How your data is handled.

The website

The site may save your language choice in the browser. If you confirm on the homepage that you are 18 or older, the browser remembers it for 30 days. The homepage then loads the official players of the adult sites you choose (Eporner, XVideos, XNXX, Pornhub, YouPorn or RedTube) and video thumbnails from Eporner’s servers. Those sites receive normal request metadata, and their own privacy policies apply. The purchase page keeps the order ID, access code and payment link only in the current tab session. Closing the tab clears them. Save them yourself in a safe place; if an order is linked to an account, recover it through that account. Account and payment features process names, email addresses, password hashes or OAuth identities, sessions, orders and payments, licenses and device grants that users actively provide or request. Plaintext passwords are not stored. KC account session records do not store IP addresses or full User-Agent strings; IP addresses are processed only transiently for security rate limiting. Cloudflare and other providers still receive normal request metadata as part of their services. To stop repeated emails to one inbox, the server keeps a keyed hash of the recipient address, not the address itself, for about a day.

Hosting and web requests

Cloudflare provides the KC portal and public installer delivery. NOWPayments only processes payments when a user chooses an unlimited-use membership, and an email provider handles account messages. They receive normal request metadata needed to provide those services, such as IP address, browser or device information, request time, and payment or email delivery data. See their privacy notices for details. Before the site sends an account email or creates a payment order, Cloudflare Turnstile checks that a person, not an automated program, made the request; it processes browser and device signals for this check.

KC for Mac and your content

KC stores downloaded videos, likes, favorites, watch history and settings on your Mac and does not upload them to the KC website. Deleting a video or the app's data removes it from your Mac. KC contacts the KC website only for your account, the daily download allowance, memberships, support and update checks (reading the public release list and downloading new versions).

KC for iPhone

KC for iPhone keeps your Library, private videos, likes, favorites and watch history on your iPhone. It has no ads, no tracking and no third-party analytics. Some things do reach KC's server:

Site lists and searches: for some sites, KC's server reads the site's list for you, so the site name, page and any search words pass through it. Responses are cached briefly and are not linked to your account.

Some video pages: YouPorn, Thumbzilla and YouJizz video pages are read the same way when you play or download them.

Your account: sign-in, membership and the daily download count.

Sync is off by default. If you turn it on, your likes, favorites and watch history are copied to your KC account (not your videos); turning it off deletes that copy.

Reminders, only if you turn them on in the Home Screen app: the reminder times, your time zone and today's minutes of use.

With the helper in Safari, the pages it reads go only to KC on your iPhone. The websites you open receive normal connection information, as with any browser.

AI support assistant

The support panel on this website includes an AI assistant. Conversations are not saved. The text of your question is sent to Cloudflare Workers AI to produce the answer. KC keeps only a count of questions by category, not your words, IP address or account.

If you are signed in, your trial, membership and latest order status are used to answer you. Do not type passwords, wallet keys, seed phrases or access codes into the assistant.

Accessing video sources

When you open a website or play or download one of its videos in KC, your Mac sends normal network requests to that website, which receives normal request metadata such as IP address, device information and request time. Websites keep their own sign-in, age verification and policies. Playing a saved video does not contact the website again.

Changes and downloads

Account and payment features still process names, email addresses, password hashes or OAuth identities, sessions, orders and payments, licenses and device grants actively provided or requested by users, plus necessary support details and notes. Signing out ends the current account session; closing a purchase tab clears that tab’s order proof. See the download center and your account page for installer and access status.

Membership and orders

A purchase creates an order ID and access code. The server stores the code hash, payment status, license term and device grants. The order ID and code are kept only in the current tab session; closing the tab clears them. Save them yourself in a safe place. If the order is linked to an account, recover it through that account. NOWPayments processes payment and Cloudflare provides the service.
