A local-first notes app stores your notes on your own device by default and works offline. It is more private because your writing does not have to pass through a company’s servers to be usable.
Notes hold drafts, plans, half-formed ideas, and sometimes things you would never say out loud. It is worth choosing where they live. A local-first notes app keeps the working copy on your own device, which reduces how many other systems have to handle your text. It is not a guarantee of security, but it is a sensible default.
What “local-first” means
In a local-first app, the copy on your device is the real one. The app opens instantly, works with no connection, and does not need an account to function. Syncing, if offered, is an add-on rather than a requirement.
That differs from a cloud-first app, where the server holds the authoritative copy and your device shows a view of it. Cloud-first design has real advantages, such as easy collaboration and access from any browser. It also means the app depends on a connection, an account, and the company’s servers staying available.
Why it helps privacy
- Fewer copies. Fewer servers holding your text means fewer places it can be exposed, misconfigured, or requested.
- No account. Nothing to sign into, and no profile tying your notes to an identity.
- Ownership. Plain-text formats like markdown can be read without the app. See what an MD file is.
- Offline by default. If the app never needs a network to work, you can verify that for yourself by turning Wi-Fi off.
What local-first does not do
Being honest about limits matters more than the slogan. Local storage does not protect you from:
- A lost or stolen laptop. Use FileVault and a strong login password on your Mac.
- Backups you forgot about. Time Machine and cloud backups contain copies of your files too.
- Sync you turn on. If you enable sync through any provider, your notes are stored there as well. Read that provider’s documentation.
- Sharing mistakes. Exported PDFs and copied text are outside the app’s control.
Local-first versus cloud-first
| Question | Local-first | Cloud-first |
|---|---|---|
| Works offline | Yes, by design | Varies; often limited |
| Account needed | Often not | Usually yes |
| Real-time collaboration | Generally weaker | Generally stronger |
| Access from any browser | Usually no | Often yes |
| Where the main copy lives | Your device | The vendor’s servers |
| Leaving the product | Easier with open files | Depends on export tools |
Neither column is better for everyone. Notion, for instance, is a cloud workspace with databases and collaboration that requires an account; it suits team documentation far better than a local app does. Apple Notes sits in between: built in and synced through iCloud, but in a format only Apple’s tools use. Check each product’s site for current details on storage and privacy.
A worked example: three kinds of notes
Different notes deserve different homes. A practical split looks like this:
- Private thinking. Journal entries, drafts, and personal plans fit a local-first app well. No one else needs to read them, so there is little reason for them to leave your Mac.
- Shared work. Meeting notes and project documents that several people edit belong in a collaborative tool, accepting the account and cloud storage that come with it.
- Sensitive secrets. Passwords, banking details, and recovery codes belong in a password manager built for that purpose.
Sorting your notes this way is often more effective than searching for one perfect app. It also makes switching less stressful, since only one category has to move.
Questions to ask about any sync option
Optional sync is useful, but it changes where your notes live. Before turning it on, find out:
- Which provider stores the synced copy, and under which account?
- Is sync on or off by default?
- Can you turn it off later, and what happens to the copies already synced?
- What does the provider’s own documentation say about how data is protected?
atiea has no sync yet (iCloud sync is coming with the iPhone and iPad app): today notes stay on your Mac, so the only other copies are the ones you make yourself, such as Time Machine backups or exports.
What to look for
- Does it work fully offline? Try it with networking disabled.
- Can you export everything in an open format? Markdown, HTML, and PDF are good signs.
- Is sync optional and clearly explained? You should know which service holds your data if you switch it on.
- Does it ask for an account just to take a note? It should not.
- Is the privacy policy readable? Look for what is collected, if anything, and why.

A quick privacy checklist for your own setup
- Turn on FileVault for your Mac.
- Decide deliberately whether to enable sync, and for which devices.
- Keep an export or backup you control.
- Keep secrets such as passwords and recovery codes in a password manager, not in a notes app.
How atiea approaches it
atiea is a native Mac app (macOS 15 or later) that stores notes locally on your Mac and requires no account. You can export notes to Markdown, HTML, PDF, and DOCX at any time, which keeps your writing portable. See the about page for who builds it and the features for what it does day to day.
Inside the app you write in markdown with live syntax highlighting, link notes with [[wiki links]], and organize with inline #tags and pinned notes. We explain the linking model in what wiki links and backlinks are.
When local-first is not the right choice
- You collaborate in real time. A cloud workspace is built for shared editing; see the Notion comparison.
- You need a phone app. atiea runs on macOS only.
- You never back up. With a single local copy, a disk failure can mean data loss. Local-first works best alongside backups.
- You want a plugin ecosystem on local files. Obsidian also keeps files locally and has many plugins; see Obsidian alternatives for how options compare.
