Hisaab for Android
This section covers Hisaab, our Android bookkeeping app
(app.channnuu.hisaab). The website practices described below apply
when you visit nanti.ai or contact us.
Your ledger stays on your device
Hisaab stores the books, amounts, dates, categories, payment modes, notes, and people or business details that you enter on your device. Core bookkeeping works offline and does not require a Hisaab account. The current app does not send your ledger to Nanti AI, include advertising, or use third-party analytics or crash-reporting services. We do not sell your ledger information.
App lock and backup files
The optional app lock uses Android's biometric or device screen-lock authentication. Android handles that authentication; Hisaab does not receive your fingerprint, face template, or device PIN. Recovery archives are encrypted on your device using the backup password you choose. Keep that password safe: we do not receive it and cannot recover an archive if you lose it.
You choose where to save exported reports and backup files through Android's file picker. If you choose Google Drive or another storage provider, that provider handles the file under its own terms and privacy policy. Nanti AI does not receive a copy. Reports exported as CSV, Excel, or PDF are separate from the encrypted recovery archive; protect and share them carefully. Your Android settings may also allow system backups or device-to-device transfers, which are managed by Android and your device or Google account settings.
Deleting your information
You can remove Hisaab's local data using Android's app storage settings or by uninstalling the app. Exported reports, saved recovery archives, and system backups can remain separately; delete those copies through the file manager, storage provider, or backup settings where they are stored. We do not hold a server-side copy of your ledger to delete. If you email us for support, we receive the information you choose to include; please avoid sending financial records or backup files unless needed.
Hisaab is intended for adults and is not directed to children. For privacy questions or a request about information you have sent to our support team, email hello@nanti.ai. We will update this policy before introducing changes to how the app handles data.
What the website collects
If you join the early-access list, we store the email address you give us, when you gave it, and which form on the page you used. If you write to us, through the contact form or by email, we have your name if you gave it, your email address, and what you wrote. If you subscribe to a paid plan, we keep your subscription record: the plan, the number of seats, the email on the account, and its payment status. That’s it.
What we do with it
Two emails, and no drip in between: a quick note the moment you join, so you know you’re on the list, and a heads-up when early access opens to you. Plus a reply whenever you write. When you use the contact form, we send a copy of your message to your inbox so the conversation can continue there. We don’t sell it, rent it, or share it with anyone but the email service that delivers those.
No cookies, and honest analytics
This site sets no cookies, so there is no banner. We count page views with Vercel Web Analytics, which is cookieless and anonymized: it tells us which pages get read, never who read them. No advertising trackers, no cross-site tracking, no fingerprinting, and nothing that could be tied back to you.
Payments
If you subscribe to a paid plan, payment is processed by Razorpay, our payment provider. We never see or store your full card details: Razorpay handles them under its own security and compliance. We keep only your subscription record so we can run and support your account. See our cancellation and refund policy and terms.
Where it lives
Signups are stored with the email service provider we use to manage the early-access list, and confirmations are delivered through it, from hello@nanti.ai, under their security practices and ours.
Your rights
Want out, or want your data deleted? One email: hello@nanti.ai. We’ll confirm when it’s done. Every update we send includes an unsubscribe link.
Changes
If our practices change, for example when products launch, this page changes first, with a new date at the top.
