A sub-processor is a third-party service Altx engages to process personal data on our behalf as we deliver Notifyce. Every sub-processor with access to your personal data operates under our master Data Processing Agreement (ACPL/DPDPA/R601) in addition to its own DPA where applicable. This page is the source of truth for the current list and is updated whenever we engage a new sub-processor.

The full Record of Processing Activities (RoPA) that maps each sub-processor to the specific activities it serves is maintained internally and made available to regulators and to enterprise customers under NDA.

5. Legal & Regulatory Authorities

Where required by law — court orders, lawful statutory requests, regulator inquiries — we may disclose personal data to Indian authorities (Income Tax Department, GSTN / tax authorities, CERT-In, Data Protection Board of India, police and courts). These disclosures are not made on our instructions; they are mandated by law. We log every such disclosure for audit purposes.

6. Cross-Border Processing

All primary processing of personal data and end-client tax records is hosted in AWS region ap-south-1 (Mumbai, India). The AI providers (Anthropic, OpenAI, Google Gemini) and Google Workspace process limited data outside India under their own Data Processing Agreements. We monitor restricted-country notifications issued by the Data Protection Board of India under Section 16 of the DPDPA and will update this page on any change.

7. Notification of Changes

When we engage a new sub-processor that handles personal data, we update this page before the new sub-processor begins processing. For material changes that introduce a new purpose, a new sensitive data category, or a new cross-border transfer, we will notify our customers by email at least 30 days in advance and, where required by law, obtain fresh consent before the change takes effect.
