# Local-first tradeoffs

> The explicit tradeoffs of Retina's local-first model: per-device storage, no backup if you clear site data, no background snapshots, no shared portfolios.

Local-first is the right default for portfolio data. It is also a set of explicit tradeoffs.

## Per-device, per-browser

Your snapshots and wallets live in the browser storage of the current browser on the current device. They do not follow you to a second device. Opening Retina in Chrome on your laptop and Safari on your phone gives you 2 separate setups.

## Clearing site data deletes it

Browsers expose a "Clear site data" or "Clear browsing data" action. Running it for `useretina.xyz` deletes every snapshot, wallet, manual position, and the Diapleo key.

<Warning>
  There is no Retina-side backup. If you clear site data without exporting, the data is gone. Export from the [Positions](/pages/positions) page before clearing.
</Warning>

## No background snapshotting

When the tab is closed, no snapshots are created. Snapshots are always taken when you click **+ Snapshot** with the tab open.

## No team-shared portfolios

A portfolio is bound to its browser. There is no shared workspace, no read-only link, no team view.

## Sync is on the roadmap

Multi-device sync via Arcium Multi-Party Computation is planned but not shipped. See [Roadmap](/roadmap).
