Grow a Garden Calculator

Privacy Policy

How Grow a Garden Calculator handles information — designed to collect as little as possible.

Last updated: September 2026

1. Overview

Grow a Garden Calculator ("the Site") is a free, browser-based tool. The core calculators run entirely on your device. This policy explains what limited information may be processed when you visit the Site or contact us, and what choices you have.

2. Information we do not collect

  • We do not require accounts or registration.
  • We do not collect the numbers you enter into the calculators — those never leave your browser.
  • We do not sell, rent, or trade personal data.
  • We do not use the calculator inputs for profiling or advertising.

3. Information that may be processed

3.1 Contact form messages

If you use the Contact form, we receive the name, email address, topic, and message you voluntarily submit, so we can respond. Do not include sensitive information such as passwords or financial details.

3.2 Technical logs

Like most websites, our hosting provider may record standard server logs (IP address, browser type, referring page, timestamp) for security, abuse prevention, and aggregate traffic statistics. These logs are retained only as long as needed for those purposes.

3.3 Cookies and local storage

The Site stores your theme preference (light/dark) in your browser's local storage. This stays on your device and is not sent to us. If analytics or advertising cookies are enabled on the deployed Site, they will be subject to any consent notice shown at that time.

4. Advertising (Google AdSense)

If display advertising (such as Google AdSense) is enabled on the deployed Site, advertising partners may use cookies or similar technologies to serve ads based on your prior visits to this or 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.

5. Third-party services

The Site may load resources from third parties, such as:

  • Google Fonts (web fonts) — may receive your IP address when the font CSS is fetched.
  • Advertising networks — only if ads are enabled, as described above.

Linked external sites (including social platforms) have their own privacy policies; we are not responsible for them.

6. Children's privacy

The Site is a general-audience tool. We do not knowingly collect personal information from children. If you believe a child has submitted personal data via the contact form, contact us and we will delete it promptly.

7. Data retention

Contact messages are kept only as long as needed to address your request and maintain basic correspondence records, then deleted or anonymized. Server logs follow the retention schedule of our hosting provider.

8. Your rights

Depending on your jurisdiction, you may have the right to:

  • Request access to personal data we hold about you.
  • Request correction or deletion of that data.
  • Object to or restrict certain processing.
  • Lodge a complaint with a supervisory authority.

To exercise these rights, use the contact form.

9. Security

We take reasonable technical measures appropriate for a static website. No method of transmission or storage is 100% secure; avoid sending sensitive data through any web form, including ours.

10. Changes to this policy

We may update this policy to reflect operational or legal changes. The "Last updated" date at the top will change when we do. Continued use of the Site after updates constitutes acceptance of the revised policy.
