Start20 - Privacy Policy

Daiki Kawase built the Start20 app as a Free app. This SERVICE is provided by Daiki Kawase at no cost and is intended for use as is.

This page is used to inform visitors regarding my policies with the collection, use, and disclosure of Personal Information if anyone decided to use my Service.

No Data Collection

Start20 does not collect, transmit, or share any personal information or usage data. The app does not require an account, does not connect to the internet, and does not use any analytics, advertising, or third-party SDKs.

All information you enter in the app — habits, session history, and settings — is stored only in a local database on your own device. It is never sent to me or to any third party. If you delete the app, this data is deleted along with it.

The app requests permission to send local notifications (to remind you when a habit starts and when a session ends) and, on supported devices, to display a Live Activity on your Lock Screen while a session is running. Both features run entirely on your device and do not involve any data leaving your device.

Children's Privacy

These Services do not address anyone under the age of 13. I do not knowingly collect personally identifiable information from children under 13 years of age, and since the app collects no information from anyone, this applies equally to users of all ages.

Changes to This Privacy Policy

I may update our Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. I will notify you of any changes by posting the new Privacy Policy on this page.

This policy is effective as of 2026-07-13.
