BIMFactory Co., Ltd. ("Company") uses cookies and similar technologies when you use "Forecast AI" (the "Service") to process behavioral information. This Cookie Policy explains which cookies we use, for what purposes, and how you can refuse or block them.
This Policy supplements the Company's Privacy Policy. If any conflict arises, the Privacy Policy prevails.
1. What Are Cookies?
Cookies are small text files stored on your browser when you visit a website. They identify the browser, device, or session to keep you signed in, remember preferences, and analyze usage.
In addition to cookies, we use similar technologies:
- LocalStorage / SessionStorage — stores user preferences such as language and theme

| Advertising | Not currently used (a separate consent mechanism will be provided if introduced) |

3.4 Advertising
The Company does not currently install advertising cookies on its website. Conversion-tracking and retargeting tools such as Google Ads tags and the Meta Pixel are not in use.
If advertising cookies are introduced in the future, they will constitute behavioral information, and the Company will amend this Policy and put in place a separate, category-level consent mechanism (a cookie consent banner) before activating them.
Where the mobile app serves ads, advertising identifiers (AAID/IDFA) are used instead of cookies; see Section 6 for how to opt out.
4. Your Choices Regarding Cookies
The Company does not currently operate a cookie consent banner. This is because no advertising cookies are used and the cookies in use are limited to those necessary to run the Service and to anonymous analytics. You can block any non-essential category at any time.
4.1 Blocking analytics cookies
- Google Analytics 4 — install Google's opt-out browser add-on to stop GA4 collection on all sites.
- Microsoft Clarity — enable your browser's tracking prevention, or block cookies as described in Section 5.
- General — turning on "Block third-party cookies" in your browser prevents analytics cookies from being stored.
4.2 Blocking functional cookies
You may delete or block the language and theme cookies. Your preferences will then reset on each visit.
4.3 Deleting cookies already stored
Follow the browser-specific instructions in Section 5.
4.4 If advertising cookies are introduced
Should the Company introduce advertising cookies, a consent banner will let you accept, reject and withdraw consent by category, and no advertising cookie will be stored before consent is given. This Policy will be amended and announced before the change takes effect.
5. How to Block Cookies by Browser
You can block cookies directly in your browser. Blocking all cookies, including necessary ones, may restrict sign-in and other features.

- Edge — Settings → Cookies and site permissions → Manage and delete cookies and site data
