Opencode also have a ZDR (zero data retention) deal with them – if I recall correctly, that's not something you can enable as an individual DeepSeek subscriber.
Unfortunately, all mentions of ZDR have silently been removed from the OpenCode Go page today.
I really like OpenCode - BUT: there is a loophole the size of Portugal in that ZDR language. All they say is that their providers follow a ZDR policy. I haven’t found anything promising that OpenCode themselves don’t retain Go usage data. Something to be mindful of.
