App release notes, technical explorations on privacy engineering, and essays on minimalist design philosophy. Written from Bristol & Bath.
Privacy isn't a feature you bolt on — it's a constraint you design around. This long-form piece walks through the architectural decisions we make on every project: data flow analysis, threat modelling, on-device processing patterns, and how to balance convenience with sovereignty. For teams who refuse to ship surveillance-default products.
