Privacy Policy

Henkan.site is operated by Mirai Soft, (“Henkan.site,” “we,” “us,” or “our”). The operator is responsible for personal information described in this policy, subject to applicable law.

Files and conversion content

The file tools read and process the files you choose in your browser. Henkan.site does not receive those files or their contents on a file-processing server. We do not create accounts, maintain conversion histories, or use file contents for advertising or model training.

Website connection data

When your browser requests the site, the hosting and delivery infrastructure may process technical connection data needed to deliver and protect the site. This can include an IP address, request time, requested page or asset, browser and device information, and referrer information. The exact information, retention period, and infrastructure providers depend on the hosting configuration.

Preferences and messages

If you change the color theme, your browser stores that preference in local storage under the key convert-theme. This preference stays on your device and is not sent to Henkan.site. If you email us, we process the address and message you send so we can respond and keep appropriate correspondence records.

Henkan.site does not currently use accounts, payment forms, advertising pixels, or third-party analytics in the site application.

We use the limited information described above to:

• Deliver the pages, tools, and downloads you request.
• Remember the display theme you selected on your device.
• Maintain the availability and security of the website.
• Respond to privacy requests and other messages you send us.
• Meet legal obligations and protect legal rights where needed.

Where privacy laws require a legal basis, processing may be based on providing the service you request, our legitimate interests in operating and securing the site, your consent where required, or compliance with a legal obligation.

Conversion takes place in your browser using the device’s available processing and memory. Source files are not sent to our file-processing servers or stored in a Henkan.site account.

The browser may temporarily hold selected files and generated results in memory while a tool runs. If you download an output, your browser saves it according to your own download settings. Closing the page or clearing browser data removes temporary browser state, except for files you chose to download.

We do not sell personal information or share it for cross-context behavioral advertising. We do not disclose the files you select to third parties through the conversion tools.

The website’s hosting or delivery providers may process connection data on our behalf to serve and secure the site. They are not given your local conversion files by the tools. We may also disclose information if required by law or when reasonably necessary to protect people, the service, or legal rights.

The site application does not use advertising or analytics cookies. It stores your selected light or dark theme in your browser’s local storage. You can remove that preference by clearing the site’s local storage in your browser settings.

Hosting or security infrastructure may use strictly necessary technologies to deliver or protect the website. Any such infrastructure-level technologies are controlled by the relevant provider and should be described in its own disclosures.

Henkan.site does not retain conversion files on a file-processing server because the tools process them in your browser. The theme choice remains in local storage until you change it or clear site data.

Hosting providers may retain connection logs for periods set by the hosting configuration, security needs, and applicable law. Messages sent to us are kept as long as reasonably needed to respond, maintain appropriate records, and meet legal obligations.

The site’s hosting and delivery infrastructure may process connection data in countries other than the one where you live. Any international transfer is subject to applicable legal requirements and safeguards. The hosting provider and relevant transfer details should be confirmed in the operator and hosting disclosures.

We do not sell personal information or use it for targeted advertising. To submit a privacy request, contact us using the details in Section 12. We may need to verify your request before acting on it. We will respond as required by applicable law.

The theme preference stored only in your browser can be removed directly through your browser’s local storage settings; we do not have access to delete it remotely.

Processing files in your browser means the conversion tools do not transmit their contents to our processing servers. We and our infrastructure providers use reasonable measures to protect the website and any technical information handled to serve it. No website or internet transmission can be guaranteed completely secure.

We may update this policy when the tools, infrastructure, or applicable requirements change. The date at the top shows when this version was last updated. If a change materially affects how information is handled, we will provide additional notice where required by law.
