Privacy Policy

Learn how Fineuralab and Toolkits handle local processing, analytics, advertising, and user data.

Last updated: September 9, 2026.

Local processing

Fineuralab builds practical browser products such as Toolkits. Most tools run in your browser after the page loads. Text, JSON, images, tokens, generated values, and other tool inputs are not intentionally uploaded by these tools unless a specific future tool clearly says that network processing is required.

Information stored in your browser

Toolkits may store small preferences in your browser, such as language choice, recently used tools, favorites, and local tool state. You can clear this data from the Toolkits sidebar or through your browser settings.

Some tools may create shareable setup links that encode tool options, such as a selected mode or chunk size, in the URL fragment. These setup links are intended to store configuration only. They should not include pasted tool input, generated output, credentials, logs, private documents, or other sensitive content.

Course answers and private notes

The logic and statistics courses store answers, hint use, review records, and private notes in this browser's localStorage. The course module does not upload this content or send lesson-completion events. Records do not sync across devices or browser profiles. Clearing site data or ending a private-browsing session can remove them.

Exporting a course record downloads a JSON file containing that course's answers and notes. Keep it private. Importing a compatible file reads it locally and asks for confirmation before replacing this course's record. Reset removes this course's local record, not other course or tool data.

The course copy-link button copies only the public page address. It removes query parameters and fragments, and does not include answers, progress, or notes. Opening a shared page is still a normal website visit subject to the advertising and analytics practices below.

Email and support

If you email Fineuralab, the message, your email address, and any details you include may be used to respond to your request, fix bugs, or improve the site. Please do not send passwords, production tokens, customer data, private documents, or confidential information by email.

Third-party requests from browser tools

Some tools may intentionally contact a third-party public service when that connection is necessary for the feature and explained near the tool. For example, GitHub Skill Analyzer asks your browser to request public GitHub API and raw file URLs for the repository you enter. These requests go directly from your browser to GitHub. Fineuralab does not proxy those requests, store repository analysis content, or receive your GitHub credentials. GitHub may receive information normally included in web requests, such as IP address, browser details, requested repository URLs, and timing, and GitHub's own privacy policy and terms apply.

External links

Fineuralab links to external websites such as GitHub repositories and Google policy pages. External sites have their own privacy practices, cookies, analytics, and terms. Opening those links is outside Fineuralab's local browser tool environment.

Advertising and Google AdSense

Tool pages, learning pages, category lists, the review pilot workbench, and pages marked as not indexed do not load our Google advertising or analytics scripts. Other pages include AdSense code; ad display also depends on Google approval and advertising settings.

Fineuralab may use Google AdSense or other advertising services to support the site. When ads are enabled, Google and other third-party vendors may use cookies, local storage, web beacons, IP addresses, device identifiers, and similar technologies to serve ads, limit repeated ads, personalize or non-personalize ads, measure performance, and prevent fraud or abuse.

Google explains how it uses information from sites and apps that use its services at Google's business data responsibility page and in related Google privacy resources.

Your choices

We use Google’s published consent message for visitors in the EEA, UK and Switzerland. It offers consent, refusal and individual options. Google CMP communicates your decision to Consent Mode for advertising and analytics storage. Where the message is available, use the button below to reopen it.

You can control cookies through your browser settings. You can also manage Google ad personalization through Google's advertising controls where available. If you are in the European Economic Area, the United Kingdom, or Switzerland, Google requires legally valid consent for certain cookie and personalized advertising uses where applicable.

Analytics

Fineuralab uses Google Analytics 4 to understand aggregate traffic, page views, engagement, referrers, approximate location, browser and device information, and events such as scrolling or outbound clicks. This helps maintain the site, improve tools, and understand which pages are useful.

Fineuralab does not intentionally send tool inputs such as pasted text, JSON, tokens, images, or generated values to Google Analytics. Google Analytics may use cookies or similar technologies. For visitors in the European Economic Area, the United Kingdom, and Switzerland, Google Consent Mode is configured to deny advertising and analytics storage by default until consent is provided where applicable.

With Consent Mode, denied storage does not mean that every network request stops: Google may receive cookieless signals. Google explains its processing in How Google uses information from sites or apps that use our services.

Hosting and delivery

Firebase Hosting and Cloudflare deliver the website. Their infrastructure processes request information such as IP addresses, requested URLs and browser headers. Cloudflare also injects a performance measurement script on the public domain; this is separate from Google Analytics.

Children

Fineuralab is not directed to children under 13, and the site is not designed to knowingly collect personal information from children.

Policy updates

This policy may be updated when products, advertising, analytics, or legal requirements change. The last updated date will be changed when meaningful updates are made.

中文说明

当前工具主要在浏览器本地处理数据。网站已接入 Google Analytics 4 和 Google AdSense 相关代码；未来如果某个工具需要联网、账号或 AI API，会在页面或本政策中尽量明确说明。
