Android · On-device · Free forever
Alkemi captures every transaction from your bank SMS and notifications — parsed locally, stored on device, never uploaded.
The status quo
They upload your statements to the cloud, sync your data to third-party servers, and build a profile of your financial behaviour. You don't know where it goes or who sees it.
Transaction history synced to remote servers you don't control.
Behavioural tracking and ad profiling baked into "free" finance apps.
No automatic capture from SMS or push notifications — you do all the work.
Core functionality withheld until you subscribe — or the app shuts down.
How it works
From the moment a transaction happens to the insight it produces — everything runs on your phone.
Alkemi reads your bank SMS and listens to push notifications from trusted apps — Google Pay, PhonePe, Paytm, and your bank's own app. Transactions are parsed locally using pattern matching across 50+ Indian bank formats. No text ever leaves the device.
Every transaction is categorised, deduplicated, and assigned to the right account. Budgets, weekly charts, category breakdowns, subscription detection, and spending insights surface automatically — all computed in-memory on your phone.
Your data lives in an on-device SQLite database. When you back up, the file is encrypted with XChaCha20-Poly1305 + Argon2id before it's shared anywhere — you choose where it goes. Restore needs your password and nothing else.
Privacy by design
Privacy-first isn't a marketing claim — it's a constraint built into the architecture. These aren't policies that could change. They're properties of the code.
Every transaction, account balance, goal, and debt entry is stored in a local SQLite database — alkemi.db — that never touches a network.
When you export a backup, the file is encrypted using XChaCha20-Poly1305 with a key derived by Argon2id (64 MB memory, random 16-byte salt) before your native share sheet opens.
Set a PIN or biometric lock per profile. Privacy Mode masks every balance and amount across all screens — useful on a commute or when sharing your screen.
The Android manifest does not include INTERNET in the app's own permission set. No HTTP calls, no analytics SDKs, no telemetry anywhere in the codebase.
The app
A calm, focused interface that shows you what matters — built around the way money actually moves in India.

src/theme/variants/The difference
Most finance apps are optimised for engagement and data collection. Alkemi is optimised for one thing: your privacy and accurate control over your finances.
Common questions
Yes — and intentionally so. Android's SMS broadcast system and NotificationListenerService give apps genuine, real-time access to transaction data without manual input. iOS doesn't expose these APIs. Alkemi is built around Android's native architecture, not retrofitted on top of it.
Yes, entirely. Every feature — goals, debt tracking, analytics, encrypted backups, all 8 themes — is available to every user. There are no tiers, no limits, no "Pro" unlock. The business model isn't to monetise your data; it's to build something people love and support optionally.
Export an encrypted backup (.alkemi file) at any time and store it wherever you choose — Google Drive, a USB drive, your laptop. When you get a new phone, restore with your password. No account, no server, no waiting. The backup is yours.
READ_SMS lets Alkemi scan your existing inbox for historical transactions. RECEIVE_SMS handles real-time parsing when a new message arrives. The app reads the text on-device, extracts amount, merchant, and account, then discards the raw text. The Android manifest doesn't include an INTERNET permission, so transmission is architecturally impossible.
