Privacy
Your pasted decklist is processed to generate recommendations and is not saved to an account. Drafts and up to five recent review inputs are stored in this browser on this device. Commander-specific playtest notes also stay on this device. Clear the draft, playtest notes, and review history in the tool to remove them. Shared links include the deck and commander; only create a link for a list you want to share. Card lookups are sent to Scryfall. Hosting providers may retain routine request logs. TCGplayer links may include affiliate tracking; their privacy policy applies when you follow them. Contact tim@chaoticgreat.games with privacy requests.
Named projects, up to six versions per project, and version-specific observations are also stored on this device. Private project backups include your owned and protected inputs. Hosting infrastructure may retain routine request logs.
Usage measurement
We record actions, page paths without query strings, broad referral sources, timing, and a random session identifier that expires after 30 minutes of inactivity. A date stored on this device helps count returning sessions for up to 90 days. The server hashes session identifiers separately for each product and day. This does not identify people or link browsing between the tools. Measurement excludes decklists, card names, project names, notes, and owned cards. Do Not Track disables these new events.
Usage measurement is enabled unless Do Not Track is set.
