CostCurve Product Schedule

Product-specific Android schedule. This schedule supplements the separate Terms and Privacy Policy for package com.ryantinklepaugh.costcurve.

Product purpose

CostCurve is a receipt-backed ownership-cost ledger that pairs purchase evidence with item lifecycle, dated use events, target cost per use, purchase-pause decisions, resale outcomes, and a user-directed portable sync archive and evidence export.

Current data and permission boundary

app-private item names, categories, currency, purchase price, purchase date, tax, fees, target cost per use, lifecycle and resale fields, notes, and timestamps
dated use events and notes, purchase-pause decisions, receipt images, on-device OCR text and confidence, and user corrections
user-directed portable sync archives plus locally generated CSV and PDF evidence exports
purchase entitlement and legal-choice evidence

Camera or photo access is requested only when you deliberately capture or select receipt evidence. Google ML Kit recognizes text on the device; receipt images, recognized text, and ledger records are not uploaded to Uncommon Weather or Supabase. Portable cross-device sync is a user-created archive saved or opened through Android’s document picker; there is no automatic product-data cloud. Exports leave only through a user-directed save or share action.

Required safety boundary

CostCurve is recordkeeping and arithmetic support, not financial, accounting, tax, legal, valuation, investment, or purchasing advice. OCR can be wrong; verify the receipt, currency, tax, fees, dates, usage, resale, and assumptions. CostCurve does not fetch foreign-exchange rates or combine currencies; cost-per-use and trends are estimates, not market value.

Limited mode

After a decline or withdrawal, the following remain available:

read-only ledger, receipt, history, lifecycle, and purchase-decision records
existing local PDF and CSV export, portable backup, and deletion controls
legal, support, purchase-management, and purchase-restoration controls

The following remain unavailable until the current documents are affirmatively accepted:

new OCR, camera capture, receipt import, or archive merge
new or edited items, use events, decisions, or lifecycle changes
new purchases

Legal choices and verification

A decline or withdrawal takes effect locally at once and remains limited without recurring prompts. A current affirmative choice unlocks ordinary app access after it is durably stored on the device; signed-receipt delivery may retry in the background. Android proof is recorded separately from iOS proof. A service outage does not silently convert a decline into acceptance or relabel an iOS receipt as Android.
