I'm George Yameen, the creator of TennisWatch. I built this app because I love tennis and wanted a better way to track my swings. Here's the straight talk on how your data is handled.
TennisWatch uses your Apple Watch sensors to track your tennis swings and provide feedback. Your detailed swing data stays on your device. Only a short game summary is sent, see Analytics below. We collect anonymous usage analytics to improve the app.
TennisWatch processes your swing tracking locally on your Apple Watch and iPhone. Your swing stats, performance metrics, and training data stay on your devices. Anonymous usage data (screens viewed, button clicks, app interactions) and a short summary of each game are sent to Google Analytics to help us improve the app.
We use Google Analytics (by Firebase) to see how the app is used, like which screens get opened and how many games get played. When you finish a game, the app sends a short summary with the score, game length, swing counts and top speed. It never sends your name, your email, your heart rate, your calories or anything from Apple Health. Google also sees basic device info (phone model, iOS version) and a rough, city level location from your IP address. None of this is linked to you or used for ads.
TennisWatch is safe for players of all ages. We don't collect any personal information that identifies users.
We use the following third-party services:
If I ever update this privacy statement, I'll notify you through an app update and post the revised statement here.
