Privacy Policy

This Privacy Policy applies to the collection, use, and disclosure of personal information by Curious Lab Group. We operate as a business name of our legal entity, Gani Software Pty Ltd (ACN 145 036 577).

Your privacy is important to us. We are committed to protecting your personal data. This Privacy Policy outlines how we collect, use, and handle your information when you use our plugin, Hill Chart, for the Linear project management system.

Who we are

We are Curious Lab Group, the creators of Hill Chart, a plugin that helps Linear teams visualize their work progress on a hill chart. The hill chart was invented by Ryan Singer, originally for Basecamp.

You can reach us with privacy questions at [email protected].

Identity & access

When you use Hill Chart, you sign in via OAuth through Linear. We collect your name so we can show who created a hill chart or related objects in the plugin. We also collect your email address to send important operational updates (like authentication issues or service notices), and occasionally to let you know about product improvements.

We do not sell your personal information to third parties. We also do not share your personal information except as required to operate and support the service, comply with the law, or protect our rights.

Integration with Linear

Hill Chart connects to your Linear account only in response to user-initiated actions. For example, we retrieve your Organization name when you sign up or sign in.

We do not use Linear webhooks or other background sync mechanisms. You must manually refresh your hill charts to retrieve the latest issue data from Linear.

We believe in minimal access. We only ask Linear for what we need, and only when you ask us to.

Use of AI

We do not use your data to train AI models. We do not share or repurpose your data for any machine learning or AI development activities.

Billing information

If you choose a paid plan for Hill Chart, your billing information (such as credit card details) is processed by a secure third-party payment processor. We use industry-trusted services to handle all billing and payment transactions. We do not store or have access to your payment information on our servers.

Cookies

Cookies are small text files stored on your device when you visit a website. We use cookies to:

  • Keep you signed in securely to your account.
  • Remember your preferences (e.g. interface settings).

Product analytics

We use a privacy-first analytics tool to understand how Hill Chart is used. This helps us improve the plugin without compromising your privacy.

Data retention

If you unsubscribe from Hill Chart, we retain your data for up to 60 days, after which it is deleted from our systems.

Location of data

All data is stored on servers located in the United States. If your local regulations or internal policies prohibit using services that store data in the U.S., please contact us at [email protected].

Security & anti-abuse measures

To protect our systems and users from abuse—including spam, brute-force attempts, and unauthorized access—we employ an anti-bot system and log certain metadata, including:

  • IP addresses
  • User agent strings
  • Timestamps

This information helps us detect suspicious activity and enforce rate limits or blocks as necessary. We do not use this information to track you personally or for marketing purposes.

Your rights

You can request access to, correction of, or deletion of your data by contacting us at [email protected]. We are committed to honoring these requests promptly and respectfully.
