# Account & cloud sync

> When you actually need to sign in, and what it unlocks — multi-device sync, sharing, more AI quota.

Magic Resume **works without signing in** — building resumes and exporting PDFs needs no account. So when should you register?

## Do you even need to sign in?

<CardGroup cols={2}>
  <Card title="Signed out (local mode)" icon="laptop">
    Your resume lives only in **this browser**, visible only to you. Great for making one quickly. Downside: switch devices or clear the cache and it's gone; **no AI**, no sharing, no multi-device.
  </Card>

  <Card title="Signed in (cloud mode)" icon="cloud">
    Resumes are stored in the cloud, and it unlocks **AI features** (AI Lab, AI PDF import): plus **multi-device sync**, automatic backup of every version, and **share links** to collect comments.
  </Card>

## How to sign up / in

<Steps>
  <Step title="Open sign-in">
    Click the account avatar at the top right (or go to the sign-in page). You'll see **Log in to Magic Resume**. First time? Click **Sign up**.
  </Step>

  <Step title="Choose a method">
    Three options, pick any:

    * **Continue with Google**
    * **Continue with GitHub**
    * **Continue with email** (enter your email → get a code / set a password)

    <Tip>Google / GitHub is the easiest — one click, no new password to remember.</Tip>
  </Step>

  <Step title="Turn on cloud sync">
    After signing in, **cloud sync is off by default** — whether your data goes to the cloud is your call. Go to **Settings → Cloud Sync** and turn on **Enable cloud sync** (you'll see a short data notice first). From then on, changes on this device sync to the cloud automatically.
  </Step>
</Steps>

<Note>
  **Already made resumes locally — will signing in lose them?** No. Your existing local resumes stay; once cloud sync is on, they're synced up to the cloud.
</Note>

## What else is in your account

Click the account avatar to find: **Profile**, **Settings**, **Language** switch, and **Sign out** — plus your **Subscription** usage (current plan, how many AI runs are left this period). To unlock all AI capabilities you can **Upgrade to Pro** (see Pricing; ⚠️ some capabilities may be marked "Coming soon").

<Warning>
  Cloud mode needs the backend online. On the official [magic-resume.cn](https://magic-resume.cn) everything is ready; if you **self-hosted**, cloud sync/AI require you to deploy the backend too — that's a technical task, see the [Developer Handbook](/en/introduction).
