Privacy Policy

This Privacy Policy describes how Fertilizer Dilution Calculator ("we", "us", or "our") collects, uses, and shares information when you visit fertilizer-dilution-calculator.hub2.day (the "Site"). We are committed to protecting your privacy and handling your information transparently.

Information We Collect

Information You Provide Directly: When you use our contact email ([email protected]), you may voluntarily provide your email address and any other information you include in your message. We use this only to respond to your inquiry.

Information Collected Automatically:

  • Calculator Inputs: The values you enter into the fertilizer dilution calculator (e.g., NPK ratios, plant type, water volume) are processed entirely in your browser. We do not store or transmit these inputs to our servers.
  • Server Logs: Our hosting provider automatically collects standard server logs, including your IP address, browser type, referring pages, and timestamps. These logs are used for security, diagnostics, and aggregated analytics and are retained for up to 30 days.
  • Cookies and Local Storage: We use essential cookies and local storage to remember your preferences (such as measurement units) and to ensure the calculator functions correctly. These are strictly necessary and do not track you across other sites. We also use Google AdSense, which may set cookies for advertising purposes (see below).

Google AdSense and Advertising

We use Google AdSense to display advertisements. Google uses cookies to serve ads based on your prior visits to our Site and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our Site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info.

If you are located in the European Economic Area (EEA) or the United Kingdom (UK), we only serve non-personalized ads or obtain your consent for personalized ads via a consent management platform. You can change your consent preferences at any time by clicking the "Cookie Settings" link in the footer.

How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve the Site and its calculator functionality.
  • Respond to your inquiries sent via email.
  • Monitor and analyze usage and trends to improve user experience.
  • Detect, prevent, and address technical issues and security incidents.
  • Display advertisements through Google AdSense.

Legal Basis for Processing (EEA/UK Users)

If you are from the EEA or UK, our legal basis for collecting and using your personal information depends on the specific context:

  • Consent: We rely on your consent for personalized advertising and non-essential cookies. You can withdraw consent at any time.
  • Legitimate Interests: We process server logs and essential cookies based on our legitimate interest in operating and securing the Site, provided these interests are not overridden by your data protection rights.

CCPA/CPRA Notice (California Residents)

Under the California Consumer Privacy Act (CCPA) as amended by the California Privacy Rights Act (CPRA), California residents have the right to:

  • Know what personal information we collect, use, disclose, and sell.
  • Request deletion of personal information.
  • Opt-out of the sale or sharing of personal information.
  • Non-discrimination for exercising these rights.

We do not sell personal information in the traditional sense. However, our use of Google AdSense may involve sharing of device identifiers and cookie data for targeted advertising, which may be considered a "sale" or "sharing" under CCPA. You can opt out by using the "Do Not Sell or Share My Personal Information" link on our Site or by configuring your browser to send a Global Privacy Control signal.

To exercise your CCPA rights, contact us at [email protected]. We will verify your request using information associated with your browser or device.

Service Providers

We may employ third-party companies and individuals to facilitate our Site ("Service Providers"), such as hosting providers and Google AdSense. These third parties have access to your personal information only to perform these tasks on our behalf and are obligated not to disclose or use it for any other purpose.

Data Retention

We retain server logs for up to 30 days. Email correspondence is retained for as long as needed to resolve your inquiry and for our legitimate business records, after which it is deleted. Cookie data retention is governed by your browser settings and the policies of our advertising partners.

Children's Privacy

Our Site is not intended for children under 13 (or 16 in the EEA). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can delete it.

Security

We implement reasonable technical and organizational measures to protect your information. However, no method of transmission over the Internet or electronic storage is 100% secure.

Third-Party Links

Our Site may contain links to other sites not operated by us. We are not responsible for the privacy practices of these third parties. We encourage you to review their privacy policies.

International Data Transfers

Your information may be transferred to and processed in countries other than your own. We ensure appropriate safeguards are in place for such transfers, such as standard contractual clauses, where required.

Changes to This Privacy Policy

We may update this policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
