PureHub beta.18: encrypted backups and local receipt OCR

PureHub is a free, no-ads, open-source collection of 22 everyday utility tools. Beta.18 focuses on making the finance and personal-data workflows more useful without sending private content to a server.

What changed

• Encrypted backup and restore: Zen Habit and Expense Tracker can export password-protected .purehub backups and restore them later.
• Receipt OCR: Expense Tracker and Bill Splitter can read a receipt locally, suggest merchant, total, tax, and line items, then ask the user to review the result.
• Document workflow: QR Studio, OCR Studio, and Doc to PDF now form a clearer path from capture to searchable PDF.
• Android choices: the release includes signed Standard APKs and a fully FOSS flavor using ZXing and Tesseract without ML Kit, Play Services, Firebase, ads, analytics, or trackers.
• Cross-platform parity: the same core finance backup and receipt workflow is available in the PWA.

Why local processing matters

Receipts, habits, and expense history can contain sensitive information. PureHub keeps OCR and backup preparation on the device. The encrypted export uses AES-GCM with a password-derived key, while imported data is validated before merging.
