ThreadCraft Studio (com.threadcraftstudio.app) is engineered with privacy as a foundational principle. All fabric metrics, yield costing, and density calculations are processed 100% on your mobile device.

Effective Date: September 15, 2026 App Version: 1.0.0 100% On-Device Processing

1. Overview & Commitment

Welcome to ThreadCraft Studio ("we," "our," or "us"). We respect your privacy and are committed to protecting it through strict adherence to this Privacy Policy.

This policy applies to the ThreadCraft Studio mobile application for Android (com.threadcraftstudio.app) and iOS. It describes the types of information we do not collect and the measures we take to ensure your textile business data remains completely private.

Summary for Users: ThreadCraft Studio does not require user accounts, does not collect personal data, and does not transmit your calculations to external cloud servers.

2. Data Collection & Usage

ThreadCraft Studio is designed to function as an offline utility tool. We collect zero Personal Identifiable Information (PII) from our users.

  • No Personal Data: We do not collect names, email addresses, phone numbers, IP addresses, or location coordinates.
  • No Input Data Storage: Numbers entered into Yield Costing, Batch Mass, or Density Lab (such as weight, width, price per kg) are never stored on external databases or shared with third parties.
  • No User Profiles: The app operates without registration, passwords, or social login integrations.

3. Local On-Device Computation Engine

All mathematical computations performed in ThreadCraft Studio occur exclusively in your device's local memory runtime:

Yield Costing

Cost/m = (GSM × Width × Price/kg) ÷ 1000

Executed locally in memory.

Density Lab (GSM)

GSM = Weight (g) ÷ (Length × Width)

Processed instantaneously on-device.

Batch Mass Engine

Weight (g) = GSM × Length × Width

Computed locally with zero server calls.

4. Device Permissions

ThreadCraft Studio requests only essential Android framework permissions:

Permission Name Purpose Status
android.permission.INTERNET Standard framework permission for optional network status checks. No user data transmitted. Standard

5. Third-Party Services & Analytics

ThreadCraft Studio does not integrate with third-party tracking services, analytics frameworks (such as Firebase Analytics or Mixpanel), or advertising networks. Your application usage remains completely unmonitored.

6. Children's Privacy (COPPA & GDPR Compliance)

Our application is suitable for users of all ages, including textile students, designers, and industry professionals. Because we do not collect personal data from any user, ThreadCraft Studio is fully compliant with the Children’s Online Privacy Protection Act (COPPA) and the General Data Protection Regulation (GDPR).

7. Security Standards

Because all calculation data stays entirely within your mobile device's sandbox environment, your trade secrets, pricing formulas, and fabric specs are inherently protected from network interception or cloud data breaches.

8. Updates to This Policy

We may update our Privacy Policy periodically to reflect app updates or regulatory changes. Any updates will be published on this page with an updated "Effective Date."
