What to include in your email.
- The email address used at checkout, if this is a customer question.
- Your company and the page or product you are asking about.
- What you expected to happen and what happened instead.
Please do not send full card numbers, passwords, or health information. Stripe handles payment-card details.
02 · Billing and access
Stripe handles the payment layer.
Stripe handles receipts, subscription status, payment-method changes, and the customer billing portal. If you paid and cannot reach your customer record, email hello@formulasignal.com or use Customer access.
To cancel, email before your next billing date or use the billing portal available from your customer account.
03 · Corrections
Found something that may be wrong?
Email the page URL, the source you are relying on, and what you think is wrong. Material corrections are investigated and displayed transparently.
