Introduction

Baseball Mechanics (“the App,” “we,” “us,” or “our”) is a mobile application that uses artificial intelligence to analyze baseball pitching, hitting, and catching mechanics. Many of the players analyzed in this App are children, and we treat that as the central fact of this policy rather than a footnote.

This policy covers the Baseball Mechanics mobile app for iOS and Android and the companion web portal we operate for the same accounts. Both are backed by the same database and the same servers — see Section 12.

It explains what we collect, where it is stored, who processes it, and what you can do about it. By using the App, you agree to the practices described here. If you do not agree, please do not use the App.

1. Information We Collect

1.1 Information You Provide at Setup

Player name (required) — personalizes analysis reports.
Your date of birth (required) — the date of birth of the person setting up and owning the account. We use it to verify your own age and to determine when the protections in Section 5 apply. It cannot be skipped, because the protections in Section 5 are impossible to apply to an account whose owner’s age we never asked for.
The player’s date of birth (optional) — collected only when the account holder is setting the App up for someone else, such as a parent or coach entering a player. It is used solely to place the player in the right age division and to age-calibrate their analysis. It is stored on your device with that player’s profile, not on your account record.
Email address (optional for account holders 13 and over; required for under-13 accounts, where it must be the parent’s or guardian’s — see Section 5).
Marketing preference — whether you ticked the optional box to receive product-update emails. It is off unless you turn it on.

We no longer ask you to declare whether you are a player, a coach, or a parent. Earlier versions of the App collected that as a “role”; it was removed, and the App does not record it for new accounts.

1.2 Account

The App creates an account for you. If you provide an email address you receive a cloud account (sign-in by one-time code; we never see or store a password). If you do not provide one, the App signs you in anonymously — a random identifier with no personal information attached to it.

On iOS, your account identifier deliberately survives deleting the App. We store your sign-in token in the iOS Keychain, which Apple does not clear when an app is removed, so reinstalling returns you to the same account and the same history rather than a blank one. See Section 6 for what this means for deletion.

The web portal signs in with an email address and a password you set, because a browser cannot receive a one-time code the way the App can. It is the same account either way.

We do not collect payment card numbers, government ID numbers, or precise location.

1.3 Video Frames You Submit for Analysis

You select a video from your device and the App extracts still frames at specific mechanical positions. Those still images — not the original video — are sent to our server for AI analysis, and they are not retained after the analysis completes. We never receive or store the original video file, and there is no library, archive, or training set of user video anywhere in our systems.

The frames are analyzed for body position and movement. They are not used for facial recognition and are not matched against any identity database.

Please do not capture frames containing people other than the player being analyzed.

1.4 Analysis and Session History

Your analysis results (mechanics scores, identified strengths and weaknesses, recommended drills) are stored on your device. If you have a cloud account, they are also stored on our servers so they are available across your devices and over time.

1.5 Recruiting Profile (optional)

If you choose to create one, we store and sync the fields you fill in. That is more than a name and a position, so here is the full list:

Athletic and identifying: graduation year, height, weight, bats/throws, primary position, secondary position
Affiliation: high school, travel ball team, state
Academic: GPA and SAT/ACT scores, if you enter them
Measurables: 60-yard dash, exit velocity, pitch velocity, pop time, if you enter them
Your mechanics scores, carried over from your analysis history
Your chosen visibility setting (Section 4)

Every one of these is optional and self-entered — leave any of them blank and we store nothing for it. Recruiting profiles are stored in our cloud database so they can be shown to the people you choose in Section 4.

This feature is switched off entirely for players under 13 and cannot be turned on.

Player photos are not part of this. If you add a photo to a player’s profile, it stays on your device. We do not upload it, and there is no photo storage in our systems.

1.6 Coach Verification of Measurables (optional)

A self-entered measurable is a claim. If an athlete wants one confirmed, they can ask a coach to verify it, and that creates records:

The athlete supplies the coach’s email address and we email that coach a one-time link. That address is a third party’s personal information, provided to us by the athlete — please only enter the address of a coach who expects to hear from you.
We store the measurable, the exact value at the time it was submitted, the outcome, any note the coach adds, and the date. The value is snapshotted deliberately: if the athlete later edits the number, the record still shows what was actually verified, rather than lending a coach’s name to a different figure.
If the coach has an account, we store their name and their school or team so a verification can be attributed and can outlive their move to another club.

Verification is not offered to athletes under 14, and it is withheld when we cannot establish an age. Verification records are an audit trail and are kept even if the underlying profile is later changed — see Section 6.

1.7 Team Data (optional)

If a coach creates a team, we store the roster and the members’ mechanics scores so the coach can see team-level progress.

