# Three computers, one setup, none of it on our servers

Source: https://asorocket.app/features/sync-between-computers

A Studio licence works on three computers. Turn on sync and what you set up on one appears on the others, through a folder you already own in iCloud Drive, Dropbox or any other synced folder: the apps you follow, their countries and competitors, keywords and tags, and your Metadata lab drafts.

## What it does

### Your storage, not ours

Choose a folder in iCloud Drive, Dropbox or any folder your computers share. Each computer writes one small file there and reads the others’, so two computers never write the same file.

### Optional, and easy to leave

Off until you turn it on. Turning it off on a computer removes nothing you set up: that computer takes its own file out of the folder and the others keep what they took over from it. Turned on again later, it joins like a new computer.

### Still local first

Each computer keeps its own database and works offline, then catches up when the folder does.

### Keys stay on each computer

API keys and webhook addresses are encrypted by each computer’s operating system, so they don’t travel: connect a service once on each computer.

## Good to know

### Your setup travels, the figures don’t

Sync carries what you set up: followed apps, countries, competitors, the link between an app’s two store versions, keywords, tags, drafts and a few preferences. Each computer collects its own ranks, reviews and figures, so history starts on a computer when it first fetches.

### The later change wins

When two computers change the same keyword or draft, the later change is kept, and removing something counts as a change. What counts is when a change was made, not when it was synced: an edit made on Monday on a laptop that syncs again on Friday does not beat one made on Wednesday elsewhere.

### Safeguards

Before a sync removes or overwrites anything, the database is copied aside, and the last five days’ copies are kept. A file that is missing or still downloading never removes anything, a change from a clock that runs ahead waits until its time has come, and a computer set up from a copy of another gets a file of its own.

### What leaves your computer

That setup goes only to the folder you choose, under your own account with that service. Nothing is uploaded to asorocket.

**Requires:** asorocket Studio, and a folder in iCloud Drive, Dropbox or another synced folder that each computer can reach.
