If you (temporarily) want to prevent screenshots from being taken, but keep access to your screenshots, you may pause your URL.

You can pause or resume URLs from the main page - in Grid view or List view - by toggling the play/pause icon in front of the scheduled screenshot date/time. If a play icon is shown, you can click that to pause it. If a pause icon is shown, you can resume it.

A paused URL is also indicated with a gray and italic date/time.

Pause / resume multiple URLs

In List view, you can also pause or resume multiple URLs at once: 

• Select the checkboxes for the URLs you want to pause
• Click the "With selected ..." drop-down and select "Pause / Resume" and "Pause" in the second drop-down. Click Apply to confirm.

To resume multiple URLs, do the same as above but select "Resume" in the second drop-down.

Resume URL with backdated timestamp

If you want to resume a URL with a date in the past, it will capture a new screenshot right away and return to the previously set screenshot frequency. 

Example:

A paused URL has a scheduled frequency to be captured every day at 12:00, but it has been 3 months since the last capture and so the old "Next screenshot" time is also 3 months in the past. If you resume the URL, it will capture a new screenshot right away, and it will set the new "Next screenshot" time to 12:00 the next day (or this day if it's still before 12:00 o'clock in your set timezone).
