The data collected includes:

    An email contact associated with each subdomain
    Simple web logs on main domain (trilium.cc - not your subdomain)
    Docker statistics. Basically just usage statistics of memory, network, storage, etc. Example:

CONTAINER ID   NAME        CPU %     MEM USAGE / LIMIT

    Stripe, my payment processor, also has a privacy policy which applies: https://stripe.com/privacy

The data that I will not collect:

    Any metadata or analytics data about page views, site usage, IP addresses, request logs (excepting what is collected by the Trilium app), etc, on your subdomain.
        I do not use Cloudflare or any other CDN, meaning there is no middlemen besides regular internet infrastructure. Just my server and your device, having a heart-to-heart (no eavesdroppers!)
    Any of your personal information with the purpose to profit or benefit by the selling or leasing or distribution of your personal data to any third party. This is a privacy-friendly service. I will rm -rf / before I sell your data to anyone else. 


  Type of data                                     Data I collect                                                                                                                                                                                                                                                                                                        
 ------------------------------------------------ ------------------------------------------------ 
  Personal information (emails, usernames, etc)    Your email and payment events via Stripe will be stored (contains no sensitive payment info like card number). Other events are not stored.                                                                                                                                                                           


  Public data (intended to be shared)              The subdomain's existence (example.trilium.cc) will be public, as TLS certificates are public. Any shared notes will be available publicly on the domain visible in the Trilium UI. The Rustpad service I also host keeps all documents for 24 hours until the last activity, after which they will be removed.   
  

  General data (payment, third party)              This is handled by Stripe and their privacy policy applies: https://stripe.com/privacy                                                                                                                                                                                                                                


  Confidential data (passwords, credit cards)      The Trilium Notes password is stored within the database, scrypt-encoded. (This is handled by Trilium Notes) I do not handle any credit cards or payment in general directly. Stripe's privacy policy applies.