1.8 Subscription Status

If you purchase a subscription, we store whether you have an active subscription and which one. Payment is handled entirely by Apple or Google — we never see or store your payment details.

We also record the steps of an upgrade: that you reached the free-analysis limit, that the upgrade screen opened, which plan button you tapped, and whether the store purchase completed, was cancelled, or failed (with the store’s error code). Each step is stored with your account identifier, your subscription platform identifier, the plan and its price, and your platform, app version and build. It contains no name, email address, player information, or video. We use it only to understand where upgrades break or are abandoned. It is never sold and never used for advertising.

1.9 Diagnostic Information

If the App hits a technical error we receive a report containing the error, the screen or feature it happened on, your device model, operating system, app version and build, and your account identifier. It does not include your name, your email address, or any player profile information. Used only to fix technical problems; never sold, and never used for marketing. Reports are kept for up to 90 days or until you delete your account, whichever comes first.

1.10 How You Found Us

If you arrive through a campaign link, a printed QR code, or a code you type in at setup, we record which code it was and which of those routes it came through. We use it to understand which outreach works. It grants nothing, unlocks nothing, and is not linked to anything you do in the App beyond the fact that you arrived.

If you reached us through our website first, that code may be held in a cookie on our own site so it survives the trip to the app store. It is a first-party cookie for that single purpose. We run no advertising cookies and no third-party trackers.

1.11 What We Do NOT Collect

Precise or approximate GPS location
Contacts, call logs, or messages
Browsing activity outside our own app and website
Advertising identifiers or cross-app tracking data
Biometric identifiers, facial recognition data, or voiceprints
Payment card or bank account information

2. How We Use Your Information

Information	How It Is Used
Name, dates of birth	Personalizing and age-calibrating analysis reports; applying the age protections in Section 5
Email address	Signing you in, syncing your data across devices, sending your results PDF, support
Video frames	Processed by AI to produce your mechanics analysis, then discarded
Analysis history	Showing progress over time; team and recruiting features you opt into
Recruiting profile	Shown to coaches and recruiters only at the visibility level you chose
Verification records	Showing whether a measurable was confirmed by a coach, and what value they confirmed
Coach’s email address	Sending the one-time verification link the athlete asked us to send
Subscription status	Unlocking paid features and enforcing usage limits
Upgrade steps	Finding where upgrades fail or are abandoned
Diagnostics	Fixing crashes and bugs
Campaign code	Measuring which outreach brings people to the App

We do not:

Sell, rent, or license your personal information to anyone
Build advertising profiles or track you across other apps and websites
Send you marketing email unless you explicitly opted in — and you can opt out at any time by emailing us
Use your video or analysis data to train AI models
Make automated decisions producing legal or similarly significant effects. Mechanics scores are coaching feedback, not an assessment of a person.

3. Who Processes Your Information

Processor	What it handles	Where
Anthropic, PBC — privacy	The video frames, for AI analysis. Not retained by Anthropic for training.	US
Supabase, Inc. — privacy	Our cloud database: your account, profile, analysis history, recruiting, verification and team data, and technical error reports.	US
Render Services, Inc. — privacy	Backend hosting; your requests pass through it.	US
Vercel Inc. — privacy	Hosting for our website and the web portal; browser requests to them pass through it.	US
RevenueCat, Inc. — privacy	Subscription status. No payment details.	US
Apple / Google	Payment processing for subscriptions. We never receive your payment details.	US
Google (Gmail) — privacy	Delivering results emails, verification links, and notifications of technical error reports.	US

We may also disclose information where required by law, or where necessary to protect the rights, property, or safety of our users or the public.

4. Recruiting Profile Visibility — You Control This

If you create a recruiting profile, you choose who can see it:

Private — nobody but you.
Coaches only — the coaches of teams you belong to. This is the maximum for any player under 13.
Recruiters — visible to recruiter accounts in the App’s search and discovery tools. Those tools require a signed-in account; they are not open to the public web.
Public — additionally reachable through a shareable link you can send to a college coach who does not use the App. The link contains a long random identifier; it cannot be guessed, but anyone you send it to can open it, so share it deliberately.

You can change the visibility or delete the profile at any time. Lowering the visibility immediately stops it being served at the higher level.

5. Children’s Privacy (COPPA)

Baseball Mechanics is used to analyze children, and we designed this section on the assumption that the player is a minor unless we know otherwise.

5.1 Date of birth is required

We ask for the account holder’s date of birth at setup and it cannot be skipped. That is the date the protections below are keyed to, because the account holder is the person who agrees to this policy, owns the account, and receives our email. Whether that person is under 13 is determined from this date of birth, and that determination is calculated and enforced on our servers, not left to the app alone.

