About
Pool operation tools made to keep calculations, assumptions, and records understandable.
Created by
TK PoolKit is made by TK Professional Services, LLC. for practical pool operation planning, chemistry review, and recordkeeping workflows.
The site focuses on tools that explain their inputs and show their work, so users can understand the calculation.
Development assisted by OpenAI’s ChatGPT and Codex.
Google Analytics is optional and remains off unless you choose Allow analytics. When allowed, it runs only on PoolKit's public home, About, calculator, and documentation pages. Invitation, Logbook, Properties, admin, and debug pages are excluded.
PoolKit sends Google the public page title and a page address containing only the site origin and path. PoolKit does not enable Google advertising storage or personalization signals.
When you choose No thanks, PoolKit records one anonymous aggregate decline per browser. The consent table stores only the total count—not a visitor ID, page, referrer, account, or time. Like other PoolKit API requests, the web server receives the technical request information needed to serve the request.
Your choice is saved in this browser and can be changed through Analytics Preferences in the footer. See Google's privacy policy for information about Google Analytics data handling.
