This page gives a plain-language summary of the information Trainerrr uses, what it does not access, and what controls are available inside the app.
| Type of information | Examples in the app | Required? | How it is used |

| Workout, nutrition, and goal data | Workout plans, workout logs, goals, exercise selections, reps, weights, calories burned, food names, servings, calories, macros, fiber, and sugar | Used only when these features are used | Used to power necessary planning, workout logging, nutrition logging, and progress history |
| MCP and ChatGPT app requests | Workout, nutrition, target, journal, progress-check-in, and image-reference details users choose to send through the connected MCP client | Optional | Used only to complete the requested Trainerrr action for the signed-in account |
| User-created exercise content | Custom exercise entries created by the user | Optional | Used to support personal exercise libraries and search |

Food search uses Open Food Facts nutrition data. Selected foods are saved to the user’s account so they can be reused in future logs. MCP clients only receive the tool results needed for the request the user made.
Trainerrr includes an account deletion flow. In the current version, deleting an account removes the authenticated user and deletes user-linked workout data, nutrition data, goals, and custom exercises. The app also attempts to remove the stored avatar file during deletion.
Users can also update profile details, change passwords, decide whether to accept analytics sharing during authentication, and manage workout and nutrition content inside the app.
