Privacy Policy

Who we are

This website provides free online calculators for indoor farming and hydroponics. References to "we", "us" or "the site" mean the operator of this website. You can reach us using the contact details at the end of this policy.

Information we collect

We do not require registration and we do not ask for your name, address or payment details. The values you type into a calculator are processed locally in your browser and are not sent to or stored on our servers.

We do collect limited, mostly anonymous information automatically when you browse, through third-party services:

• Usage and device data via analytics (for example pages viewed, approximate region, browser type and how you reached the site).
• Advertising-related data and identifiers used by our advertising partners to show and measure ads.
• Standard server/CDN logs such as IP address and request time, used for security and reliability.

Cookies and similar technologies

We and our partners use cookies and similar technologies for analytics and advertising. Essential cookies keep the site working; non-essential cookies are used only where permitted. You can manage your choices through the cookie banner and your browser settings. See our Cookie Policy for details.

How we use information

We use the information described above to operate and secure the website, understand how it is used so we can improve it, and to display advertising that helps keep the calculators free.

Third-party services

We use Google Analytics to measure traffic and Google AdSense to display advertising. These services may set cookies and process data such as your IP address and usage behaviour, and Google may use this data in line with its own policies.

You can read how Google handles data at https://policies.google.com/privacy and manage personalised advertising at https://adssettings.google.com. We do not control how third parties process data once it is collected by them.

Legal basis and your rights

Where the GDPR or similar laws apply, we rely on your consent for non-essential cookies and analytics/advertising, and on legitimate interests for essential operation and security.

You may have the right to access, correct or delete your data, to object to or restrict processing, to data portability, and to withdraw consent at any time. To exercise these rights, contact us using the details below.

Data retention

We retain analytics and log data only for as long as needed for the purposes described here or as required by law. Aggregated or anonymised data may be kept for longer.

Children's privacy

This website is intended for adults and is not directed at children. We do not knowingly collect personal data from children. If you believe a child has provided us with data, please contact us and we will remove it.

International data transfers

Our third-party providers may process data in countries outside your own. Where this happens, those providers are expected to apply appropriate safeguards for international transfers.

Changes to this policy

We may update this Privacy Policy from time to time. The date at the top of this page shows when it was last revised. Significant changes will be reflected on this page.
