I built BackupDiary to scratch my own itch because I was afraid if something happened to me, what would happen to my bank account, online subscriptions, passwords (in case my family needed them), etc?

Most of us also have a legal will to help our family, but I think most everyday things are left out. So, this is an informal digital will. It works like a dead man's switch.

The idea is simple:

1. Create a note and keep it updated. It is stored encrypted using an AES 256-bit key.

2. Add up to 5 recipients

3. Check in once every 30, 60, or 90 days. You can pick your check-in period.

4. If you don't check-in, the note is decrypted and sent as a PDF file to every recipient.

What do you think? I'd love to answer any questions and concerns.
