# Snapshots

> How Retina captures a point-in-time view of every wallet, position, price, APY, and maturity, and how the active snapshot drives every page in the app.

A snapshot is a captured point-in-time of your full portfolio. It is the most important concept in Retina.

## What a snapshot captures

At the moment you create a snapshot, Retina freezes:

* Every position from every wallet
* Prices at that moment
* APYs at that moment
* Polymarket markets and positions
* Metals holdings and spot prices
* Maturities

The active snapshot is shown at the top of the sidebar, for example `Snapshot #1 | 2026-05-12`.

## Creating a snapshot

Click **+ Snapshot** in the top-right of the app. Retina re-fetches positions live from every source, then writes the result into a new snapshot.

The very first snapshot is created when you click **Create Snapshot →** at the bottom of the [setup wizard](/getting-started/quickstart).

## When to create one

There is no automatic snapshotting when the tab is closed. You decide the cadence. Common rhythms:

* Daily, at the same time
* Once a week
* Before and after a big rebalance
* Before claiming a reward or rolling a maturing position

## Where snapshots live

Snapshots are stored in browser storage on the current device. They are not synced anywhere. See [Local-first explained](/privacy/local-first).

## How the active snapshot affects every page

Every page in the app (except the live-API pages, see below) reads from the active snapshot:

* The Dashboard shows the total and the delta from the **previous** snapshot.
* The Wallets, Protocols, Maturity Ladder, and Positions pages list what existed at that moment.
* The History page is a roll-up of every snapshot you have created.

Live exceptions:

* The [Polymarket](/pages/polymarket) page calls Polymarket's public API on load.
* The Yield Table APY column on the [Dashboard](/pages/dashboard) is live.

## Clearing snapshots

The **🗑 Clear all** button wipes every snapshot, wallet, and manual position from this browser.

<Warning>
  **🗑 Clear all** is destructive and has no undo. Export from the [Positions](/pages/positions) page first if you want to keep the data.
