The payslip, the receipt, the offer line, the Form 16. One encrypted place, each one tied to the number it backs.
A folder of PDFs is storage. Knowing which number a page backs is the useful part.
The reimbursement you never claimed sits in an email from fourteen months ago. The rent receipts are in a WhatsApp thread. The Form 16 is on a laptop you handed back.

Awaiting youEncrypted at rest under a per-user key. Yours to delete, permanently.
ARTH stores the link, not just the file.
Every document points at the figure it backs. Every figure points back at its document.
Capture is easy. Producing the right page, months later, in under a minute is the part that pays.
Camera, file picker, or a PDF shared from any app. It arrives because you put it there.
Sarvam handles scans, photographs and multi-language pages. A crooked photo of a stamped payslip is a normal input.
Type, period and figures - each with a confidence rating, and a list of what it could not read.
The document binds to the figure it supports. A claim later assembles itself from these links, not from your memory.
AES-256-GCM under a per-user key. Keys in Google Cloud KMS, files in the asia-south1 region.
Scoped, visible, permanent. Your tax and paycheck data goes; your login stays.
Only documents that back a number you can see. Nothing is kept because it might be useful one day.
Reading a document, understanding one, and storing one are three jobs with three different guarantees.
Sarvam AI
Document digitisation
Indian payslips arrive as scans, phone photos, and PDFs that were never meant to be read by a machine - often not in English. Sarvam's document-digitisation API turns those pages into clean structured text before anything tries to interpret them.
Runs only on a document you uploaded. Returns text, never a decision.
Google Gemini
Structured interpretation
Gemini takes that text and proposes a structure: employer, pay period, each earning and deduction line, and a confidence rating per line. It also writes down what it is unsure about, as questions for you.
Proposes. Never confirms. Every line lands in your review queue before it counts.
Google Cloud
Keys and encrypted storage
Documents live in encrypted object storage in the asia-south1 region, under per-user keys managed by Google Cloud KMS.
Encrypted at rest with AES-256-GCM. Deletable on your command.
Vendor names and logos belong to their owners and are shown here only to describe how ARTH is built. Tax figures are never produced by a language model - those come from a deterministic, versioned rule engine.
Held on purpose. Not a gap waiting for a roadmap.
Your inbox stays yours. No Gmail, no Drive, no mailbox of any kind.
Your documents stay out of every training set, and out of every other account.
Nothing sends itself. A claim pack waits for you to press send.
Delete means deleted. No quiet archive tier, and no way for us to bring it back.
