Privacy Policy

Effective date: September 26, 2026

Seungwon Choo ("we") operates the pricetag Chrome extension and the pricetag website (the "Service").

1. In short

The extension does not collect information that identifies you. There is no sign-up or login, and it does not collect the pages you visit.
The website collects your email address only if you ask to be notified about Pro.

Information	How it is used	Where it goes
The price text you select on a web page	Read on your device to find the currency and amount	Never sent anywhere
The two currency codes to convert between (e.g. USD, KRW)	Used to look up the exchange rate. The amount is never sent	The Frankfurter rate server (`api.frankfurter.dev`)
Your currency and favorite currencies	Used to remember your settings	Chrome’s browser storage. If Chrome sync is on, it may sync to your other devices through your Google account

The extension runs on all websites so you can select a price on any store, but it reads only the text you select.
The rate server may receive standard connection data (such as your IP address) when handling a request, under its own policies. We do not receive or keep this data.
We do not sell the information the extension handles, use it for advertising, or use it for anything other than providing the Service. The use of information by pricetag complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.

Information	Purpose	Kept until
Email address, language of the page you signed up on (Korean/English)	Sending pricetag news such as the Pro launch	You unsubscribe or ask us to delete it. Deleted promptly if the Service ends

Signing up is optional. You can use the entire extension without it; the only effect of not signing up is that you will not receive our emails.
After you sign up we send a confirmation email, and you are subscribed only after clicking its link.
Our email provider (Mailchimp) may record signup and confirmation times, IP address, and whether emails are opened.

The website stores your theme (light/dark) and language choice only in your browser (local storage). It is never sent to us.
The website uses no analytics tools and no advertising cookies.
Our hosting provider (GitHub Pages) may keep access logs (such as IP addresses) to run the service.

We use the following provider to send emails, which involves transferring your information outside Korea.

Recipient	The Rocket Science Group LLC (Intuit Mailchimp)
Country	United States
Information	Email address, signup language, signup and confirmation records
When and how	Sent over the internet when you sign up
Purpose	Storing the subscriber list and sending emails
Retention	Same as section 3

If you do not want your information transferred, simply do not sign up. It does not affect your use of the extension.

You may ask to access, correct, delete, or stop the processing of your information at any time.
Every email has an unsubscribe link that takes effect immediately.
For any other request, contact us below and we will respond promptly.

When the retention period ends or you ask us to delete your information, we delete it from Mailchimp promptly.

Our Mailchimp account is protected with a strong password and two-step verification.
Only the operator can access personal information.

Notifications are intended for people aged 14 and over. We do not knowingly collect information from children under 14.

If this policy changes, we will post the changes and the new effective date on the website.
