This looks quite interesting and quite topical to a discussion I had just yesterday during an interview. I almost clicked the installer but hesitated. A link that discusses the impact and especially any issues if/when your product was uninstalled would be reassuring.
with the answer to your question (and more), but I'll answer here too:
We don't modify the data in your Gmail account, so if you try Draftable, then uninstall it, your Gmail account won't be altered. Furthermore, if you disable Draftable before uninstalling it, we'll delete our index and revoke our access to your account.
