1. Introduction

This Privacy Policy describes how Sia Makerlab ("we," "us," or "our") collects, uses, and shares information in connection with your use of the Caldo mobile application (the "App").

Caldo is a calendar and to-do app that stores your data locally on your device. It does not require you to create an account, and we do not operate a server that stores your schedule. By downloading, installing, or using the App, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree, please do not use the App.

2. Information We Collect

2.1 Information You Provide

The App is designed to function without an account or personal information. We do not collect your name, email address, phone number, or physical address.

The content you create — your Actions (events and tasks), titles, notes, dates, times, and recurrence rules — is stored locally on your device and is not collected by us.

The App stores the following data only on your device:
