Privacy and your account
What IsoGrounds stores and how to contact us about your data.
Operator
IsoGrounds is operated by Kadoh Ltd. For account or privacy questions, contact us using the email above.
Account and collection
We store your sign-in email, display name, account dates, pack claims and balance, sticker holdings, album placements, swap proposals and transaction history. These support sign-in, collection storage, allocation limits and ownership checks. Other collectors see your display name and listed copies, not your email.
Sign-in and security
The site is open to browse. Collector registration and sign-in use emailed one-time codes, hashed verification records and a session cookie. Session records can include IP address and browser information. Codes expire after five minutes; collector sessions expire after 14 days unless renewed through use.
Storage and processors
The application, media and account data use Cloudflare Workers, R2 and D1. Cloudflare Email Service delivers sign-in codes. No advertising or marketing analytics is enabled by this application.
Offline copies
Saving an offline book stores selected sticker images and a read-only book on that device. It does not enable offline trading or create new copies. Use Remove offline book or sign out to clear that saved book on the device.
Your data and requests
Account, collection and exchange records are stored centrally to keep your collection available and record ownership. Email us to ask about access, correction or deletion of your account data. We may need to verify your account before acting on a request. Never send your sign-in code.
