WindowGuard Support
Keep customers, projects, field measurements, product rules, quotes, and order checks together in an offline-first workflow.
Complete a project
Create a customer and project, add rooms and openings, then record the original measurements separately from any production dimensions. Before exporting an order document, resolve blocking checks and capture a current customer confirmation.
Understand safety checks
Warnings point out missing dimensions, conflicting measurements, product-rule limits, missing required photos, and other details that need review. They assist your work but do not replace professional measurement, supplier instructions, or final order verification.
Back up and restore
Open Tools → Backup & Restore to export a complete JSON backup. It can include customer details, measurements, quotes, photos, signatures, supplier rules, and company information, so store and share it securely. Restoring replaces the app's current local records after confirmation.
Restore Pro
If the App Store version offers the one-time Pro purchase, open Settings → Permanent Pro and choose Restore Purchases while signed in to the Apple Account used for purchase. Apple manages billing and refund requests.
Contact
Email appsupport.hf@gmail.com with your device model, iOS or iPadOS version, app version, and steps to reproduce. Screenshots are useful when they do not expose customer details. Do not send backups, signatures, access codes, Apple Account credentials, or payment information.
