Privacy
Maidian QR is designed around local browser processing. Your inputs are not uploaded to our servers, but a QR code is a scannable copy of that content—consider who may see it before sharing.
Generated locally, readable from the code
Input
Links, Wi-Fi passwords, contacts, locations, and events enter current page memory only.
Encode
Your browser encodes content directly into QR pixels—no short link or MiluLand redirect.
Share
Anyone who can see and scan the QR code may read its complete payload.
Current page memory
Form entries, encoded payloads, PNG previews, and color settings exist only in this page's JavaScript memory. Refresh or close the page to clear them; Maidian cannot view or recover them. The interface does not automatically save Wi-Fi passwords, contacts, phone numbers, locations, or calendar details.
A QR code is not a secret container
PNG, SVG, and printed copies all carry the encoded content. Maidian cannot expire, revoke, or remotely edit a static QR code. Share Wi-Fi passwords or private contact details only with trusted recipients, and change them at the source if exposed.
Downloads and scan tracking
PNG, SVG, and VCF, ICS, or TXT payload files are generated and downloaded by your browser only after you click; they are not automatically sent back. Maidian does not record who scans, when, or where, but a destination site, app, or network may log visits under its own policies.
Local preferences and favorites
Language, theme, and high-contrast preferences are stored in your browser. These display preferences and up to 16 favorite tool IDs also use .miluland.com domain cookies so same-domain pages stay consistent. Favorites never contain inputs, files, or results, can be cleared from the MiluLand tool directory, and are not intentionally uploaded.
Advertising and third parties
This site uses Google AdSense Auto Ads. Depending on your consent, Google may use cookies or similar technologies to serve and measure ads. You can manage these choices in Google's privacy settings.
Contact
This tool is maintained by MiluLand. To report a privacy issue, use the contact page and do not email Wi-Fi passwords or private QR codes.
Optional analytics
This site loads Google Analytics only after your explicit permission to measure visits to tool and information pages. File names, file contents, tool inputs, search terms, QR payloads, URL parameters, and results are excluded. Google's enhanced measurement is off.
Your choice is saved in a .miluland.com cookie for 180 days and shared by MiluLand pages with analytics enabled. Use ‘Analytics choices’ at the bottom of the page to decline or withdraw permission; withdrawal disables measurement and clears accessible GA cookies. Browser GPC and Do Not Track keep analytics off. Advertising has separate Google consent settings.
