Privacy policy updates 30 May 2024


Data security and privacy are central to our diagramming tool - using our application platform, your diagram data storage means saving and loading is direct between your browser and whichever location your choose to save your diagram file. We don’t allow your diagram data to be stored on our servers.

We take the same privacy and security focused approach to non-diagram data too here at JGraph - we don’t use cookies or tracking pixels on our website.

Of course, if you contact us here at JGraph for support via GitHub, Google Groups, or one of our social channels, we will have your contact details - necessary to resolve your query.

In our updated privacy policy, we have now clarified that we will not send you any marketing communication using your details or data. We will also not share your personal data with any third-party company for marketing purposes.

Note: The app listings in the Atlassian Marketplace for Confluence and Jira are managed by Seibert Media GmbH, and therefore are governed by their privacy policy.

Note: There are few functions that use the servers to perform operations that browsers are not capable of, including to generate a PDF version of your diagram, and import a diagram file in certain formats (.gliffy, .vsd, .vdx or .vssx). These functions won’t be available if you lockdown data transmission.
