LLM thinking (“the app”) is an iPhone chat app. The language model runs on your device. There is no app account and no chat server.
The app does not create an account, does not analytics-track usage, and does not send your chat text to us. We do not operate a backend that stores conversations.
Chat threads and the downloaded model file stay in the app’s sandbox (Application Support). Deleting the app removes them.
The app uses the network to download a model file (GGUF) from Hugging Face when you choose a model. Hugging Face can see that download (for example your IP address) under their own policy. After the file is on the device, generating replies does not require a server.
If you skip or cancel a download, nothing else is uploaded by the app.
If you use the support form on this site, your email and message are sent to us so we can reply. The app itself does not send that form.
