Privacy
The short version: your choices stay on your device.
What is stored
Your ratings, taste sliders and last filters are saved in your browser's local storage under the key tg.v1. A short flag in session storage stops the opening animation repeating within one visit. This data never leaves your browser. Clear your site data to remove it, or use the reset on My teas.
What is not done
There are no accounts, no cookies set by this site, no advertising and no third-party scripts. The site's own code sends nothing about you anywhere. The hosting provider keeps ordinary request logs and aggregate traffic counts, as any web host does.
Sharing
The share link on My teas puts your profile in the part of the address after the hash. That part is not sent to the server when the page loads. It is only shared if you pass the link on.
