Utilo

Privacy Policy

Utilo (the "Site") is a free collection of online tools that you use without an account. This policy explains what information is handled where when you use the Site, and what you can choose or delete.

1. Summary

2. Personal information we collect

The Site does not ask you for, or collect, personal information such as your name, email address, phone number or date of birth. If you enter a name or a birth date into a tool, the value is used only for the calculation in your browser and is not passed to the operator.

Other services do receive the following automatically while the Site is delivered to you. Sections 6 to 8 explain each one.

If you email contact@useutilo.com, we receive your email address and the contents of your message.

3. Why it is used

4. What you enter into tools, and your files

Every tool is JavaScript that runs in your browser. The text and numbers you enter, and the photos, videos and documents you choose, are read and processed only in the browser on your device, and this site does not transmit them. Converted files are downloaded on the same device.

To show ads, Google's ad script also runs on each page. The Site's own code does not send what you enter into a tool, or your files, to anyone, including Google, except that the lunch picker's map links pass the chosen menu name to the map service when you click them (section 9).

5. Browser storage

Some tools keep information in your browser's storage (localStorage) on your device so that you can pick up where you left off. It stays only in that browser on that device, is never sent to the operator, and does not appear on your other devices. The Site's own code does not set cookies. This is what is stored, by purpose:

Tools that work with files (GIF makers, image resizer, PDF converters, documents to PDF and so on) do not keep your files in storage.

How to delete it: clear this site's data ("cookies and site data") in your browser settings, and all of the above is removed. Several tools on the Korean site also have a switch to turn off auto-save or a button to delete what they saved.

6. Advertising and cookies (Google AdSense)

The Site includes the Google AdSense ad code on every page except the 404 error page. Third-party vendors, including Google, use cookies and advertising identifiers to serve ads based on your visits to this site and other sites. Google's use of advertising cookies enables it and its partners to show you personalized ads.

You can read how Google uses this information at How Google uses information from sites or apps that use our services.

If you do not want personalized ads, you can:

The consent process that applies to visitors from the EEA, the United Kingdom and Switzerland follows Google's policies.

7. Hosting access logs (Vercel)

The Site is hosted by Vercel Inc. When you open a page, Vercel keeps standard access logs, such as your IP address, browser details, time of the request and the page address requested. These logs are kept under Vercel's own policy, and the operator does not try to identify you from them.

8. Font loading (jsDelivr)

The screen font (Pretendard) is loaded from jsDelivr, a public CDN. While the font files are downloaded, your IP address and browser details are passed to jsDelivr and its delivery network.

9. Links to other sites

Some tools link to other sites. These links open in a new window only when you click them.

Other sites handle information under their own policies. The Site's Korean front page carries a Naver site-ownership tag (a meta tag), which sends no information to Naver.

10. How long information is kept

The only personal information the operator keeps is email sent to the contact address. Emails are kept only as long as they are needed to reply and to check a report, and are deleted one year after the request was handled. If you ask, they are deleted sooner. Information in browser storage stays on your device until you delete it. Information received by the advertising, hosting and font services is kept under each company's policy.

11. Sharing, service providers and transfers abroad

The operator does not sell or give your personal information to anyone. To deliver the Site, however, the following service providers outside Korea receive connection details directly from your browser. All three receive them automatically, over the internet, when you open a page.

Email sent to the contact address passes through a mail-forwarding service before it reaches the operator's mailbox, so the sender's address and the message are processed by the forwarding and mailbox services. The operator keeps the sender's address and the message, uses them only to reply, and deletes them on request.

Send any question about these services, or a request to stop processing, to contact@useutilo.com.

12. Deletion

Emails are deleted from the mailbox one year after the request was handled, or sooner if you ask. Nothing you enter into a tool, and none of your files, is stored on the Site's server, so there is nothing else to delete. You can delete browser storage yourself as described in section 5.

13. Your rights and how to use them

14. Security

The Site is served over encrypted HTTPS. It is built so that what you enter and your files are not collected on the operator's server, which keeps the amount of stored information to a minimum.

15. Children

The Site is not directed at children under 14 and does not knowingly collect personal information from children. If we learn that an email came from a child under 14 without a parent's or guardian's consent, we delete it. A child under 14 who wants to email us should do so together with a parent or guardian.

16. Person responsible for privacy

Privacy contact: the Utilo operator (contact@useutilo.com)

The Site does not collect personal information such as names or contact details from visitors. The only exception is email that you choose to send to the address above. It reaches us through a mail-forwarding service (section 11), is used only to reply to you, and is deleted on request. Please send any privacy question or complaint to that address.

17. Where to get help
