Frequently Asked Questions

How do I upgrade to CardChart Pro?

Open the app, go to the Account tab, and tap Upgrade to Pro. On iPhone, the subscription is handled securely through your Apple ID. Pro unlocks advanced indicators (RSI, MACD, Fibonacci, VWAP, TWAP, Kalman Filter), CSV export, and more.

How do I cancel my subscription?

On iPhone, subscriptions are managed by Apple. Open Settings → [your name] → Subscriptions, select CardChart, and tap Cancel. You'll keep Pro access until the end of your current billing period. You can also reach this from Account → Manage Subscription in the app.

I paid but Pro features are still locked.

Go to Account → Restore Purchases in the app — this re-checks your subscription with Apple and unlocks Pro. If it still doesn't work, email us and we'll sort it out.

Why is price data missing or out of date for a card?

CardChart's charts are built from real eBay sold listings and price history. Cards that sell infrequently (rare vintage, low-population graded slabs, brand-new sets) may have sparse data. Popular modern cards in Raw NM condition have the most reliable history.

Is the price data financial advice?

No. CardChart is an informational tool for collectors. Technical indicators describe historical price behavior — they are not predictions or financial advice. Always do your own research before buying or selling.

How do I delete my account?

In the app, go to Account → Delete Account. This permanently removes your account, watchlist, and portfolio. If you need help, email us.

How is my data protected?

Your watchlist and portfolio are stored securely and tied to your account. We never sell your data. See our Privacy Policy for full details.
