Privacy without surprises.

Calculator and ZIP information

Calculator inputs are used to produce your result. The current public calculators run in your browser. Your ZIP may be stored locally on your device to simplify navigation; our analytics events do not include the full ZIP code.

Basic analytics

We record limited events such as page views, assessment starts, calculator opens and retailer-link clicks. These events help us understand which tools are useful. We honor the browser’s Do Not Track setting in the current implementation.

Accounts and saved data

If you create an account or save a home profile in a future feature, Supabase will process the account and database information required to provide it. We will update this notice before introducing materially different collection.

Service providers

Vercel hosts the website, GitHub stores application code, and Supabase provides database and authentication infrastructure. Retailer links take you to third-party sites governed by their own privacy terms.

Security and retention

We use access controls and encrypted connections provided by our infrastructure vendors. No internet service can guarantee absolute security. Operational data is retained only as reasonably needed for the service, security and legal obligations.
