Privacy Policy

Last updated: 26 October 2026

This policy covers the personal software tools published under this domain by Kuk-Hwan (Kevin) Kim (the "tools"), including the applications registered with Google as personal-gmail and volta-gmail. The tools are private: they are used only by the developer and members of his household, on their own computers, with their own accounts.

What the tools do

The Gmail tools read, search and create draft email messages in the signed-in user's own Google account, and read that user's own calendar, in order to help the user prepare correspondence. They run locally on the user's computer.

Data accessed

With the user's consent through Google sign-in, the tools access Gmail message content, draft content, attachments and calendar events of the signed-in account only. Access is limited to the permissions (scopes) shown on Google's consent screen.

How data is used, stored and shared

• Data is used only to display messages to the user and to create or edit drafts the user asked for.
• Data stays on the user's own computer. No message content is transmitted to the developer or to any third party, and nothing is stored on any server operated by the developer.
• The sign-in token issued by Google is stored in a file readable only by the user's own account on that computer.
• Data is never sold, used for advertising, or used to train artificial-intelligence models.

Google API Services User Data Policy

The tools' use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Revoking access

A user can revoke the tools' access at any time at myaccount.google.com/permissions and by deleting the local token file.
