What data we collect
Account data
If you choose to sign in, we store your email address in our database. It is used solely to identify your account and send one-time login codes. We do not store passwords.
User content
Production complexes you create, their names, tags, and graph data are stored in our database so you can retrieve them later. Public complexes are visible to other users; private complexes are visible only to you.
IP address
Your IP address is temporarily used for rate-limiting (preventing abuse). It is not stored in our database and is not linked to your account.
Session cookie
We use a single, strictly necessary HTTP session cookie to keep you logged in. This cookie contains only an opaque session ID — no personal data. It expires when you close your browser or log out.
What we do NOT collect
- We do not use analytics, tracking pixels, or advertising cookies.
- We do not share your data with third parties.
- We do not sell your data.

All data is stored on servers located in the European Union. By using this service you acknowledge that your data is processed on EU infrastructure.
Your rights
You have the right to:
- Access — view all your complexes from the Browse tab.
- Deletion — request deletion of your account and all associated data by emailing support@coi-planner.com. Requests are processed within 7 days.
- Portability — your complex graphs are accessible via the API at
