Privacy Policy & Zero-Tracking Architecture

We respect your digital sovereignty. Paint Undertones Guide collects zero personally identifiable information (PII) and deploys zero surveillance telemetry.

Zero Cookie Tracking & LocalStorage Swatch Persistence

Paint Undertones Guide operates with a strict zero-tracking architecture. All swatch selections, room calculations, and comparison palettes persist exclusively in client-side local storage with zero third-party data tracking.

When you explore paint swatches, compare Delta-LRV values, or calculate gallon requirements in our workbench, those preferences are stored strictly in your browser's private Web Storage API under the key pu_swatch_tape_v1. This data never traverses an external network, is never synchronized to a remote server, and can be purged instantly by clearing your browser cache.

Data Disclosure & Third-Party Telemetry Absence

Our digital platform does not embed invasive behavioral advertising pixels, social media tracking beacons, or cross-site tracking scripts. Server access logs capture only standard, ephemeral HTTP connection headers required for Cloudflare DDoS mitigation and network edge delivery.
