You own your data.
It was always yours. loophole is how you finally read it, in plain language, right on your phone.
Now in public beta on TestFlight. iPhone, iOS 17 and later. · Privacy
The readings are yours. So is the readout.
Your ring already tracks you around the clock. loophole gives you the numbers back, in plain language, and keeps them on your phone.
Nothing leaves your phone
All your health data stays on this device. No server of ours receives it. We cannot see it.
Read straight from the ring
A direct Bluetooth link to the ring on your finger. Heart rate, HRV, temperature, SpO₂ and inter-beat intervals decode right on your phone.
Estimates say so
When loophole computes a score from your ring's signals instead of reading an official one, it labels it an estimate. Never a number dressed up as fact.
Export or delete, anytime
Take everything with you as a file, mirror it into Apple Health, or wipe it for good. Optional encrypted iCloud backup lives in your own iCloud, not ours.
Three ways in
Pick the path that fits. All of them land the same place: your data, on your phone.
Direct Bluetooth
Connect to your smart ring over Bluetooth and read it on your phone. Nothing in between.
Import your export
Drop in your ring's data-portability export. Parsed on your phone, under your own data rights.
Cloud API (optional)
Prefer live updates? Paste a personal token from the ring maker's cloud. The one path that uses their servers, and loophole says so.
Keep the maker's app too
You do not have to choose. Keep the official app for firmware updates and connect loophole over Bluetooth alongside it. Here is how.
Insights, not instructions
loophole surfaces patterns in your own numbers and, if you turn it on, reads them in plain language on your iPhone. Informational only: not medical advice, not a medical device.
