Is the schedule maker really free?
Yes, and there is nothing to sign up for. No account, no email address, no trial that runs out, no limit on how many blocks you can add and no watermark on the printout. It is free because it is useful on its own, and because some of the people who use it will eventually want the bookings to arrive by themselves.
Where is my schedule saved?
In this browser, on this device, and nowhere else. Nothing is uploaded to Picktime and there is no account holding it. That means it survives closing the tab and it does not survive clearing your browsing data, and it will not appear on another device. If you want a copy that lasts, use Download CSV or print it.
Can I print it, or open it in Excel?
Both. Print puts the grid on the page on its own, with no navigation, no footer and no form around it. Download CSV gives you one row per block (day, start, end, length and label), which opens directly in Excel, Numbers or Google Sheets.
Can other people book these slots?
Not from here. This is a layout tool, so the week only changes when you change it. If you want people to pick a free time themselves and have it land on your calendar, that is a booking page rather than a schedule, and it is what the free Picktime plan does.
Does it work on a phone?
Yes. Seven days will not fit across a phone screen at a readable size, so the grid scrolls sideways instead of shrinking, and everything else stays where it is. Printing from a phone works too, though a week is easier to read on paper if you send it from a laptop.
