Your privacy matters. Here is what we collect (very little) and what we do with it.
We don't require sign-up or personal data. This tool runs entirely in your browser: your roster and settings are stored locally in your browser's localStorage and never sent to a server.
☁️ Optional cloud (your choice). If you sign in with Google (the "Sign in / Create account" button), your roster is also stored in Google Firebase, tied to your Google account (we only use your email as an identifier; we access nothing else). You can sign out or delete your cloud data from the same panel at any time. If you never sign in, nothing leaves your device.
We use aggregated, anonymous analytics to count visits (without identifying you).
If we display ads, their providers (e.g. Google) may use cookies to personalize them; you can manage this in your Google account's ad settings (adssettings.google.com) and, where applicable (EU/UK), you'll see a cookie notice.
We do not sell or share personal data (we don't have any).
