Contrary to popular belief, DeepSeek really aren't interested in your prompts.
What I see is https://cdn.deepseek.com/policies/en-US/deepseek-privacy-pol...
They do not have a specific exclusion for API use.
I know Z.ai has an exclusion for API use. It's widely reported Deepseek doesn't.
To the open platform terms (i.e. for API use): https://cdn.deepseek.com/policies/en-US/deepseek-open-platfo...
The standard terms includes clause 4.3 which grants them the right to retain inputs and outputs for training purposes, and this is missing from their API terms. The standard terms also cover the right to opt out (which you can do from your user settings). No such opt-out exists on the API because it isn't applicable.
I'm writing a program I personally need, but I would be happy if there existed something like it already, if someone else vibecoded a better version of it than mine, or if DS got better at vibing this kind of thing.
what proof do you have, that they don't train on your data?
they can say they don't, but I don't see any way for you to confirm it.
with how these companies operate currently, I won't be surprised, if they say that one of agents "mistakenly" did that already..
It actually was awesome in the early Facebook days where you could have your entire phone contacts and other apps filled out with a profile picture and Birthday by connecting them together. But that relationship has been completely abused, privacy has been invaded, and my data has been sold to multiple companies.
The goal going forward is to keep that data private. If your company can't survive without it then I hope your company goes out of business
