Cookie and Site Storage Policy

Effective September 23, 2026

This Cookie and Site Storage Policy explains how Threeum Corporation (“Threeum,” “we,” “us,” or “our”) uses cookies and similar technologies on the public website at threeum.com (the “Site”). It identifies the storage controlled by the Site, explains technologies that may be used by our service providers, and describes the choices available to you. Please read it together with our Privacy Policy, which addresses personal information more broadly.

1. Scope and terminology

A cookie is a small value a server or script can ask a browser to retain and, for many cookies, send with later requests. Local storage is browser storage available to scripts for a particular website origin; unlike an HTTP cookie, its values are not automatically attached to every network request. A browser may also keep cached files, and service providers may process ordinary network requests without placing a cookie. This policy uses “storage technologies” to include cookies, local storage, and comparable mechanisms that store or access information on a visitor's device.

This policy covers the public Site, including its contact and models waitlist pages. It does not govern separate Threeum products, customer accounts, applications, or third-party websites reached through links from the Site. Those services may have their own notices and controls.

2. What the Site stores in your browser

The Site's own code uses the following first-party local storage entries. These are stored for the threeum.com origin in your browser profile; they are not synchronized by Threeum across browsers or devices. Our current contact and waitlist form code does not transmit either value with a submission.

Storage choice: threeum-storage-choice-v2. This records essential when you select “Essentials only” or follow a link to another Site page without choosing, and preferences only when you select “Allow preferences”. Its sole purpose is to remember which option applies so that the choice prompt need not reappear on each page or visit. The Site does not assign this entry a fixed expiration date; it remains until you change your choice, clear the Site's data in your browser, or your browser removes it.
Color mode: theme. If you select “Allow preferences” and choose Light or Dark, this entry stores only light or dark so that the selected appearance can be restored on later visits. It has no fixed expiration date. Choosing Auto removes the entry and follows the browser's system appearance setting. Choosing “Essentials only” removes the entry and prevents the Site from saving a later color-mode selection unless you choose “Allow preferences” again. You can still change the appearance for the current page without saving it.

The choice entry remembers an explicit selection or that optional storage remained off when you continued to another Site page. The color-mode entry is optional and serves only the appearance you request. The Site does not use either entry as an advertising identifier, for cross-site profiling, or to identify you by name. If several people share a browser profile, they may see the same stored choice and color mode.

3. Cookies and processing used to deliver and protect the Site

Cloudflare delivers and protects the Site. Its network necessarily receives technical information associated with requests, such as IP address, requested URL, request time, browser information, and security signals. Depending on which Cloudflare security features are active and whether a visitor encounters a challenge or rate limit, Cloudflare may place security or operational cookies. Their presence can vary by visitor, request, and Cloudflare configuration; listing a cookie below does not mean it is placed on every visit.

__cf_bm may be used when Cloudflare bot protection is active to distinguish automated traffic. Cloudflare states that it expires after 30 minutes of inactivity.
cf_clearance may be used after a Cloudflare challenge or JavaScript detection to remember that the browser passed a security check. Its lifetime is set by Cloudflare's applicable challenge configuration.
_cfuvid, __cfruid, or related security cookies may be used if the corresponding Cloudflare rate-limiting feature is enabled. Their purpose and duration depend on the feature and configuration in use.

These technologies support delivery, abuse prevention, and security. The Site's “Essentials only” choice does not disable Cloudflare's network-level processing or any security cookie required for an active protection feature. Blocking such a cookie in your browser may cause a challenge to repeat or prevent access to a protected request. Cloudflare describes its cookie names, purposes, and current durations in its cookie documentation.

4. Performance information and external resources

Cloudflare can provide aggregate request, performance, and security information from its network independently of the Site's local storage choices. If Cloudflare Web Analytics or real-user monitoring is enabled in the hosting dashboard, Cloudflare may add a browser-side performance beacon when it serves a page. That beacon may report page-load and usage measurements to Cloudflare; it is separate from the two local storage entries described above. The Site's “Allow preferences” button is not consent to analytics, and “Essentials only” does not disable Cloudflare's network measurements. We do not include an advertising pixel, retargeting tag, or cross-site behavioral profiling script in the Site's own code.

Some Site pages request typefaces from Google Fonts. To deliver them, the browser contacts Google-operated domains, including fonts.googleapis.com and fonts.gstatic.com, and shares technical request information with Google under its own practices. Those requests are for display of the page and occur independently of the Site's color-mode storage choice. The browser may cache font files; that cache is distinct from the two local storage entries listed above. See Google's Privacy Policy for information about Google's handling of requests.

Links to X, LinkedIn, or other outside sites do not by themselves place those sites' cookies through the Site. If you follow an external link, that site's own privacy and cookie terms apply.

5. Your choice and how to change it

When no valid storage choice is present, the Site presents two options: “Essentials only” and “Allow preferences”. Both allow access to the Site. If you follow a link to another Site page without choosing, the prompt closes and the Site records essential; this is not treated as consent to optional storage. “Essentials only” also records that choice and leaves optional color-mode storage off. “Allow preferences” permits the Site to save an explicit Light or Dark selection; choosing Auto does not save a color-mode value. Neither option turns on advertising cookies or gives blanket permission for future technologies.

You can change your selection at any time using Cookie choices in the footer of any Site page. Switching to “Essentials only” removes the saved theme entry. You can also use the color-mode control to select Auto, which removes that entry while allowing the Site to follow your browser's reported light or dark setting. If you clear cookies and site data for threeum.com in your browser, the stored choice and mode are removed and the Site will ask again on a later visit. Browser controls, private-browsing modes, or extensions may also block or clear storage.

The footer control manages only the Site's own optional appearance storage and its choice record. It does not delete Cloudflare cookies, stop technical requests needed to deliver the Site, or control Google's separate services. For provider-set cookies, use your browser's site-data controls and consult the provider information above. Some security-protected functions may be unavailable when cookies are blocked.

6. Retention, legal requirements, and changes

The two first-party local storage entries have no programmed expiration date. They remain until you change the relevant setting, clear site data, or your browser removes them. Cloudflare controls the lifespan of any cookies it sets according to the active feature and its configuration. Browser cache retention is controlled by browser and network settings. Technical request logs and form submissions are separate from browser storage; our Privacy Policy addresses the information we receive and retain through the Site.

Applicable privacy and electronic-communications laws may require notice, consent, or a right to object for particular storage technologies. Where required, we will seek the appropriate permission before deploying non-exempt optional technologies under our control. A choice about color mode does not authorize unrelated purposes. If we later introduce advertising, cross-site tracking, or other optional storage purposes, we will update this policy and the relevant choice mechanism before using them. We may revise this policy as the Site or providers change; the effective date above identifies the version in force. Material changes will be communicated or presented for a new choice when applicable law requires it.
