Genki ("the app", formerly Planner Z) is a free, non-commercial personal project run by Niklas Steinfurth for a small group of invited users. By using it, you agree to these terms.
The app creates, moves and deletes workout events in your Google Calendar based on your requests and the plans you approve. It only edits or deletes events it created itself. Please check the plans it creates. You are responsible for the changes you ask it to make.
Training plans are calculated by the app's training engine and explained by an AI model, and may contain mistakes. They are not medical, health or professional coaching advice. Listen to your body, and consult a doctor or qualified coach before starting or changing a training programme.
The app is provided "as is", without any warranty. It may be unavailable, change, or be shut down at any time. To the extent permitted by law, the operator is not liable for any damages arising from its use, including missed, duplicated or deleted calendar events.
How your data is handled is described in the Privacy Policy.
These terms may be updated from time to time. Continued use of the app means you accept the current version.
