Privacy policy
Applies to Mermaid Diagrams & Flowcharts for Confluence and to this website. Last updated 26 July 2026.
In short: the app does not collect, transmit or store your data anywhere outside Atlassian. Diagrams are rendered in your own browser. There is no account, no server of ours, and no third party involved.
What the app stores
The configuration of each diagram macro you create: the diagram source you type, your display preferences, the diagram engine version, and a cached copy of the last rendered image.
All of it is stored in the Confluence page itself, inside your own Atlassian site — versioned, exported and deleted along with the page, exactly like any other content you write. We have no database and store nothing anywhere else.
What the app transmits
Nothing. The app declares no external permissions, so the Atlassian platform prevents it from making outbound network requests. There is no analytics, telemetry or error reporting, and no fonts, images or code loaded from anywhere else.
What the app can access
The app requests no Atlassian API permissions (scopes). It cannot read your pages, spaces, attachments, comments or user directory. It sees only the diagram macro being displayed, plus the colour theme and whether the viewer is signed in.
Personal data
The app does not collect personal data — no names, email addresses, account identifiers, IP addresses or usage records. Anything you type into a diagram is stored in your own Confluence page, under your organisation's control, and never leaves Atlassian.
Retention and deletion
Deleting a diagram, a page or the whole site removes the data with it. Uninstalling the app leaves nothing of ours to delete.
Sub-processors
None. The app has no infrastructure of its own and shares data with no one.
This website
No cookies, no JavaScript, no external resources, no analytics. Our web server keeps standard access logs for security and diagnostics.
