Privacy Policy

Welcome to ZechKit (“we”, “us”, or “our”), accessible at https://zechkit.com. ZechKit provides a diverse suite of free, web-based calculators, unit converters, formatting utilities, document tools, and educational engineering guides designed for everyday productivity.

This Privacy Policy explains what information we and our third-party service providers may collect, how that information is used, how your browser interacts with our tools, and what rights and choices you have regarding your personal data.

Please read this Privacy Policy carefully. By visiting or using ZechKit, you acknowledge the data practices described herein. If you do not agree with this policy, please discontinue use of our website.

A foundational architectural principle of ZechKit is client-side computation. Most of our online tools are programmed in JavaScript, HTML5 APIs, and WebAssembly to perform operations directly inside your web browser.

When you use our tools:

• Unit Conversions: Numerical quantities and unit types you select are computed locally in browser memory.
• Calculators: Financial calculations, mortgage math, age calculations, and date intervals are evaluated client-side.
• Text & Code Tools: Text you format, CSV files you inspect, JSON you validate, and regex expressions you test are parsed in your browser.
• Color & Media Tools: Color picker codes, image compression routines, and PDF merges are executed on your device via client-side libraries.
• Tool Preferences: Settings such as selected default units or dark/light display preferences are stored locally on your machine.

No Server Uploads for Tool Data: Your calculator inputs, text inputs, file contents, and computed results are processed locally and are not intentionally transmitted to, saved on, or analyzed by ZechKit web servers.

We use Google Analytics, a web analysis service provided by Google LLC (“Google”), to help us understand aggregate traffic trends and improve user experience across ZechKit.

Google Analytics uses cookies and tracking code to collect general telemetry such as pages visited, time spent on pages, browser and operating system details, approximate geographic location (at country/city level), and referring traffic sources.

We configure Google Analytics with IP anonymization features where available, masking a portion of your IP address before storage. However, we do not claim that all telemetry is completely anonymous in every technical sense, as Google may correlate technical signals in accordance with its own systems and policies.

To learn more about how Google collects and processes data, visit the Google Privacy & Terms Policy ↗. You can prevent Google Analytics from tracking your visits across the web by installing the official Google Analytics Opt-out Browser Add-on ↗.

We display digital advertisements on ZechKit through Google AdSense and its certified advertising partners to help fund our free server and maintenance expenses.

Google and third-party advertising networks use cookies, web beacons, and similar technologies to:

• Deliver advertisements to your browser when you visit our site.
• Measure advertising performance, impressions, viewability, and user clicks.
• Help prevent advertising fraud, click abuse, and invalid traffic.
• Personalize advertising content based on your prior visits to this site or other websites across the web, where permitted by law and your consent settings.

Consent & Personalization: The behavior of advertising served to you depends on your location, your browser settings, and your choices made in our cookie consent banner. In regions where consent is legally required (such as the EEA, the UK, and Switzerland), personalized advertising is only shown if you grant consent; otherwise, non-personalized contextual ads may be served.

You can learn more about how Google uses information from sites that use its services, manage your advertising preferences, or opt out of personalized ads by visiting:

• Google Privacy & Terms ↗
• Google Ad Settings (Manage Ad Personalization) ↗
• Digital Advertising Alliance (DAA) Consumer Choice ↗
• Network Advertising Initiative (NAI) Opt-Out Tool ↗

ZechKit integrates with select third-party service providers to deliver essential website functionality, analytics, and advertising. Each provider processes data independently in accordance with its own privacy policy:

We encourage you to review the privacy policies of these third parties to understand their data collection, handling, and opt-out procedures.

Some pages, blog articles, and tool recommendations on ZechKit may contain affiliate links.

If you click on an affiliate link and subsequently make a qualifying purchase, ZechKit may receive a referral commission from the merchant at no additional cost to you.

Affiliate partnerships do not increase the price you pay for any product or service. Our editorial content and tool suggestions are based on perceived usefulness, practical value, and relevance to our visitors.

Visitors may voluntarily submit feedback, tool requests, bug reports, or inquiries through our contact form or direct email.

