Information we collect

We collect account details you provide during sign-in, including your email address and basic profile data, along with product usage information needed to provide and improve ChartKit.

How we use information

We use data to deliver core functionality, manage subscriptions, respond to support requests, prevent misuse, and improve product performance and reliability.

Usage analytics

The ChartKit browser extension, desktop app and connector for AI assistants (MCP) collect usage analytics to measure and improve the reliability and usefulness of their features. We record product events, for example when a chart is created, edited, committed to a document, or a keyboard shortcut is used, along with coarse attributes such as chart type and timing. Each event is tied to a random identifier generated on your device and, when you are signed in, to your ChartKit account identifier, so that we can understand how the product performs for a given account. Events never include your name, the contents of your charts, or the contents of your documents. We store these events on our own infrastructure (Supabase, EU). You can turn usage analytics off at any time in the extension's Settings under Privacy, or in the desktop app under Help → Share usage data.

Cookies

The website sets one cookie of its own, cc_cookie, which stores your cookie choice for six months. If you accept marketing cookies, your browser also stores where you came from (campaign or referrer, and the Google ad click id). When you sign up we record this with your account and report the ad click to Google Ads (Google LLC, United States) to measure our ads. If you decline, none of this is stored. We also count page views, install clicks and desktop-app downloads on our own server: the page path or download requested, referring site, country, device type, and a hash of your network address and browser that changes every day and that we cannot reverse to identify you. To change your choice, clear this site's cookies in your browser and the banner will ask again.

Billing and payment data

Subscription payments are processed by third-party billing providers. We do not store full payment card numbers on our servers.

Data sharing

We do not sell personal information. We share data only with service providers that help us operate ChartKit, and only as needed for legitimate business purposes. These providers include our payment processor and, for visitors who accept marketing cookies, Google Ads, which receives the ad click id described above.

Data retention and security

We retain personal data only as long as necessary for service delivery, legal obligations, and legitimate business needs. We apply administrative, technical, and organizational safeguards to protect your data.

Your choices

You may request access, correction, or deletion of your personal information. You may also stop using the service at any time and request account closure. You can turn off usage analytics whenever you like from the extension's Settings under Privacy.

Policy updates

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the effective date above.
