Privacy Policy
Version 2.0 · Last updated: 21 May 2026
This policy is designed to comply with the Information Technology Act, 2000, the SPDI Rules, 2011, and the Digital Personal Data Protection Act, 2023 (India).
1. Introduction
Tax One Advisory (OPC) Pvt. Ltd. ("we", "us", "our") operates Your AI Accountant ("the Service"). This Privacy Policy explains how we collect, use, store, and protect your personal and financial information when you use the Service.
Tax One Advisory (OPC) Pvt. Ltd. acts as the "Data Fiduciary" under the Digital Personal Data Protection Act, 2023 ("DPDPA") for personal data processed through the Service. We process such data in accordance with the Information Technology Act, 2000 and the Information Technology (Reasonable Security Practices and Procedures and Sensitive Personal Data or Information) Rules, 2011 ("SPDI Rules").
2. Definitions
- Personal Data: Any data about an individual who is identifiable by or in relation to such data.
- Sensitive Personal Data (SPDI): Financial information such as bank account details, statements, and related records, as defined under the SPDI Rules.
- Data Fiduciary:The entity that determines the purpose and means of processing personal data — i.e., us.
- Subprocessor: A third-party service provider engaged by us to process data on our behalf.
- Client Data: Financial or personal data of third parties (e.g., your clients) that you upload to the Service.
3. Data We Collect
3.1 Account Information
- Full name, email address, and phone number (optional) provided during registration.
- Google account information if you sign up via Google OAuth.
- Hashed password — plaintext passwords are not stored.
3.2 Financial Data
- Bank statements (PDF, Excel, CSV) you upload for processing.
- Transaction details extracted from uploaded statements.
- Ledger names, voucher details, and categorization data.
- GSTIN, PAN, and other tax identifiers associated with your clients.
- Tally company data pulled via the Bridge agent (at your request).
3.3 Usage Data

4. How We Use Your Data
- Service Delivery: Processing bank statements, converting uploaded PDF invoices into structured data, and Tally synchronization.

- Security: Detecting unauthorized access, fraud prevention, and abuse monitoring.
- Communication: Sending password reset emails, verification emails, and critical service updates.
- Improvement: Improving extraction and matching accuracy based on aggregated and anonymized patterns.
5. AI Processing & Automation
AI is used in a single, specific part of the Service: Invoice Conversion— converting uploaded PDF invoices into structured transaction data. Bank statement extraction and ledger categorization are performed by deterministic (non-AI) processing.
- For Invoice Conversion, the relevant content of the uploaded invoice (such as invoice text, amounts, party names, and line items) may be sent to our AI provider to extract structured fields. Passwords and login credentials are not sent.
- We use API-based AI services (currently OpenAI) where customer API data is not used to train the provider's models.
- Automated processing: Invoice fields extracted by AI are suggestions only. You should review extracted data before relying on it.
- Accuracy limitation: AI-generated outputs may contain inaccuracies and should be independently reviewed by a qualified professional before filing, reporting, or financial reliance.
6. Legal Basis for Processing
We process your personal data on one or more of the following lawful bases:
- Consent: Consent you provide when you create an account and upload data.
- Performance of contract: Processing necessary to deliver the Service you have subscribed to.
- Legal obligation: Compliance with applicable Indian law, including tax and record-keeping requirements.
- Legitimate interests: Fraud prevention, security, and abuse monitoring, balanced against your rights.
7. Data Sharing & Subprocessors
We do not sell your personal or financial data. We engage the following subprocessors:
| Provider | Purpose |
|---|---|
| OpenAI | Invoice Conversion (PDF invoice data extraction) |
| Google Cloud Platform | Hosting and file storage (Mumbai region) |
| Supabase | Managed PostgreSQL database infrastructure |

These providers process data under contractual confidentiality and security obligations. We may also share data with:
- Team Members: If you use team features, your admin and staff members can access shared client data as configured.
- Client Portal: If you create client portal access, the designated client can view their own transaction data.
- Legal Requirements: We may disclose data if required by Indian law, court order, or government authority.
8. Security Measures
Under the SPDI Rules, financial information is classified as Sensitive Personal Data. We apply commercially reasonable safeguards, including:
- AES-256 encryption at rest and TLS 1.2+ encryption in transit.
- Passwords hashed using bcrypt with salt.
- TOTP-based two-factor authentication (2FA) available for accounts.
- Role-based access control (RBAC) and the principle of least privilege.
- Audit logging of sensitive operations.
- Encrypted backups and secure secret management.
- Periodic access reviews of authorized personnel.
- The desktop Bridge agent stores its authentication token locally using AES-256-GCM encryption with a machine-specific key; Tally data remains on your local network.
9. International Transfers
Your account and financial data are stored on Google Cloud Platform servers in the Asia South 1 (Mumbai) region. The only operation that may involve transmission of data outside India is Invoice Conversion, where invoice content is securely sent to our AI provider for extraction, subject to contractual safeguards and applicable law. Stored financial records and files are not transferred outside India for storage.
