THE APPROACHBuild. Test. Refine.
01 / THE CHALLENGE
A clear job to do.
Make it easy to remember a purchase and decide whether it is worth trying again. The focus is a personal collection, with prices, ratings, notes, and favorites instead of a stock-management workflow.
02 / THE APPROACH
Make the useful part easy.
The local edition brings the collection, purchase details, and personal experience into one responsive interface. IndexedDB stores records and photos in the current browser, and a service worker makes the app available offline after setup.
03 / DECISIONS THAT MATTER
The details are the work.
01
Keep the collection personal
Tried, untried, finished, and favorite views help a person browse their own history. A purchase can keep its original quantity and price without requiring a running stock count.
02
Make data portable
JSON export and restore give the owner a way to move their collection. Backup validation happens before records are replaced.
03
Explain local storage honestly
The interface explains browser storage, offline setup, and the need for backups. There is no automatic cloud recovery, and exports are not encrypted.
04 / VERIFICATION
More than a screenshot.
Collection editing, purchase prices, ratings, and favorites checked in the local edition
Backup validation and restore covered by the collection tests
Offline loading and responsive layouts checked in Chrome
05 / BOUNDARIES
What this version does.
Records belong to one browser and device. Clearing site data or losing the device can remove them. Export a backup regularly. This edition does not provide accounts, cloud sync, or an access lock for a shared device.
