Privacy Policy

Dokokoko (dokokoko.kr, the "Service") values the personal information of its users and complies with the Personal Information Protection Act (Republic of Korea) and other applicable laws and regulations. This Policy explains how user information is collected, used, and protected in the course of using the Service, including Japan parking lot search and fee simulation.

Effective date: October 19, 2026

Article 1 (Items of Personal Information Collected and Methods of Collection)

The Service can be used by anyone free of charge without signing up as a member, and collects only the minimum information necessary to provide the Service.

• Location information: When a user uses the "Current location" function, the latitude and longitude coordinates are temporarily used through the browser's location (Geolocation) function. These coordinates are used only for searching for nearby parking lots and are not stored on the server.
• Search terms: Addresses, place names, and Google Maps URLs entered by users are processed for coordinate conversion and parking lot search, and are not stored in association with any personally identifiable information.
• Parking lot report information: When the parking lot reporting function is used, we collect the content of the report, the Google Maps URL, and, only where the user wants a reply, an email address (optional).
• Travel itinerary information: Flights, schedules, notes, and the like entered in the itinerary function are stored only in the user's browser (local storage) and are not transmitted to the server.
• Automatically collected information: Service usage records, access logs, cookies, IP address, browser type, and operating system may be collected automatically.
• Browser extension: The Chrome extension "Dokokoko — Japan Parking Finder and Fee Simulator" is used without signing up and does not collect information that identifies individuals. When a user selects a place on Google Maps, the coordinates (latitude and longitude) and name of that place, and the entry and exit times the user entered for fee calculation, are transmitted to the Service's servers and used only for searching for nearby parking lots and calculating fees. This information is not stored in association with any user account or identifier. The extension reads only the address bar URL of the Google Maps page and does not access the page content or the user's Google account information.

Article 2 (Purposes of Collecting and Using Personal Information)

• Providing the Service: providing location-based parking lot search, fee simulation, map display, and travel itinerary management
• Handling reports: verifying and registering reported parking lot information and, at the reporter's request, replying with the result
• Improving the Service: analyzing usage statistics, identifying errors, and developing new features
• Displaying advertising: showing personalized or non-personalized advertising (see Article 6)
• Extension: searching for parking lots near a place selected on Google Maps and calculating fees

Article 3 (Retention and Use Period of Personal Information)

As a general rule, personal information is destroyed without delay once the purpose of its collection and use has been achieved.

• Email address collected with a report: destroyed after the report has been handled and a reply sent
• Website visit records under the Protection of Communications Secrets Act: 3 months
• Itinerary information stored in the browser: disappears immediately when the user deletes browser data (not kept on the server)

Article 4 (Provision to Third Parties and Outsourcing of Processing)

As a general rule, the Service does not provide users' personal information to outside parties. The following cases are exceptions.

• Where the user has given prior consent
• Where required under the provisions of law, or where an investigative agency requests it in accordance with the procedures prescribed by law

To operate the Service, processing is outsourced as follows, and some of the contractors are overseas businesses.

• Supabase Inc. (United States): database hosting (storing parking lot information, report content, and optionally entered email addresses). Data is stored in the Republic of Korea (Seoul) region.
• Vercel Inc. (United States): website hosting and access processing. Servers run in the Republic of Korea (Seoul) region, and access logs may be processed overseas as described in Article 4-2.

In addition, the following third-party services are integrated, and the privacy policy of each service may apply.

• Google Maps (map linking), Google AdSense (advertising), Google Analytics (usage statistics)
• OpenStreetMap Nominatim (converting addresses to coordinates: the search term entered is transmitted), OSRM (route search: coordinates are transmitted)

Article 4-2 (Overseas Transfer of Personal Information)

To provide the Service, personal information is processed and stored overseas as described below. This is disclosed pursuant to Article 28-8(1)(3) of the Personal Information Protection Act (Republic of Korea).

• Vercel Inc. (United States / privacy@vercel.com)
  Items transferred: access records such as IP address, access time, and browser and device information
  Country, timing and method: the United States and other countries where Vercel operates / when the Service is accessed / transmitted over the network
  Purpose and retention: website hosting and handling outages and security / until the outsourcing contract ends or Vercel's retention period expires
• Google LLC (United States / https://support.google.com/policies)
  Items transferred: cookie identifiers, IP address, visit records
  Country, timing and method: the United States / when the Service is accessed / sent from the browser to Google Analytics and Google AdSense
  Purpose and retention: visit statistics and ad serving / according to Google's retention policy and service settings
• OpenStreetMap Foundation (United Kingdom / privacy@osmfoundation.org)
  Items transferred: address search terms, IP address
  Country, timing and method: the United Kingdom and other countries where the Foundation operates / when an address search is made / sent from the browser to Nominatim
  Purpose and retention: converting addresses to coordinates / according to the Foundation's retention policy

How to refuse and its effect: Declining in the cookie notice or blocking cookies in your browser settings limits the transfer of information to Google for personalized advertising and analytics; non-personalized ads are shown instead. If you do not use address search, no information is transferred to the OpenStreetMap Foundation, and you can still find parking by moving the map or using the place list. The transfer of website access records is essential to providing the Service, so if you do not want it, please stop using the Service.

Article 5 (Procedures and Methods for Destroying Personal Information)

Information in the form of electronic files is deleted by technical means that make it irrecoverable. Information stored only in the browser disappears as soon as the user deletes the browser data.

Article 6 (Cookies and Advertising and Analytics Tools)

The Service uses cookies for the following purposes.

• Functional cookies: providing conveniences of the Service, such as maintaining search state
• Google Analytics: analyzing visit statistics. The information collected is used in a form that does not identify individuals.
• Google AdSense: Google and other third-party vendors may use cookies to serve ads based on a user's past visits.

Users can also opt out of personalized ads in Google Ad Settings, or refuse to store cookies in their browser settings (e.g., Chrome > Settings > Privacy and security > Cookies).

The browser extension does not display advertising and does not use analytics tools or tracking cookies.

Article 7 (Rights of Users and How to Exercise Them)

Users may withdraw the provision of information at any time by ceasing to use the Service or by deleting their browser's cookies and local storage. If you wish to access, correct, or delete the email address you entered when submitting a report, please make a request to the contact in Article 10. We will take action without delay.

• Access permissions to the database are kept to the minimum necessary.

Article 9 (Refusing the Installation and Operation of Automatic Information Collection Devices)

Through the web browser's option settings, users can allow all cookies, be asked for confirmation each time a cookie is stored, or refuse the storage of all cookies. However, if cookie storage is refused, use of some features may be restricted.
