Privacy Policy
This policy explains how Guangzhou Mio International Trade Co., Ltd. ("we", "us") handles information in connection with MIO ERP, a Windows desktop application for cross-border marketplace sellers, the MIO account you sign in with, and the websites under download.miopacks.com and license.miopacks.com.
1. The short version
- MIO ERP runs on your own computer and works on a local database there.
- Like a messaging app, your business data follows your MIO account: an encrypted copy is kept with your account on our server so you can sign in on another computer and get it back.
- We do not ask for buyer names, addresses or phone numbers from any marketplace.
- We never sell, rent or share your data, and we do not use it for anything other than giving it back to you.
2. Data processed on your computer
When you use MIO ERP, the application stores the following in a local database on your device: your stores and marketplaces, orders and order items read from the marketplaces you authorize, product and listing information, costs and fees you enter or import, exchange rates, and your settings. Marketplace authorization tokens and application credentials are encrypted at rest in a local vault that is unlocked with a passphrase only you know. Access to the application is protected by your own login.
3. Data from Amazon and other marketplaces
MIO ERP connects to a marketplace only after you authorize it in that marketplace's own seller portal. For Amazon, MIO ERP uses the Selling Partner API for your own seller account: it reads orders and order items (without buyer personally identifiable information), the marketplaces you sell in, listings, inventory, fees, settlements and reports, and it creates or updates your own listings, prices and stock and confirms shipments only after you approve each change inside MIO ERP. MIO ERP does not create orders. You can revoke access at any time in Seller Central (Apps and Services → Manage Your Apps); MIO ERP then stops using your Amazon data, and you can delete it inside the application.
We handle Amazon information in line with the Amazon Services API Developer Agreement, Acceptable Use Policy and Data Protection Policy.
4. Data we keep on our servers
Your MIO account. Your email address, a salted hash of your password (never the password itself), your plan, expiry and device limit, a hashed identifier and the name of each computer you sign in on, and an audit log of account changes. License keys and sign-in tokens are stored only as hashes.
Your account copy. While you are signed in, MIO ERP regularly uploads a copy of its business database (stores, products, orders, costs, settings — including Amazon information described in section 3) and of your encrypted vault, so you can restore it on another computer. The copy is transferred over HTTPS and stored encrypted (AES-256-GCM) on our server. Marketplace tokens inside it remain encrypted with your own vault passphrase, which we never receive. We keep only the latest three copies per account.
Authorization hand-off. When you authorize MIO ERP in a marketplace, the marketplace redirects your browser to our redirect page with a one-time authorization code and a random state value. We keep these in memory only until your MIO ERP application collects them, and for no longer than 5 minutes, then delete them.
Website visits. Our web server keeps standard technical logs (IP address, time, requested page, browser type) for security and troubleshooting. We do not use advertising or tracking cookies.
5. How we use information
We use the information above only to provide and secure MIO ERP: to run your account and its device limit, to keep and give back your account copy, to complete marketplace authorizations, to answer your support requests and to protect our services against abuse. We do not read, analyse or mine the contents of your account copy.
6. Sharing
We do not sell, rent or trade any information. Our only processor is our hosting provider (Google Cloud), which runs our servers on our behalf. If you choose to set up an AI model provider inside MIO ERP, the application sends that provider only the product data needed for the AI task you start, never buyer data; that provider is your own choice and account. We disclose information otherwise only where required by law.
7. Retention and deletion
Data on your computer stays under your control until you delete it or uninstall MIO ERP. On our server we keep the latest three account copies; older copies are deleted automatically when a new one arrives. You can ask us at any time to delete your account and all its copies; we do so within 30 days. Authorization hand-off data is deleted within 5 minutes. Account and license records are kept while your account exists and as long as needed for accounting and legal obligations afterwards. Web server logs are kept for a limited period for security purposes.
8. Security
We use HTTPS for all our websites and services, encrypt account copies at rest on our server, keep marketplace credentials encrypted with your own passphrase, store passwords and license secrets only as hashes, allow only one computer at a time to write to an account copy, restrict server access to authorized personnel with key-based sign-in, and keep our software up to date. If we become aware of a security incident affecting your information we will notify you and, where required, the relevant marketplace (for Amazon, security@amazon.com within 24 hours) without undue delay.
9. Your choices
You can stop MIO ERP from reading marketplace data at any time by turning off marketplace reading in the application or revoking its authorization in the marketplace's seller portal. You can sign out of your MIO account on a computer at any time. You can ask us to access, correct or delete the information we hold about you by contacting us.
10. Where our servers are
Our account, licensing and authorization servers, including account copies, are hosted on Google Cloud in Hong Kong.
11. Children
MIO ERP is a business tool and is not intended for children.
12. Changes
We will post any changes to this policy on this page and update the effective date above.
