Frequently asked questions

It's a khata for any business that bills the same customers again and again — gyms, tuition and coaching classes, tiffin and dabba services, salons, magazine and milk rounds, and more. You track members, their subscription plans, the installments that come due, and the payments you collect.

No. You set up your shop with your name and mobile number, and start adding members. There is no account on our servers — everything lives on your phone. You only sign in to Google (optional) if you want Drive backup.

It runs on Android. The app is available in 13 languages: English, Hindi, Bengali, Marathi, Telugu, Tamil, Gujarati, Kannada, Malayalam, Punjabi, Odia, Assamese and Urdu.

Subscription Book is free to start. Any paid options will be shown clearly inside the app before you choose them.

Yes. Create as many plans as you like — weekly, monthly, yearly, or a custom number of days. When you put a member on a plan, the whole installment schedule is generated automatically.

Yes. You can add a member on their own and put them on a plan later. The default when adding a member is "No plan".

Yes. Record any amount as a payment against a member's running balance, and edit an individual installment's amount — or make it free — when you need to.

The member stays on your list as inactive, with their full history intact, and you can renew them onto a new plan at any time. Any amount still owed can still be collected after a term ends.

Tap "Send reminder" on a member who owes, choose WhatsApp or SMS, and your messaging app opens with the amount and a short message already filled in. You review it and send — it goes from your own number.

No. Nothing is sent without you tapping send in your own messaging app. We never send anything on your behalf and never see the message.

In Settings, sign in with Google to turn on Drive backup. A copy of your data is saved to a private, app-only folder in your own Google Drive. You can also export a full copy of your data at any time.

Yes. Sign in to the same Google account on both. When each phone backs up and restores, the app merges the two ledgers instead of overwriting — for any record edited in both places, it keeps the more recent version.

If you had Drive backup on, install the app on the new phone, sign in with the same Google account, and your data restores. If you never turned on backup or export, the data was only on the lost device and cannot be recovered — we never held a copy. We strongly recommend turning on backup.

No. Your data is stored on your device and, if you enable backup, in your own Google Drive. We run no server that holds it and never receive a copy, so we cannot see it — and cannot hand it to anyone else either.

Only to let you pick a customer from your phonebook, and optionally to show the phonebook name for a saved number. Contact matching is off until you turn it on, happens entirely on your device, and is never uploaded or included in a backup.

No ads, no analytics, no crash-tracking or advertising SDKs, no location, no device tracking. Read the full privacy policy for the details.

Delete any record inside the app, or remove everything by uninstalling the app and deleting the backup file from your Google Drive. Since we hold no copy, that removes it entirely.
