Numbers you type into a calculator

Amounts, rates, ages, and the other fields are processed in your browser so the page can show a result. Sumslip does not put those numbers in the page address, does not run an account system, and does not add them to a publisher database.

Do not put a secret account number into a field. The fields are not built for account numbers.

Records a visit leaves

When you open a page, the company that serves the site can keep the IP address, browser type, requested address, and time in a server log. Those logs are used to run and protect the site. They are deleted after the company's ordinary retention period.

Sumslip does not ask you to create a password, upload an ID document, or submit a resident registration number, social security number, or My Number.

Cookies

Numbers you type are not stored in a cookie. If you choose English, Korean, or Japanese yourself, only that choice stays in this browser for one year. If you do not choose, no language choice is stored.

When ads are on, Google and other third parties may use cookies or similar storage to measure ads, limit how often the same ad appears, and, if you allow it, show ads that relate to you. This site uses Google AdSense. Google's description is at policies.google.com/technologies/ads and policies.google.com/privacy. You can turn off personalized ads at adssettings.google.com, and you can turn off personalized ads for this site with Ad choice in the footer. Non-personalized ads may still appear. Visitors in the EEA, the UK, and Switzerland may also see Google's consent message.

Purposes and retention

A page request is processed to send the page you asked for and to protect the site.

The publisher does not sell a list of calculator users. The publisher also does not use the numbers in the form fields for marketing, because those numbers are not collected on a server.

Your requests

You may ask to see, correct, or delete mail you sent to the publisher. Server logs follow the retention period of the company that serves the site.

If you write to the publisher, the mail contains whatever you put in it. Do not send full card numbers, government ID numbers, or account passwords. Mail is kept long enough to reply and to keep a record of the reply, then deleted when it is no longer needed for that correspondence.

Children

Sumslip is written for adults making ordinary money calculations. It is not directed at children under 14, and it does not knowingly collect personal information from them. If you believe a child sent personal information to the contact address, write to the publisher and ask for that mail to be deleted.
