Weather-Kok ("the App") values your privacy and is committed to protecting your personal information in compliance with applicable laws.
This Privacy Policy explains what information we collect, how we use it, and the measures we take to protect it.

Weather-Kok uses your device's location to provide weather and air quality information based on your current position.
- Location data is used temporarily only when fetching weather API data.
- Location data is never stored on our servers.
- Location is accessed only while you are using the app — we do not track location in the background.
- You can use the app without granting location permission by manually setting your preferred location.
1-2. Anonymous User Identifier
We generate and store an anonymous user ID to provide app functionality and improve our services.
This identifier is a random value that cannot be used to identify you personally.

Appendix. Website Cookies and Visit Analytics
Unlike the other sections, which describe the app, this section applies only to the website (the domain serving this page).
- What we collect — pages visited, referral information (UTM parameters), approximate location (country and city level), device and browser type, screen size, and whether a store link was clicked. The identifier stored in cookies is a browser-level online identifier and may qualify as personal information; however, we do not collect your name, email address, phone number, or any other directly identifying information, and we do not use this identifier to single out any individual.
- Why we collect it — solely to understand how visitors reach this site so that we can improve it. It is never used for advertising or profiling.
- Tool and cookies — Google Analytics 4 (Google LLC), which stores cookies (
_ga, _ga_*) in your browser to distinguish browsers. These cookies last for up to 2 years, and you can delete them at any time using your browser's cookie controls.
- Retention — Google Analytics event data is retained for up to 14 months and then deleted automatically. Your consent choice and referral values are stored only in your own browser and are never sent to our servers.
- Outsourced processing and international transfer — the statistics above are processed by a processor acting within the scope of our instructions, which constitutes an overseas transfer for outsourced processing; the following is disclosed under Article 28-8 of the Korean Personal Information Protection Act. Recipient: Google LLC (1600 Amphitheatre Parkway, Mountain View, CA, USA; contact via the Google Privacy Policy). Country of transfer: the United States. Timing and method of transfer: transmitted over the network via cookies from time to time as you use the website. Items transferred: as listed under "What we collect" above. Recipient's purpose of use: generating and analyzing visit statistics for this website, within the scope of our instructions. Recipient's retention period: as stated under "Retention" above. You may refuse this transfer as described under "How to consent, refuse, or withdraw" below, with no disadvantage whatsoever in using the website. We do not provide the data to any other third party.
- How to consent, refuse, or withdraw — choose Decline on the banner shown on your first visit and Google Analytics is never loaded; the site remains fully usable. Even after accepting, you can withdraw your consent at any time via Cookie settings; when you withdraw (decline), the related cookies are deleted. As an additional option, you can also remove the cookies by clearing cookies and site data in your browser.
The referral tags (UTM) appended to store buttons do not identify you, are held only for the current browser session, and work regardless of your cookie choice.
