“Yes. You can create a memorial page and keep it online for free, for as long as you want. There is no time limit and no card needed to start. If you later want more storage or extra features there are paid options, but a complete, private memorial costs nothing.”
“No. Creating a memorial, inviting people to contribute and importing from Facebook are free, with the core features included. Paid plans add more storage and unlimited editors, but you only upgrade if you want them.”
“Storage and editors. Free gives each memorial 1 GB and up to 3 editors besides you, with pending invitations counting towards the 3, and includes Facebook import.”
“If you downgrade from Keep to Free, the page stays live and nothing is deleted. If a memorial is using more than the free 1 GB, new photos, videos and recordings for it are paused until space is made or Keep is restarted. Rejecting or removing items frees their space.”
