Subprocessors
The third parties that process customer personal data on PRACHSO's behalf, what each does and where, and how we announce changes.
What this list is
A subprocessor is a company that processes Customer Personal Data on PRACHSO's behalf to deliver the service. Each is bound by written data protection terms no less protective than our Data processing agreement.
Current subprocessors
| Function | Provider | Data processed | Location |
|---|---|---|---|
| Cloud hosting and storage | Cloud infrastructure provider, India region | All customer data: registry records, documents, challans, users | India |
| WhatsApp message delivery | Meta Platforms (WhatsApp Business Platform), through a WhatsApp Business Solution Provider | Recipient mobile number, name, language, reminder text | India and Meta's global delivery network |
| Transactional email | Email delivery provider | Recipient email address and message content | India or as stated in the provider's terms |
| Payments | Payment gateway authorised by the Reserve Bank of India | Billing contact, invoice amount, payment reference | India |
The provider names for hosting, email and payments are given on request to customers and prospective customers at security@prachso.xyz, and are published on this page as each contract is signed.
Data sources are not subprocessors
ULIP, the Parivahan, VAHAN and SARATHI services, DigiLocker and the Parivahan e-Challan system are sources PRACHSO reads from through authorised access. They do not process customer data for us, so they are not listed above. PRACHSO is not any of these services.
Changes
We email account owners at least 30 days before a new subprocessor starts processing Customer Personal Data, and update the date at the top of this page. A customer may object as described in the Data processing agreement.
