Subscription expiring soon - Selfhosted

[swissbuechi]

I recently discovered your awesome expense tracking tool, used the public app with a local account for a few weeks and decided so set up my own server + app.

Installation via ansible + terrafrom with docker + cloudflare tunnel went fine.
Had to remove all email server related env vars, else the server would fail with an error 500 saying: socket.gaierror: [Errno -2] Name does not resolve since the example SMTP host could not be resolved.

Once I migrated my local account to the server, I started to receive this banner:

When I click on subscribe, it takes me to the settings and keeps loading forever:

I did not configure any SaaS or Stripe related env vars.

Do I still need a subscription when I self-host everything? Regarding the docs, I figured it would be completely free:

We made it simple for you to install and run your own instance at no cost. You will have access to all features without any limitation. Have a look at our documentation about how to do so.

Thank you for clarification.