If the account holder is setting the App up for someone else, they may also give the player’s date of birth. That one is optional, it stays on the device with that player’s profile, and it is used only to place the player in the right age division and age-calibrate their scoring. If it is not given, the App asks about the player’s age at analysis time instead.

If we cannot establish a player’s age, we apply the stricter treatment, not the looser one — an unknown age is treated as a child, and features gated on age stay switched off.

If the account holder’s date of birth shows they are under 13, the account can only be set up by a parent or legal guardian. Setup does not activate the account. Instead:

The guardian provides their own email address, which becomes the owner of the account and must be verified by a one-time code we email at sign-in.
We then email that address a unique, single-use confirmation link. The account stays locked and cannot be used until the guardian clicks it. Clicking the link is the guardian’s verifiable consent, and we record the date and time it occurred.
Shortly after, we send a second confirmation email to the same address, which also contains a link to withdraw consent at any time.

This “email-plus” process is a verifiable parental consent method permitted under COPPA because a child’s information in this App is never disclosed publicly — every under-13 player is restricted to coach-only visibility (see Section 5.1). Until a guardian completes step 2, no analysis, profile, or other data for that player is used beyond what is strictly necessary to hold the pending account.

5.3 Under-13 players are never published

For any player under 13, recruiter and public visibility are switched off and cannot be turned on. Their recruiting profile can be shared with the coaches of their own team and no further. It is never listed in recruiter search, never returned by discovery, and never reachable by a public link. This is enforced in the App and independently enforced again on our server, so it cannot be bypassed by a modified client.

Coach verification of measurables (Section 1.6) is not offered below age 14 at all, and is withheld entirely when the age is unknown.

5.4 Marketing

We do not send marketing email to children. The only address on an under-13 account is the guardian’s, and it receives product-update email only if the guardian themselves opted in.

5.5 Parental rights

A parent or guardian may review or delete their child’s data at any time by emailing mechanicssupport@gmail.com from the guardian address on the account. We respond within 30 days. If we learn we have collected personal information from a child under 13 without parental consent, we delete it promptly. A guardian may also withdraw consent instantly using the link in the confirmation email, or from within the app’s pending-consent screen; doing so locks and then deletes the child’s account and data. —

6. Data Retention

Data	Retention
Video frames	Not retained. Discarded as soon as the analysis is generated.
Account, profile, analysis history	Kept until you delete your account or ask us to delete it.
Recruiting profile	Kept until you delete it or delete your account.
Verification records	Kept as an audit trail after the profile they describe is edited or removed, because their purpose is to record what was confirmed and when. Deleted with your account on request.
Team data	Kept while the team exists.
Campaign code	Kept for as long as the account exists.
Local data on your device	Removed when you uninstall the App — except your sign-in token on iOS, which the operating system preserves so a reinstall returns you to your own account (Section 1.2). Cloud data is not removed either — uninstalling does not delete your account; email us to do that.
Diagnostic reports	Up to 90 days, or until you delete your account, whichever comes first.
Upgrade steps	Up to 365 days, or until you delete your account, whichever comes first.

7. Data Security

All traffic between the App and our servers uses encrypted HTTPS.
Our database enforces row-level security: your rows are readable only by your account.
API keys and credentials live in server-side environment variables and are never shipped in the App.
Verification links are single-use and time-limited, and we store only a hash of the link’s token — never the token itself.
Cloud backups are encrypted.

No system is perfectly secure, and we cannot guarantee absolute security.

8. Your Rights and Choices

Everyone:

Access — email us for a copy of your data.
Deletion — request account deletion, in the app or by email, and we will delete your account and its cloud data. Uninstalling removes the local copy but not the cloud copy.
Correction — edit your profile in the App.
Withdraw marketing consent — email us; it takes effect immediately.
Control recruiting visibility — change it or delete the profile in the App at any time (Section 4).

California residents (CCPA): you may know what we collect, request deletion, and opt out of sale — we do not sell personal information — without being discriminated against for exercising these rights.

EEA / UK residents (GDPR): you have rights of access, rectification, erasure, restriction, objection, and portability. Our legal bases are consent (email, marketing, recruiting publication, verification), contract (delivering the analysis you asked for), and legitimate interest (diagnostics, security, and knowing which outreach brought you here). Where the user is a child, consent is given by the holder of parental responsibility.

To exercise any of these, contact mechanicssupport@gmail.com.

9. Third-Party Links and Advertising

The App contains no third-party advertising and no tracking pixels. AI-generated analysis may refer to professional baseball generally; no MLB, team, or player affiliation, endorsement, or partnership is implied or exists.

10. Changes to This Policy

We may update this policy. When we do we revise the “Last Updated” date above. If a change materially affects how we collect or use personal information, we will notify users in the App.
