Build a guided cleanup product that groups duplicate media, downloads, temporary files, oversized items, duplicate contacts, and supported email attachments into reviewable actions. It should estimate recoverable space, explain the consequence of each action, require confirmation for personal content, and verify the storage recovered. Start with Android, where local file access supports a more useful first product, then add optional cloud and email cleanup connectors.

The signals span multiple products and years, indicating a persistent workflow rather than one application's temporary defect. Growing photo, video, download, and email archives continue to create storage pressure, while inconsistent cleaner performance leaves room for a more trustworthy product.
