Clockfresh tools run in the browser without an account. Timing tools use target timestamps so the display can catch up after browser throttling. Browser alarms and finish sounds still require the page or installed web app to remain available; important alarms should also use a native device backup. Core routes can reopen offline after a successful visit has placed them in the service-worker cache.

## Key facts

- Price: free, no ads, no account, no paid tier.
- Languages: 7 (English at root URLs; es, pt, it, ru, fr, de under locale prefixes).
- Tools: ~25 browser tools plus timing guides and comparison pages.
- Offline: core tool routes reopen offline after one successful online visit (service-worker cache).
- Data: settings and timer sessions stay in the visitor's browser (localStorage); no server-side accounts.
- Accuracy model: countdowns derive from target timestamps versus the real clock, not accumulated ticks.
