Terms / updated August 23, 2026
A research tool, not a promise of return.
These terms state the commercial and operating boundaries in plain language. Stripe is the primary payment processor; Gumroad may be offered as an alternate.
License
Your $499 one-time purchase licenses one copy of eagL for personal research and trading workflows on devices you control. You may not resell, redistribute, reverse engineer, or share the application, activation file, or signing material.
Updates
The purchase includes every version 1 update and improvement released for the lifetime of version 1. The purchased build and its updates remain usable permanently. There is no subscription or automatic renewal.
Future major versions
Version 1 is licensed to you permanently, keeps receiving version 1 updates for the lifetime of version 1, and does not stop working when a later major version is released. The future version 2 — the v2 Pro Edition — will be a separate release with its own price. Every version 1 licence holder qualifies for 20% off the v2 Pro Edition at release: claim it by emailing a copy of your licence confirmation to eaglapp@proton.me. Eligibility follows the licence issued with your order; no release date for version 2 is promised.
Sales and support
All sales are final. Support at orders@eagl-app.com or eaglapp@proton.me — either address reaches the same person — assists with failed downloads, missing activation files, installation on the supported macOS build, and questions about the product. Duplicate or erroneous charges are corrected as billing errors. Market-data quality, trading results, venue outages, and losses are never grounds for a refund. The full policy is set out on the sales-terms page.
Supported environment
The launch build supports Apple Silicon Macs running macOS 11 or later. Internet access and separately obtained provider credentials are required for live market data. Platform or provider changes can affect availability.
Trading responsibility
eagL is analytics software. It is not financial, legal, or tax advice; it does not promise profitable trades; and live execution is disabled by default. You remain responsible for every order, venue account, credential, and compliance obligation.
Availability and liability
Market data, calculations, alerts, and third-party services may be delayed, incomplete, wrong, or unavailable. The software is provided as-is to the maximum extent permitted by law. Nothing in these terms excludes rights that cannot lawfully be excluded.
