Sanctuary Browser Guard

Sanctuary Browser Guard helps you preview and protect sensitive prompts before sharing them from iPhone. Paste or type a prompt, run an on-device protection preview, and see what would be redacted before the text leaves the device. The local scanner detects common sensitive data such as email addresses, phone numbers, Social Security numbers, payment-card-like strings, and API tokens, then shows a protected version that can be copied or shared. The app opens in instant demo mode with no account required. No server setup, subscription, or credentials are needed for App Review to use the local preview flow. Sanctuary Browser Guard does not show ads and does not sell user data.
