Subprocessors & Data Infrastructure

Last updated: 12 October 2026
1. Introduction
Vistra uses selected third-party service providers (“Subprocessors”) to help deliver, maintain, secure, and improve the Vistra platform.
These providers may process customer information only when necessary to provide specific services.
This document explains:
- What subprocessors are
- Why Vistra uses them
- The categories of information they may process
- How Vistra manages third-party service providers
2. What is a subprocessor?
A subprocessor is a third-party company engaged by Vistra that may process customer information while helping provide the Services.
Examples include providers supporting:
- Cloud infrastructure
- Data storage
- Payments
- Email delivery
- Push notifications
- Crash reporting
- Artificial intelligence features
Vistra remains responsible for ensuring subprocessors are subject to appropriate contractual and security obligations.
3. Subprocessor management
Before using third-party providers, Vistra considers factors including:
- Security practices
- Privacy protections
- Reliability
- Data handling procedures
- Service requirements
Subprocessors are only granted access to information necessary for their specific function.
4. Current subprocessors
These are the providers we use today. We do not use any analytics or advertising provider.
4.1 Hosting and file storage
Provider: Amazon Web Services.
Purpose: to host and operate Vistra, store the database and uploaded files, and hold database backups.
Information processed may include account information, uploaded content, reports and technical information.
4.2 Payment processing
Providers: Stripe (United States and Ireland) for web payments. Apple and Google process payments for subscriptions bought in the mobile apps. RevenueCat (United States) keeps track of in-app subscriptions.
Purpose: to process subscription payments and manage in-app subscriptions.
These providers process billing information, transaction details and subscription status. Vistra does not store complete payment card numbers. Tax invoices and payment records are held in their systems.
4.3 Push notifications and crash reporting
Provider: Google Firebase (United States). Apple’s notification service delivers push notifications to iPhones and iPads.
Purpose: to deliver push notifications and, only if you agree in the app, to receive crash and performance reports.
Information processed includes a device notification token, and device and app details and technical error information if you have agreed to diagnostics. It does not include report content or photos.
4.4 Artificial intelligence providers
Providers: Anthropic and OpenAI (United States), used only when someone uses an optional AI feature.
Purpose: to provide AI-assisted features such as suggested descriptions and report wording.
Information processed is the content submitted through the AI feature, which may include inspection notes, prompts and photos. A person reviews all AI output before it is used.
See our AI Usage Policy for more.
4.5 Email delivery
Provider: Microsoft 365 (Microsoft), in Australia and the United States.
Purpose: to send service emails such as account, sharing and billing messages, and marketing emails to people who have opted in.
Information processed includes email addresses and the content of the messages.
4.6 Error monitoring
Provider: Sentry (Functional Software, Inc., United States).
Purpose: to detect and fix errors in the Vistra servers.
Information processed is technical error information, such as the page or API address that failed and the error details, and it may include an IP address. We configure it not to send request bodies, cookies, login credentials, the values held in our code when an error happens, email addresses, or the secret parts of share and email links, and we configure it to avoid sending report content or photos.
5. Data location
Customer information may be processed and stored in locations where Vistra and its service providers operate.
The location of stored data depends on:
- Infrastructure configuration
- Service provider availability
- Applicable agreements
Where required, Vistra applies appropriate safeguards for international data transfers.
6. Customer data protection
Vistra requires subprocessors to maintain appropriate protections regarding customer information. These protections may include:
- Confidentiality obligations
- Access restrictions
- Security controls
- Privacy commitments
- Contractual requirements
7. Customer responsibilities
Customers are responsible for:
- Understanding their own compliance obligations
- Configuring user permissions
- Selecting appropriate information to upload
- Ensuring lawful collection of customer data
Vistra provides tools to help manage information but does not determine customer compliance requirements.
8. Changes to subprocessors
As Vistra grows, we may add or replace subprocessors to:
- Improve reliability
- Improve security
- Add functionality
- Support new features
Material changes may be communicated through:
- Website updates

9. Customer objection rights
Where required by applicable agreements or laws, customers may have the right to object to the appointment of certain subprocessors.
