1. Pricing engine: set a price, pick a fan count

Monthly price per member $9.00

Paying members 1,200

Platform cut 10.0%

include card processing at 2.9% + $0.30 per member per month (demo assumption)

2. Twelve-month projection on embedded SAMPLE retention data

Month	Retention (sample)	Paying	Gross	Platform	Processing	Take-home
Total	12 months	-	-	-	-	-

The retention curve is a static sample dataset embedded in this file, not a measured cohort. Fan counts are rounded to whole members each month, so totals can differ from the unrounded product by a few cents.

3. Signed media URL: drop a file, sign path + expiry in-browser

Drop an image, audio or video file here, or click to choose one.
The bytes never leave this tab. Only an in-page hash of them is computed.

Hash + MAC self-test

Computed at page load against RFC published vectors. If a line says FAIL, do not trust any signature below.

Page key

This key is generated in this tab and never transmitted, and rotating it invalidates every URL already minted above — the same behaviour a changed signing secret produces in production, where the secret is held server-side and never reaches the browser.

How the numbers are computed

Gross revenue is arithmetic on the price, member count and platform cut you set. The live product charges through a payment provider and counts only settled subscriptions, which is the fee the card-processing line models rather than collects.
A signature is trustworthy only while the secret stays on the server. Production signs server-side against its own object storage and hands the browser a URL that the storage itself re-checks; the page key here is generated in this tab and used in this tab, which is why the secrecy boundary stays a server responsibility.
The twelve-month projection runs on the labelled sample retention curve embedded in the file. Retention, churn, conversion and traffic are not measured here.
Only the file you pick is read, and its bytes never leave the tab — the hash and the signature are computed locally.
The model covers gross, platform cut, card processing and take-home. Tax, VAT, refunds, chargebacks and per-country payout fees sit outside it.

Sample data disclosure

Embedded sample data: (a) the 12-month retention curve 100, 94, 90, 87, 85, 83, 82, 81, 80, 80, 79, 79 percent; (b) the embedded sample asset, a short ASCII string used so the media panel works before you pick a file. Everything else on this page is computed from your own slider and typed values.
