Privacy policy

Last updated: November 13, 2026

Spinecatch helps you keep track of books you find in short videos. This policy explains what the app collects, why, and the choices you have.

What we collect

Account: if you sign in, we receive your sign-in ID and the email address your sign-in provider shares (with Sign in with Apple you can hide your real email).
Your shelves: book titles, authors and shelf status (To Read, Reading, Read, Did Not Finish) that you save.
Things you share to the app: the link and caption of a video you share, used only to find the books in it. The link is removed from our records once the import finishes.
Files you import: a Kindle or reading-list file you choose. We read the book details in it and do not keep the file itself.

No ads, and no advertising or cross-app tracking.
We don't sell or rent your data.
We don't read your TikTok, Instagram or Amazon accounts. We only see what you choose to share or import.

Your data is stored with our database provider, Supabase, in the United States. Access rules limit each account to its own books and imports.

Some books link to Amazon or Kindle. Opening those links takes you to that service, and its own privacy policy applies there.

We keep your shelves while your account exists. To delete your account and everything in it, email [email protected]. We delete it within 30 days.

Spinecatch isn't directed at children under 13, and we don't knowingly collect their data.

If this policy changes, we'll update the date at the top of this page.
