Privacy Notice
Version 2026-09-18
HyzerFlip watches you throw and tells you what to fix. This page says
exactly what it keeps to do that, and what you can make it forget.
What we hold
Your username, email address and password.
Why: To let you sign in on any phone and to reach you about your subscription.
Our reason for holding it: Needed to give you the account you asked for.
How long: Until you delete your account.
The stick-figure positions of your body through each throw, and the coaching the app worked out from them.
Why: This IS the coaching. Your progress, your streak and every comparison against an earlier session are built on it.
Our reason for holding it: Needed to give you the coaching you asked for.
How long: Until you delete your account.
The video your camera recorded of a throw.
Why: So the Throws tab can play your throw back and coach you through it.
Our reason for holding it: Needed for the throw log, which is part of Pro.
How long — Free: Nothing. Your throw video is analysed and deleted straight away on the free tier.
How long — Pro: Your newest 10 throws keep their video. Older ones are deleted automatically, and everything goes when you delete your account.
A copy of each throw's stick-figure positions under a random code instead of your name.
Why: To improve the coaching for everyone — spotting what most players get wrong.
Our reason for holding it: You agree to this when you sign up, and you can switch it off in Setup at any time.
How long: Until you delete your account.
YOU CAN SWITCH THIS OFFYour plan, and the customer number Stripe gives us.
Why: To know what you have paid for. Card numbers are typed on Stripe's own page and never reach this app.
Our reason for holding it: Needed to take a payment you asked to make.
How long: Until you delete your account.
Who else sees it
Nobody sells it and nobody buys it. Three companies touch it because the app
runs on them: our hosting provider stores the files, Stripe takes the payment
(card details are typed on Stripe's own page and never reach us), and your
phone's own browser does the body tracking — the pose engine is served from
this app, not from anyone else's network.
Your throw video and your throw log are yours. Nobody else's account can
open them, and requests for one you do not own are refused.
What you can make us do
- See everything we hold about you — Setup > Your data > Download my data, or ask us.
- Correct something that is wrong — Ask us.
- Delete your account and everything in it — Setup > Your data > Delete my account. It is immediate and final.
- Take your data elsewhere — The download is machine-readable JSON.
- Stop the optional use — Setup > Your data, the one switch.
- Complain to a regulator — Your national data protection authority; in Denmark, Datatilsynet.
Deleting your account is immediate and irreversible: the throws, the videos,
the coaching history and the copy used to improve the app all go in the same
action. There is no recovery afterwards.

ask a parent to set the account up with you.
