Earlier quoted context omitted.

you can check on https://www.cipherwill.com/how-it-works just select "I understand how encryption works"

> you can check on https://www.cipherwill.com/how-it-works just select "I understand how encryption works" This is very high-level and doesn't actually answer the question asked. I also don't see anything here regarding the decentralized blockchain storage you mentioned in another comment. How does that fit in here?

Private keys are generated locally from your security factors during setup. We’ll ensure the "How It Works" section is more detailed and add pages for live monitoring that display decentralized storage usage and access details.

What happens if Cipherwill goes out of business before my death? The whole thing goes kaput and I’m stuck figuring out a new solution?

If Cipherwill goes out of business, we'll make sure to share your data with you so you won't be stuck without a solution. Plus, Cipherwill's data is hosted on blockchain, which helps ensure we won't go out of service.

Where an how is user data stored? Do you use cloud providers/SaaS and in which jurisdiction? Considering legal requests for user data are being served, location/jurisdiction for both CipherWill and its servers are important and I don't seem to find this mentioned. Aside, but I don't think I'm alone in considering this a non-starter combined with the whole stack including the client being closed-source. Fresh advertis…

We’re committed to transparency and are exploring ways to improve our documentation, including our Terms of Service and Privacy Policy. Your input is valuable, and we’ll take it into account as we develop the platform further.

Which blockchain is user data stored on?

We'll be adding pages for live monitoring that display decentralized storage usage and access details very soon

What’s the scenario for a will that expires? Also, I can see the use of commutative encryption for the time capsule support but I’m not seeing where homomorphic encryption fits in.

we'll notify your beneficiaries and ensure that your data is accessed by them. We employ homomorphic encryption in cases where beneficiaries choose to switch/update/upgrade existing factors without notifying data owner.

I'm not sure there's anything a service like this could do to assure me that (1) I can trust them, and (2) that they can actually make the UX of this meaningfully better, without compromising security fundamentally. For now, I'm rocking: * yubikeys pre-provisioned with keys given to select family members * sops to encrypt my "will" to those keys * sops-encrypted file hosted on google drive, pre-shared to select famil…

Sheesh; no excuse not to back up your BIP-39 mnemonic phrases using SLIP-39 (Shamir secret sharing):

Furthermore, you can use the same App to SLIP-39 any arbitrary 128-, 256- or 512-bit key in a way that your family can combine their data to recover.

I mean, just a regular will can cover all of this for you. For real assets listed on the page such as real estate, investments, etc, a will is the only real way to sort those out actually (unless you want whatever the default proceeding is where you're from). If you're the inheritor of someone, you can't just go and transfer their bank contents to your own account. As for things such as files, pictures, etc, you can…

I'm with you. The whole time I was reading the copy on the site, I kept thinking "What's wrong with a normal will and a lawyer?" Even crypto can be handled via a will if you're smart about it.

I have a document that contains all of our subscriptions, our key information, contacts, last will, etc, that I update monthly, put on a thumb drive, and hide in a place my wife knows. I can't encrypt it because she isn't tech savvy enough, but physical obscurity is enough for me. I encrypt the copy on my PC. I also print out a copy and have it in our lockbox.

In addition, we have a shared password manager with a Yubikey that she has access to for MFA, and she knows the password.

If we both die at the same time, one of my close friends knows where all of this is and can provide to the lawyer handling our kids provenance.

I don't have much crypto because I think it's by and large a scam market, but it's on a drive that is described in the document on the USB.

At the end of the day, the things that are important to me are written down as physical copies. We print off photos and put them in photo books. My favorite music is on CDs.

All that said, I see the real benefit in a service like this for the older generation like my in-laws. I've had multiple conversations with him about the passwords to all their online accounts and all their critical information, and all their passwords are just stored in his Google Chrome password manager. My MIL doesn't know the password to his Chrome account. If he dies first, she's going to have a helluva time getting access to everything. So if he could sign up to a service like this that we could trust, it would be immensely helpful.
