Buying credits

When you want to translate more than your plan’s monthly allowance, you can top up with additional credits at any time. Payments are processed by Stripe.

Top up flow

Section titled “Top up flow”
  1. On the panel dashboard click Buy credits.
  2. Pick a package size from the list.
  3. Click Checkout — this opens Stripe Checkout, hosted on Stripe’s domain. Card details are entered on Stripe’s servers, not ours.
  4. Complete payment.
  5. Stripe redirects you back to the panel. A Stripe webhook fires on our backend, which writes a purchases document to Firestore and bumps your ai_credits balance atomically.
  6. The new balance is visible on the dashboard within a few seconds.

What we store

Section titled “What we store”

Every completed purchase creates a document in the Firestore purchases collection with: your uid, the Stripe session ID, the Stripe payment intent, amount paid, currency, and characters purchased. We do not store card numbers, CVV, or any other cardholder data.

Receipts

Section titled “Receipts”

Stripe sends an email receipt to the address on your TranSFlator account at the moment the payment clears. That’s the official receipt for your records.

Failed payments

Section titled “Failed payments”

If a payment is declined, the Stripe webhook never fires, so no purchase is recorded and no credits are added. Nothing changes on our side. Try again with another card.

VAT / invoices for EU customers

Section titled “VAT / invoices for EU customers”

Stripe issues VAT-compliant invoices through the Customer Portal. Self-service invoice history is a planned feature on the panel; until then, email hello@tucario.com with your account email and we will send the PDFs.
