Privacy policy

Last updated 2026-10-07

The short version

• Free tools (bubble letters, name pages, instant photo sketch) run in your browser. Your text and photos are not uploaded.
• AI pages: your photo is sent once to our image provider to draw the page, then discarded. We never store uploaded photos and never use them to train models.
• Finished AI pages, pages you save and coloring books are kept for 30 days in your private “My creations”, then deleted automatically.
• We don’t sell personal data and we don’t run ads on our tool pages.

What we collect

• Account: when you sign in with Google we receive your email address. We store it encrypted, plus a keyed hash to find your account.
• Purchases: payments are handled by Stripe; we keep the pack, amount and status, never your card details.
• Usage: privacy-friendly analytics (Google Analytics 4) with page paths and coarse events such as “downloaded a PDF”. We never send photos, names you type, or file contents to analytics.
• Security: a session cookie and short-lived rate-limit counters.

Processors

Vercel (hosting), Supabase (database and private file storage), Stripe (payments), Google (sign-in, analytics) and our AI image provider (OpenRouter and the model vendor it routes to), which receives a photo or text prompt only when you start an AI page.

Children

Linecraft is a tool for parents, teachers and other adults and is not directed to children under 13. Please don’t let children create accounts. If you believe a child has given us personal information, contact us and we’ll delete it.

Your choices

You can delete any creation from “My creations” at any time. To delete your account and email address, write to zhanggongqing1314008@gmail.com.