The information collected through these communications typically includes:

• Your name
• Your email address
• The subject line and text content of your message

We use this information solely to review, respond to, and resolve your specific inquiry. We do not intentionally sell, rent, or repurpose contact form submissions for unsolicited commercial marketing.

We implement reasonable technical and administrative security measures designed to protect information under our control against unauthorized access, loss, misuse, or alteration.

All communication between your web browser and ZechKit is encrypted using modern HTTPS / TLS (Transport Layer Security) protocols. Furthermore, because tool calculations execute in your local browser, sensitive inputs do not traverse the public internet to our servers.

However, no electronic transmission over the internet or method of digital storage can ever be guaranteed to be 100% secure. While we strive to employ commercially acceptable safeguards, we cannot guarantee absolute security.

We retain personal information only for as long as reasonably necessary to fulfill the purposes for which it was collected, to maintain our services, resolve disputes, enforce our agreements, or comply with applicable legal obligations.

• Contact Inquiries: Communications received via contact forms or email are retained only as long as required to assist you and maintain proper business records.
• Tool Calculations: In-browser calculations are stored in temporary browser memory and are discarded as soon as you close or refresh the tab.
• LocalStorage Data: Preferences saved in your browser's LocalStorage remain on your device until you clear your browser cache or reset tool settings.
• Analytics & Advertising Data: Data processed by third-party services is retained according to their standard retention policies.

Depending on your country, state, or jurisdiction of residence, you may possess specific legal rights regarding your personal data. These rights may include:

To submit a privacy inquiry or exercise any applicable rights, please contact us at zechdev01@gmail.com. We will review and respond to your request in accordance with applicable privacy laws.

If you reside within the European Economic Area (EEA), the United Kingdom, or Switzerland, the processing of your personal data is subject to the General Data Protection Regulation (GDPR) or equivalent local privacy enactments.

Our legal bases for processing information include:

• Consent: When you consent to optional cookies, analytics, or advertising tags through our Usercentrics consent banner. You may adjust or withdraw your consent at any time.
• Legitimate Interests: To operate, secure, troubleshoot, and optimize our website, protect against fraudulent activity, and respond to incoming inquiries.
• Legal Compliance: When processing or retention is required by applicable statutory regulations.

EEA, UK, and Swiss residents also hold the right to lodge a complaint with their local data protection authority if they believe our processing of their personal data violates applicable regulations.

Under the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA), California residents have specific statutory rights regarding personal information:

• The right to know what categories of personal information we collect, use, and disclose.
• The right to request the deletion of personal information collected from you.
• The right to correct inaccurate personal information.
• The right to non-discrimination for exercising your privacy rights.

No Sale of Personal Information: ZechKitdoes not sell personal information for monetary compensation. However, the deployment of third-party advertising cookies may be classified as “sharing” under California law for cross-context behavioral advertising. You can opt out of third-party advertising cookies using our cookie banner or through the opt-out links listed in Section 6.

To submit a California privacy request, please contact us at zechdev01@gmail.com.

ZechKit is a general-audience website offering utility calculation and conversion tools. Our services are not directed toward children under the age of 13 (or under 16 where required by applicable local law), and we do not knowingly collect personal information from children.

If a parent, guardian, or educator believes that a child has voluntarily provided personal information to us through our contact form, please notify us immediately at zechdev01@gmail.com. Upon verification, we will promptly delete such information from our records.

ZechKit is accessible internationally. If you access our website from outside the region where our hosting servers or third-party service providers are situated, please note that information may be transferred to, stored, and processed in jurisdictions where data protection laws may differ from those of your home country.

Our third-party providers (such as Google and Cloudflare) implement recognized cross-border transfer mechanisms, including Standard Contractual Clauses (SCCs) approved by regulatory bodies, to safeguard international data transfers.

Our website may contain hyperlinks to external third-party websites, documentation, software repositories, or merchant partners.

We do not control and are not responsible for the content, security measures, or privacy practices of external websites. We encourage you to review the privacy policies of any third-party websites you visit.

We may update this Privacy Policy from time to time to reflect changes in our tools, technology, operational practices, third-party integrations, or applicable legal requirements.

Whenever updates are made, we will revise the “Last Updated” date at the top of this page. Any changes become effective immediately upon posting. We encourage you to review this policy periodically to stay informed about our privacy practices.
