Privacy Policy — Dukaan Khata
Last updated: 30 September 2026
What the app stores
Dukaan Khata stores the shop's ledger on the phone: customer names, phone numbers, localities, amounts given and received, notes and photos the shop adds. This data is entered by the shop and stays on the device.
Google Drive backup
If the shop signs in with its Google account, the app backs up its data to that account's Google Drive. It uses only the drive.file permission, so it can see and change only the files it created itself (the "Dukaan Khata Backup" folder). It cannot read any other file in the Drive.
Every backup is encrypted on the phone with AES-256-GCM before upload, using a recovery key that only the shop's owner holds. Google and the app's developer cannot read the backups.
What the app does not do
- No server: the app talks only to Google Sign-In and Google Drive.
- No analytics, tracking, advertising or crash-reporting services.
- No data is sold, shared with or sent to anyone else.
Messages and statements
When the shop sends a payment reminder or a statement, the app opens WhatsApp (or another app the shop picks) with the message ready. The shop decides whether to send it. That app's own privacy policy then applies.
Removing data
Uninstalling the app deletes the data on the phone. Backups can be deleted from Google Drive at any time, and the app's access can be removed at myaccount.google.com/permissions.

गोपनीयता नीति — दुकान खाता
- पूरा हिसाब (ग्राहकों के नाम, फ़ोन नंबर, उधार, जमा, फ़ोटो) दुकान के फ़ोन पर ही रहता है।
- बैकअप दुकान के अपने Google Drive में जाता है, और भेजने से पहले फ़ोन पर ही ताले में बंद (encrypted) किया जाता है। उसे सिर्फ़ मालिक की रिकवरी चाबी से खोला जा सकता है।
- ऐप Drive में सिर्फ़ अपनी बनाई फ़ाइलें देख सकता है, बाकी कुछ नहीं।
- कोई सर्वर नहीं, कोई विज्ञापन नहीं, कोई ट्रैकिंग नहीं। डेटा किसी को बेचा या भेजा नहीं जाता।
- याद दिलाने का संदेश WhatsApp में खुलता है; भेजना है या नहीं, यह दुकान तय करती है।
