Privacy policy

01. Who is responsible for your data

VIMGROUP Investment Joint Stock Company (business registration no. 0108238230, No. 4A, Lane 445, Nguyen Khang Street, Cau Giay Ward, Hanoi, Vietnam) is the controller and processor of personal data when you use the Myna Happy shop.

02. What we collect

• Email, plus your name and phone number when you order, create an account or fill in a form.
• Orders and payment status: order number, amount, time, status. We don't store card data. PayPal handles card details.
• A hash of your IP address, to count referral link clicks and prevent fraud. We don't keep the raw IP for this.
• Cookies and browser storage (see Cookies below).
• The messages you send to the chat assistant on the site.
• What you add to your account yourself: your birthday (to give birthday points), and a payout account if you're an affiliate.

03. Why we use it, and on what basis

• Contract: delivering files, confirming payment, sending download links, order support, managing your account, points and commission.
• Your consent: emails with news, printing tips and offers. You opt in when you sign up and can opt out at any time.
• Legitimate interest: preventing fraud (for example buying through your own referral link, or abusing points), keeping the system safe, improving the site with anonymous numbers.
• Legal obligation: keeping accounting records, issuing invoices, answering authorities when legally required.

04. Cookies and browser storage

• mh_mem: keeps you logged in to your member account.
• mh_ref: remembers the referral link you clicked, for up to 30 days, so the referrer can be credited.
• Light/Dark theme: your choice is stored in the browser's localStorage and never sent to our servers.

We don't use advertising cookies or third-party trackers.

05. Who processes data on our behalf

Data passes only through the services needed to run the shop, and they may only use it as we instruct:

• An email sending service.
• Web hosting and database services.
• Payment: our bank (for VietQR transfers) and PayPal.
• An AI assistant provider, which processes the messages you send to the assistant.

We never sell, rent or trade your personal data. Beyond these providers, we share it only when a competent authority requires it by law.

06. How long we keep it

• Orders and payment records: for as long as accounting and tax law require.
• Deleted accounts: we erase your name and phone number. Remaining order data is kept only for accounting, never for marketing.
• Newsletter email: until you unsubscribe.
• Assistant chats: for as long as needed to support you and improve the service.

07. Your rights and how to use them

You have the right to be informed, to access, correct, erase, restrict, object, and to withdraw consent. Most of it you can do yourself in your account page:

• Download my data: get a copy of what we hold about you.
• Edit profile: update your name, phone number and birthday.
• Unsubscribe: one tap, or the link at the bottom of any email.
• Delete account: erases your name and phone number as described under retention.

For anything else, contact email mynahappystore@gmail.com or phone +84 986 969 339. We reply within a few working days. You also have the right to complain to the competent data protection authority.

08. Withdrawing consent

You can withdraw your consent to marketing at any time, no reason needed. It doesn't affect processing already done, and it doesn't affect the files you bought.

09. How we protect it

Connections are encrypted (HTTPS). Paid files sit in private storage and open only through a time-limited download link. No system is perfectly safe, but we do our best.

10. Children

Parents and teachers buy on behalf of kids. We don't knowingly collect children's personal data. If you think your child has sent us information, contact us and we'll delete it.

11. If something goes wrong

If a data breach affects you, we'll act right away, notify the competent authority as the law requires, and tell you what happened and how to protect yourself.

12. Summary for international buyers (GDPR-style)

If you buy from outside Vietnam, you get the same set of rights wherever you live:

• Rights of access, rectification, erasure, restriction, objection and portability.
• Legal bases: contract, consent, legitimate interest and legal obligation, as above.
• We don't sell your data.
• You may lodge a complaint with the data protection authority where you live.

13. Changes to this policy

When the policy changes we update the version number at the bottom of the page. Important changes are announced by email or on the site.

14. Contact

For any personal data request: email mynahappystore@gmail.com or phone +84 986 969 339.
