Optionomics has a free tier and paid plans. The Subscription page shows which plan you are on and opens Stripe's billing portal, where you change plan, update a payment method or cancel.

Where it lives

• User menu (top right) → Subscription.
• Direct route: /subscription.

What you can do

• Change plan — in the billing portal. Changes take effect immediately.
• Switch billing period — monthly ↔ annual; annual is discounted.
• Update payment method — Stripe handles all card / bank details. We never see card numbers.
• Cancel — Cancel subscription on the Subscription page. Access continues until the end of the period you have paid for.

Receipts & invoices

• Every successful charge produces a Stripe receipt by email. Past invoices are in the billing portal (Open billing portal).

What happens after cancel

• Access continues until the end of the period.
• Your data sticks around — alerts, watchlist, saved views — so re-subscribing later picks up exactly where you left off.

Tips

• Subscribed through the iOS app? Billing is managed by the App Store, not here.
• Run into a billing issue? The Help → Contact link sends to a human, not a queue.
