Privacy Policy
Effective July 2026 · Applies to this site and the Arkonyx Draft Sync browser extension
The short version
We don't collect, sell, or share your data. Everything the extension and this site handle stays in your browser, with one exception: if you create an optional account, we store the email address you sign up with.
What the extension does
Arkonyx Draft Sync runs only on ESPN fantasy football draft-room pages. It reads your draft's league settings and live picks — the same data ESPN already sends to your browser — and forwards them to the draft board so players are marked as drafted automatically. Requests to ESPN's API are made from your own browser session, so your existing login is used without the extension ever copying it. The one cookie the extension reads is ESPN's SWID identifier, used locally to work out which draft slot is yours; it never leaves your browser. Your ESPN password and authentication cookies are never read, copied, or transmitted.
Where your data lives
Draft state (picks, league settings, your board markings) is stored locally in your browser — in the extension's local storage and the site's localStorage — so a page reload doesn't lose your draft. None of it is sent to our servers, and there are no analytics and no tracking. Clearing your browser data or removing the extension deletes everything.
Accounts
Accounts are optional — everything above works without one. If you sign up, your email address and password are handled by Supabase, our authentication provider (the password is stored only as a hash, and we never see it). They are used solely for signing you in and unlocking account-gated rankings. Your signed-in session stays in your browser; the extension relays it between the site and its draft-room overlay panel so you only sign in once, and signing out signs out every instance.
Third parties
The extension communicates with ESPN (to read your draft, using your existing session) and this site (to display your board). If you create an account, Supabase processes your sign-in. No other third party receives anything. This project is not affiliated with or endorsed by ESPN.
Changes & contact
If this policy changes, the effective date above will be updated. Questions can be sent through the extension's Chrome Web Store or App Store listing.
