Privacy policy

What we collect

• Your email address, for sign-in and to send you the codes you save and account messages.
• The QR codes you create: the destination links, any custom styling, and the codes' settings.
• Basic profile info from your sign-in provider: your name and profile picture, if they share them.
• Scan data for your codes: timestamps, an approximate region derived from the visitor's IP address, and the browser or device type.
• Standard server logs: IP address, browser, and timestamps for requests to the site.
• Error telemetry, so we can find and fix bugs.

Signing in

You sign in with Google, Apple, Facebook, GitHub, or Microsoft. We use these only to verify who you are. From whichever provider you choose, we receive your email address (used to identify your account and send you account messages), and, if the provider shares them, your name and profile picture (shown in your account). That is all we request. We never ask for access to your Gmail, Drive, Calendar, contacts, files, photos, or anything beyond your name, email, and profile picture.

We do not sell this information. We do not share it with third parties for their advertising. We do not use it to train AI models.

If you signed in with Google, TangoQR's use of information received from Google APIs follows the Google API Services User Data Policy, including its Limited Use requirements.

You can disconnect TangoQR from your provider at any time: Google, Apple, Facebook, GitHub, Microsoft.

What we share

When someone scans one of your codes, they reach the destination you set. The companies that help us run TangoQR handle data on our behalf under their own terms: our hosting and database provider, our email provider, our payment processor, our error-monitoring provider, and our content-delivery network. We do not sell your data, and we do not run third-party advertising trackers.

Cookies

We use first-party cookies to keep you signed in and to remember basic product state. We do not use third-party advertising cookies.

Your choices

You can delete your account anytime from your profile page, or contact us and we'll take care of it. Deleting your account erases your personal data and cancels any active subscription. Your QR codes keep redirecting, so anything you have already printed stays working. If you signed in with an outside provider, you can also revoke our access from that provider's settings (see the links above).

Email communications

When you create an account, you'll receive transactional emails (login codes, billing, account information, material service changes) and occasional product updates about TangoQR. You can opt out of product updates at any time using the unsubscribe link in any email or from your account settings. Transactional emails are required to use the service and cannot be opted out of while your account is active. We do not share your email address with third parties for their own marketing, and we do not use your email to market other products in the Middlefield General Services portfolio without your separate explicit consent.

Children's data

The service is not intended for anyone under 13 (or 16 in the EU). We do not knowingly collect data from children.

Where we operate

We operate from the United States. By using the service you acknowledge your data is processed in the US.
