## Epic 15 — Monetization & Onboarding
**Goal:** Establish sustainable revenue with a generous free tier and frictionless onboarding.

### Story 15.1: Free Tier

As a CalcPad user on the free tier,
I want access to core calculation features without payment,
So that I can evaluate CalcPad fully and use it for everyday calculations at no cost.

**Acceptance Criteria:**

**Given** a user is on the free tier
**When** they use the application
**Then** they can perform unlimited calculations with no daily or monthly cap
**And** all built-in units and currency conversions are available
**And** they can create and manage up to 10 sheets

**Given** a free-tier user attempts to create an 11th sheet
**When** the sheet creation action is triggered
**Then** a non-intrusive prompt explains the 10-sheet limit
**And** the prompt offers an upgrade path to Pro
**And** existing sheets remain fully accessible and editable

**Given** a free-tier user
**When** they access appearance settings
**Then** the basic set of built-in themes is available for selection
**And** Pro-only themes are visible but marked with a Pro badge and are not selectable

**Given** a free-tier user
**When** they export a sheet
**Then** export to plain text and Markdown formats is available
**And** PDF and HTML export options are visible but marked as Pro features

**Given** a free-tier user with no internet connection
**When** they use CalcPad offline
**Then** all free-tier features work fully offline including calculations, unit conversions, and local sheet storage
