Privacy Policy
Material Guardian, published by Welders Helper, is an offline-first receiving inspection app for shop and field receiving workflows.
In the current release, jobs, receiving reports, photos, scans, signatures, and exported packet files stay on your device unless you intentionally export or share them. Backend services manage account access, organization membership, seats, and store-backed subscription status.

What stays on your device
Job content, draft reports, photos, scans, signatures, and exported packets are stored locally on your device in the current release. Cross-device cloud file sync and cloud file recovery are planned for a later opt-in upgrade and are not part of the current release behavior.
Account and backend data
If you sign in, Material Guardian may store backend account and access data needed to operate the service, including:
- your email address and sign-in session state
- email-code authentication challenges and session tokens
- organization membership, seat assignment, and workspace role state
- subscription and entitlement state linked to the app store when store-backed access is active
Camera, scanning, and exports
The app may request camera or document-scanning access only when you choose to capture material photos or scan MTR/CoC documents. Exported files are written to app storage and may also be written to a device-accessible folder such as Downloads/MaterialGuardian when you export packets.
Sharing
Material Guardian does not automatically publish your reports or media. Files are shared only when you explicitly choose an export or system share destination.
Third-party services
The Material Guardian app does not use third-party analytics or ad tracking in the current release. Public marketing pages for Material Guardian may use Google Ads measurement tags to understand campaign visits and ad performance. The service may rely on third-party infrastructure for account and billing operations, such as:
- the app store for store-backed subscriptions
- a configured email delivery provider for sign-in codes, support messages, or workspace invite emails
- backend hosting and database infrastructure used to run account, entitlement, and organization features
Security
We use reasonable administrative and technical safeguards for backend-managed account systems, including HTTPS or TLS for data in transit and access controls for service operations.
Files that stay only on your device are also subject to your device's own security settings and protections.
Account deletion and retention
If account deletion is available in your release channel, use the in-app delete-account flow to remove the backend login tied to your email. Store subscriptions may still need to be canceled separately in the app store that processed the subscription.
Business workspace records can require additional retention or ownership handling before deletion is allowed. Backend account records may be retained for a limited period where needed for security, fraud prevention, legal compliance, billing, or workspace ownership resolution. For public deletion guidance, use the account deletion page.
