Your slope measurements, sensor samples, calibration, and putting data stay on your device. If you use PuttLevel Pro, Apple and RevenueCat process purchase information so the App can verify your access.
This Privacy Policy explains how PuttLevel ("the App", "we", "us", or "our") handles information. It applies to the App and its one-time PuttLevel Pro purchase.
The following data is processed and stored locally by the App:
We do not upload slope measurements, raw sensor samples, calibration values, putting history, or location data to our servers. The App does not require an account and does not include advertising or a general-purpose usage analytics SDK.
PuttLevel Pro is a one-time in-app purchase. Apple processes the payment through the App Store. RevenueCat helps the App validate the transaction, prevent purchase fraud, restore purchases, and determine whether Pro access is active.
For those purposes, RevenueCat may receive and retain:
The current App does not create user accounts, send RevenueCat a custom user ID, or set contact-information attributes. We do not receive your payment-card information, billing details, or Apple ID.
| Capability | Purpose | Processing |
|---|---|---|
| Accelerometer | Derive cross-slope, along-slope, total slope, and downhill direction for putting practice | On device |
Accelerometer samples are processed in real time on the device. PuttLevel does not send raw sensor data to Apple, RevenueCat, or the developer.
| Service | Purpose | Relevant Data |
|---|---|---|
| Apple StoreKit | Payment and purchase processing | Purchase and payment information handled under Apple's policies |
| RevenueCat | Receipt validation, entitlements, restoration, fraud prevention, and purchase analytics | Anonymous App User ID, purchase history, receipt, entitlement, and limited technical information |
| iOS motion sensors | Slope estimation | Sensor samples processed locally only |
See Apple's Privacy Policy and RevenueCat's Privacy Policy for their practices.
PuttLevel does not show ads and does not use purchase or sensor data to track you across apps or websites for advertising. We have not enabled RevenueCat integrations that use advertising identifiers. If our practices change, we will update this policy and the App Store privacy information.
PuttLevel does not require an account and is not designed to request names, email addresses, or other contact information from children. Purchase processing is still handled by Apple and RevenueCat as described above. If you believe a child has provided information to us directly, contact us so we can investigate the request.
Removing the App does not erase transaction records retained by Apple or RevenueCat.
Sensor and putting data remain on your device. Purchase information may be processed by Apple and RevenueCat in countries where they or their service providers operate, subject to their privacy policies and safeguards.
We may update this policy as the App or its service providers change. We will update the date above and publish the revised policy at this URL. Material changes may also be communicated in the App or release notes when appropriate.
