Privacy Policy

This explains what The Playbook Caller collects, why it collects it, who else sees it, and how to get it back or deleted. It describes what the software actually does — not a template.

Who we are

The Playbook Caller is operated by Jorge Marrero, doing business as MiaMetrix ("we", "us"), an individual based in Florida, United States. The service is the website and application at theplaybookcaller.com.

For anything in this policy — access, correction, deletion, or a complaint — write to [email protected].

The short version

What we collect, and why

WhatWhyWhere it lives
Email addressTo create your account, sign you in, send password resets and confirmations, and contact you about the serviceSupabase; the emails themselves are sent by Resend
PasswordTo sign you in. It is hashed by our authentication provider; we never see or store the plain textSupabase
Display name, and team name if you set oneTo show who you are in the app and to label a shared team librarySupabase
Your custom formations and playsThe point of an account: your work syncs between your devicesSupabase, and a working copy in your browser
Shared team library, if you are on a team planSo a coaching staff can share one set of formations and playsSupabase
Email addresses you enter to invite a coachTo send that person an invitation to your teamSupabase; the invitation email is sent by Resend
Subscription status and planTo know what your account is entitled toSupabase and Stripe
Questions you type into Ask the rule book (beta), and when you open or close that panel, together with the rule book, language, plan and formation on screen at the timeTo measure whether coaches want a rules explainer and to learn what they would ask it. See Ask the rule book (beta) belowSupabase; held in your browser until it can be sent
Preferences: theme, rule book, ball spot, and whether you have seen the helpSo the board opens the way you left itYour browser. The rule book and language are also sent with the beta events in the row above, and only then

That is the complete list. We do not collect your location, your contacts or your device identifiers, and we do not build a behavioural profile of you: the beta events above are read only in aggregate, to decide whether to build one feature.

What we deliberately do not do

These are worth stating plainly, because most services cannot:

Who else processes your data

We use five service providers. Each one only receives what it needs to do its job.

ProviderWhat it doesWhat it receives
SupabaseAccounts, database and syncYour email, hashed password, display name, team name, your formations and plays, and the questions and panel events from Ask the rule book (beta)
ResendSends the account emails (confirming your address, password resets and team invitations) from [email protected], and records whether each one was deliveredYour email address, the content of those emails (including the one-time link in them), and delivery events such as bounces
StripeSubscription payments and the billing portalYour email and payment details, which you give directly to Stripe. Card numbers never reach us
CloudflareHosting and delivery of the siteThe usual request data a web server sees, including your IP address, to serve the page and block abuse
Google (Google Workspace)Hosts our email at miametrix.io, including the [email protected] mailbox, where we receive the emails you send us and your replies to our emailsThe emails you send us, including your address and anything you write in them

We do not use any other processor. If that changes, this page changes with it.

Ask the rule book (beta)

We are testing whether coaches want the board to explain, with the rule cited, why a formation is legal or illegal under each rule book. The Ask the rule book (beta) link opens a panel where you can tell us what you would ask. It does not answer yet, and no artificial intelligence is involved.

Where your data is held

All five of our providers (Supabase, Resend, Stripe, Cloudflare and Google) are United States companies. Supabase, Resend, Stripe and Cloudflare process your data in the United States. Google, which hosts our mailbox, keeps email in its own data centres, which are in the United States and in other countries, so emails you send us may be stored outside the United States. If you use the service from outside the US, you are sending your information to the US, where privacy law differs from your own country's.

How long we keep it

Your rights over your data

Wherever you live, we offer all of the following. We do not charge for them and we do not require an account-closure to exercise them.

If you are a California resident: we do not sell or share personal information, and we will not discriminate against you for exercising any right above.

Children

The service is for adults. You must be 18 or over to hold an account, and we ask you to confirm that when you sign up. We do not knowingly collect personal information from anyone under 18.

If you believe a child has given us information, write to [email protected] and we will delete it promptly. A parent or guardian may use the same address to ask what we hold about their child and to have it removed.

Security

The site is served only over HTTPS and enforces it. Every page carries a Content Security Policy that blocks any script or connection we have not explicitly allowed, which is why there are no third-party requests. Passwords are hashed by our authentication provider. Access to your saved work is restricted to your account by database policies. No system is perfect, and we do not claim otherwise.

Changes

If this policy changes in a way that matters, we will change the date at the top and, for a significant change, tell account holders by email. Continuing to use the service after a change means you accept it.
