Pon Puththagam is a simple digital notebook for goldsmiths: customers, orders, kooli, stock, dues and daily rates — designed to work without an internet connection.
No account. No ads. No real-time sync. Your book stays on your device unless you choose an encrypted Google Drive backup.
Built for the workbench
Kooli calculator
Calculate net weight, metal value, wastage and kooli using integer paise and gram-based rules.
Stock & purchases
Track gold and silver stock, purchases, order issues, reversals and metal received as payment.
Dues & monthly report
See outstanding balances, payment history and a monthly earnings summary without spreadsheets.
Encrypted backup
Export a password-protected backup file, or optionally keep an encrypted copy in your own Google Drive app data.
Works offline
Core bookkeeping works in airplane mode. Internet is only needed for optional Drive backup and subscription checks.
Your data, your choice
The app stores business records in a private local database. Manual backups are encrypted on your device with a password you choose. Optional Google Drive backup uploads only the encrypted file to your private Drive app-data folder.
There are no advertising, analytics or crash-reporting SDKs in the app. Google Play processes subscription payments; the app never receives your card details.
Closed testing
Pon Puththagam is being prepared for a small closed test with goldsmiths in Tamil Nadu. If you would like to try it and share feedback, write to us.
Please do not send real customer data in email or screenshots.
