Building a loan app in India: modules, integrations, RBI rules and Play Store policy

A loan app is a borrower app, an LOS, an LMS and a stack of integrations that must satisfy the RBI and Google Play. Here's how the pieces fit and what to check.

A loan app is not one app. It is a borrower-facing mobile app sitting on top of a loan origination system, a loan management system and a dozen third-party integrations, all of which have to satisfy a regulator and an app store before a single rupee is disbursed. That is why choosing a lending app development company is less about who can design nice screens and more about who understands how the whole stack fits together.

This guide breaks down the modules you need, the integrations that take the most time, the RBI digital lending rules that shape the architecture in India, and the Google Play policy that decides whether your app goes live at all. It is practical guidance, not legal advice: your lender's compliance team and counsel have the final word.

The three systems behind every lending app

Whether you're an NBFC building your own app or a lending service provider (LSP) partnering with one, the product splits into three parts.

Many teams try to save time by building the borrower app first and "adding the back office later." In practice the LOS rules decide what the app asks for, and the LMS decides what the app shows after disbursal, so all three need to be designed together. We cover each back-office system in more detail on our loan origination system and loan management system pages.

Borrower app: the screens that decide conversion

Every extra step in onboarding costs approvals. A typical digital personal loan journey looks like this:

1. Mobile OTP login and explicit, purpose-specific consent capture (with a stored audit trail).
2. PAN and basic profile, with name matching against PAN records.
3. KYC: Aadhaar-based eKYC or DigiLocker, CKYC lookup, selfie with liveness check, or video KYC depending on the lender's policy.
4. Bank account verification through penny-drop or reverse penny-drop.
5. Income assessment: Account Aggregator consent or bank statement upload and analysis.
6. Offer screen with amount, tenure, APR and all charges, followed by the Key Fact Statement.
7. E-sign of the loan agreement and e-mandate setup through e-NACH or UPI Autopay.
8. Disbursal status, then a post-disbursal dashboard: schedule, due dates, payment links, foreclosure, statements and grievance contact.

The best lending apps show the borrower a realistic offer as early as possible and only ask for heavier documents once there is something to accept. From a growth point of view, every step should fire an analytics event, because you will want to optimize ad campaigns toward approved or disbursed loans rather than installs.

LOS and LMS: what the back office must handle

Loan origination system

• Lead and application management with stage tracking and drop-off reasons.
• A configurable business rules engine (BRE): eligibility, bureau score bands, income-to-EMI ratios, pin-code and employer rules, so the credit team can change policy without a code release.
• Bureau integration with one or more credit information companies (TransUnion CIBIL, Experian, Equifax, CRIF High Mark).
• Fraud and duplicate checks: device fingerprinting, velocity rules, dedupe on PAN, mobile and bank account.
• Manual underwriting queue with maker-checker approval and full audit logs.
• Document generation: sanction letter, Key Fact Statement and loan agreement.

Loan management system

• Loan account creation on disbursal, with schedule generation for EMI, bullet or daily-interest products.
• Interest accrual, fees, penal charges and GST handling.
• Mandate presentation and retry logic, plus payment gateway and UPI collections.
• Automated reconciliation between bank statements, gateway settlements and loan accounts.
• DPD buckets, collection queues and communication triggers (SMS, WhatsApp, IVR, email).
• Foreclosure, part-payment, closure and no-dues certificates.
• Monthly bureau reporting files and lender reporting.

Integrations that take the most time

Integrations, not screens, are what usually push a lending app timeline out. Plan for sandbox access, commercial agreements and UAT with each provider.

RBI digital lending rules that shape the build

The RBI's Digital Lending Directions, issued in May 2025, consolidated earlier circulars into one framework. In November 2025 the RBI folded its rules into consolidated, entity-wise Master Directions; for NBFCs, digital lending now sits in Chapter III of the NBFC Credit Facilities Directions, 2025. The substance carried over. For a development team, these are the points that change the architecture:

