Short version: We don't collect, store, or transmit your data. Everything stays in your browser.
Startup Domain Search does not operate any backend server or database. We do not collect, store, process, or transmit:
All your data โ search history, favorites, saved sets, settings, and API keys โ is stored exclusively in your browser's localStorage. This data never leaves your device and is not accessible to us. You can clear it at any time via the "Clear All" button in the app or your browser's developer tools.
When you use the tool, your browser makes direct requests to these third-party services:
We have no visibility into or control over these requests โ they go directly from your browser to those services.
We use Google Analytics 4 to collect anonymous usage statistics โ page views, feature usage events (e.g. "search started", "domain available", "favorite saved"). This data is aggregated and does not contain your search queries or domain names. You can opt out via browser extensions such as uBlock Origin or the Google Analytics opt-out add-on.
This tool is fully open source. You can inspect every line of code at github.com/vasilytrofimchuk/domainsearcher-app and verify these claims yourself.
If we ever change our privacy practices, we will update this page and the "Last updated" date above. Given the static nature of this tool, significant changes are unlikely.
