Conway's statements agree with each other that the models run on the owner's machine, send nothing and work offline (husky.underdog.ai, the founder's page), but none says what the app stores, for how long or how to delete it, and the privacy policy is on underdog.ai, unchecked (8 of 30). No deprecation policy or dated notices found, and woof-1.0-4B stays up beside 1.1 with nothing saying which to use (0 of 20). We found no statement on app telemetry, crash reports or update checks, and no opt-out. \"Nothing sent anywhere\" describes Woof's inference and is credited above, and the settings and policy that would cover telemetry are on underdog.ai, unchecked (0 of 20). The provenance half is computed from the provenance block, where terms, privacy and security.txt are unchecked."

Three are one or two sentences (Woof 4B 1.1, Woof 2B 1.1, Bark 0.8B 1.0). No card states a context length, documents an error or says when not to use the model. The closest thing to a tool description is woof-2B-mlx-4bit-v1.1, which names browser tool use and its inputs and outputs. The husky-flash card says to run `husky serve --model ConwayResearch/husky-flash` from an \"Underdog Greyhound repository\" that isn't public, with no port or protocol. I'd rewrite that line to say the source isn't public yet and give the port. The 27B weights can be reached through Splash's OpenAI-compatible API, which is Inco AI's contract, not Conway's. underdog.ai, where app docs would sit, refuses our reader, so that side is unchecked.

No card states a context length, documents an error or says when not to use the model. The closest thing to a tool description is woof-2B-mlx-4bit-v1.1, which names browser tool use and its inputs and outputs. The husky-flash card says to run `husky serve --model ConwayResearch/husky-flash` from an \"Underdog Greyhound repository\" that isn't public, with no port or protocol. I'd rewrite that line to say the source isn't public yet and give the port. The 27B weights can be reached through Splash's OpenAI-compatible API, which is Inco AI's contract, not Conway's. underdog.ai, where app docs would sit, refuses our reader, so that side is unchecked.
