Terms of Use (EULA)

1. Acceptance & License Grant

By downloading, installing, or using Chalkline: Estimate & Invoice (com.chalklineapp.app, "Chalkline" or the "App"), you agree to these Terms of Use ("Terms"). Subject to your compliance with these Terms, we grant you a personal or internal-business, non-exclusive, non-transferable, revocable license to install and use Chalkline on Apple iOS/iPadOS or Android devices that you own or control.

If you download Chalkline from the Apple App Store, you acknowledge that these Terms are concluded between you and Chalkline only (not Apple Inc.), that Apple has no obligation to furnish maintenance or support services for the App, and that Apple and its subsidiaries are third-party beneficiaries of these Terms with the right to enforce them in accordance with Apple's Standard Licensed Application End User License Agreement.

2. Free Tier, Subscriptions & 7-Day Pass Billing Terms

2.1 Free Forever Tier & Fair Revision Allowance

Without purchasing a subscription or creating an account, Chalkline provides: (a) unlimited access to all six manual L × W trade calculators; (b) one (1) saved satellite property takeoff project; and (c) one (1) unwatermarked customer PDF proposal or invoice, including up to three (3) free pricing or scope revisions for that same customer and jobsite address. Once your first customer PDF is exported, client identity and site geometry are locked on that record so free single-quote allowances cannot be overwritten across unrelated jobs.

2.2 Chalkline Solo Pro (Auto-Renewable Subscriptions)

• Plans Available: Solo Pro Annual (chalkline_solo_pro_annual, $99.99 USD/year baseline or localized store price) and Solo Pro Monthly (chalkline_solo_pro_monthly, $19.99 USD/month baseline or localized store price). Exact prices in your local currency are provided directly by the Apple App Store or Google Play Store on the purchase screen.
• Introductory Free Trial: Eligible first-time subscribers to Solo Pro Annual may receive a 7-day free trial as indicated by Apple StoreKit or Google Play Billing at checkout. If you already used an introductory offer, standard subscription billing applies immediately upon confirmation. Any unused portion of a free trial period is forfeited when purchasing a subscription where applicable.
• Auto-Renewal & Cancellation: Payment is charged to your Apple ID or Google Play account at confirmation of purchase (or at the conclusion of an eligible free trial unless canceled at least 24 hours before the trial period ends). Subscriptions automatically renew for the same term unless auto-renew is turned off at least 24 hours before the end of the current billing period. Your account will be charged for renewal within 24 hours prior to the end of the current period.
• How to Manage or Cancel: You can manage or cancel auto-renewal at any time in iOS Settings > [Your Name] > Subscriptions (apps.apple.com/account/subscriptions) or Google Play Store > Profile > Payments & subscriptions > Subscriptions (play.google.com/store/account/subscriptions). Uninstalling the App does not automatically cancel an active store subscription. Refunds are handled directly by Apple or Google under their respective store refund policies.

2.3 7-Day Single Project Pass (Non-Renewing)

7-Day Single Project Pass (chalkline_project_pass_7d, $9.99 USD baseline or localized store price; offered as an iOS Non-Renewing Subscription and a Google Play 7-Day Prepaid Plan) unlocks Solo Pro features for a fixed period of seven (7) calendar days (168 hours) from purchase. It does not auto-renew and expires automatically after 7 days.

2.4 Permanent Zero Data Hostage Guarantee

If your Solo Pro subscription or 7-Day Pass expires or is canceled, all proposals, invoices, and PDFs you previously saved on your device remain permanently viewable and re-shareable offline in Read-Only Archive mode. Creating new satellite projects (2nd+), generating new customer quotes/invoices (2nd+), duplicating quotes, or editing locked quotes requires an active Solo Pro entitlement.

3. Field Measurement, Material Takeoff & Engineering Disclaimer

IMPORTANT — VERIFY ON SITE BEFORE ORDERING MATERIALS: Chalkline is an estimating and proposal productivity tool, not a licensed land survey, structural engineering specification, or guaranteed material bill.

• Satellite & Map Imagery Limitations: Aerial and satellite imagery provided via Apple Maps or Google Maps may be outdated or affected by tree canopy, shadows, roof eaves, terrain relief, camera off-nadir tilt, or projection tolerances. Always verify critical property lines, dimensions, and grades on site with calibrated physical tape, measuring wheel, or laser tools (using Chalkline's Edge Override feature where needed).
• Material Density, Swell, Compaction & Short-Load Formulas: Ready-mix concrete volumes, bag yields, aggregate loose-to-compacted tonnage ratios, asphalt densities, fence post counts, mulch/topsoil settling, and rock salt application rates vary by local supplier, moisture content, subgrade depth variance, form deflection, and regional building codes. Confirm final order quantities and minimum truckload thresholds directly with your batch plant or material supplier prior to dispatch.

4. Invoices, Statutory Tax Labels, Signatures & Zero-Interest Schedules

• Tax & Trade Registration Compliance: You are solely responsible for the accuracy of tax rates, contractor license numbers, and statutory tax identifiers you enter (including US Sales Tax, Canadian GST/HST/QST, UK VAT & CIS notes, and Australian ABN / GST). Do not issue documents labeled TAX INVOICE or VAT INVOICE unless you hold active statutory tax registration in the applicable jurisdiction.
• On-Screen Client Acceptance Signatures: Chalkline captures finger-drawn signature strokes, printed name, timestamp, and a content hash over quote/invoice terms; any subsequent edit to scope, pricing, or client details voids the prior signature. You are responsible for determining whether an on-screen signature satisfies contract-formation, home-improvement disclosure, and statutory cooling-off requirements in your state, province, or country.
• 0%-Interest Milestone Schedules Only: Chalkline generates flat, 0%-interest deposit and stage payment schedules only. Chalkline is not a lender, credit broker, financial institution, or payment processor, and never adds interest, APR financing, or compounding late fees.

5. Acceptable Use & Map Provider Restrictions

You agree not to reverse engineer, scrape, bulk-download, pre-fetch, or redistribute satellite map tiles or imagery in violation of the Apple Maps Terms of Use or the Google Maps Platform Terms of Service (including Google Maps Terms §3.2.3).

6. Disclaimer of Warranties & Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, CHALKLINE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, ACCURACY, OR FITNESS FOR A PARTICULAR PURPOSE. WE SHALL NOT BE LIABLE FOR ANY MATERIAL OVER-ORDERING, MATERIAL SHORTAGES, READY-MIX SHORT-LOAD FEES, BIDDING UNDERESTIMATES, CONTRACT DISPUTES, TAX PENALTIES, DATA LOSS CAUSED BY DEVICE FAILURE OR UNINSTALLATION, OR INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES. IN ALL CASES, OUR AGGREGATE LIABILITY SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR CHALKLINE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM OR (B) TWENTY-FIVE US DOLLARS ($25.00 USD). SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME EXCLUSIONS ABOVE MAY NOT APPLY TO YOU.
