Technical Debt Radar processes payments through Stripe for credit and debit cards, and PayPal as an alternative payment option. All payment data is handled by Stripe and PayPal directly --- Radar never stores card numbers or bank details on its servers.

Supported Methods

Method	Provider	Details
Credit cards	Stripe	Visa, Mastercard, American Express, Discover, JCB, Diners Club, UnionPay
Debit cards	Stripe	All major debit networks supported through Stripe
PayPal	PayPal	PayPal account balance, linked bank account, or PayPal Credit

Adding a Payment Method

Credit or Debit Card

1. Go to Settings then Billing then Payment Methods
2. Click Add Card
3. Enter your card number, expiration date, CVC, and billing zip/postal code
4. Click Save
5. The card is verified with a $0 authorization (no charge) and added to your account

PayPal

1. Go to Settings then Billing then Payment Methods
2. Click Add PayPal
3. You are redirected to PayPal to authorize recurring payments
4. Approve the billing agreement in PayPal

Default Payment Method

Your default payment method is charged for all subscription renewals and credit pack purchases. The first payment method you add becomes the default.

To change your default:

1. Go to Settings then Billing then Payment Methods
2. Find the payment method you want to use
3. Click Set as Default

Your next charge will use the new default method.

Removing a Payment Method

1. Go to Settings then Billing then Payment Methods
2. Click the remove icon next to the payment method
3. Confirm removal

Note: You cannot remove your default payment method while you have an active paid subscription. Either add a new default method first or downgrade to the Free plan.

Updating Card Details

If your card is reissued (new number or expiration date):

1. Add the new card as a new payment method
2. Set the new card as default
3. Remove the old card

Stripe supports automatic card updates for many issuers. If your bank participates in Stripe's card updater program, your card details may be updated automatically when reissued.

Payment Failures

When a payment fails, Radar follows this retry schedule:

Attempt	Timing	Action
1st attempt	Billing date	Charge attempted, email sent on failure
2nd attempt	3 days later	Retry charge, reminder email
3rd attempt	7 days later	Final retry, warning email
Account pause	10 days after billing date	Paid features disabled, deterministic scanning continues

What Happens During a Payment Failure

• Your subscription remains active during the retry period
• All features continue working for 10 days
• You receive email notifications at each retry attempt
• After the 3rd failed attempt (day 10), paid features are paused:
  • AI features are disabled
  • PR gate checks fall back to deterministic only
  • Dashboard access is read-only
  • CLI scanning continues (always free)

Resolving a Failed Payment

1. Go to Settings then Billing then Payment Methods
2. Update your payment method or add a new one
3. Click Retry Payment
4. On success, all features are restored immediately

Currency

All prices are in USD. Stripe handles currency conversion for international cards at the exchange rate set by your card issuer.

Security

• Radar is PCI DSS compliant through Stripe --- card data never touches Radar's servers
• All payment pages use TLS 1.3 encryption
• Stripe's fraud detection (Radar for Fraud) is enabled on all transactions
• PayPal transactions are covered by PayPal's buyer and seller protections

Receipts

A receipt is emailed automatically after every successful charge. Receipts are also available in the dashboard under Invoices.
