Privacy policy
What Mana Value knows about you: almost nothing.
There are no accounts, no sign-in and no cookies. Here is everything that happens when you visit manavalue.org or use the Cardmarket Tools.
Last updated
No accounts
Nothing to sign up for, so there is no profile, email or password to hold.
No cookies
The site sets none. Its analytics count visits without cookies.
Nothing sold
No data is sold, shared for advertising, or used to profile you.
Tools collect nothing
The extension and userscript keep everything in your browser.
01
The website
Analytics
Visits are counted anonymously with Cloudflare Web Analytics, which uses no cookies and doesn't follow you across other sites.
Card images
Card images are shown from Scryfall, which isn't told which page you're viewing.
Affiliate links
Some links to TCGplayer are affiliate links: Mana Value may earn a commission if you buy something, and TCGplayer may set its own cookies when you follow one.
If you write to support@manavalue.org, your message and address are used only to reply.
02
Cardmarket Tools
The Firefox and Chrome extension, and the userscript
The tools collect no personal data and send nothing about you anywhere. They run only on Cardmarket's Offers, Bulk Listing and Wants pages, and contain no analytics.
Price data
They download public price lists from manavalue.org. Nothing about you is sent with them.
Your Cardmarket account
They only act on your account when you press one of their buttons, such as adding to cart or repricing your stock.
Your CSV and wants lists
A ManaBox CSV you load stays in your browser and is never uploaded. Exporting a wants list only copies it to your clipboard.
03
Stored in your browser
Kept on your device, never sent to Mana Value. Clearing your site data removes all of it.
| On | What | How long |
|---|---|---|

| cardmarket.com | Tool settings and which panels are collapsed | Until you clear it |
| cardmarket.com | Saved price data, so pages load faster | Refreshed every 24 hours |

04
Other sites
Links to Cardmarket, TCGplayer, X and Instagram are ordinary links. Once you follow one, that site's own privacy policy applies.
