F&M collects limited pseudonymous product-usage events to understand how the product is used and to improve it.
Some stored field and schema names still begin with fcc_
— fcc_product_event, fcc_decision_ledger, and the keys this
site writes in your browser. Fantasy Command Center was this product's working
name, and those identifiers were left alone deliberately: renaming them would break
compatibility with records that already exist and with settings already saved in your
browser. They are the same product described here, not another service.
This page describes F&M's product-usage telemetry specifically. It is not a description of everything the application handles: F&M obviously reads your league, roster and player data from your fantasy provider in order to work at all. Where a statement below applies only to telemetry, it says so.
Two references in each event are replaced with a keyed hash before they are stored — your league reference and a per-visit reference. The key stays on the server and is never sent to your browser.
That makes them pseudonymous, not anonymous. The same league produces the same hash each time, which is deliberate: it is what allows F&M to see that a situation recurred rather than treating every observation as unrelated. We do not describe this telemetry as anonymous, because it is not.
Every field is a fixed name from a published list. An event containing anything else is rejected rather than stored.
espn_s2 or
SWID value — is rejected whole. It is not redacted and
partially kept, because a partially-kept record is still a record nobody
intended to create.Separately from telemetry, the app remembers a few preferences in your browser's local storage so it works the way you left it: your Sleeper username, your colour theme, any ESPN league IDs you added, and — if you entered them — your ESPN cookies.
These stay on your device. They are not telemetry, they are never sent to F&M's collection endpoint, and none of them appears in any stored event. The ESPN cookies are sent only to this site's own proxy, inside a POST body, in order to read your ESPN league on your behalf. Clearing your browser storage removes all of them.
F&M has an optional research mode, off unless you turn it on in Settings. With it on, each decision card gains a Log decision button. Pressing it saves a snapshot of that decision — what F&M recommended, the projected impact, the evidence behind it and the alternatives it considered — so the decision can be evaluated later against what actually happened.
It does not affect your recommendations. Telemetry is written after a recommendation has already been produced and displayed. It is never an input to F&M's lineup, waiver or trade analysis, and a telemetry failure cannot change what F&M advises.
F&M cannot tell whether you acted on a recommendation. F&M never writes to your fantasy platform — it makes no claims, no adds, no drops, no lineup changes and no trades. It can record that you opened the reasoning behind a suggestion. It has no way to know whether you then made that move in Sleeper or ESPN, and it does not try to infer it.
Some builds of F&M show a Send feedback link in the footer. It is an ordinary link to the F&M owner's own contact address — it opens your mail client or a page you can see. Clicking it sends nothing. Nothing is submitted, and nothing about your session is attached.
If a build has no such link, the beta's feedback channel is simply the invitation you received — replying to it reaches the same person.
Events are sent to F&M's own collection endpoint and stored in a private repository controlled by F&M. They are not sold, not shared with advertisers, and not sent to a third-party analytics product.
F&M is served by Cloudflare, which processes the network request itself, and the telemetry archive is hosted on GitHub. Your fantasy data comes from Sleeper or ESPN as applicable, and player market values from FantasyCalc.
F&M is a small beta and does not currently enforce an automatic retention or deletion schedule for these events. We would rather say that plainly than name a period we do not actually apply.
If you would like the pseudonymous events associated with your league removed, contact the F&M owner and we will remove them.
If what F&M collects changes materially, this page changes with it. The date at the top is the last update.
This page describes what F&M actually does. It is a factual disclosure for a beta product, and it does not by itself constitute a claim of compliance with any particular privacy regulation.
