Help for your collection
Grandfolio Support
Need help with your account, a card match or a price? Contact Chron Studios LLC.
Include the app version, your iOS version, what you tried and the wording of any error. For a card issue, include the card number and exact printing. Send screenshots only if useful, with unrelated personal information hidden. Never send a password or authentication code.
Signing in
Use the method you used to create your account. For email signup, check your inbox and spam folder for confirmation, then return to Grandfolio. Use the resend or password-reset actions in the app if needed. You can also Browse as guest to search cards without an account.
Checking a card match
Card numbers can have multiple artworks and printings. Confirm the artwork, set, rarity and edition before adding a card. Improve lighting or use manual search when a scan is uncertain. The app's estimate is not a guarantee of the physical card's identity or condition.
Understanding prices
Prices are USD estimates for the mapped exact printing and supported condition, usually raw near mint. Missing mappings or observations show Price unavailable. Stale estimates are labeled; history includes available observations, not a guaranteed price for every day. Condition, grading, language and actual sale costs can differ. Custom values and prices paid are private and separate from shared market estimates.
Privacy, friends and alerts
Collections start private; enable sharing separately for each friend. Blocking or unfriending revokes collection sharing and prevents new contact; existing chat history remains readable. Report a message, profile or avatar from its menu, or email support about abuse. Personalized JEV insights are optional in Settings; push notifications also require your permission. See the Privacy Policy for details.
Account deletion and purchases
Open Account & privacy to delete your account, and follow its confirmation and recovery steps. If you cannot access your account, contact support. Deleting the account does not cancel an App Store subscription. Manage or cancel subscriptions in iPhone Settings → your Apple Account → Subscriptions. Use Restore purchases from Grandfolio's Pro settings on the original Grandfolio account. Apple handles App Store billing and refund requests.
Optional diagnostics
If support requests diagnostics, use Settings → Diagnostics → Prepare diagnostics → Share diagnostics. Review the export before sending it. This is optional; it is not sent automatically.
