GrowVolution e.V.

The association's public website — deliberately small, and deliberately temporary.

This repository holds the website of GrowVolution e.V., a German non-profit association registered at the Amtsgericht Braunschweig under VR 202639. It runs on WebFluid, a fullstack Python runtime on top of FastAPI.

Live at https://growvolution.org.

Why it exists

This is not the association's product. It is the smallest site that discharges three obligations and one convenience:

1. A single, citable Imprint. Everything the association publishes — repositories, Matrix rooms, mailing addresses, printed material — links to one /imprint, so the § 5 DDG details live in exactly one place and change in exactly one place.
2. A single, citable Privacy Policy. Same reasoning. /privacy covers the whole network the association operates, not just this page, and is the address every other service points at.
3. A rough overview of what we actually do, for anyone who arrives from a link and wants to know who is behind it before reading the legal pages.
4. The association-operating functions that are useful to have online — today that means donations, receipts included.

Everything beyond that is intentionally absent. When the association's actual platform is ready, this site is expected to be replaced rather than grown.

What is on it

Path	What it is
/	The overview page
/imprint	Impressum (§ 5 DDG)
/privacy	Datenschutzerklärung, covering the whole network
/donations/	Donation page — one-off or monthly, via Stripe
/donations/validation	Public check of a donation receipt's seal and integrity
/donations/admin/	Administration of the receipt seal and the donation ledger
/robots.txt, /sitemap	Generated from SITE_PAGES in fluid/config.py
/.well-known/matrix/server	Server delegation for the association's Matrix homeserver

The donation flow is worth a sentence, because it is the only part with real moving pieces: a donor gives once or monthly without ever creating an account, and whenever they leave a billing address with us, a Zuwendungsbestätigung on the officially prescribed form is generated, sealed with the association's own signing certificate, filed, and mailed out. The address is collected on our own page, not by the payment provider. See additives/donations-de/README.md for the whole picture and additives/donations-de/PROCESS.md for the Verfahrensdokumentation the tax office gets.

app_configs/ and additives/ are gitignored — git status will not show edits in there. app_configs/main.example.ini shows the shape of the config a deployment needs.

Running it

Requires Python 3.14+ and a checkout of the additives listed above.

wf run main -d

-d is debug mode: template auto-reload, the detailed error page, the [dev] config section. Never use it for a deployment — that is plain wf run main. Logs land in logs/main/<timestamp>.log, one file per run.

After a model change:

wf migrate revision main -a -m "what changed"

Read the generated revision before applying it with wf migrate upgrade main.

---

Configuration

Everything that is not a secret lives in fluid/config.py: the association's name, address, board, register entry, contact details, the Matrix community, the theme, the sitemap and the mail colour palette. main.py exposes those as Jinja globals (association, ADDRESS, BOARD, MAIL_THEME, …), so the imprint, the privacy page and every outgoing email read them from one source.

Secrets and per-deployment switches — the database URI, the Redis URI, the mail credentials, the Stripe keys, the signing passphrase — belong in app_configs/main.ini, which is never committed.

The copyright holder has granted GrowVolution e.V. a free-of-charge licence to use these modules for the purpose of operating the association's website.
