What happens if you cancel
Nothing is deleted. Your account moves to Free, your history and profile stay readable, and everything resumes if you come back.
Canceling never deletes anything. When your subscription ends, your account moves to the Free plan, with no lockout: your conversation history, your Living Profile, and your Life Vision all stay readable. What changes is what Blue can actively do going forward: the working memory window narrows to 30 days, and the nightly tending, Today guidance, and Reviews pause below their plans. If you return later, Blue picks up where it left off; there is nothing to rebuild. The mechanics of where to cancel (web billing vs app store) are in Managing your subscription.
Canceling is also not the same as deleting your account: deletion is its own explicit step, covered in Exporting and deleting your data, and it is the only thing that removes your data.
For HeartWeave, the same spirit with its own mechanics: access continues through the period you paid for, and its subscription page has the details, including the 30-day money-back guarantee for web signups.
