This policy covers the BowlSense app for iPhone, Android and Apple Watch, the BowlSense sensor, and bowlsense.io ("BowlSense", "we", "us"). BowlSense is operated by Barry Moyes, its founder, in Billings, Montana, who is responsible for your data. This policy explains what we collect, why, who else handles it, and how to delete it.
Account. You sign in with Apple or Google. We receive your email address and, if the provider shares it, your name. If you use Apple's "Hide My Email", we only see the relay address.
Bowling data you enter or import. Games, frame-by-frame pinfall, sessions (practice, league, tournament), the ball you used, your home center, and preferences such as dominant hand.
Your arsenal. Balls you own or want, layouts (scanned or entered by hand), weights, notes and bags.
BowlSense sensor. The sensor records motion while you throw. The raw motion samples stay on your phone. We store the results calculated from them, such as speed, rev rate, axis and positive axis point. We also store each sensor calibration for a ball, together with the layout it was calibrated against, so past throws can be re-analyzed accurately. App versions before 2.2.8 (July 2026) also uploaded each throw's raw motion samples; those copies are kept with your throws and deleted with your account.
Apple Watch. To measure your swing, the watch uploads the short motion recordings around each delivery to your account, along with the wrist metrics calculated from them. During a bowling workout the watch reads heart rate and active energy from Apple Health to show them on the watch; those Health values are not uploaded to us. Workouts are saved to Apple Health.
Camera, video and microphone. Speed Check and Coach Mode analyze video on your device; we don't upload your videos. On iPhone, recorded clips are saved to your photo library; newer versions of the app let you turn this off in Settings → Recordings. Voice commands use your device's speech recognition, which runs on the device where supported; otherwise Apple's speech service may process the audio.
Bluetooth and location. Bluetooth connects the sensor. Some phones require location permission for Bluetooth scanning; we never read or store your location.
Leagues and chat. If you use league features we store your league and team, roster names, teammates' email addresses you enter for invites, availability, and chat messages. Your league game scores and personal bests are posted to your team chat. If you sign up for a league a center has posted, we send your name, email and phone number to that center.
Imports. League Secretary and SyncPassport scores are fetched by your phone from those sites using the league, bowler or link details you provide. We never ask for your passwords to other services. League Secretary imports also copy your team roster names. PinPal, Bowlr and BowlSheet files are read on your phone and saved as games.
Purchases. App purchases are handled by Apple (App Store) and Google (Google Play). On iPhone, RevenueCat manages purchase status using your BowlSense account ID. Sensor orders on bowlsense.io are paid through Stripe, which receives your card, shipping address and phone number; we never see your card number.
Email. We add you to our Mailchimp mailing list only if you ask to join: through a newsletter signup form, by choosing "Email me BowlSense news" at sensor checkout, or by ticking "Also email me BowlSense news" when you use BowlerDNA. If you opt in at checkout, your name, sensor model and shipping address are stored with your subscription. People who ordered a sensor or used BowlerDNA before October 2026 may already be on the list. Every email has an unsubscribe link, and you can unsubscribe at any time.
BowlerDNA (website). When you upload a PinPal backup, we analyze it and save the report with your email. Anyone with the report's link can open it, so share the link carefully. We keep the uploaded backup file itself only if you choose "Share for research". We remove your email from every report after 90 days. Reports you didn't share for research are deleted after 90 days; research uploads (the report and backup file, kept with only a scrambled, hashed form of your email) are deleted after one year. You can delete a saved report sooner with Delete Report on its page.
Notifications. If you allow notifications, we store a push token for your device. Chat notifications (author name, team and a message preview) are delivered through Expo, Apple and Google.
Diagnostics and website analytics. The app and our server send crash reports to Sentry (device type, app version and app state). The website uses Vercel Web Analytics for page and feature usage, and stores random IDs in your browser so votes and ball requests can be counted once.
Anonymous totals. Some features show totals counted across all accounts, for example how many bowlers carry a ball or how many games have been bowled. These totals never show who you are.
"Share anonymous throw data" setting. Earlier versions of the app showed this setting. It never sent your individual throws to community features and it doesn't affect the anonymous totals above, so newer versions of the app remove it.
Things you choose to share. Arsenal share links include only the balls, not your name. Speed Check results you publish show only speed and rev rate. Teammates in your leagues can see your roster name, availability, chat messages and posted scores.
If you turn on Contribute speed check frames in Settings, the app uploads still images taken from your Speed Check videos to help train ball detection. They are stored without your name or profile, but they may show people or surroundings at the lanes, and our storage system may record which account uploaded each image. This is off unless you turn it on, and turning it off clears any images still waiting to upload.
From Improve BowlSense you can send us a copy of sensor captures to help improve accuracy. A contribution contains raw motion data, timestamps, sensor and firmware details, ball layout and calibration, and any test notes you add. It leaves out your name, email, ball nicknames, scores, center and video. It is pseudonymous, not anonymous: we can link it back to your account to honor deletion requests. Nothing is sent unless you choose to. We keep each contribution for 1 year after you send it, then delete it automatically. To have one deleted sooner, email support@bowlsense.io or delete your account.
We share data only with services that run BowlSense for us, or that you ask us to use:
We may also disclose information if the law requires it.
We keep your data while your account exists. To delete it, open Settings → Delete Account in the app, or email support@bowlsense.io from the address on your account.
Deleting your account immediately removes your sign-in, games, throws, arsenal, calibrations, preferences, league and sync records, and the files you uploaded (Apple Watch motion recordings, raw sensor samples uploaded by older app versions, frame and research contributions, community ball photos, and BowlerDNA uploads and reports). We also delete your Mailchimp subscription and your RevenueCat purchase record. Some things work differently:
The steps are also at bowlsense.io/account-deletion.
Data is sent over HTTPS. Database access rules let each account see only its own data. On your phone, sign-in tokens are kept in the system's secure storage, and app data is kept in the app's private storage.
BowlSense is not directed to children under 13, and we don't knowingly collect their data. If you believe a child has given us information, contact us and we'll delete it.
We'll update this page when our practices change and revise the date at the top. For significant changes we'll also tell you in the app.
Questions or requests: support@bowlsense.io.
