Privacy Policy

1. Introduction

Welcome to Chartixo (“Chartixo”, “we”, “us”, or “our”), accessible at https://chartixo.com. We respect your privacy and are committed to protecting it through our compliance with this policy. This Privacy Policy explains our practices regarding data collection, processing, and protection when you use our free online utility tools.

2. Core Principle: 100% Client-Side Processing

Unlike traditional web services that submit form data to remote servers for computation, the overwhelming majority of Chartixo utilities (including our calculators, unit converters, text formatting tools, JSON validators, and password generators) execute entirely within your browser's local memory using client-side JavaScript.

• We do not transmit, log, or record your numerical calculations.
• We do not read, transmit, or retain your raw text drafts or deduplication lists.
• We do not transmit or store passwords or cryptographic keys generated on our site.
• We do not store financial data, BMI figures, or personal birth dates in any database.

3. Local Storage & Preferences

We use browser Local Storage (localStorage) exclusively to remember your explicit UI preferences, such as your selected theme (Light, Dark, or System). This preference data never leaves your device and is not linked to any personal identifier.

4. Advertising & Third-Party Cookies

Chartixo is supported by online advertising to keep our tools 100% free for everyone. When third-party advertising partners (such as Google AdSense) are active, they may use cookies, web beacons, or similar technologies to serve non-personalized or personalized advertisements based on your prior visits to this website or other websites on the internet.

Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to Chartixo and/or other sites on the Internet. Users may opt out of personalized advertising by visiting Google's Ads Settings (www.google.com/settings/ads) or through the Network Advertising Initiative (www.aboutads.info).

5. Server Log Files

Like standard web infrastructure, our hosting provider (Vercel) automatically logs standard, non-personally identifiable technical information when you request a web page, such as your IP address, browser type, referring page, and timestamp. These server logs are used strictly for technical performance monitoring, security diagnostics, and DDoS mitigation.

6. Children's Online Privacy

Our services are general-audience utility tools and are not targeted toward children under 13 years of age. We do not knowingly collect personal information from children under 13.
