Frequently asked questions
Is Clockflux free?
Yes. The tracker, the calendar, holiday allowance tracking and the Health view are all free, with no time limit and no account, and they stay free. An optional paid plan, Clockflux Pro, adds cloud sync, exports and a few other extras.
Do I need to create an account?
No. Open clockflux.app and start tracking. An account is only needed for Pro, and you create one by signing in with Google.
Does it work offline?
Yes. On the free plan everything is stored on your device, so Clockflux works with no internet connection at all. You can also install it on your phone or computer — see offline use, installing and backups.
Where is my data stored?
Without an account, only in your own browser on your own device — it is never sent anywhere. With Pro, your name, email and time entries are also stored on our servers in the EU so they can sync between devices. The privacy notice has the full details.
Can I use it on my phone and my computer?
Yes, Clockflux runs on both. On the free plan each device keeps its own data, but you can move it across with a backup file. With Pro, cloud sync keeps every device you sign in on up to date automatically.
What happens if I forget to check out?
Clockflux closes the session for you at 21:00 that day (or at the end of the day, if you checked in later) and flags the day in the calendar so you can set the right time. See tracking your hours.
I don’t work Monday to Friday. Can I change my working days?
Yes — choose your weekend days in Settings → Weekend, for free. The default working day is 8 hours; setting your own daily target is part of Pro.
Can it track holiday and sick days?
Yes. Mark days in the calendar as personal holiday, sick leave, a public holiday or unpaid leave, as whole or half days. Only personal holiday counts against your annual allowance. See calendar and days off and holiday allowance.
Does it calculate my overtime?
Yes. Clockflux compares each week with your target, taking days off into account, and keeps a running overtime balance with a chart — see overtime and work/life balance. For a one-off sum, try the overtime calculator.
Can I export my hours for a timesheet?
With Pro you can export your entries as CSV, a PDF report for any date range, or an .ics calendar file. On the free plan you can download a backup of your data, and the totals are shown in decimal hours, the format most timesheets ask for.
Is Clockflux for teams or employers?
Clockflux is a personal tracker: it records your own hours, for you. There is no manager view and nobody else sees your data.
How do I cancel Pro or delete my data?
Cancel Pro yourself at any time from Settings; you keep it until the end of the period you have paid for. You can delete your account, and everything we hold for you, from Settings too. Without an account, your data is only in your browser — clearing the site’s data removes it. See the refund policy and pricing.
