Problem

Cross-platform price changes are hard to track over time, and users should not have to send their shopping lists to a cloud service.

Decisions

Use the Python standard library, a local web console, and SQLite, with explicit degradation for unreliable platform sources.

Outcome

The local project supports adding products, setting target prices, running checks, and reviewing price history and events.

Reflection

Even a small utility can make privacy, truthful data, and portability product defaults.
