CV / 002How to start

Three steps to your own vault.

No sign-up and no server. The first vault takes a minute.

  1. Download the app

    macOS, Android, iPhone and iPad. From a store or as a direct build: version and checksums are on the release page.

    To the downloads

  2. Create a vault

    No sign-up: the vault is created right on the device. Its password stays with you and cannot be recovered, by you or by us.

    How protection works

  3. Bring your old data and make a backup

    Import accepts 1Password and KeePass exports and CSV from other managers. A backup is an encrypted file you keep yourself.

    About import and backups

Once you are settled in, use the vault beyond the app: from your computer, in the browser and in the terminal, where your platform supports it. See the modules

CV / 003What is different

Stored right here.

Most private-data apps are built around an account and a server. ChromVoid is built around your device: the vault is encrypted and stays with you, no cloud account needed.

You decide what to keep and who gets access.

The difference is where the data lives.

That changes every scenario, from the browser to being pressed for a password.

01
Where the source of truth is

The vault lives on your device, not a server.

UsuallyThe account on a server is the source of truth. Devices keep a copy, and access depends on the service.

In ChromVoid

The vault lives on your device. There is no ChromVoid account to create, and no copy of the vault on a server.

02
The browser

An extension that keeps no copy of your passwords.

UsuallyA built-in manager or an extension keeps its own copy of passwords in the browser profile.

In ChromVoid

The extension stores no secrets. It talks to the desktop app on the same computer, and autofill works only while the vault is unlocked.

How the extension works
03
Files and notes

Files open inside the vault.

UsuallyAn attachment is decrypted into a temporary folder and opened by another program.

In ChromVoid

Files, media and notes open inside the vault with the built-in viewer, player and editor. Handing them out is a separate, explicit action.

When you need a regular folder
04
Access from another device

Your phone is the host, not a cloud.

UsuallyEvery device syncs through a server that holds the whole vault.

In ChromVoid

The phone remains the host. A paired computer connects through a relay that sees only sealed envelopes. This is not sync and not a backup.

How access works
05
Under pressure

Different passwords, different vaults.

UsuallyOne master password opens everything, and a “wrong password” error confirms the vault exists.

In ChromVoid

Any password opens some vault; separate spaces exist for coercion scenarios. The limits are stated plainly: the app’s presence and the total data size cannot be hidden.

When ChromVoid is not the right fit

If you need shared team vaults, seamless sync across every device, or password recovery by support, the ChromVoid model will get in your way rather than help. A backup is a file you keep yourself. Hardware FIDO keys are not supported yet; Windows and Linux builds are planned.

CV / 004Reasons to trust

Fewer promises. More transparency.

Protection needs clear principles. And clearly stated limits.

Open-source Core

The Core source is open. You can study how ChromVoid works with your vault.

Verifiable builds

Direct builds come with a version, release notes and checksums. You can check the file you downloaded against the published one.

Difficult situations, without guarantees

Hidden spaces and coercion scenarios have limits. They cannot guarantee that the presence of private data is impossible to establish.

Understand the limits

CV / 005Modules

One vault, wherever you work.

Modules connect the vault to your browser, system autofill, your computer and the terminal. Each one works where your platform and app version support it.

CV / 006Good to know

Questions and answers.

Do I need a cloud account?

No. The vault works without signing up: there is no ChromVoid account, and your data stays on your device.

Can I move my passwords from another manager?

Yes. The app accepts 1Password exports (.1pux), KeePass databases (.kdbx) and the CSV or JSON files that Bitwarden, Chrome and most other managers produce. The import runs on your device.

How do I back up, and what if I lose my device?

A backup is an encrypted file you keep yourself: on a drive, a USB stick or any cloud. The medium only ever holds ciphertext. Without a usable copy and the vault password, recovery is impossible, and we cannot do it for you.

Recommendations in the threat model
Does every platform have every feature?

No. Available builds are listed in the download section. Modules depend on the platform, OS integrations and app version; each module’s description says where it works.
