Privacy policy
Last updated: 11 November 2026
Who we are
PeakDevs is the brand of Peak Devs, registered with the Dutch Chamber of Commerce (KvK) under number 65578155, Shackletonstraat 12, 1056 RM Amsterdam, the Netherlands. Email: privacy@peakdevs.eu.
This policy covers the Confluence Cloud app "PeakDevs Mermaid Diagrams for Confluence" (the app), our website peakdevs.eu, and our support.
The short version
- The app does not collect, store or send any of your data. It draws diagrams in your browser from text that stays in your Confluence pages.
- We receive personal data only when you contact us, and, through Atlassian, the contact details of the customer who installs or buys the app.
- We do not sell personal data and do not use it for advertising.
The app
The app runs on Atlassian Forge, Atlassian's platform for apps, inside your Confluence Cloud site.
- What it reads: the page or blog post a diagram is on, on behalf of the person viewing it, and only when the diagram is drawn from a code block on that page. It reads the diagram text in the macro itself.
- What it does with it: it draws the diagram in the reader's browser. For an export, a function of the app runs on Atlassian's platform, receives the diagram text and gives it back as a code block for the export.
- What it keeps: nothing. The app has no storage. The diagram text stays in your page, where Confluence keeps it under your site's permissions and settings. A macro's display settings are saved by Confluence with the page.
- What it sends: nothing. The app has no permission to contact any address outside Atlassian, and it sends nothing to us or to anyone else. It sets no cookies and uses no analytics or tracking.
So we, PeakDevs, never see your pages, your diagrams or the names of the people who use them.
Atlassian runs the platform the app runs on. Atlassian's own processing is described in Atlassian's privacy policy and your agreement with Atlassian.

Who we share it with
We use these services to run our business. Each processes data only on our behalf:
- Atlassian (Marketplace, billing, and our help desk on Jira Service Management).
- Cloudflare, our website host, to serve peakdevs.eu.
- Our email provider, for our email.
- Our accountant or bookkeeping service, for our accounts.
We share personal data with others only when the law requires it.
Outside the European Economic Area
Some of these services are run by companies outside the EEA, such as Atlassian. Where personal data leaves the EEA, we rely on the EU–US Data Privacy Framework, or the European Commission's Standard Contractual Clauses, offered by those services.
Your rights
You may ask us to see, correct or delete your personal data, to limit or object to its use, or to receive it in a common format. Write to privacy@peakdevs.eu. We answer within one month.
For data in your Confluence pages, ask your Confluence site admin or Atlassian: we hold none of it.
You may complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens (autoriteitpersoonsgegevens.nl), or to the authority where you live.
Security
We protect the data we hold with access control, two-step sign-in on our accounts, and encrypted connections. If a breach affects your personal data, we tell you and the authority as the law requires. See our security statement.
Changes
We change this policy when what we do changes, and update the date above. For a change that matters, we say so on the app's listing.
