| Where | Off with |

- | The app, Earnings | the Dev fee switch under the money rows |
+ | The app | no switch: the fee is fixed at 1% and Settings shows it, last on the page |
| The command line | --dev-fee 0 |
| HiveOS, extra config | DEV_FEE=0 |
| Mining to a pool | nothing to turn off: the pool issues the templates, so the 1-in-100 mechanism does not exist, and the pool's own fee is the only one |