• Money flows directly. Disbursal goes into the borrower's bank account and repayment goes straight to the lender's account. No LSP pool or pass-through accounts. Your payment design must reflect this.
• Key Fact Statement before signing. The borrower sees a KFS with the all-in APR, and signed documents flow automatically to their verified email or SMS.
• Cooling-off period. Borrowers can exit within a lender-defined window (at least one day) by repaying principal and proportionate APR without penalty. The LMS needs a flow for this.
• Need-based data with explicit consent. Apps must not access files and media, contacts, call logs or telephony functions. One-time camera, microphone or location access for onboarding or KYC is allowed with consent. Borrowers can revoke consent and ask for deletion.
• Data stored in India. Borrower data must sit on servers located in India. Choose your cloud region and every third-party SDK accordingly.
• Grievance officer details must appear in the app, on the website and in the KFS.
• DLA reporting. Regulated entities report every digital lending app they use, including LSP-owned ones, on the RBI's CIMS portal, and the RBI publishes that list.
• Multi-lender LSPs must show all matching offers in an unbiased way, with lender name, amount, tenure, APR and charges.

Rules change. Before you finalize scope, have your lender's compliance team confirm the current requirements for your product type.

Google Play's personal loan app policy for India

Google Play is where most Indian borrowers will find you, and it has its own rules on top of the RBI's. Under the Play personal loan policy:

• The app must be in the Finance category, with a completed financial features declaration in Play Console.
• The listing must disclose minimum and maximum repayment period, maximum APR, a representative total-cost example and a privacy policy.
• Loans that must be repaid in full within 60 days of issuance are not allowed.
• Loan apps cannot request permissions for contacts, photos, media and storage, precise location, phone numbers or the list of installed apps.
• In India, only apps that are on the RBI's list of digital lending apps deployed by regulated entities can be submitted. Platforms that only facilitate loans must declare this and name every partner NBFC and bank prominently in the app description.

Google's India guidance set October 30, 2025 as the date from which new loan apps needed to be on the RBI list for their first release, and January 28, 2026 for existing apps to stay available. So in practice, your lender has to report the app on CIMS and it has to appear on the RBI list before you plan your Play launch date.

Questions to ask a lending app development company

• Have you built and launched a lending app that passed Play review in India? Which parts did you build?
• How do you keep LSP and lender systems separate for money flows and data access?
• Can the credit team change BRE rules without a release?
• How is consent captured, stored and revoked, and where is the audit trail?
• Which cloud region and third-party SDKs will hold borrower data, and are they all in India?
• Which analytics events will you send to ad platforms so campaigns can optimize for disbursals?
• Who owns the code, the Play Console account and the cloud accounts? (It should be you or your lender.)

Frequently asked questions

How much does it cost to develop a loan app in India?

It depends on scope. A borrower app on top of an existing LOS and LMS costs far less than building all three systems, and integrations such as KYC, bureau, Account Aggregator, e-sign and e-NACH add both development time and vendor fees. Get a fixed-price quote against a written scope that lists every module and integration rather than relying on a headline number.

Does a loan app need RBI approval?

The app itself isn't licensed, but lending must be done by an RBI-regulated entity such as a bank or NBFC. That lender must report the app on the RBI's CIMS portal, and the RBI publishes the list. Google Play only accepts Indian personal loan apps that appear on that list, so the regulated partner is essential.

What permissions are loan apps not allowed to use on Google Play?

Google Play bars personal loan apps from requesting access to contacts, photos, media and external storage, precise location, phone numbers and the list of installed apps. RBI rules separately say lending apps must not access files, media, contact lists, call logs or telephony functions, apart from one-time consented camera, microphone or location access for KYC.

What is the difference between an LOS and an LMS?

A loan origination system handles everything up to disbursal: applications, bureau pulls, credit rules, fraud checks, underwriting and sanction. A loan management system handles everything after: the loan account, repayment schedule, interest and charges, mandate presentation, reconciliation, collections, closure and bureau reporting. A lending app needs both, connected to the borrower app.

Can an LSP collect loan repayments in its own account?

No. Under RBI digital lending rules, repayments go directly from the borrower to the regulated lender's bank account, and disbursals go directly to the borrower's account. Pool or pass-through accounts controlled by an LSP aren't permitted, and the LSP's fees are paid by the lender, not charged to the borrower.

How long does it take to build a lending app?

A focused borrower app connected to an existing LOS and LMS can be built in a few months. Building all three systems takes longer, and integrations usually set the pace because each provider needs agreements, sandbox access and testing. Leave time for the lender to report the app to the RBI and for Google Play review.
