Proof you were there. Nothing more.
Sally Forth! is a location credentialing platform. You visit real-world places and earn portable digital credentials that prove you were there — signed, verifiable, and yours to keep.
Visit a location. Tap a button. Your phone confirms your GPS is within range, and Sally Forth! issues a signed digital credential. Share it, verify it, export it — it belongs to you.
No tracking. No check-in feeds. No social graphs. Just a signed receipt that says “I was here” and the math to prove it.
Credentials are portable. Export them, share them via QR code, save them as files, or import them into other apps that support the Quest Protocol. If Sally Forth! disappeared tomorrow, your credentials would still be verifiable.
Our database doesn’t contain names, emails, phone numbers, or any personal details. Authentication is handled by a separate provider. Our system only sees random identifiers. We literally cannot look up who someone is.
Verification is public and free. No account needed. Paste a credential into the verify page and the cryptography confirms whether it’s real. No trust in us required.
Sally Forth! is the reference implementation of the Quest Protocol. Any developer can build a compatible app. Credentials issued by one app can be verified by another. Like email — many providers, one standard, no lock-in.
Sally Forth! is a progressive web app — it works in any modern browser and can be installed on your phone’s home screen like a native app. No app store required.
