Roster Locker ("we," "us") is an AI-powered fantasy sports assistant. This policy
explains what we collect, why, and the choices you have. We've tried to write it in
plain English rather than legalese.
The short version: We collect your email and the
fantasy league data you choose to connect. We never ask for or store your platform
passwords. We don't sell your data. You can delete your account and data at any time
by contacting us.
Information we collect
Account information: your email address, a password (stored only
as a secure one-way hash — we can't see it), and an optional display name.
Fantasy league data: when you connect a league, we import public
or authorized data such as your rosters, league settings, draft history, and matchups
from the platform you choose (Sleeper, ESPN, Yahoo, MyFantasyLeague, Fleaflicker, Fantrax,
and Fantasy Premier League). We connect using each platform's
public or sanctioned method (for example, a username, a league ID, or an official
OAuth sign-in). We never ask for, store, or use your platform passwords.
Private-league credentials (only if you provide them): for private
ESPN leagues, you may optionally supply browser cookie values so we can read that league.
These are encrypted before storage and used only to sync that league.
Usage data: basic technical information such as your device type,
and the questions and requests you make to the AI so we can generate answers and improve
the product.
Waitlist email: if you join our waitlist, we store your email
address to notify you about launch and early access.
How we use your information
To provide the service — importing your leagues and generating AI analysis grounded
in your actual rosters and scoring settings.
To send you account-related email (for example, password reset links).
To respond to feedback and support requests.
To operate, secure, and improve the product.
AI processing
Roster Locker uses third-party large language models (currently Google's Gemini) to
generate analysis. When you ask the AI a question, the relevant context (such as your
roster and league settings) is sent to that provider to produce a response. We use these
providers under terms intended to keep your data out of their model training. We do not
use your personal fantasy data to train our own models.
How we share information
We do not sell your personal information. We share it only with service
providers who help us run the product, under agreements that limit their use of it:
Fantasy platforms — to read the leagues you connect.
AI providers — to generate analysis (see above).
Email provider — to send transactional email.
Payment provider — if and when you subscribe, billing is handled by
a third-party processor; we don't store your full card details.
Legal reasons — if required by law or to protect our rights and users.
Yahoo Fantasy
When you connect a Yahoo account, we read your Yahoo fantasy data live at the moment you
ask for analysis and do not store, cache, or index it in our database. Fantasy data sourced
from Yahoo is provided by Yahoo Fantasy. Yahoo Fantasy integration covers NFL, NBA, MLB, and
NHL and is available to users in the United States and Canada.
Data retention and deletion
We keep your data while your account is active. You can request deletion of your account
and associated data at any time by contacting us at
support@roster.locker. We may retain limited
records where required for legal or security reasons.
Cookies and local storage
We keep things minimal. We do not use third-party advertising or cross-site tracking
cookies. The app uses your browser's local storage to keep you signed in (for example,
your session token) and to remember basic preferences. If we add privacy-respecting
product analytics or error monitoring in the future to improve the service, we'll update
this policy to say so.
Security
Passwords are hashed, sensitive credentials are encrypted at rest, and connections are
served over HTTPS. No system is perfectly secure, but we take reasonable measures to protect
your information.
Your rights
You can:
Access the personal data we hold about you.
Correct inaccurate information (for example, your display name).
If you're a California resident, you have the right to know what personal information we
collect, to request its deletion, and to not be discriminated against for exercising these
rights. We do not sell or share your personal information as those terms are
defined under California law. To make a request, contact
support@roster.locker.
Children
Roster Locker is not directed to children under 13, and we do not knowingly collect their
information.
Governing law
This policy is governed by the laws of the United States and the State of Hawaii, without
regard to conflict-of-laws principles.
Changes to this policy
We may update this policy as the product evolves. We'll revise the "last updated" date
above and, for significant changes, notify you.
