Website privacy and analytics policy

Data when you visit

Umami analytics can be enabled on the public site; previews and check builds do not send statistics. Google Analytics 4 loads only after you accept the cookie notice. Before a choice, or after declining, the website neither loads GA nor sends data to Google.

After acceptance, GA sets _ga cookies to recognize repeat visits and receives viewed pages, referrers, device/browser type, approximate IP-based location and clicks to our products or contact channels. We do not send entered text, your email or phone number. Potentially sensitive URL parameters are removed before transmission. Advertising features are not enabled. Google processes this data under its privacy policy and may process it outside Vietnam; analytics is shared with /dich/app/.

Your choice is saved in browser storage and can be changed through Cookie settings in the footer. Declining clears GA cookies. We do not embed Facebook Pixel. Fonts come from this website. Infrastructure still handles IP and similar technical information to deliver pages.

Information sent through contact channels

We receive only what you choose to send by Zalo, phone or email: contact details, business needs and sample files. Use it to reply, schedule and prepare discovery and send a proposal. We do not sell, rent or advertise without consent. Zalo and email providers have their own terms. Retention follows the purpose of the exchange and work; deletion can be requested, with required retained records explained. Account, purchase and interpretation-room data is covered in the shared privacy policy.

Your rights and updates

Email admin@vantocso.com for an explanation, access, correction or deletion. We confirm receipt and explain the outcome, including any retention required by law. The Vietnamese original cites Personal Data Protection Law 91/2025/QH15, effective 1 January 2026. Changes to collection or processing are reflected in this notice and the shared privacy policy with an updated date.
