Last updated: September 2026. We believe in minimal data footprint, transparency, and consumer respect.
When you ask a question, the text is transmitted to our backend API to shortlist relevant items and query the TypeSafe Jev decision router. Questions are evaluated solely to calculate calibrated match probabilities. We do not sell your queries or build advertising profiles.
Physical motion features (device tilt and shake) run strictly inside your browser through the DeviceOrientation and DeviceMotion APIs. Sensor values are fed directly into the client-side Matter.js physics engine to shift gravity. This data never leaves your device and is never logged or sent to any server.
To protect the service against abuse and provide instantaneous responses, we use an in-memory sliding window rate limiter based on hashed IP addresses, and an in-memory LRU cache for identical queries. IP logs are transient and automatically purged.
We do not use tracking or advertising cookies. We only use browser LocalStorage to remember your preferred UI theme (system, dark, or light).
