Privacy Policy & Disclaimer

Personal information & usage data

• This site does not collect any input to its tools (files, text, audio, etc.) or any personally identifiable information from visitors.
• All input to each tool is processed entirely inside your browser and is never sent to this site's server or to any third party.
• To understand overall site usage, this site uses Cloudflare Web Analytics, which does not use cookies or fingerprinting and only collects anonymous, aggregated metrics such as page views. No tool input or personally identifiable information is collected. See Cloudflare's privacy policy for details.
• This site uses Google AdSense as a third-party advertising service. Google AdSense may use cookies to serve ads based on your visits to this and other websites, in order to show ads tailored to your interests. The content you enter into the tools themselves is never sent to the advertising provider.
• You can opt out of personalized advertising and manage cookie preferences from Google's Ads Settings page (https://adssettings.google.com/) . For more details on how cookies are used for advertising, see Google's policy at https://policies.google.com/technologies/ads.
• No other analytics or tracking cookies are used.
• There are no sign-ups or accounts on this site. We accept inquiries by email; if you contact us by email, we use the message and your sender email address solely to respond to your inquiry.

About the issue / request form

Only the content sent via the "Report an issue or request" button at the bottom of the home, category, and tool pages is stored on a server. This is solely for improving the site and does not apply to the input or output of any tool.

• Data sent: the report target (tool slug / category key / home), display language (ja / en), report type (bug / request) and reason category, the free-text detail (optional, up to 2000 chars), and for bug reports only the browser User-Agent header. To rate-limit submissions, the source IP address is hashed with SHA-256 and stored (the original IP cannot be recovered).
• Storage: Cloudflare D1 (a serverless SQLite database operated by Cloudflare). Records are retained for up to 180 days and are then deleted progressively.
• When you press Send, Cloudflare Turnstile runs a bot check. Per Cloudflare's privacy policy, some browser fingerprint information is sent to Cloudflare (see https://www.cloudflare.com/privacypolicy/).
• Please do not include personal information, passwords, or sensitive business data in the detail field. It will be visible to the site operator and within Cloudflare's operational scope.
• We limit the same kind of report to once per day to prevent abusive resubmission.

Disclaimer

• Each tool aims for accurate behavior, but we make no warranty of any kind regarding its content or results.
• For any damages arising from the use of, or inability to use, this site (direct, indirect, or consequential, including data loss and business losses), the operator assumes no responsibility.
• Use of generated or converted output is at your own risk. For important data, always verify the result in your own environment.
• Content on this site may be changed, added to, removed, or taken down at any time without prior notice.
• If links to external sites are included, the operator is not responsible for their content.
