Privacy Policy

Quick Calc (“this site”) respects your privacy and handles personal information as follows.

Data entered into the tools

Every calculator on this site processes the values you enter entirely within your browser (on your device). The values are never sent to or stored on our servers (except for the poll tool described in the next section).

Data handled by the poll tool

As an exception, the poll tool (in Japanese) stores the questions and options you create, and the votes cast (which option was chosen), in an external database used by this site for tallying. It does not collect information that identifies you personally, such as your name or email address.

To prevent duplicate votes from the same device, a randomly generated identifier is stored in your browser (localStorage) and sent when you vote. This identifier cannot be used to identify you personally.

The creator of a poll can delete it at any time from the device it was created on (via “polls created on this device” on the poll home page, or the delete button on the poll page). Deleting a poll also deletes its votes.

Access analytics

This site may use an access-analytics tool (Google Analytics) to improve the site. The tool uses cookies to collect traffic data; the data is collected anonymously and does not identify you personally.

You can disable cookie-based data collection in your browser settings. For details, see the Google Analytics Terms of Service and the Google Privacy Policy.

Information collected via contact and reports

This site does not accept inquiries by email and does not collect personal information such as your name, email address or phone number.

The contact form (in Japanese) stores the selected category and the message you write in an external database. To prevent repeated submissions, a randomly generated identifier is stored in your browser (localStorage) and sent along with your message. This identifier cannot be used to identify you personally.

When a poll is reported, only the reported poll and a similar identifier are stored. All of this information is used solely to respond to inquiries and to act on inappropriate posts.

Disclaimer

For the disclaimer covering the use of calculation results and information on this site, see the Disclaimer page.

Changes to this policy

This site may revise this policy as needed. Important changes will be announced on this page.
