Privacy Policy
This Privacy Policy explains what information PlantLightIndex may receive when you use the website, submit the contact form, follow external links, or interact with services used to operate and measure the site.
Information you provide
You can use the core PlantLightIndex content and calculators without creating an account. When you use the contact form, you may provide your name, email address, inquiry topic, a relevant page or source URL, and the message you choose to send. We use this information to review and respond to your inquiry, investigate corrections, and maintain relevant correspondence.
Please do not send sensitive personal information through the contact form. Evidence and taxonomy corrections usually need a source URL and technical context rather than personal data.
Contact form processing through Formspree
PlantLightIndex uses Formspree to receive and process contact-form submissions. When you submit the form, the information in the form is transmitted to Formspree so the message can be delivered and managed. Formspree may also process technical information associated with the request as part of operating, securing, and protecting its form service.
Formspree operates as an external service provider and applies its own privacy and security practices. You can review Formspree's security and privacy information before submitting the form.
Calculator inputs and site tools
PlantLightIndex calculators use values such as PPFD, light duration, plant selection, window conditions, and grow-light settings to generate results. The site is designed so these inputs do not require an account. PlantLightIndex does not intentionally use calculator inputs to identify you personally.
Normal hosting, browser, security, or analytics systems may still receive technical request information when a page or interactive tool loads.
Hosting, server logs, and technical information
The website is hosted using third-party infrastructure. Hosting and security systems may automatically process information such as IP address, browser type, device information, requested URL, referring page, timestamps, and diagnostic or security logs. This information can be used to deliver the website, detect abuse, investigate errors, and maintain performance and security.
Analytics and performance measurement
PlantLightIndex may use analytics or performance tools to understand how pages are discovered and used. Depending on the service and configuration, these tools may process device, browser, referral, page-view, approximate-location, or interaction data. Analytics information is used to improve content, navigation, technical performance, and site usefulness.
Where a consent mechanism is legally required for a particular analytics or advertising technology, it should be presented before that technology is activated for the affected visitor.
Cookies and similar technologies
PlantLightIndex and services used by the website may use cookies, local storage, or similar technologies for essential functionality, security, analytics, preferences, or measurement. The exact technologies can change as the site evolves. Browser controls can be used to delete or restrict cookies, although blocking essential storage may affect some functionality.
Affiliate links and third-party commerce
PlantLightIndex may include affiliate links to grow lights or other relevant products. If you follow an affiliate link and make a qualifying purchase, PlantLightIndex may earn a commission at no additional cost to you. The retailer, manufacturer, or affiliate network you visit may use cookies or other tracking methods to attribute referrals, process transactions, prevent fraud, and measure commissions under its own privacy policy.
Affiliate relationships do not change the evidence fields, PPFD measurements, source provenance, confidence labels, or calculator logic used by PlantLightIndex.
External links
PlantLightIndex links to universities, botanical institutions, scientific publications, manufacturers, retailers, and other third-party websites. Once you leave PlantLightIndex, the destination site's privacy practices apply. We do not control how an external website collects, stores, or uses information.
How long information may be retained
Contact submissions and related correspondence may be retained for as long as reasonably needed to respond, investigate a correction, maintain a useful record of a data issue, meet operational requirements, or resolve abuse and security concerns. Third-party providers may maintain their own retention periods.
Data security
Reasonable technical and organizational measures are used to protect the website and the information handled through it. No internet transmission or storage system can be guaranteed to be completely secure, so users should avoid sending information that is unnecessary for the purpose of the inquiry.
Children's privacy
PlantLightIndex is a general horticultural information website and is not designed to collect personal information from children. If you believe a child has submitted personal information through the contact form, use the contact page to request review of the submission.
Your privacy choices and requests
Depending on where you live, applicable privacy law may give you rights relating to personal information, such as requesting access, correction, deletion, or information about how data is processed. Use the contact form for a privacy-related request and provide enough detail to identify the relevant correspondence.
Changes to this policy
This policy may be revised when the website changes its forms, analytics, hosting, advertising, affiliate, or other data-handling practices. The version published on this page is the policy that applies to the current site configuration.
