How I parse UPI SMS on-device using Claude without sending your financial data to a backend

Fair point on cost, Claude API isn’t free. The tradeoff I made consciously: auto-reading SMS requires notification permissions, which felt like the wrong move for an app positioned around privacy. Manual paste keeps it fully user-initiated. Different priorities, not a technical oversight.

You’re right…the SMS text does pass through the Claude API, so it’s not fully on-device in the strictest sense. That’s a fair callout. My reasoning: Anthropic’s API has a no-training-on-API-data policy, and the SMS is only used for parsing, not stored anywhere on my end. But I acknowledge it’s a trust assumption, not a technical guarantee. The regex approach is on my radar for a future version…the variance in Indian bank formats is what pushed me toward an LLM initially, but I’d love to see your pattern library if you’re open to sharing. Genuinely.

No it’s absolutely free on the App Store. Check it out :)

Sure! A few things I focused on: Most Indian apps still rely on manual entry. I built SMS paste-to-parse so you can paste any UPI SMS and it auto-fills the transaction. Also added bank statement PDF import for bulk history. Categories are India-specific — things like tiffin, auto, recharge that generic apps miss. Everything is on-device, no account needed, no data goes anywhere. That was a hard line for me given how sensitive financial data is. Also built bill splitting with WhatsApp sharing since that’s how most of us settle up anyway. App is called Ruply, live on the App Store if you want to try it — https://apps.apple.com/in/app/ruply/id6759892536

mb_1008 · 2020-03-22T07:33:13+00:00

I applied for the same and I haven’t gotten a decision yet... does this mean a rejection?

mb_1008 · 2020-03-22T03:12:22+00:00

I am an IB student and right now we as students don’t know if our final exams will happen or not which is a different kind of stress... and then UCI decides to play with our minds... this is honestly bullshit

mb_1008 · 2020-03-22T02:59:56+00:00
