Privacy Policy
Zolunas is privacy-first. Most tools run entirely in your browser. This policy explains what stays on your device and what may leave it.
What stays on your device
Timer state, classroom or name lists, favorites, mute preferences, and tool settings are stored in localStorage by default. We do not upload your lists, notes, or timer titles unless a feature explicitly says so.
Accounts
If you create an account, we store your email, password hash, and a synced preferences blob (favorites, world-clock cities, display settings, and similar). Sessions use an HttpOnly cookie. You can keep using Zolunas as a guest without an account.
Microphone (noise meter)
The classroom noise meter uses your microphone locally in the browser to measure volume levels. Audio is not recorded, stored, or uploaded.
Third-party services
Weather uses wttr.in. When you look up weather, the city or coordinates you search for are sent to that service. No account data is attached.
Optional analytics
Optional product analytics may record anonymous tool events and page paths. They never include names, lists, notes, or free-text titles.
Ads
Reserved ad regions may appear below tools and between content sections. Live ads only load when explicitly enabled. Ads never appear in embed widgets or over timer controls.
