TITLE="No Formal Terms · Dual Currency Notice"

BODY_MD='# No Formal Terms · Dual Currency Notice

This is a **self-hosted GNU Taler merchant backend** at `taler.hacktivism.ch` (hacktivism.ch).

**No formal terms of service** from Taler Operations AG (or any other third-party portal operator) apply to this instance. This short notice is the site policy for using the backend.

## Dual currency

This backend is configured for **two currencies at once**:

- **GOA** — explorational / experimental currency of the local stack (`exchange.hacktivism.ch`, `bank.hacktivism.ch`). GOA is **not** legal tender. It has **no guaranteed real-world value**, redemption, or convertibility.
- **CHF** — Swiss francs, a **real** currency. CHF amounts are real money settled via the CHF exchange configured on this host (taler-ops / TOPS infrastructure as deployed). Treat CHF with the seriousness of ordinary payments.

By creating a merchant instance, accepting payments, or otherwise using this service you acknowledge that:

- GOA is for exploration and testing only.
- CHF involves real money — only use funds you control and can afford to risk on a self-hosted experimental stack.
- There is no guaranteed availability, support, or uptime.
- Operators may reset GOA state, change configuration, delete instance data, or interrupt service without notice.
- Software is provided as-is, without warranty.

If you do not agree, do not use this merchant backend.
