Apps pro.js: offline Pro keys (Ed25519) + direct checkout map (Workers cap fix, 17 Oct 2026)

bdc2129 verified 5 days ago

13.7 kB

/* CyberMax Pro unlock with plans, for static web apps (copied into each product's web/ folder; each product stays
 * self-contained). Extends pro.js with several plans (monthly, yearly, one-time) and a re-check for subscriptions.
 * Config before this script:
 *   window.CMX_PRO = { id, name, perks: [..], plans: [{ offer, label, price, per, note, best }], free: "one line" }
 * Buy: counted link https://data.cybermaxtools.com/buy/<offer>?s=app-<id> -> Stripe Payment Link.
 * After checkout Stripe sends the buyer to data.cybermaxtools.com/unlock/<id>?session_id=..., which checks the
 * Checkout Session (and, for a subscription, that it is still active) and returns here with #cmx-pro=<session id>.
 * The app checks that code once (/unlock/<id>?json=1&session_id=..) and remembers Pro in this browser; it re-checks every
 * 3 days, so a cancelled subscription turns off by itself (one tiny request per buyer every 3 days, none for free users).
 * The same code (shown on the receipt page and in the Pro box) unlocks Pro on another device. No account, no tracking.
 * (c) 2026 CyberMax. All rights reserved. */
