Service Information and Philosophy
Dokdoin Portal (dokdo.in)is a platform of useful free online tools that anyone can easily use anytime, anywhere, as long as they have a web browser. It immediately provides various utility tools needed for daily life and work without membership registration or complex program installation processes.
Data Processing & Privacy Principles
Files (PDF, image, text, etc.) or sensitive calculation data inputted by users into the tools are not transmitted to our servers and are processed securely and independently within the user's browser.
Even without membership registration, recent usage history, favorite tools, and personal settings are safely remembered in the browser cache (LocalStorage) for convenient use on the next visit. However, please note that if you initialize (delete) the browser cache and browsing history, the locally stored setting data will also be deleted.
For some backup features explicitly marked as 'Online Sync/Transfer' (e.g., search engine personal settings backup), only the minimum necessary information is encrypted and securely transmitted to and stored on the server. Even when registering/logging in socially, only the minimum unique key value (nickname) for identity verification is utilized, and real names or email address information is never collected. If you save by logging in, you can retrieve and use the same settings on other devices such as mobile, tablet, and PC.

Since this service independently performs calculations utilizing the local environment of the user's web browser, we do not take legal responsibility for operation losses or data destruction caused by malfunctions due to device specifications, hardware damage of the user's device, abnormal termination of the browser, etc. For more detailed terms and legal regulations, please refer to the Terms of Service menu.
