Testing whether a tool can be genuinely useful with zero access to your data.
Case study
Timer
Sessions, stored locally.
State lives in chrome.storage.sync and follows your Chrome profile. No account, no sync service, nothing to sign into.
Permissions
The manifest is the privacy policy.
The extension requests no host permissions, so Chrome will not grant it page content — even if the code asks.
No backend to breach. No dependencies to audit.
Craft
Artwork generated, not exported.
A Python tool renders the sprites. A test fails if the popup and this site drift apart.
