On-device classifier
iOS hands each SMS to Relay through a Shortcut you control. The classifier runs locally. No cloud reads, no third-party processors.
No analytics, no tracking
There's no SDK collecting events. The only network call Relay makes is the one delivering your message to the destination you picked.
Optional Telegram bot
Use the hosted bot for 15-second setup, or paste credentials for one you control. Either way, your messages don't sit on Relay's servers.
That's it. We don't have anything else to track.

Does Relay actually read my texts in the background?
No. iOS doesn't allow any app to read SMS in the background. Relay receives a message only when Apple's Shortcuts app hands one to it via a Personal Automation you set up during onboarding.
Do you collect analytics or sell data?
No analytics, no tracking, no ad SDKs, no data sales. Ever. We're a paid app, you're not the product.
Why does Relay need an Apple Shortcut? That seems clunky.
It's the only Apple-permitted way for an iOS app to learn that a new SMS arrived. Once set up (60 seconds), it runs invisibly forever.
Why is my forwarded message delayed?
iOS gives Shortcut automations a ~30-second background window. Most forwards arrive in 1–3 seconds. Delays usually mean the destination service (Telegram, your email server, etc.) is slow. Relay surfaces failures in the Activity screen.
Does Relay work on iPad?
It runs on iPad, but iPad doesn't receive SMS unless your iPhone is paired and “Text Message Forwarding” is on in iOS Settings.
Is this open source?
Not at launch. We're keeping the option open for the iOS app once we're past v1.0.
