Privacy Policy

This policy explains how this site (www.aiyadianzi.cn) handles visitor data. Our principle is minimal collection — and our architecture is deliberately built so there is little to collect.

What we do NOT collect

• All online tools (word counter, JSON formatter, timestamp converter, password generator, color converter, image compressor, encoder, focus timer) run locally in your browser: text you type, passwords you generate, and images you compress are never sent to our servers, never stored, never reprocessed;
• We require no registration and collect no names, phone numbers, addresses, or identity documents;
• There are no comments and no newsletter, hence no subscription data.

What we do collect

• Server logs: like nearly all websites, our server automatically records anonymous access logs (IP address, time, page, browser type/language) solely for security (blocking malicious scans) and troubleshooting. Logs are rotated and purged on schedule;
• Advertising cookies: this site serves ads via Google AdSense to stay free. Google and its partners may use cookies (including third-party cookies) to personalize ads on this and other sites. You can opt out of personalization at Google Ads Settings (adssettings.google.com) or clear/block cookies in your browser.

Data security

The site enforces HTTPS everywhere; the server exposes only necessary ports behind a firewall; we use no third-party analytics or user-profiling services.

Children

This site is for a general audience and does not knowingly collect data from children. If you believe a child has provided us personal information, contact us and we will delete it promptly.

Your rights

Since we hold almost no personal data, there is usually nothing to query, correct, or delete. If you believe our logs contain sensitive information about you and request deletion, email us with details and we will handle it after verification.

Changes

Material changes will be posted on this page with an updated date. Last updated: October 2026.
