Privacy — CostWatch PoC
This Proof-of-Concept analyses your bank CSV entirely in your browser. We do not send your CSV or transaction data to any server.
Details:
- What we process: local parsing of the CSV file you select in the demo, grouping and lightweight heuristics to surface repeated payments.
- What we never collect: your raw CSV, transaction rows, account numbers, or personally identifiable information — regardless of whether you're signed in.
- Telemetry: the demo has no telemetry by default. Any analytics will be opt-in, aggregated, and non-identifying.
Optional accounts: individual mode works fully without signing in. If you choose to sign in, CostWatch automatically syncs your detected results to your account — the merchant name, how many times it charged you, the average amount, and the interval between charges — so you can see the same summary on another device. It does not sync your raw transaction rows, dates of individual charges, or the source CSV itself; those stay in that browser's local storage only. Business mode (Xero) is different: it fetches and stores your actual transaction data server-side once you connect an account, because that's what makes the automatic connector work.
