Privacy Policy

Last updated: August 24, 2026

This policy describes what the Theme Kit documentation website ( theme-kit-dev.vercel.app) stores and why. It covers the site — not the Theme Kit library itself, which runs entirely inside your own application and stores whatever your app tells it to store.

What this site is

The site is an interactive documentation website: documentation pages, a playground, and client-side search. It has no accounts, no login, no comment system, and no forms that submit data to a server.

Cookies

The site sets four first-party cookies to remember your theme preference so the server can render the correct theme on your next visit. They are set only when you change your theme preference, and they are not used for advertising, analytics, or cross-site tracking.

theme-name — the resolved theme name you selected.
theme-family — the theme family you selected (for example mint).
theme-mode — light, dark, or system.
theme-fingerprint — a short identifier of the site's current theme set, used to ignore stale cookies after the site updates its themes.

All four are set with SameSite=Lax, path=/, and a one-year lifetime. You can remove them at any time by clearing cookies and site data for this site in your browser.

Browser storage

localStorage — one key, theme-selection, holding your theme preference (mode and family). It is written when you change the theme and read on load. It stays only in your browser and is cleared with your browser's site data.
sessionStorage — a few keys (such as the docs sidebar scroll position) that preserve UI state while you navigate the site. They are cleared when you close the tab.
In-memory timezone — the site's sunrise/sunset scheduling reads your browser's local timezone to compute when to switch themes. This is used only in your browser and is never transmitted.

Search

Site search runs entirely in your browser over a search index that ships with the site. Search queries never leave your browser and are not logged.

Playground

The playground (theme switching, presets, token editing) runs entirely in your browser. Nothing you do there is transmitted to us.

Third parties

Hosting — the site is served by Vercel. Like any hosting provider, Vercel records standard server logs (request time, IP address, user agent) in line with its own privacy policy. We do not add analytics scripts to the site.
Fonts — the site's fonts are downloaded at build time and self-hosted. No font files are requested from Google or any other domain when you visit.
Outbound links — the site links to GitHub, npm, and X/Twitter. Once you leave the site, those services' own policies apply.

What we do not collect

We do not collect your name, email address, or account information. We do not run analytics, advertising, or third-party trackers. We do not store your themes, configurations, or any files you create in the playground on our servers. Theme Kit is a library — your applications remain yours.

Changes

If the site changes in a way that affects this policy (for example, adding analytics or a contact form), this page will be updated with a new effective date.

Contact

Questions about this policy can be directed to the project maintainers at thememkproductions@gmail.com or through the GitHub repository.

This policy describes the site's actual behavior as of the date above. Please have final legal text reviewed by a qualified professional for your jurisdiction.
