Fantasy Fiend / Legal

Privacy Policy

Effective date: April 27, 2026

The short version

Fantasy Fiend is a private friends-and-family beta operated by Slingshot Frontiers. We collect the data we need to power your league's AI, we don't sell it, we don't share it with sportsbooks, and you can ask us to delete it whenever you want. If anything below is unclear, email legal@slingshotfrontiers.com and ask.

1. Who we are

Slingshot Frontiers ("we," "us," "our") operates the Fantasy Fiend app (the "App"). Fantasy Fiend is the product name; Slingshot Frontiers is the legal entity behind it.

2. What we collect

To make the App work, we collect three categories of data:

  • Account data. When you sign in, our auth provider (Clerk) stores your email, name, and a session cookie. We see your Clerk user id and basic profile fields.
  • Fantasy league data. When you connect an ESPN, Sleeper, or Yahoo league, we read your matchups, standings, draft picks, transactions, rosters, and member metadata via those platforms' APIs. We store it on our servers so the AI can answer questions about your league's history.
  • Query telemetry. When you ask the Fiend a question, we log the prompt text, the tools the pipeline ran, the answer it produced, and timing/cost metadata. This is how we improve the product and debug issues.

We do not collect payment cards (the beta is free), geolocation, contacts, or anything else not listed above.

3. How we use it

Your data is used for one purpose: powering Fantasy Fiend for you. Specifically:

  • Answering your questions to the Fiend with data-backed responses
  • Generating Museum exhibits, narratives, and league analytics
  • Debugging bugs you report
  • Improving accuracy of the AI based on aggregate query patterns

We do not sell your data. We do not share it with advertisers, sportsbooks, fantasy platforms, or any other third party for their own use.

4. Where it lives

Your data lives on servers we operate (Postgres + Apache AGE for the graph layer, hosted in US-East). Backups are encrypted at rest. Auth session data lives with Clerk per their privacy policy.

5. Cookies

During the beta we use exactly one type of cookie: the Clerk authentication session cookie, which keeps you signed in between visits. We do not run analytics cookies, ad-tracking pixels, or third-party trackers during the beta.

6. Your rights

You can, at any time:

  • Ask for a copy of the data we hold about you
  • Ask us to delete the personal information we hold about you — see how deletion works below
  • Disconnect a fantasy platform without deleting your account
  • Walk away entirely — just stop using the App and tell us

When you ask us to delete your data, we'll remove it from our active systems within 30 days. Copies may remain in our encrypted backups until they're overwritten in the normal course (up to ~6 months), after which they're permanently deleted — we won't restore deleted data from a backup except to keep a restore intact. We may retain limited information where the law requires it or to resolve a dispute or prevent abuse, and we may keep anonymized data that can no longer be linked to you.

To exercise any of these, email legal@slingshotfrontiers.com. No forms, no support tickets — it's a friends-and-family beta and we'll handle it directly.

7. Children

Fantasy Fiend is for adults. The beta-tester agreement requires you to be at least 18 years old. We don't knowingly collect data from anyone under 18.

8. Security

We take reasonable technical and organizational measures to protect your data, but this is a private beta — not a battle-tested production system. Don't store anything in the App that you couldn't live with becoming public if something went wrong. (See the Terms of Service §5 for the warranty disclaimer.)

9. Changes to this policy

If we make material changes during the beta we'll email beta testers and update the effective date above. Continuing to use the App after changes means you accept them.

10. Contact
