We collect your email address when you create an account. We collect the measurements you enter for your client profiles. We collect the garment photos you upload to generate patterns.
Your email is used to send you your downloaded patterns and account notifications. Your measurements are stored to save you time on future projects. Your photos are sent to OpenAI's GPT-4o service to detect the garment style — this is how the style detection works. Photos are not stored by OpenAI after processing.
We do not sell your data. We do not share your client measurements with anyone. We do not use your data for advertising.
Your data is stored securely using Supabase. Payment processing is handled by Stripe — we never see or store your card details.
Garment photos you upload are deleted within 24 hours of upload — both the original and the processed copy are removed from storage automatically. Your patterns, measurements and account details are kept until you delete them. When you delete your account we remove your account and any photos still held for you.
