Support & Contact

Write to frontlinehi808@yahoo.com from the email address on your account. That lets us match your message to the right account without asking for a password — which we will never ask for.

To get help faster, include: what you were doing, what you expected, what happened, and your device (for example "iPhone, Safari").

• Can't sign in with Google? Open the app in your normal browser rather than inside another app's built-in browser, then try again. Email and password sign-in always works as a fallback.
• Forgot your password? Use "Forgot password?" on the sign-in screen and follow the emailed link.
• Scanner won't identify a card? Fill the frame, avoid glare, and keep the card name and set number readable. If it still fails, use "Add manually instead" — the Vault accepts typed cards.
• Numbers look wrong? Kevin only shows what you entered. Open the card in the Vault and check the paid price, shipping, fees and current value.
• Want a tool back to a clean state? Tool Center has a safe reset per tool. It clears only that tool's temporary browser state and never deletes saved rows or signs you out.

Signed in, go to Profile → Your data to download a JSON export of everything the app stores for your account, or to permanently delete your account. Deletion cannot be undone, so export first.

If the in-app controls don't work for you, email frontlinehi808@yahoo.com from your account address and we'll handle it manually.

Beta feedback is genuinely useful. Send bugs and feature ideas to frontlinehi808@yahoo.com. Screenshots help. If something looks like a security problem, please say so in the subject line and we will prioritise it.

• Value your cards for you, or confirm a price is correct — the app has no live market feed.
• Give financial, investment, tax or appraisal advice.
• Broker, ship, insure or refund any trade or sale. The Marketplace is a listing board with no checkout, payment, shipping or messaging.
• Recover a deleted account. Deletion is permanent.

Requests that affect the whole service — closing the owner account, transferring ownership, or a full-service shutdown — must be arranged deliberately by email at frontlinehi808@yahoo.com. They are not available as a self-service button.
