Who we are

Kline Technology LLC, doing business as Showcard ("Showcard", "we"), Tulsa, Oklahoma, United States, operates useshowcard.com and the Showcard application. Contact: hello@useshowcard.com.

This website

We use Cloudflare Web Analytics on this site and in the Showcard app to understand page views and performance. It does not use cookies or local storage and does not build a profile of you; it records things like the page visited, referrer, browser and country. We do not use advertising pixels or tracking cookies. If you arrive with utm_ or ref parameters in the link, a small script copies them onto the links to our app or demo on that same page. They are not stored in your browser.

If first-party analytics is switched on, the site sends a small event (the page path, the name of a button you used, and any campaign parameters) to our own endpoint. It sets no cookies and sends no names, email addresses or message text.

Our server infrastructure (Cloudflare) processes ordinary request data, such as your IP address, to deliver pages and protect against abuse.

Talking to a person and the contact form

If you use the chat widget or the contact form, the messages you type, and any name, email or agency you choose to give, plus the page you were on and any campaign parameters, are sent to us so we can reply. They may be delivered to our team's messaging tools, and are stored so a conversation can continue. If delivery to our team is unavailable, the page tells you your message was saved rather than delivered.

We use this information only to answer you and to understand what visitors ask. We add you to a marketing list only if you tick the separate, unchecked consent box.

Cookies and similar technologies

Browsing this website does not store anything on your device: no cookies, no local storage, no session storage. For that reason we do not show a cookie banner. Under the EU ePrivacy rules the same applies to local and session storage as to cookies, so this list covers all of them.

Only when you act do we store something, and only what the thing you asked for needs. The chat widget saves a conversation key (named sc_chat) in your browser's local storage after you send your first message, so you can return to the conversation; it is removed when you end the chat. The contact form loads Cloudflare Turnstile, a spam check, when you start filling it in; Turnstile is operated by Cloudflare and may use storage strictly necessary for that security check.

In the Showcard application and demo we use strictly necessary cookies: a sign-in session cookie (agency accounts), a demo-session cookie (demo workspaces), and a cookie that remembers that you entered a PIN for a private client package link. The application also keeps a flag in session storage to reload the page once after we publish an update. None of these is used for advertising or tracking.

We do not use advertising pixels or tracking cookies. If we ever add one, we will ask for your consent first and update this page in the same change.

Email you send us

If you email us, we keep the message and your address to reply and to keep a record of the conversation.

The Showcard application

Agencies that use the application store business records, such as talent profiles, clients, projects and messages. The agency is responsible for that data and for having the right to use it, and we process it on the agency's behalf to provide the service. Details of retention, export and deletion will be set out here and in the Terms before general availability.

The demo contains fictional data only. Please don't enter real personal information into the demo; demo workspaces are temporary and are not migrated to real accounts.

Sub-processors

These companies process personal information on our behalf to run Showcard. We will update this list when it changes.

Cloudflare (hosting, network, spam protection, web analytics, file storage, email routing). Neon (database hosting). Plunk (sending email). Anthropic (AI model provider for the assistant; content is sent to it only to answer your request). Stripe (subscription payments). Slack (delivering chat and contact-form messages to our team).

Your choices

You can ask us to access, correct or delete personal information we hold about you by emailing us. Which laws apply to you (for example GDPR or CCPA) is under review, and we will describe the rights we honor once that review is complete.

Children

Showcard is for businesses and is not directed to anyone under 18.

Changes

We will update this page, and its date, when this policy changes.
