Official Privacy Document for InfillQuote: 3D Print Calc • Last updated: October 2026

Local-First Commitment & Optional Cloud Sync

InfillQuote operates under a strict Privacy by Design and Local-First paradigm. Your printer fleets, materials catalog, hourly rates, profit margins, and customer quotation records are stored solely in your device's private local SQLite database. For users who choose to connect multiple devices and access the Web Companion, we provide encrypted Cloud Sync via secure authentication, with zero data selling and full deletion control at any time.

1. Privacy by Design & Local-First Architecture

InfillQuote: 3D Print Calc was engineered from the ground up to guarantee full operational privacy for digital fabrication workshops, hardware engineers, and rapid prototyping studios. All computational models, slicer parameter histories, machine depreciation schedules, and client quotes remain exclusively on your physical device. No remote telemetry captures your proprietary pricing formulas.

2. Data Collection and Usage

  • Personal Information & Optional Cloud Sync: We do not require account registration or identity disclosure for offline/local calculations. If you voluntarily choose to enable cross-device synchronization (Cloud Sync) or access the Web Companion (app.infillquote.com), we collect your email address and authentication identifier via secure sign-in providers (Google Sign-In / OAuth and Supabase Auth). Email addresses are used exclusively for account authentication, session management, and encrypted synchronization of your workshop printers, materials, and quotations. We never sell personal data or email addresses to advertisers, data brokers, or marketing networks.
  • Device Permissions: Standard platform permissions (such as storage or share dialogs) are utilized exclusively when you explicitly export PDF proposals, work orders, or JSON database backups.
  • Zero Advertising SDKs: InfillQuote contains no third-party banner networks, behavioral trackers, or data broker integrations.

3. In-App Purchases & Subscription Entitlements (PRO Tier)

InfillQuote offers optional PRO subscription plans (Monthly and Annual auto-renewable subscriptions) and a Non-Consumable Lifetime license to unlock advanced studio capabilities (unlimited spools, multi-material AMS/MMU purge calculations, and custom logo PDF exports).

  • Payment Processing: Transactions are handled directly by Google Play Billing (Android) and Apple App Store In-App Purchases (iOS). We never receive, process, or store your credit card or financial account numbers.
  • Subscription Management: Subscriptions renew automatically unless canceled at least 24 hours prior to the close of the current billing cycle via your Google Play or Apple ID account settings.
  • Receipt Validation: We utilize RevenueCat for anonymous digital receipt validation. Only anonymous cryptographic tokens are processed to verify entitlement status.

5. Disclaimer & System Requirements

InfillQuote is a technical decision-support and cost-estimation utility. Physical printing tolerances, actual material consumption, machine wear, and thermal environmental variables remain under the direct control and responsibility of the shop operator. Standard Apple End User License Agreement (EULA) applies for iOS downloads: Apple Standard EULA.
