Subprocessors

Last updated: July 22, 2026

This page lists every third-party service provider Cratewise shares data with, what they receive, and why. It's the same list named in our Privacy Policy, kept here as its own page so it stays current without a full policy edit every time a provider changes. We don't sell your data — everything below is a provider that helps us run the service, and only for the purpose listed.

Providers that receive your personal data:

Anthropic (Claude). Cover images and text you submit, for AI-based record identification and generating artist/album descriptions.

Google. Your email, name, and Google account ID, for sign-in only, if you use "Sign in with Google."

Paddle. Billing details, subscription status, and transaction records. Paddle is the merchant of record for your purchase and handles billing on our behalf.

Resend. Your email address, for sending invite, waitlist, and product-update emails.

Cloudflare (R2). Cover art images you upload, for file storage.

Railway (Postgres). Your account and collection data. Railway hosts our primary database.

Sentry. Error reports, which include your account ID. We tag errors with your account ID deliberately, so we can investigate account-specific issues — not incidentally.

Providers that only receive catalog lookups, not your personal data:

Discogs and Apple Music / iTunes. Search terms (artist, title, catalog number), to look up release, album, and track metadata — never your personal data.

MusicBrainz. Nothing — we use MusicBrainz data to build our own offline catalog database. We don't send it any of your data or search queries.

International data transfers. Some of the providers above are located, or process data, outside your country — including in the United States. Where we or our providers transfer personal data internationally, we rely on appropriate safeguards, such as Standard Contractual Clauses approved by the European Commission, to protect your data to the same standard required under GDPR.
