Privacy

No ads, no accounts, no cookies, no third-party trackers. This page describes exactly what is measured and what never leaves your browser.

The short version

Idiomingo counts anonymous usage — which kinds of page get read, whether people finish the daily challenge, whether anyone downloads a share card. It does not store your IP address, your browser's user agent, the pages you came from, or anything you type into the search box. There is no way to identify you from what is collected, and no way to link two of your visits together.

What is measured

Interactions are recorded as anonymous events, held in this site's own database. Each event carries:

the event name (for example "page viewed", "daily challenge completed", "share card downloaded");
a random session identifier stored in your browser's sessionStorage under idm_sid. It is generated fresh for each tab and destroyed when you close it. It is never linked to you;
the page path (never the query string);
the kind of page — home, collection, entry, hub, blog, search;
for entry pages, which collection and which entry;
a single true/false flag for whether this browser has visited before, backed by a localStorage key called idm_seen that stores nothing but the fact that you have been here. It is a boolean, not an identifier: it lets us count how many visits are returning ones without holding anything that could connect two sessions;
for searches, the number of characters typed and the number of results — never the text.

What is never collected

Your IP address.
Your user agent or device fingerprint.
The full address of the page you arrived from — only the host, and only for clicks leaving the site.
What you search for.
Your favorites, your quiz answers, or your streak.
Anything at all that identifies you.

Do Not Track

If your browser sends a Do Not Track signal, no events are recorded at all. Traffic identified as a search-engine crawler or an automated tool is likewise ignored.

Events are kept for 180 days and then deleted.

What stays on your device

These are stored in your browser and are never transmitted anywhere. Clearing your site data removes them.

Key	What it holds
`proverb-favorites`	Entries you have starred.
`proverbs-dark-mode`	Your light/dark preference.
`focus-lang`	Your chosen language filter.
`pb_cache_v6`	A short-lived copy of the collection, so the site works offline and loads faster.
`daily-quiz-streak`, `daily-quiz-best-streak`, `daily-quiz-last-completed`, `daily-quiz-today-result`	Your daily challenge streak and today's result.

Other services this site uses

Vercel hosts the site, and Vercel Analytics and Speed Insights record aggregate page views and page-speed measurements. Both are cookieless and neither builds a profile of you.
Supabase stores the collection and the anonymous events described above.
Google Fonts serves the site's typefaces, flagcdn.com serves the small flag icons, and some illustrations are served by Unsplash. Loading a file from another company's server necessarily reveals your IP address to that company — that is how the web works, and it is worth knowing. Serving these from our own domain instead is on the list.
