@billymach4 in addition to not sharing PII in chats, you can ask Claude to build an unpopulated spreadsheet for download to help plan for Roth Conversion or optimal retirement age. I recently had it build a model with variables on how much debt to income to guide a HELOC max to propose.Then download and populate with your actual data on your local PC to avoid sharing with the cloud
I would use Sonnet or higher so it considers all the tradeoffs and scenarios. Once built, ask Claude to fill in a hypothetical example so you can test the values and scenarios before download.
P.S I also don't trust the IRS etc. Sadly the government knows too much already.
Not perfect but I consider Anthropic the lesser of many evils. My point is that they apply IT cyber to avoid getting hacked. I trust they are trying to do the right thing when it comes to privacy because the company has an ethical culture.
I am wary of small accountancies and CFAs who do not have similar funding to build cyber defenses.
