Privacy Policy

Last updated: November 5, 2026

Draft for legal review. This describes what the product does today, checked against the code. Before the app goes to a store, a lawyer who handles children’s privacy (COPPA and state law) should read it, and the contact block below (K6 Labs LLC, Nashville, Tennessee, with an email) should be confirmed, and a street address added if they ask.

0FFDAYS helps young athletes train on their own between practices. A phone counts their reps, and their coach sees that the work was done. This page says what we collect, why, who sees it, and how a parent controls it.

The short version

Video is not uploaded. The camera is used on the phone to count reps. The video is analysed on the phone and is not sent to us or stored.
One exception, and only if a parent turns it on. A parent can allow their child to choose a single short clip to send to their coach for feedback. It is off by default, never automatic, deleted after 30 days, and deleted at once if the parent turns it off.
A parent is in charge. For athletes, a parent or guardian signs up first, decides whether the child may train, and sends the child their link. Nothing starts until they say yes.
No advertising, no selling data, no tracking across other apps or sites.

What we collect

What	Why	From whom
Name, and birth year (not full birthday)	To put an athlete on a team and give age-appropriate training amounts	The program’s roster, or the parent
Parent or guardian name, email and mobile number	To invite the parent, and so the program can reach them	The program’s roster, or the parent
Coach and director name, email and mobile number	To sign them in and send them their team’s summary	The director, or the person themselves
Training results: which drill, how many reps, which hand, how long, when	So the athlete and their coach can see the work	The athlete’s phone, as they train
Sound from the microphone	To hear the ball hit the wall and count it. It is processed on the phone and is not recorded or sent	The athlete’s phone
Motion sensor readings	To check the phone is propped up steady. Not sent	The athlete’s phone
A short video clip	Only if a parent has allowed it and the athlete chooses to send it to their coach	The athlete, one clip at a time
A program’s logo	To show the club’s badge on its screens	The director

We do not ask for a child’s home address, school, photo, precise location, or social media accounts.

Who can see it

The athlete sees their own results.
Their parent or guardian sees their child’s results and everything sent to the child.
Their coach and the program’s director see the results of athletes on their teams. They never see video unless a clip was sent as described above.
Rankings are seen only by the coaches and directors of the program. Athletes and parents are never shown a ranking of other children; athletes earn badges for their own progress instead.
Other programs cannot see anything about your program.

Who else handles the data

Our hosting provider, where the service runs and the data is stored.
An email provider, only once a program turns on sending. Until then the program sends invitations from its own email.
YouTube (Google), only when an athlete opens a film-study clip. The clip plays in YouTube’s own player, in its privacy-enhanced mode, so that athlete’s browser talks to YouTube while it plays. We do not download or store the video, and we do not send YouTube who the athlete is. An athlete who never opens a clip never contacts YouTube at all.
TeamSnap or SportsEngine, only if a director chooses to connect one. We read the team’s roster from it, with the director’s permission. We do not send anything back.

We do not use advertising networks or analytics services that follow people.

Parents’ controls

From the parent’s page, at any time, without contacting us:

Say no, or take back a yes, to the child training.
Turn clip sharing on or off. Turning it off deletes clips already sent.
Download everything held about their child.
Delete their child’s data.

How long we keep it

Session results: kept while the athlete is in a program, and until deleted.
Rep-by-rep timing: pruned after 45 days.
Shared clips: deleted after 30 days.
Deleted data is removed from the live service; it may remain in encrypted backups until they are replaced.

Children

0FFDAYS is used by children, including children under 13. A child cannot start using it until a parent or guardian has signed up, been told what is collected, and said yes. A coach or director cannot give that permission for a parent. If you believe a child is using 0FFDAYS without a parent’s agreement, contact us and we will remove the account.

Security

Sign-in codes are stored only as one-way hashes. Connections are encrypted. No system is perfectly secure, and if something goes wrong that affects you, we will tell you.

Changes

If this changes in a way that matters, we will say so inside the app before it takes effect, and parents will be asked again where the change needs their permission.
