1. Information We Collect

- Content: Your diagrams (macros) are stored within Confluence, not our systems.
- Analytics: We use Mixpanel to track anonymous usage events (e.g., creating, editing, or saving a macro). No personally identifiable information (PII) is collected.
B. IntelliJ IDEA & VS Code Plugins
- Authentication: No login is required.
- Personal Data: We do not collect email addresses or user account details.

- Personal Data: When you sign up, we collect your email address to create and manage your account.
- Usage Data: We may collect data such as IP address, browser type, pages visited, and time spent, to improve the service.
- Cookies: We use cookies and similar technologies to remember preferences and support analytics.
2. How We Use Your Data
We use collected data to:
- Provide, maintain, and improve our services
- Notify you about changes or updates
- Support customer service requests
- Analyze usage to improve features and performance
- Ensure security and prevent abuse
We are transitioning towards server-side tracking to further minimize data collection.
3. Data Residency & Retention
- Confluence Plug-in: Your diagrams remain stored in Atlassian Confluence. For analytics, we may process macro data on our servers, which is periodically purged. You can opt out by submitting a request at: https://zenuml.atlassian.net/servicedesk/customer/portals
- Web App: Your account and diagram data are stored on our servers. We retain data only as long as necessary for providing the service, unless required otherwise by law.
4. Disclosure of Data
We may disclose information only if required to:
- Comply with legal obligations
- Protect and defend our rights or property
- Prevent or investigate potential misuse
- Ensure the safety of our users and the public
5. Security
We take strong measures to protect your data. Any data transmitted to our servers is encrypted both in transit (using SSL/TLS) and at rest.
6. Third-Party Services
- Mixpanel: Used for analytics on usage events (no PII).
- Google Analytics: May be used for anonymous web traffic analysis on our website.
You can opt out of Google Analytics tracking by installing the Google Analytics opt-out browser add-on.
7. Children's Privacy
Our services are not directed to children under 13. We do not knowingly collect personal data from children. If you believe we have done so, please contact us and we will delete it.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Updates will be posted on this page, and we will notify users of material changes.
