# Sinosend FAQ: Plans, China Transfers, Tracking, Security

> Answers to the most common Sinosend questions — free plan limits, sending files to China, tracking deliveries, security, and billing.

Find quick answers to the questions Sinosend users ask most — covering everything from how the platform works and what's included in the free plan, to sending files into China, tracking deliveries in real time, and keeping your documents secure.

## General

<AccordionGroup>
  <Accordion title="What is Sinosend?">
    Sinosend is a document delivery and file transfer platform built for global trade. It lets you send large files to recipients anywhere in the world — including mainland China — with real-time delivery tracking, geolocation intelligence, and enterprise-grade security.

    Unlike general-purpose cloud storage tools, Sinosend is purpose-built for *sending*: every transfer comes with a tracked delivery link, open notifications, and access controls you can manage after the file has left your hands.

    Notable customers include Hapag-Lloyd, H\&M, Haier, Pizza Hut, Tata, and Ogilvy.
  </Accordion>

  <Accordion title="Is there a free plan?">
    Yes. The Sinosend free plan includes:

    * **5 GB** per transfer
    * **10 GB** total storage
    * Up to **6 recipients** per transfer
    * **No expiry** — your transfers never disappear automatically
    * **Geolocation metadata** — see where recipients open your files

    No credit card is required to sign up. [Create your free account](https://app.sinosend.com) and start sending in minutes.
  </Accordion>

  <Accordion title="Do recipients need a Sinosend account?">
    No. Recipients receive a secure download link by email — they click it and download the file directly in their browser. They never need to create an account or install any software.
  </Accordion>

  <Accordion title="What file types does Sinosend support?">
    Sinosend supports all file types — PDFs, CAD files, videos, images, ZIP archives, spreadsheets, presentations, and more. There are no restrictions on file format.
  </Accordion>

  <Accordion title="How large can my transfers be?">
    Transfer size limits depend on your plan:

    | Plan     | Max transfer size | Total storage |
    | -------- | ----------------- | ------------- |
    | Free     | 5 GB              | 10 GB         |
    | Personal | 10 GB             | 100 GB        |
    | Pro      | 25 GB             | 500 GB        |
    | Business | 100 GB            | 1 TB          |

    <Tip>
      If you regularly send large video files, technical drawings, or bulk data exports, the Pro or Business plan gives you the headroom you need without splitting transfers.
    </Tip>

## Sending

<AccordionGroup>
  <Accordion title="How many recipients can I add to a transfer?">
    Recipient limits by plan:

    | Plan     | Max recipients per transfer |
    | -------- | --------------------------- |
    | Free     | 6                           |
    | Personal | 20                          |
    | Pro      | 50                          |
    | Business | 100                         |

    Each recipient gets their own tracked delivery link, so you can see exactly who opened the file and when.
  </Accordion>

  <Accordion title="Can I send files to someone in China?">
    Yes — and this is one of Sinosend's core strengths. When creating a transfer, select either the **APAC Hong Kong** or **Mainland China (Shanghai)** data region to route your transfer through infrastructure optimised for Chinese networks.

    <Tip>
      If your recipient is inside mainland China, choose the **Mainland China (Shanghai)** region for the fastest download speeds. Hong Kong works well for recipients in Hong Kong and surrounding areas.
    </Tip>

    This routing bypasses the cross-border network congestion that typically causes timeouts and failures when sending large files into China using tools like WeTransfer or Dropbox.
  </Accordion>

  <Accordion title="Can I password-protect a transfer?">
    Yes. When creating a transfer, enable the **Password protection** option and set a password. Recipients will be prompted to enter the password before they can view or download any files. Share the password with your recipient through a separate channel — for example, by phone or messaging app.
  </Accordion>

  <Accordion title="Can I change the expiry date after sending?">
    Yes. Sinosend's **Dynamic File Management** lets you extend or adjust the expiry date of any transfer after it has been sent. Open the transfer from your dashboard, navigate to **Expiry**, and update the date. The recipient's existing link will automatically reflect the new expiry — no need to resend.
  </Accordion>

  <Accordion title="Can I update or replace a file after sending?">
    Yes. You can replace a file in an existing transfer at any time. The recipient's download link stays exactly the same — they'll simply download the updated version next time they click it. This is useful for sending revised documents without having to contact recipients again.
  </Accordion>
</AccordionGroup>

## Tracking & delivery

<AccordionGroup>
  <Accordion title="Will I know when someone opens my file?">
    Yes. Sinosend sends you a real-time **email notification** the moment a recipient opens their delivery link. You can also monitor all activity from the **dashboard** — each transfer shows a full timeline of opens, downloads, and reminders for every recipient.
  </Accordion>

  <Accordion title="Can I see where the recipient is located when they open the file?">
    Yes. Sinosend's **delivery intelligence** includes a geolocation map showing the approximate location from which each recipient accessed the file. This is available on all plans, including the free tier.

    <Note>
      Geolocation is based on the recipient's IP address at the time of access. Location accuracy varies by network type and country.
    </Note>
  </Accordion>

  <Accordion title="What if the recipient doesn't open the file?">
    Sinosend automatically sends reminders to recipients who haven't opened their transfer. You can also manually trigger a resend from the dashboard by opening the transfer, selecting the recipient, and choosing **Resend notification**. If the email address turns out to be wrong, you can update it and resend from the same screen.
  </Accordion>

  <Accordion title="Can I revoke access to a specific recipient?">
    Yes. To revoke a single recipient's access without affecting others:

    1. Open the transfer from your dashboard
    2. Go to the **Recipients** tab
    3. Find the recipient and select **Revoke**

    Their link is immediately invalidated. Other recipients' links remain active.
  </Accordion>
</AccordionGroup>

## Billing

<AccordionGroup>
  <Accordion title="Is there a free trial for paid plans?">
    Yes. Every paid plan comes with a **7-day free trial** — no credit card required. You get full access to all features on the plan you choose. If you don't upgrade before the trial ends, your account automatically reverts to the free tier.
  </Accordion>

  <Accordion title="Can I cancel my subscription at any time?">
    Yes. You can cancel at any time from your account settings. Your plan remains active until the end of the current billing period, then your account reverts to the free tier. You never lose access to files already sent — they remain in your dashboard on free plan limits.
  </Accordion>

  <Accordion title="Are there discounts for annual billing?">
    Yes. The prices listed — Personal at $9/mo, Pro at $19/mo, and Business at \$49/mo — reflect **annual billing**. You can also choose monthly billing at a slightly higher per-month rate. Annual billing is the best value if you use Sinosend regularly throughout the year.
  </Accordion>
</AccordionGroup>

## Security

<AccordionGroup>
  <Accordion title="How are my files encrypted?">
    Sinosend protects your files at every stage:

    * **At rest** — files are encrypted using **AES-256**, the same standard used by financial institutions and governments worldwide
    * **In transit** — all transfers use **TLS 1.2 or higher** to prevent interception during upload and download

    Access controls, password protection, and per-recipient revocation give you additional layers of security on top of encryption.
  </Accordion>

  <Accordion title="Is Sinosend GDPR compliant?">
    Yes. Sinosend is GDPR compliant. If you need to keep data within the European Union, select the **EU data region** when creating a transfer or in your account settings. A **Data Processing Agreement (DPA)** is available on request — contact the support team at [sinosend.com/support](https://sinosend.com/support) to request one.
