Terms

Effective 13 October 2026.

These terms are between you and Xanthous Tech LLC, a Delaware (United States) company that operates SubPorter. Contact us at support@subporter.com. By using SubPorter, you agree to them.

The service

SubPorter helps you plan and carry out the Stripe Billing portion of an account-to-account migration. It scans Stripe objects, prepares the migration plan, records decisions and approvals, applies the writes you authorize, and produces migration records.

SubPorter does not move your application database, entitlements, webhooks, tax configuration, or other systems outside the documented Stripe Billing workflow. You remain responsible for those systems and for deciding when a migration is ready to proceed.

Your responsibilities

You must have authority to access every Stripe account you connect and to authorize each action you approve. Provide restricted keys with only the documented permissions. Keep account access secure, review the plan and the flagged subscriptions, coordinate with the other account owner, and verify your application before the cancel step.

Do not use SubPorter unlawfully, interfere with the service, or attempt to access another customer's project.

Pricing and payment

Planning and sandbox migrations are free. Small Exit costs $99 for migrations with up to 100 active subscriptions. Standard costs $199 for more than 100. Both are one-time prices with no MRR-based pricing. Payment is charged before the first write to the destination account.

Refunds

The fee is charged before the first write to the destination account. If no write step has run, ask us and we refund in full. Once the first write has run, the fee is not refundable, because Stripe objects now exist that both owners depend on. If a defect in SubPorter stops your migration, we refund in full.

Stripe access and records

Stripe restricted keys are encrypted and held only for the migration. They are deleted 30 days after project completion or after 30 days of inactivity for an incomplete project. SubPorter keeps project summaries, migration records, approvals, payment records, and audit events.

Availability and risk

Stripe migrations can depend on account configuration, Stripe API behavior, data quality, and decisions made by both account owners. SubPorter shows checks and flagged subscriptions, but you are responsible for reviewing them and approving the writes. The service is provided as available, to the extent permitted by law.

Governing law

These terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-law rules. Courts located in Delaware will have jurisdiction, unless applicable law requires otherwise.

Changes

We may update these terms as the service changes. The effective date above shows the latest revision. Continued use after an update means you accept the revised terms.
