# How to Upgrade, Downgrade, or Cancel Sinosend Plan

> Upgrade or downgrade your Sinosend plan at any time. Upgrades take effect immediately; downgrades apply at the end of your billing cycle.

You can change your Sinosend plan at any time — no hoops to jump through. Upgrades are instant, downgrades take effect at the end of your current billing period, and cancellation is straightforward with no data loss surprises.

## Upgrade your plan

Upgrading gives you immediate access to higher transfer limits, more storage, additional team seats, and extra data regions.

<Steps>
  <Step title="Open Billing Settings">
    Log in to your Sinosend account, click your avatar in the top-right corner, and select **Account Settings**. Then click **Billing** in the left sidebar.
  </Step>

  <Step title="Click Upgrade Plan">
    Under **Current Plan**, click **Change Plan**. A plan comparison modal appears showing Personal, Pro, and Business options.
  </Step>

  <Step title="Select your new plan">
    Click **Select** on the plan you want to upgrade to. Review the pricing summary, including the prorated charge for the remainder of your current billing period.
  </Step>

  <Step title="Confirm the upgrade">
    Click **Confirm Upgrade**. Your new plan activates immediately. A receipt for the prorated charge is sent to your billing email.

    <Note>
      When you upgrade mid-cycle, Sinosend calculates a **prorated credit** for the unused days on your current plan and applies it to the cost of the new plan. You only pay for the difference.
    </Note>
  </Step>
</Steps>

<Tip>
  After upgrading to **Business**, contact [Sinosend support](https://sinosend.com/support) to set up your custom subdomain. The process requires a DNS change and typically completes within a few hours.
</Tip>

## Downgrade your plan

Downgrading reduces your plan limits at the end of your current billing period. You keep all your current features until then.

<Steps>
  <Step title="Open Billing Settings">
    Go to **Account Settings → Billing** and click **Change Plan**.
  </Step>

  <Step title="Select a lower plan">
    Click **Select** on the plan you want to move to. A confirmation message shows the date your new plan takes effect — this is the last day of your current billing cycle.
  </Step>

  <Step title="Confirm the downgrade">
    Click **Confirm Downgrade**. Your current plan remains active until the billing cycle ends. You won't be charged the lower rate until your next renewal date.

    <Warning>
      If your current storage usage exceeds the new plan's limit, you'll need to delete files before the downgrade takes effect. Sinosend sends an email reminder 7 days before the change if your usage is over the new limit.
    </Warning>
  </Step>
</Steps>

## Annual vs. monthly billing

You can switch between annual and monthly billing at any time from **Account Settings → Billing → Billing Frequency**.

| Billing cycle | Price example (Pro)             | Best for                                       |
| ------------- | ------------------------------- | ---------------------------------------------- |
| **Annual**    | $19/month (billed as $228/year) | Teams with predictable, ongoing transfer needs |
| **Monthly**   | Slightly higher per-month rate  | Seasonal or project-based usage                |

<Tip>
  Annual billing is the better value if you use Sinosend year-round. Switch to annual billing any time to lock in the lower rate — the change takes effect at your next renewal.
</Tip>

## Cancel your subscription

Cancelling stops future charges and moves your account to the **Free tier** at the end of your current billing period.

<Steps>
  <Step title="Open Billing Settings">
    Go to **Account Settings → Billing** and scroll to the bottom of the page.
  </Step>

  <Step title="Click Cancel Subscription">
    Click **Cancel Subscription** and select a cancellation reason from the dropdown. Your feedback helps Sinosend improve the product.
  </Step>

  <Step title="Confirm cancellation">
    Click **Confirm Cancellation**. You'll receive a confirmation email. Your paid plan remains active until the end of the current billing period — you won't be charged again.
  </Step>
</Steps>

### What happens after cancellation

| Item                 | What happens                                                                               |
| -------------------- | ------------------------------------------------------------------------------------------ |
| **Plan access**      | Paid features remain active until the billing period ends, then revert to the Free tier.   |
| **Stored files**     | Files are retained for **30 days** after reversion to Free tier, then permanently deleted. |
| **Transfer history** | Your delivery history and tracking data remain visible in your dashboard.                  |
| **Account**          | Your account stays open on the Free tier. You can resubscribe at any time.                 |

<Warning>
  Download any files you want to keep before the 30-day retention window closes. Sinosend sends a reminder email 7 days before permanent deletion.
</Warning>

## Reactivate a cancelled plan

If you cancelled and want to resubscribe, go to **Account Settings → Billing** and click **Reactivate Subscription**. Choose a plan and billing cycle — your new plan activates immediately.

<Tip>
  If you're cancelling because of cost, consider switching to annual billing for a lower monthly rate, or downgrading to the Free tier instead of cancelling entirely.
