Calculation inputs

The calculators run in your browser. Dimensions, PPFD, electricity rates and calculation results are not submitted by these tools to a server. We do not save them to browser storage.

Site analytics

This site loads an Umami script to measure page views and outbound affiliate-click events. Events identify the product reference, not the values entered in a calculator. Do Not Track is enabled for the script.

Google Search Console provides aggregate search-performance reports. Cloudflare processes requests to deliver and secure this site.

External links

Manufacturer, source and Amazon links take you to other sites whose privacy practices apply there. Supplied product images load from Cloudflare R2 storage. Loading an image sends a request to that service. Customer review text is not embedded. These images are distinct from locally hosted AI-generated editorial illustrations.

Contact and retention

Analytics is self-hosted at umami.ryanjowens.com. It records visited pages, referrers, device/browser information, approximate location and product-click events. The tracker does not use analytics cookies. Analytics records are retained until manually deleted; no automatic deletion period is configured for this website.
