Privacy Policy
Last updated: October 20, 2026
NyankoTools (the "Site") has established this Privacy Policy to explain how it handles user information, including personal information, so that users can use the Site with confidence.
1. Operator Information
The Site is operated by an individual. See theAbout pagefor more details. For inquiries regarding this policy, please contact us using the information in Section 9 ("Contact") below.
2. Our Basic Policy (How Tools Process Data)
Every tool offered on the Site runs entirely as client-side processing within your browser. Data you enter — for text conversion, formatting, calculations, and the like — is never sent to the Site's servers. Your input is processed only within your own browser and is never stored or transmitted externally.
To restore your input after a page reload or a language switch, the Site temporarily keeps it in your browser's session storage (it is cleared when you close the tab and is never sent to any server). Tools that handle sensitive data such as passwords or tokens do not save it.
Tools that use a camera, microphone, screen sharing, or gamepad (such as the webcam tester, mic tester, screen recorder, and QR code reader) process video, audio, and input only on your device, after you grant permission in your browser. Nothing is sent to a server or stored by the Site. You can revoke permission at any time in your browser settings.
The contact page works by opening your email app (mailto), so what you enter never passes through the Site's servers. Your email reaches the operator through your own email service and is used only to reply to you. Share buttons (X, Facebook, etc.) take you to the respective service only when you click them and send nothing automatically.
3. Access Logs
The Site's hosting provider (Cloudflare) may automatically record access logs — such as IP address, browser type, referrer URL, and access timestamps — as part of its standard functionality. This information is used solely for security and maintenance purposes, such as preventing unauthorized access and keeping the Site running stably, and is not used to identify individuals.
4. Analytics and Advertising Services
The Site uses Google Analytics (GA4) and Cloudflare Web Analytics as analytics tools to improve the Site. The Site does not currently use any advertising service, but in the future we may use third-party services such as Google AdSense to support its continued operation. If we do, we will update this policy beforehand.
Google Analytics uses cookies to collect traffic data. Data collected through cookies is anonymous and does not identify you personally. You can opt out of this data collection by disabling cookies in your browser; please refer to your browser's help documentation for instructions. Cloudflare Web Analytics does not use cookies and does not track individuals.
The information sent to outside providers is listed below. Neither includes the text or files you enter into a tool, or file names.
| Recipient / service | Information sent | Purpose |
|---|---|---|
| Google LLC (Google Analytics 4) | Page URL and title, referrer, IP address, device / browser / OS / language, identifiers such as cookies, copy and download actions, and errors (tool name only) | Analyzing site usage and improving the tools |
| Cloudflare, Inc. (Cloudflare Web Analytics) | Pages viewed, referrer, device / browser type, and load performance (no cookies) | Aggregating traffic and improving page speed |
URL parameters that may contain your input (?text=,?q=, ?c=) are removed before being sent to Google Analytics. You can opt out of Google Analytics with theGoogle Analytics opt-out add-on.
For the terms of service and privacy policy of Google Analytics and Cloudflare Web Analytics, please refer to Google's and Cloudflare's official websites, respectively. Third-party vendors, including Google, may also use cookies to serve ads based on a user's visits to the Site and other sites. You can opt out of personalized advertising through Google's Ads Settings page.
5. About Cookies
Cookies are small data files that a website sends to your browser and that are stored on your device. The Site uses cookies through the analytics services described above (only Google Analytics sets cookies). You can refuse cookies or delete cookies already stored through your browser settings.
For convenience, the Site also stores the following in your browser's local storage. None of it is sent to any server, and it is removed when you clear the site's data in your browser.
- Favorite tools, recently used tools (tool names only, up to 8), theme (light/dark), and sidebar open/closed state
- Best scores for game tools and rock-paper-scissors stats
- Issuer details you save in the Invoice Generator, and the UTM Builder history
6. Disclosure of Personal Information to Third Parties
The Site will not disclose any information it collects to third parties without the individual's consent, except in the following cases:
- When disclosure is required by law
- When disclosure is necessary to protect a person's life, body, or property, and obtaining consent is difficult
- When cooperation with a national or local government agency is necessary for it to carry out duties prescribed by law
7. Rights Regarding Personal Information Protection
If you reside in a jurisdiction where data protection laws such as the EU General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA) apply, you have the right to request disclosure, correction, or deletion of information the Site holds about you. To make such a request, please contact us using the information in Section 9 ("Contact") below.
