privacy policy

Last updated: September 2026. We believe in minimal data footprint, transparency, and consumer respect.

1. How your questions are handled

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.

2. Client-side sensor data (Tilt & Motion)

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.

3. Rate limiting & Caching

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.

4. Cookies and Local Storage

We do not use tracking or advertising cookies. We only use browser LocalStorage to remember your preferred UI theme (system, dark, or light).

5. Contact & Inquiries

For any questions regarding privacy or data handling, reach out via Telegram at @shmuelo_o.
