I feel like if you ask questions where you have to quote your own words like this, you're basically begging them to be interpreted differently than you intend. I'd be crystal clear about what is being asked.
“Do your apps access the contents of device clipboards and send this information or any modified version of this information off the device without explicit user consent to do-so?”
Remember, all you need to know from them is what they do and when they do it. You don't need or want them to make a judgment call on the legalities or morality or anything else when responding; you can do that yourself later.
To that end, I'd word it like this:
"What are all the situations in which your apps read clipboard contents, and why is it necessary in each case?" (Obviously pasting would be one scenario, to which you'll just nod and move on...)
(And I would ask the same about microphone data, location data, etc. too, not just clipboard contents.)
