Privacy

What MyGM does and does not collect.

Summary

MyGM is a read-onlyModel Context Protocol connector. It reads public Sleeper league data via Sleeper's public API and presents it back to you and to Claude. It does not collect, store, sell, or share any personally identifiable information.

What we read

  • Sleeper league rosters, matchups, transactions, drafts, and standings — sourced from the public api.sleeper.app endpoints.
  • NFL player metadata and weekly stats / projections — also from Sleeper's public API.

All upstream data is already public on Sleeper. MyGM never sees your Sleeper password, account email, payment info, or any credentials.

What we cache

  • League history snapshots, slim NFL player index, and weekly stats / projections are cached in Vercel Blob (cache/...) to reduce upstream load. Cached data mirrors the public Sleeper data — nothing additional.
  • No per-user identifiers are stored alongside the cached data.

Logs

Vercel function logs may contain transient request IPs / user agents (standard infra logging). These rotate per Vercel platform retention. They are not joined to any user profile by MyGM.

Tracking

MyGM has no analytics scripts, no advertising pixels, no third-party trackers. The site does not set cookies for tracking.

Rate limiting

The API endpoints (/api/mcp, /api/dashboard, /api/widgets) are protected by an in-memory per-IP token-bucket rate limiter to deter casual abuse. It uses only the request IP and User-Agent for that check and does not store them or link them to any user identity.
