Privacy Policy

2.1 Information You Provide

We do not collect or store any inputs you enter into our tools. All tool processing (hashing, encoding, TOTP generation, JWT decoding) happens exclusively within your browser. Your data never reaches our servers.

Specifically, we do not:

• Require account registration or login.
• Log tool inputs or outputs.
• Store secret keys, passwords, tokens, or any other sensitive data.
• Sell or share user data with third parties for marketing purposes.

2.2 Automatically Collected Information

When you visit Copynix, standard web server logs and analytics services may automatically collect certain non-personally-identifiable information, including:

• Browser type and version.
• Operating system.
• Referring URL (the page you visited before arriving at Copynix).
• Pages visited on Copynix and time spent on each page.
• Approximate geographic location (country/region level, not precise location).
• Device type (desktop, mobile, tablet).

This information is used in aggregate form to understand how users interact with the site, improve tool design, and diagnose technical issues.

2.3 Local Storage

Certain features use your browser's localStorage to store data locally on your device. For example, the TOTP tool may store your added accounts locally, and the password tool may retain a history of generated passwords. This data:

• Is stored entirely on your device, not on our servers.
• Is never transmitted over the network.
• Can be cleared at any time via your browser settings (Settings → Privacy → Clear site data).
• Is not accessible to us or any third party.

3.1 Essential / Preference Cookies

We store your theme preference (light/dark mode) and language preference in localStorage. These are strictly necessary for the site to function as you expect and are not used for tracking.

3.2 Analytics Cookies (Google Analytics)

We use Google Analytics (GA4) to understand how visitors use our site. Google Analytics sets cookies to track page views, session duration, and user flows. This data is collected in aggregate and does not personally identify you.

Google Analytics data retention is set to the minimum period (2 months for user-level and event-level data). You can opt out of Google Analytics tracking by:

• Installing the Google Analytics Opt-out Browser Add-on.
• Enabling "Do Not Track" in your browser settings.
• Using a privacy-focused browser or ad blocker.

3.3 Advertising Cookies (Google AdSense)

We display ads served by Google AdSense. Google may use cookies to show personalized ads based on your browsing activity across the web. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to Copynix and/or other sites on the internet.

You can opt out of personalized advertising at adssettings.google.com.

Google AdSense also uses the DoubleClick cookie (and similar technologies) to serve ads across the web. You can learn more about how Google uses data when you visit partner sites at: google.com/policies/privacy/partners.
