machines. You don't need permission, an export button, or an internet connection to access your own life's data.
What this means in practice
Nobody has ever seen your vault. Including us.
We don't have a server that stores your entries. We don't have an API that receives your searches. We don't have telemetry that logs your usage. VaultBook is a file that runs in your browser — between you and your machine, and nowhere else.
✓
If VaultBook shuts down tomorrow
Your data stays in your folder, unchanged. The HTML file keeps working in any Chromium browser indefinitely.
✓
If there's a data breach somewhere
Nothing leaks — there's nothing on any server to breach. Your data has never left your machine.
✓
If the app's terms of service change
Irrelevant. You own the file. No terms of service can retroactively govern data that was never transmitted.

What a personal library looks like after five years
The value of VaultBook isn't what you capture today. It's the searchable record of everything you've ever cared about.
📖
Month 1
You start journalling. A few entries a week.
Daily notes, some habit tracking, a recipe to remember. The archive is small — but the habit of capture is forming. Search already works, even on 20 entries.
~20 entriesLabels taking shapeFirst encryption
✈️
Month 6
A trip gets captured properly for the first time.
Day-by-day notes, restaurant names OCR'd from photos, a budget spreadsheet attached and indexed. You realise this beats any travel blog you'd never actually write.
~180 entriesFirst deep-indexed PDFsPage tree forming
🧠
Year 1
QA search starts earning its keep.
"What was that café in Lisbon?" or "When did the ankle pain start?" return exact entries you'd completely forgotten writing. The library starts paying dividends.
~600 entriesVote learning activeHealth + finance encrypted
💡
Year 2
Related Entries becomes a daily surprise.
You open a note and VaultBook surfaces something you wrote 14 months ago on the same theme. Ideas begin connecting across time. The library thinks alongside you.
~1,400 entriesRelated Entries in daily useSearch fully personalised
📚
Years 3–5
It becomes a record of who you are.
Yearly reviews show growth. Old journal entries feel unrecognisable and invaluable. The knowledge base holds more of your mind than memory can. No cloud company has ever seen any of it.

You share it, or you don't. That's the point.
Everything lives in a plain folder you own. Copy it to a new machine by copying a folder. Encrypt the whole thing at the OS level if you want. Nobody has a copy — not even us.

What they say about VaultBook in their lives
"
I've tried every journalling app. The problem was always the same — at some point you read the privacy policy and realise your most honest writing is sitting on a server being scanned for "product improvement". VaultBook fixed that. It runs from a single file, makes zero network requests, and the encrypted entries are genuinely sealed. I've written things in VaultBook that I would never write in any cloud tool. That freedom changes what journalling actually is.
Five-year archive snapshot
January 1, 2021 · Entry #1
"Starting this as an experiment. Let's see if it sticks."
December 31, 2023 · Year 3 review
"Read back three years of entries tonight. Didn't recognise the person from 2021. That's either terrifying or the whole point."
March 5, 2026 · Entry #2,847
"Searched 'when did I stop being afraid of X?' — found the exact entry from Feb 2022. None of these 2,847 entries have ever left this machine."
"
My health journey over three years — symptoms, medications, what worked and what didn't — is all searchable. My doctor is always impressed that I can pull exact dates and dosages. The fact that none of it has ever touched a health company's server is the only reason I'm honest enough to write it all down.
"
I'm building a family archive for my children. Old photos, stories from my parents, letters I want them to find someday. The encrypted entries mean I can write things that are meant to be read at a specific time — by specific people — without worrying about a data breach in the meantime.
Questions
FAQ for personal use
Can I access VaultBook on my phone?▾
VaultBook runs in any Chromium-based browser. Chrome on Android is fully supported. On iOS, Chrome and Edge work best. Because it's a single HTML file, you can open it directly from your Files app on mobile. For the richest experience — especially inline OCR and attachment indexing — Chrome desktop remains the primary environment, but all reading and writing works well on mobile.
How do I back up my journal if my laptop dies?▾
VaultBook stores everything in a plain folder you choose. Back it up with any tool you already use — Time Machine, iCloud Drive, Google Drive, an external SSD, or rsync. The data is plain JSON files. Encrypted entries stay encrypted in the backup and can only be decrypted with the correct password. You don't need VaultBook running to back up — just copy the folder.
Is my encrypted data truly private — even from VaultBook?▾
Yes. VaultBook makes zero network requests — there is no server, no account, no way for us to receive your data. Encrypted entries use AES-256-GCM with PBKDF2 at 100,000 SHA-256 iterations, a unique 16-byte salt, and a unique 12-byte IV per entry. We don't have your password and couldn't decrypt your entries even if we wanted to. See the Security page for the full technical specification.
Can I use VaultBook as a shared family journal or couple's diary?▾
Yes. Point multiple devices at the same vault folder (via a shared drive, NAS, or sync folder) and anyone with the app can read and write to it. Use per-entry encryption to keep some entries private within the shared folder — each person's private entries have their own independent password that others don't know. No per-seat pricing and no accounts to manage.
How is this different from Day One or Notion for personal use?▾
Day One syncs your journal to their servers and processes it on their infrastructure. Notion is similarly cloud-first. Both require accounts and ongoing subscriptions. VaultBook makes zero network requests, stores everything locally, and supports per-entry AES-256 encryption we can't break. Beyond privacy, VaultBook also indexes attached PDFs, XLSX, and images via OCR — so your recipe scans, medical documents, and travel photos all become searchable knowledge, not just stored files.
What happens to my data if VaultBook shuts down?▾
Nothing changes. Your data is in a folder on your device — not on our servers. If VaultBook stopped existing tomorrow, you'd still have every entry you ever wrote, every attachment, and every version snapshot. The HTML file itself continues to work indefinitely in any Chromium browser. You don't need our servers, our permission, or an internet connection to access your own data.
How do I import from Obsidian, Day One, or Evernote?▾
VaultBook includes a built-in Obsidian importer — drag your
.md files in and they're converted to searchable VaultBook entries immediately, preserving all frontmatter as labels. For Notion exports (Markdown + CSV) and Evernote exports (.enex), the same Markdown import handles the content. Attachments can be copied directly into your attachments folder and reindexed with the ♻️ button.Does VaultBook work on planes and in places without internet?▾
Completely. VaultBook is a single HTML file — once it's open in your browser, it makes zero network requests for anything at all. AI search, OCR, encryption, Kanban, version history, and all built-in tools run entirely inside your browser's JavaScript runtime. Disconnect from the internet and nothing changes. This makes it ideal for long-haul travel, secure facilities, and anywhere you value both productivity and privacy.
Your inner life deserves a place that's truly yours.
Download VaultBook — open it, write something, and keep it entirely to yourself. No cloud, no account, no one watching.
