Usage data stays on device
The app stores usage and spend history locally. It is built for people who want the signal without creating another hosted analytics account.
Provider calls are scoped
When a provider needs an API key or session credential, the app uses it for that provider's usage endpoint instead of sending it to a separate T4B backend.
The privacy promise is part of the product
AI spend tracking is sensitive because it reveals your tools, work rhythm, and project intensity. The product keeps that data close to the machine where the work happens.
