Privacy Policy & Copyright

Copyright & Trademarks
Comic cover images, character names, publisher logos, and other artwork displayed on this site remain the property of their respective publishers, creators, and rights holders. Mild Mannered Collector does not claim ownership of, and is not affiliated with or endorsed by, any comic publisher whose work appears here. Cover images and catalog metadata are sourced from the Grand Comics Database™ and from images uploaded by users to represent their own physical copies. This content is shown solely for identification, cataloging, and informational purposes.
What We Collect
Account information (email address and authentication session) is managed by Supabase Auth. The comic collection data you enter — issues, notes, condition/grade, purchase details — and any cover or scan images you upload are stored so the app can show them back to you. Scan images used for comic identification are processed in memory to identify the comic. When the app cannot identify a comic, or identifies it with low confidence, that scan image is kept for up to 30 days so we can diagnose the failure and improve identification — it is accessible only to site staff, is never shared, and is deleted automatically. A record of each scan (which providers ran, the result, and what you did next) is also kept to measure and improve accuracy; it does not include your IP address in readable form.
Local Storage On Your Device
The app stores your sign-in session locally (via browser storage on web, or secure device storage on Android/iOS/Windows) so you stay signed in between visits. This is used only to keep you logged in — not for tracking or advertising.
Third-Party Services
This site is built on: Supabase (authentication), Cloudflare (hosting, content delivery, and image storage), Fly.io (backend hosting), and Neon (database hosting). Comic pricing and listing data shown on issue pages is retrieved from eBay. Marketplace payments happen entirely off-platform via PayPal.me links — this app never processes or stores payment information.
Affiliate Links
Mild Mannered Collector participates in the eBay Partner Network, an affiliate advertising program. When the site links to an eBay listing (for example in the “eBay Listings” section of an issue page) and you click through and make a purchase, Mild Mannered Collector may earn a commission from eBay at no additional cost to you. These links carry an affiliate tracking code but do not identify you personally to us, and we are not sent any details of what you buy. Using them is entirely optional.
