Questions worth asking before you connect a league

No, and that's deliberate. Rostiro doesn't run your league, score your matchups, or host your draft. ESPN, Yahoo, and Sleeper still do all of that. Rostiro watches all three at once and tells you what to do about what it sees.

Rostiro connects to ESPN, Yahoo, and Sleeper read-only and deep-links you to the exact right screen on each platform's own site to make the move yourself. It never pretends to take an action a platform doesn't actually let a third party take.

It's a density choice, not a skill level. Pick the one that matches how you actually want to play, set it once at signup, and change it anytime.

• Focused. “Tell me what to do.” Five decisions max, the verdict before any reasoning, one tap to act.
• Balanced. “Show me the key stuff.” The call, plus the context that produced it (matchup, injury, weather), visible inline.
• Savant. “Give me everything.” The full data layer: target share, usage trends, projections, nothing hidden. Rostiro advises, it never decides for you.

Mode changes what every screen in the product shows: Pulse, Draft Kit, Lineups, Trades, not just one page.

Rostiro connects to your leagues read-mostly, and encrypts anything sensitive it has to store.

• Sleeper. Public, read-only API, no credentials at all. There's nothing to steal because nothing is stored.
• Yahoo. Official OAuth 2.0, read-only. Rostiro never sees your Yahoo password, only a scoped access token, encrypted at rest with AES-256-GCM.
• ESPN. ESPN has no official API, so private leagues require a browser cookie handshake (espn_s2/SWID). That cookie is encrypted at rest the same way, AES-256-GCM, and used only to read your league's own data.

Access to all three platforms is read-only by construction. Rostiro can't write anything back to any of them even if it wanted to. Full detail is in the Privacy Policy.

Most fantasy apps show you every score whether it matters to you or not. Rostiro filters through a portfolio-relevance rule first: it only interrupts you if a live event directly touches your own roster, your opponent's roster, or the waiver wire in a league you're actually in.

A touchdown from a player nobody on either side of your matchup rosters never reaches you. One that does gets named (which player, how many points, which leagues), then clears itself, instead of piling up as a permanent notification you have to manually dismiss.

Yes, forever: one league, Draft Kit, a daily Pulse, and a limited number of AI-assisted start/sit and trade calls per week. No credit card required to start.
