Who we are
Signals is made by Ortech. This policy covers the Signals iPhone app and this website. Questions: hello@ortechhq.com.
What the app handles
- Band data. Heart rate, heart rate variability, skin temperature, blood oxygen, respiratory rate, motion and sleep, read from your band over Bluetooth.
- What Signals works out. Recovery, strain, sleep, stress, workouts and trends, calculated on your iPhone.
- Profile. Details you enter, such as age, height, weight and sex, used only to make calculations accurate.
- Journal. Notes and tags you add.
All of this is stored in the app's private storage on your iPhone. Ortech runs no servers for Signals and never receives any of it.
iCloud backup and sync
If you turn it on, Signals backs up and syncs through Apple's CloudKit, in the private database of your own Apple Account. It is protected by your Apple Account and Apple's privacy policy. Ortech cannot access it. Turn it off in Signals settings, and delete stored data in iOS Settings → your name → iCloud → Storage.
Groups
You can share your data with people you choose by giving them a QR invite. Sharing uses CloudKit sharing between Apple Accounts. Members see what you share until you remove them or leave the group. Nothing is shared unless you start it.
Apple Health
With your permission, Signals reads from and writes to Apple Health, only the types you allow. Health data is never used for advertising, never sold, and never sent to Ortech. Change access anytime in the Health app.
Permissions
- Bluetooth to connect to your band.
- Location, optional, for local weather context. Signals requests weather from Apple's WeatherKit; Apple receives your approximate location to answer. Signals doesn't store your location history.
- Camera to scan group invite codes. Images are not stored.
- Notifications, optional, generated on your iPhone.
Coach
The coach runs on Apple's on-device foundation model. Your questions and data stay on your iPhone.
What we don't do
- No accounts or sign-in.
- No analytics, tracking, fingerprinting or advertising identifiers.
- No third-party SDKs.
- No selling or sharing of data, ever.
If you choose to share crash reports or TestFlight feedback with developers in iOS, Apple passes them to us without your identity. You control this in iOS Settings → Privacy & Security → Analytics & Improvements.
This website
No cookies, no scripts, no analytics. It is served by Cloudflare, which processes standard request data such as IP addresses to deliver and protect the site.
Deleting your data
Delete the app to remove everything on your iPhone. Delete Signals data in iCloud from iOS Settings → your name → iCloud → Storage. Data written to Apple Health stays in Health until you delete it there.
Children
Signals is not directed at children under 13.
Not medical advice
Signals is not a medical device and does not diagnose or treat any condition.
Changes
If this policy changes, we'll update this page and the date above. Material changes will also be noted in the app.
