Cancelling doesn’t touch your data by itself — it schedules your plan to end, and access continues right up to your current billing period’s close before anything changes.
What this means for you
Selecting cancel doesn’t cut you off immediately. You’ll see “Your plan is set to cancel,” telling you the exact date you keep access until, with a Resume plan button in case you change your mind before then.
Once that date passes, your plan reverts to Free. That change is about which features you can use — it does not, by itself, touch what’s already stored.
What actually controls how long screenshots are kept is your own Screenshot retention setting, under Privacy & data: a nightly job deletes screenshots older than the window you’ve set, on the same schedule whether you’re on a paid plan or not.
We can’t confirm from here what happens to your account or its data over a longer term after a cancellation lapses — if that matters for your situation, ask support directly rather than assume either way.
