Billing

Refund Policy

This Refund Policy explains how Arche subscriptions are billed, how to cancel and when a refund is issued.

  • Free plan, not a trial. The Free plan needs no payment details and does not expire, so the service can be evaluated before any charge.
  • Monthly or annual billing. Paid plans are billed in advance for the term selected at checkout and renew until canceled.
  • Limited refund circumstances. Refunds are issued for duplicate payments, billing errors or where consumer protection law requires one.

By purchasing a subscription to the Arche API and MCP server, you agree to this Refund Policy.

Evaluating before you buy

The Free plan requires no payment details and does not expire. It grants the same point-in-time retrieval, statement versioning and lineage as the paid plans across a smaller universe of companies, so the service can be evaluated in full before any charge is made.

Subscription billing

Paid plans are billed in advance for the term selected at checkout — monthly or annual — at the price shown on the pricing page. Subscriptions renew automatically for the same term until canceled.

Cancellation

You can cancel at any time from the Billing page in the developer portal, or by emailing hello@protos.fi. Canceling stops the next renewal. Access continues until the end of the period you have already paid for, and the unused remainder of that period is not refunded.

Refunds

Because Arche provides immediate access to proprietary financial data infrastructure, charges are final once a billing period has begun. Refunds are issued in the following circumstances:

  • Duplicate payments.
  • Billing errors, including a charge at the wrong amount or for a plan that was not purchased.
  • Where a refund is required by consumer protection or other law applicable in your jurisdiction. Paddle.com Market Ltd, as merchant of record, administers these.

Other requests are reviewed case by case at our discretion. Email hello@protos.fi with the invoice number and we will respond within five business days.

How refunds are paid

Approved refunds are returned to the original payment method by Paddle.com Market Ltd. The time to appear on a statement depends on your bank, and is typically five to ten business days.
