Privacy Policy
Last updated October 19, 2026
The short version
- Your camera video never leaves your phone. MotionPass counts your reps from the camera on the phone itself and doesn't record or upload video.
- We can't see which apps you lock. Apple's Screen Time keeps that private and only gives MotionPass coded tokens that stay on your phone.
- We keep your account, the profile you enter, your workout settings and your workout results, so the app can work and show your progress.
- We use privacy-friendly analytics to see how the app is used. They're tied to a random account ID, never your name or email.
- No ads. We don't sell your data or use it to track you across other apps and websites.
- You can delete your account and history at any time in Settings → Delete account.
Who we are
MotionPass is made by Kinda Smart Inc., the company behind KinesteX ("we", "us"). We're responsible for the personal data described here. If you have any question about it, email support@kinestex.com.
This policy covers the MotionPass iPhone app and its lock screen, and this website.
What we collect, and why
Your account
When you sign up, we collect your email address and a password, or your Apple ID sign-in if you choose Sign in with Apple. With Apple you can hide your email: Apple then gives us a private relay address, and your name only if you choose to share it. Passwords are handled by Google Firebase Authentication. We never see or store them in plain text.
Why: to create your account, sign you in on any phone, and reset your password if you forget it.
The profile you enter
Your name, age, gender, height, weight and activity level. With Sign in with Apple, the name is the one you choose to share with Apple.
Why: to greet you, and to tune your workout and its calorie estimates. These details are passed to the KinesteX workout screen for that purpose.
Your workout settings
The exercises you chose, reps and rests, the time your apps lock each day, whether reps go up automatically, your streak, the days you skipped, and the short note you can write when you skip a day.
Why: so your workout, lock time and streak are the same on any phone you sign in on.
Your workout results
For each workout: the reps counted, form accuracy, estimated calories, how long it took, and when you finished.
Why: to unlock your apps when you reach your goal, keep your streak, and show your history.
Motion data
While you exercise, KinesteX's AI looks at each camera frame on your phone and turns it into a stick figure of 33 body points: shoulders, elbows, hips, knees and so on. That's how it counts reps and checks your form. The video itself is thrown away as soon as each frame is read. It's never recorded, saved or sent anywhere.
When a workout ends, the body points are saved with that workout, along with its reps, accuracy and calories. They let you replay the movement, see your form and read a summary of each set. They can't be turned back into video.
How you use the app (analytics)
We record app events such as "workout started", "workout completed", "break started", "day skipped", "camera allowed", or a tap on the lock screen's buttons. They come with your app version, phone model and iOS version, and are tied to your account's random ID. We also keep a few settings with that ID: your streak, how long your workout is, your exercises and lock time, and how many apps and categories you lock (never which ones). The KinesteX workout screen records similar events about its own screens.
When you skip a day, the note you write is included with that event, so we can see why people skip and make MotionPass fit real life better. Otherwise, analytics never include your name, email, profile details or camera images. Like any internet service, our analytics provider sees your IP address when the app sends events. We've set it not to work out your location from it.
Why: to find what's confusing or broken and make MotionPass better.
Notifications
If you allow notifications, MotionPass schedules a reminder before your lock time on your phone. No notification data is sent to us.
What we don't collect
- Camera video or photos. They stay on your phone and are never recorded.
- Which apps or websites you lock or use. Apple's Screen Time picker gives MotionPass only coded tokens. MotionPass can't read app names from them, and they never leave your phone.
- Your location, contacts, photos, messages or health records from Apple Health.
- Advertising identifiers. We don't show ads or track you across other companies' apps or websites.
Permissions the app asks for
| Permission | What it's for |
|---|---|
| Camera | Counting your reps. Video is processed on your phone and never recorded. |
| Screen Time | Locking the apps you pick until you've done your workout. Apple keeps your choices private. |
| Notifications | An optional reminder before your apps lock. |
| Motion & orientation | Asked by the workout screen, to help you stand your phone at the right angle. |
You can turn any of these off in the iPhone Settings app. MotionPass can't count reps without the camera, and can't lock apps without Screen Time.
Who handles your data
We only share data with the companies that run parts of MotionPass for us, so they can do that job:
- Google Firebase (Authentication, Cloud Firestore, Cloud Functions) stores your account, profile, settings and workout records.
- KinesteX (our own motion-tracking service) runs the workout screen and stores your workout sessions and motion data.
- PostHog stores the analytics described above, in the United States.
- Apple provides Sign in with Apple and Screen Time. If you've chosen to share analytics with developers in iOS, Apple may also send us crash reports.
We don't sell your personal data or share it for advertising. We'd only disclose it if the law requires us to, to protect someone's safety, or as part of a merger or sale of the company. In that last case, this policy would keep applying to your data.
Where your data is stored
Your data is stored and processed on servers in the United States. If you live elsewhere, such as in the EU or UK, it's transferred there under the safeguards those laws require, such as standard contractual clauses with our providers.
How long we keep it
- Account, profile, settings and workout records: until you delete your account.
- Workout sessions and motion data held by KinesteX: until you delete your account and ask us to remove them (see below).
- Analytics: for as long as they help us improve the app. Ask us any time and we'll delete yours.
Your choices and rights
- See and change your data: your profile, workout and lock time are all in the app's Settings.
- Delete your account: go to Settings → Delete account, or Account → Delete account while you're still setting up. You confirm with your password, or with Apple if you signed up with Apple. This deletes your account, profile, settings and workout history right away and removes every lock from your phone. With Sign in with Apple, it also ends MotionPass's access to your Apple ID.
- Delete everything else: to also remove the workout sessions, motion data and analytics linked to your account, email support@kinestex.com from the address you signed up with. We do it within 30 days.
- Get a copy of your data: email us and we'll send it within 30 days.
Depending on where you live (for example, the EU, UK or California), the law gives you rights to access, correct, delete, move or limit the use of your personal data, and to object to some uses. Email us to use any of them. We'll never treat you differently for using them. You can also complain to your local data protection authority.
For people in the EU and UK: we use your data to provide the app you signed up for (performance of a contract), with your consent where the app asks for it (camera, Screen Time, notifications), and for analytics that improve the app (our legitimate interest). You can withdraw consent at any time in iPhone Settings.
Security
Data is encrypted on its way between your phone and our servers. Each account can only read its own records, and our API keys stay on our servers, never on your phone. No system is perfectly secure, but we work to keep your data safe. If a breach ever affects you, we'll tell you as the law requires.
Children
MotionPass isn't meant for children under 13, and we don't knowingly collect their data. If you think a child under 13 has given us personal data, email us and we'll delete it.
Changes to this policy
If we change this policy, we'll update the date at the top. If the change is important, we'll also let you know in the app before it takes effect.
