What does saving forever actually do?
It makes three separate things. The first is a permanent address. Think of it as a bookmark tagged with when the memory was saved and what kind of thing it is. The second is the memory itself, an encrypted copy stored at that address. The third is the key. We manage the key so your saves open in Giant Mind. The address says something is there. The encrypted copy is the thing itself. Your library keeps working as normal alongside both.
Where is the permanent copy stored?
As an encrypted copy at a permanent address. We manage the key. The copy stays at that address after you save it.
Who can read it?
You, the people you authorize, and Giant Mind. We manage the key so we can show you the memory while you are logged in. Then use the recovery kit so you don't rely on Giant Mind to access your memories. The address names the encrypted copy.
What does the address look like?
A short line shown on the memory itself. It names the encrypted copy. Going there gets you the sealed copy. We manage the key that reads it in Giant Mind. The recovery kit holds a copy of that key for you.
What happens if I edit a memory I saved forever?
Nothing changes about the copy already written. Saving again makes a fresh encrypted copy at its own address, and the earlier one stays exactly as it was. Every save keeps the version before it.
Is everything I keep saved forever?
No, and it should not be. Most of what you keep lives in your library, which is searchable, editable, and deletable like any normal app. Saving forever is a deliberate act for the small number of things you would be upset to lose.
