1. Introduction
At Mercari, we use cookies and similar tracking technologies to ensure our platform functions securely, to understand how you interact with our services, and to provide you with relevant content and advertisements.
This policy explains what these technologies are, how we use them, and how you can control them. For a comprehensive view of how we handle your personal data, please see our Global Privacy Policy.
2. Tracking Technologies We Use
We use cookies and similar tools (such as pixels, SDKs, and local browser storage) to recognize you and collect information about your visit. These can be session-based (cleared when you close your browser) or persistent (remaining on your device until they expire or are manually cleared).
- Cookies & Storage: Small files or data stored on your device that help us remember your login and preferences. These may be "first-party" (set by us) or "third-party" (set by our partners like Google or Meta).
- Pixels & Tags: Tiny scripts used to understand how you interact with our site and emails, helping us measure ad performance.
- Persistent Identifiers: Technologies like ETags that help us recognize returning visitors to provide a consistent experience.
3. Categories of Tracking Technologies
We group the tracking technologies we use into four categories:
-
Required
These cookies are essential for the site to function, enabling core features like secure log-ins and order processing. They cannot be disabled. -
Functional
These cookies allow our service to provide enhanced functionality and personalization, such as remembering your preferences and display settings. If you disable them, some of the services may not function properly. -
Analytics
These cookies allow us to analyze how our service is used so that we can measure and improve our performance. If you disable them, we will not be able to provide you with an optimized experience. -
Targeting
We use these Cookies to deliver personalized ads and recommendations tailored to your interests. To provide this experience, we share data (such as registered email addresses and advertising IDs) with our advertising partners, including Google and Meta, to show you relevant content both on and off Mercari. If you disable them, you will still see ads, but they will no longer be personalized based on your activity or history with us.
Note for California Residents: The use of Targeting cookies may be classified as the "sale" or "sharing" of personal information under the CCPA/CPRA. You have the right to opt-out of this at any time.
4. Your Choices
You can control how your data is tracked.
a. Consent Management
You can modify your preferences for Functional, Analytics, and Targeting trackers at any time. Access it via "Privacy Preferences" in the website footer or in your account settings on the mobile app.
b. Global Privacy Control (GPC)
We recognize and honor Global Privacy Control (GPC) signals. If your browser sends a GPC signal, we will automatically treat it as a request to opt-out of the "sale" or "sharing" of your personal information for targeted advertising.
c. "Do Not Sell or Share My Personal Information"
Residents of California and other US states with applicable privacy laws can exercise their right to opt-out of data sharing for cross-context behavioral advertising by following the procedures outlined in the "Do Not Sell or Share My Personal Information". We do not "sell" personal information to third parties for monetary consideration.
d. Browser Controls
You can block or delete cookies and clear your cache (which also removes ETags) through your browser settings:
| Browser | Settings Location |
|---|---|
| Google Chrome | Settings > Privacy & Security > Cookies |
| Mozilla Firefox | Options > Privacy & Security |
| Safari | Preferences > Privacy |
| Microsoft Edge | Settings > Privacy, Search & Services |
5. Data Retention
We retain tracker data only as long as necessary:
- Session data is deleted immediately after you close your session.
- Persistent data (like persistent cookies or Local Storage) remains on your device until it reaches its expiration date or you manually clear it.
6. Updates to This Policy
We'll update this policy from time to time. If we make significant changes, we'll let you know through our consent banner or by updating the date at the top of this page.
