Privacy
Last updated 2026-04-20
Cube Doctor is a free analysis tool. We collect the minimum needed to run it and keep it from being abused. This page is a plain-English summary; it is the policy, not a supplement to one.
What we collect when you submit a cube
- The CubeCobra URL, my.cardivore.app URL, or raw card list you paste. We fetch / store the card list so the simulator can draft it.
- Your IP address, hashed with a rotating salt, to enforce one free report per 24 hours and to skip the rate limit for whitelisted devices. We do not store your raw IP.
- An hCaptcha challenge result, verified server-side. hCaptcha is a third-party service; their privacy policy applies to the challenge itself.
What we publish
-
The generated report lives at
cube.cardivore.app/r/<slug>. The slug is public; anyone with the URL can read the report and share it. - Reports include the cube name you provided and the card list's derived analysis. They do not include your IP, your email, or any account identifier.
What we do not do
- We do not set advertising or analytics tracking cookies.
- We do not sell, share, or rent your information to third parties.
- We do not build a profile of you or your cubes beyond the report itself.
- We do not require an account or email to use Cube Doctor.
Affiliate links
Cards recommended in a report link to TCGplayer through our affiliate ID. If you buy a card after clicking one, we earn a small fee โ TCGplayer tells us the order happened but not who placed it. This funds keeping the tool free.
Retention
- Submitted cube data and generated reports persist indefinitely unless you email us to take them down.
- Rate-limit IP hashes expire automatically after 24 hours.
- Server-side logs (errors, costs) roll over every 30 days.
Removing your data
Email hello@cardivore.app with the report URL you want taken down. We'll delete it within a few days.
Changes
We'll bump the "Last updated" date at the top of this page whenever we change it. There is no mailing list โ if you care, bookmark it.
