Terms of service

Last updated 2026-07-11

What this is

Flip Goblin shows market data and analytics for Old School RuneScape's Grand Exchange, plus an optional RuneLite plugin that tracks your own trades. It's an information tool: prices can be wrong, delayed, or manipulated by other players, and nothing here is advice. Decisions you make in the game are yours.

The plugin plays by the rules

The plugin is informational only — it never automates gameplay, never places or modifies offers, and never acts on your behalf. Everything it could send off your machine is opt-in and disclosed (see the privacy policy). You use RuneLite and its plugins under Jagex's and RuneLite's own terms.

Your account

Don't abuse the service: no scraping past published limits, no submitting fabricated market data, no attacking the infrastructure, no using someone else's account. We can suspend accounts that do. You can delete your account (and everything in it) any time from Settings.

Premium

Premium is a monthly or yearly subscription billed by Stripe, cancellable any time from the billing portal — you keep premium until the end of the period you paid for. If a paid feature is materially broken for a sustained period, contact us via feedback and we'll sort it out.

No warranty

The service is provided as-is, without warranty of any kind. To the maximum extent permitted by law, we are not liable for losses (in-game or otherwise) arising from your use of the service, including from data errors or downtime.

Trademarks

Old School RuneScape and Jagex are trademarks of Jagex Ltd. Flip Goblin is a fan-made tool and is not affiliated with or endorsed by Jagex. Price data courtesy of the OSRS Wiki real-time prices API.

Changes

We may update these terms as the product evolves; material changes will be noted on this page's date stamp.
