This Privacy Policy describes how Ledgester, a reference tool from Profinss ("we", "us", "our") collects, uses, and protects information when you use our website at gst-pro-toolkit.web.app and the Ledgester web and mobile application (collectively, the "Service").
1. Information we collect
We collect only what is needed to operate the Service:
Account information — when you sign in with Google, your email address, display name, profile photo URL, and a unique user ID provided by Firebase Authentication.
Business data you enter — invoices, quotations, customer / seller details, GSTINs, line items, reminders. This data is stored locally on your device and, if you sign in, synced to your private Firestore document under your user ID.
Usage analytics — anonymous events such as pages viewed, tools used, and document creation counts, collected via Google Analytics 4 and Firebase Analytics. We do not collect the contents of your invoices.
Device and log data — browser type, OS, IP address (transient, used only for security and basic geo-aggregation), and crash diagnostics.
2. How we use your information
To provide the Service — invoice creation, document storage, cloud sync, reminders.
To authenticate you and keep your data private to your account.
To improve the product based on aggregated usage trends.
Your data is stored on Google Firebase (Firestore + Cloud Storage), with industry-standard encryption in transit (TLS 1.2+) and at rest. Access to your synced data is restricted by Firestore security rules that allow only the signed-in user's UID to read or write their own documents.
4. Data we do not collect
We do not sell your data to third parties.
We do not use your invoice content for advertising or training models.
We do not share your data with any party other than the infrastructure providers below.

6. Cookies
We use cookies / local storage only for: keeping you signed in, remembering your dark-mode preference, caching draft invoices, and Google Analytics. We do not use advertising cookies.
7. Children
