2.1 Information You Provide
• Garment photos you capture or select from your photo library to scan and generate flip ideas
• Bookmarked flips and scan history that you save to your workbench
• Profile details you enter during onboarding: skill level, interests, whether you have a sewing machine, and whether you're open to no-sew options
• Account details if you choose to sign in: email, display name, and sign-in identifiers from Apple
• Support requests and feedback you send us, including any information you include in the message2.2 Automatically Collected Information
• Device and app information: device type, operating system, app version, language settings
• Usage and analytics: screens viewed, features used, scan counts, session events
• Crash and error diagnostics used to fix bugs
• Approximate location inferred from IP address (not precise GPS)
• Subscription state returned by our billing provider (active, trial, expired) to unlock Pro features2.3 AI-Assisted Flip Generation
When you submit a garment photo, the App uploads it to our backend so an AI model can analyze it and return three flip ideas, plus a step-by-step plan when you tap into one. We may use Anthropic, OpenAI, or other models routed through OpenRouter, and the provider or model may change for testing, availability, or performance.
The routing or model provider may retain or log inputs and outputs or use them to improve services or models under its own terms and configuration. BBF does not guarantee zero data retention or that a provider will never use submitted data for training.
Please avoid submitting photos that contain unnecessary sensitive personal information (such as faces, license plates, or documents in the background).2.4 Cait's Tutorial Content
The tutorial videos that play inside the App are content authored and owned by Cait Trantham (Cait Conquers), threaded in from her public TikTok library and any custom clips she records for the App. BBF does not claim ownership of Cait's videos. We do not collect or upload videos you film of yourself — V1 has no user video upload.2.5 Permissions
Camera access lets you photograph garments inside the App. Photo library access lets you select existing photos. Microphone access is requested by iOS for video recording but the App does not record audio in V1. Local notifications are optional and used only to nudge you back to a saved flip. You can revoke any permission at any time in your device settings.Sources of information: We receive information from you, automatically from your device and use of the App, and from any sign-in provider, marketplace, or other service you choose to connect, including the app store. The categories above describe what we collected during the preceding 12 months; we do not collect a category unless the App uses the related feature.3. How We Use Your Information

Rethread Is a Creative Tool, Not a Sewing Authority
Rethread is an AI-assisted creative tool. It is not a substitute for a qualified sewing instructor, pattern-maker, or your own judgment about what's safe to cut. Flip ideas and step-by-step plans are generated by artificial intelligence and may suggest moves that don't fit your specific fabric, garment construction, or skill level. Always inspect your garment, test on a scrap when in doubt, and stop if something isn't working. Cait's tutorial videos are her own creative work; following them is at your own risk and responsibility.12. Updates to This Policy
We may update this policy as the App or law changes. The Last Updated date shows when it was revised. If a change materially affects how we use personal information, we will provide notice in the App, by email when available, or by another reasonable method before the change takes effect where required.
