FAQ

Short answers to common questions.

Do I need an account?

No. There are no accounts and no email. A pool is a pool ID plus a secret, carried in a join code. No Google account is needed either.

Which browsers are supported?

Any Chromium browser that can load extensions: Chrome, Brave, Edge, Vivaldi, and others. Firefox and Safari are not supported.

Does it sync passwords, history, or settings?

No. It syncs bookmarks and user-installed extensions only.

What happens when two browsers change something at once?

The server puts all changes into one linear revision log. Every browser applies the log in the same order and converges on the same state. There are no conflict prompts.

Can the server read my bookmarks?

No. The server stores ciphertext, ciphertext hashes, keyed state hashes, and device public keys. The pool keys are derived from the secret on your devices and never reach the server.

I lost my join code. Can I recover the pool?

Open any browser that is still in the pool and reveal the join code. If no browser is in the pool anymore, the data cannot be decrypted — the server cannot recover the secret.

Why did joining replace my bookmarks?

A pool is a strict mirror, so joining replaces local data by design. If the browser was already in the pool, restore any revision from the last 30 days. Otherwise, re-import the export that you made before joining.

Is it open source?

Yes, under the O’Saasy license. You can read the code, file issues, and self-host the server on your own Cloudflare account.
