Overview of Processing Operations

Categories of Processed Data

Miximizer-specific rule:

Users may upload proprietary production data to execute optimization models.

Miximizer is designed so that uploaded production, optimization input, and optimization output data are processed transiently for calculation purposes and are not persistently stored as part of normal platform operation.

Optimization datasets and optimization results are discarded after processing unless explicit user action or consent requires retention (e.g., user-requested persistence, exports, audit features, or support requests).

Miximizer may retain limited operational and analytical metadata that does not contain proprietary optimization datasets or optimization results, including:

Such metadata is used exclusively for:

Operational analytics are designed to avoid inclusion of proprietary production formulas, recipes, optimization coefficients, or optimization results.
