Privacy Policy
Last updated: October 1, 2026
Short version: Weave has no backend, no account system, and no third-party analytics or advertising SDKs. Your workout data is read from Apple Health, processed entirely on your iPhone, and never transmitted anywhere by Weave.
Who this policy covers
This policy applies to the Weave iOS app ("Weave"), published by Rinnebühl Labs. It describes what data Weave accesses on your device and, more importantly, what it does not do with it.
Data Weave reads from Apple Health
With your permission, Weave reads the following workout data from HealthKit to build your share cards:
- Workout type (e.g. run, ride, walk)
- Distance, duration, and pace
- Active energy burned (calories)
- Heart rate
- Elevation gain
- Route / GPS path recorded by your Apple Watch or iPhone (
HKWorkoutRoute)
This access is read-only. Weave never writes to, modifies, or deletes anything in Apple Health. Permission is requested in stages: workout-list access when you first open the app, and route or heart-rate detail only when you open an individual workout.
Where this data goes
Your workout data stays on your device. Weave has no server, no cloud sync, and no database of any kind. All card rendering, route drawing, and workout merging happens locally on your iPhone using Apple's own frameworks (HealthKit, MapKit, Core Graphics). Rinnebühl Labs does not receive, see, or store any of your health or workout data at any point. Route cards with a map use Apple’s MapKit, which loads the map for your route’s area from Apple Maps, as any map app does.
Photo library access
When you export a card or sticker, Weave saves the resulting image to your photo library. This only happens when you explicitly tap export or save — Weave does not read your existing photos.
Analytics, advertising, and third parties
Weave does not integrate any analytics, crash reporting, advertising, or other third-party SDKs. There are no trackers of any kind in the app. No data about you or your usage is shared with, or sold to, anyone — because none is collected in the first place.
Website beta signup
You can voluntarily submit your email address through the Weave website to request an invitation to the TestFlight beta. This waitlist is separate from the Weave app: the app has no account system, login, or Sign in with Apple.
The website sends your email address to Formspree, our form-processing provider, so we can receive and manage the beta request. We do not send workout, Apple Health, or other app data through this form. If you want to be taken off the beta list, email info@rinnebuehl.de.
In-app purchases
Weave Pro is a one-time in-app purchase processed entirely by Apple through StoreKit. Rinnebühl Labs never sees your payment details — Apple handles billing and shares only the entitlement status (whether you own Weave Pro) with the app.
Location services
Weave does not request or use live device location (there is no location permission prompt). Route maps are built from the GPS path already recorded with your workout in Apple Health, not from tracking your current location.
Children's privacy
Weave is not directed at children and does not collect data from anyone, of any age.
Changes to this policy
If Weave's data practices ever change, this page will be updated and the "last updated" date above will reflect the change. We will announce significant changes on this page.
