xinghzhe.com is a European software research and product lab dedicated to minimalist design, privacy-first engineering, and immersive interaction. Headquartered in Stirling, United Kingdom, we craft local-first iOS and macOS utilities, programmatic audio systems, and visual design frameworks for users who believe technology should serve experience — not the other way around.

// what we engineer
Three disciplines. One philosophy.
We refuse to treat software as a delivery vehicle for advertising. Instead, every xinghzhe product is built from the ground up around three principles: minimalism, privacy, and experience. The result is software that feels quiet, deliberate, and alive.
Programmatic Generation
Procedural audio synthesis, procedural visual systems, parametric interaction models. We replace static presets with living algorithms that produce infinite, organic variations on every run.
- Procedural audio engines
- Real-time generative shaders
- Parametric UI morphing
- ML-driven content synthesis
Privacy-First Architecture
Every byte a user creates is processed on-device. No third-party SDK quietly phones home. No background telemetry. We build privacy as a runtime invariant — not a checkbox.
- On-device machine learning
- Zero-knowledge vault design
- Granular consent controls
- GDPR-aligned data flows
Immersive Interaction Design
Interfaces that breathe. Motion that carries meaning. We design for the moment after the first impression — when a product becomes a quiet companion rather than a chore.
- Hand-tuned micro-animations
- Reduced-motion accessibility
- Zen, calm visual language
- Adaptive dark / light / custom
// on the App Store
A growing family of local-first utilities.
Six product lines, all published on the App Store under the xinghzhe label. Each app delivers a focused, automation-rich experience with the strict "data never leaves the device" guarantee.
Collectible Index
Dynamic valuation engine for collectors. Track, compare, and forecast the market value of any collection in real time.
Posture Studio
Body posture training data recorder with on-device motion capture. Capture sessions, track progress, and own every byte of data.
Estate Vault
Encrypted local vault for house documents, deeds, certificates and proofs of ownership. AES-256, biometric gating.
Fragment
Inspiration fragment classification and storage. Capture fleeting thoughts, organise by mood, by project, by life chapter.
Cyclical Budget
Periodic budget control engine with recurrence rules, allocation envelopes and forecasting. No bank connection, no syncing.
// under the hood
Built like an instrument.
Built like an instrument.
Documented like a treaty.
Every line we ship is reviewed by at least two engineers, every privacy decision is documented in the open, and every API surface is published with its threat model. We believe great software is the result of slow, deliberate craftsmanship — not fast iteration on surveillance.

// operating principles
Five rules we never break.
01
Locality
If it can run on-device, it stays on-device.
02
Minimalism
Every pixel earns its place. Every word earns its sentence.
03
Craft
Slow iteration, deep review, written documentation.
04
Transparency
Threat models, audit reports and policy diffs published openly.
05
Empathy
Software that asks less of you, not more.
06
Longevity
We design for the decade, not the quarter.
07
Compliance
GDPR, UK-GDPR, CCPA, COPPA, PIPL — by default.
08
Beauty
Quiet interfaces. Calm motion. A sense of place.
