ganna.lk is private by design. Invoices, client details, calculator inputs, and homepage preferences you create are stored only on this device in your own browser (localStorage). They are never sent to, stored on, or visible to our servers.
Because your saved drafts live only in this browser, clearing your browser data or switching devices removes them — we cannot recover them from our side. Use the Backup JSON or PDF download buttons on tools whenever you want a permanent copy.
We count anonymous usage with our own lightweight analytics (no cookies, no personal identifiers), to know which tools to improve. We do not collect names, phone numbers, business data, or IP-based profiles.
In the costing calculator, anonymized material prices (item name, unit and price only) may be used for general market analysis. They are never linked to you or your business.
Shared links (e.g. Transfer-to-PC) encode your data in the URL fragment, which browsers never send to any server.
When you share via WhatsApp or email, the message travels directly through those services. We never see, store, or forward what you send.
