PrimiLab Personal Information Collection List

Effective date: 2026-08-24 · Last updated: 2026-08-27

This list accompanies the PrimiLab Privacy Policy. It sets out, item by item, the types of personal information the "Micca" app (the "App") actually collects, the scenarios and purposes of collection, how it is collected, and whether each item is required for the corresponding function.

We follow the principle of "minimum necessary": we collect personal information only within the smallest scope needed to provide you with the relevant function. Declining to provide items marked "Optional" will not affect your use of the App's main functions.

Where this list is inconsistent with the Privacy Policy, the wording more favourable to you prevails. Our sharing of personal information with third parties is described separately in the Third-Party Personal Information Sharing List.
