Din Sutra Privacy Policy

Last updated: 28 September 2026 · dinsutra.app

Summary

Din Sutra is a personal planner for tasks, habits, money, bills and udhaar. Your data stays on your phone unless you sign in to back it up. We do not show ads, we do not sell or share your data, and we do not use third-party analytics or tracking. The app sends one small anonymous count a day, which you can switch off.

Data kept on your phone

Your tasks, habits, expenses, bills, budgets, udhaar entries (the names, amounts and any phone numbers you type in) and settings are saved in the app's private storage on your phone. Uninstalling the app removes them. The app does not read your contacts, messages or bank SMS.

Shop khata (optional)

If you turn on the shop khata, the app also keeps your shop's name, UPI ID and number, the customers and suppliers you add (their names and any mobile numbers you type in or pick from your contacts), their khata entries and your cash book. Picking a contact opens your phone's own contact picker: the app gets only the one contact you choose and never reads your address book. Bill photos you attach stay only on this phone, in the app's private storage, and are never uploaded or backed up. PDF statements and spreadsheets are made on your phone and go only to the app you share them with. Please add only people who expect you to keep their account.

App lock

App lock asks for your phone's own screen lock (fingerprint, face, PIN or pattern). The check happens in your phone; the app never sees or stores your fingerprint or PIN.

Account and backup (optional)

If you sign in, we store your email address or mobile number (the one you signed in with) and a copy of your Din Sutra data, including udhaar entries and the shop khata (but not bill photos), so it can be backed up and kept in step across your phones. This is hosted by Supabase on servers in Mumbai, India, and protected so that only your account can read it. Sign-in codes are sent to your email by our email provider, Resend, or to your mobile number by SMS through our SMS provider. If you sign in with Google, Google tells us only your name, email address and profile picture; we use the email address for your account and do not get access to anything else in your Google account.

Backup file (optional)

Settings can save all your Din Sutra data (not bill photos) as one file, made on your phone. It goes only where you share it, such as your Google Drive or a chat with yourself, and anyone with the file can read it, so keep it somewhere private. Restoring a file adds its data to the app on your phone.

Microphone and voice

Voice input uses the microphone only while you are speaking to the app after tapping the mic. Your phone's speech recognition service (for example Google) turns the speech into text, under that service's own policy. Din Sutra does not record or keep audio; it only uses the text.

Paying bills with UPI

To pay a bill, the app checks which UPI apps are installed on your phone so it can offer them, and opens the one you pick with the bill's details. This list never leaves your phone. The payment happens inside that UPI app; we never see your card, UPI PIN or bank details.

WhatsApp reminders and sharing

When you remind someone about udhaar on WhatsApp, or share a card, the app hands the message or picture to the app you choose. Nothing is sent by us.

Anonymous daily count

Once a day, when you open the app, it sends a random install ID made by the app (not linked to your phone, your name or your account), the date, the app version, the platform, the app language and whether you are signed in. This only tells us how many people use Din Sutra each day. It never includes your tasks, habits, money or udhaar. Switch it off in Settings > Share an anonymous usage count. These rows are kept for up to 13 months.

App settings from our server

When it opens, the app downloads a small settings file from our server: whether an update is needed, a short announcement, and which features are on. No personal data is sent to fetch it. Like any website, our hosting provider may keep standard server logs, such as IP addresses, for a short time for security.

Feedback

If you send feedback from the app, we receive your message, the contact detail you choose to add, the app version, platform and language, and your account id if you are signed in. We use it only to reply and to improve the app.

Your course website (optional)

If you connect your course website with a code from its dashboard, the app receives from that website your course names, reading progress, mock test scores and ranks, achievements and a masked email address, and keeps a copy on your phone so it also shows offline. The app can only read these; it cannot buy, change or download anything on the website, and it never sends your Din Sutra data there. Disconnect it at any time in Settings, or remove the app on the website's dashboard.

Crash reports

If the app crashes, it sends the error message, technical details of where it happened, the app version and the phone platform, so we can fix it. Crash reports do not contain your tasks, habits or spending. If you are signed in, a report is linked to your account id.

Notifications, festivals and widget

Reminders, festival and vrat dates are worked out and scheduled on your phone, and the home-screen widget reads data saved on your phone. None of them sends data anywhere.

AI features

When AI features are available and switched on in Settings, the text needed for a request (such as a Quick Capture line, or a summary of today's tasks, habits and spending for the Morning Brief) is sent through our server to Anthropic, which provides the AI model. It is used only to answer that request. You can switch AI off at any time; the app then works fully offline.

Purchases

Din Sutra is free today. If paid features are added later, they will be bought through Google Play. Google handles the payment; the app only learns from Google Play whether you have an active subscription.

Deleting your data

Settings > Account & sync > Delete account permanently removes your account and your backed-up data. You can also email us to ask for deletion, including feedback you sent. Data on your phone is removed when you uninstall the app. Crash reports are kept for up to 90 days.

Children

Din Sutra is not directed at children under 13 and we do not knowingly collect their data.

Changes and contact

If this policy changes, we will update it here and in the app with a new date. Questions or requests: dinsutra.app@gmail.com.
