What this site does

Deck Planner Lab provides deck-planning calculators and related project-planning content. You do not need to create an account to use the calculators.

Analytics

We use Google Analytics 4 to understand traffic and general site usage. Google Analytics may process information such as device and browser details, pages viewed, approximate location derived from network information, and interaction events. We use this information to improve the site and understand which tools are useful.

Calculator inputs

Calculator values are processed in the browser or as part of normal page rendering. We do not intentionally send the numeric values you enter into calculator fields as custom Google Analytics events.

Affiliate links

Some pages contain affiliate links. When you click one, the destination retailer may receive referral information and may use its own cookies or similar technologies under its own privacy policy. We record a basic outbound affiliate-click event in Google Analytics, such as the merchant, destination link, and placement.

Third-party services

This site is hosted using Vercel and may link to third-party retailers such as Amazon. Those services process data under their own terms and privacy policies.

Changes

We may update this policy when the site, analytics setup, or monetization methods change. The date above will be updated when material changes are made.
