4. Subscription and Payment

Katsu is offered through monthly paid subscriptions.

Subscriptions automatically renew each month until canceled.

Payments are processed through Stripe.

Katsu does not directly store full payment-card numbers or card security codes.

By purchasing a subscription, you authorize Katsu and its payment processor to charge the applicable recurring subscription fee and applicable taxes to your selected payment method.

5. Cancellation

You may cancel your subscription at any time.

Cancellation stops future renewals but does not ordinarily terminate access immediately.

Unless Katsu suspends or terminates your account for violation of these Terms, paid access generally continues until the end of the then-current billing period.

Except where required by applicable law, payments are non-refundable.

Katsu does not provide prorated refunds or credits for:

7. Price Changes

Katsu may change subscription pricing.

We will provide at least 30 days’ advance notice of a price increase applicable to an existing subscription.

Users may cancel before the new price takes effect.

8. User Content

“User Content” means information, documents, images, text, logos, files, customer records, website material, communications, and other content that a user uploads, creates, submits, synchronizes, or stores through Katsu.

You retain ownership of your User Content.

You grant Katsu a limited, non-exclusive license to host, store, reproduce, process, transmit, modify as technically necessary, and display User Content solely as reasonably necessary to operate, maintain, secure, and provide the Service.

This license ends when the applicable content is deleted from the Service, except for temporary backup copies, legal retention requirements, or other circumstances permitted by these Terms or the Privacy Policy.
