What SubPorter stores, why it stores it, and how Stripe access keys are handled.

Effective 13 October 2026.

SubPorter is operated by Xanthous Tech LLC, a Delaware (United States) company. Contact us at support@subporter.com.

Information we handle

We store the account information needed for sign-in, including your name, email address, verification records, and basic session records such as IP address and user agent.

For a migration, we store project names, owner roles, Stripe account identifiers, scan and plan summaries, decisions, approvals, payment status, and audit events. Migration records may contain Stripe customer, subscription, product, price, schedule, and invoice identifiers, plus invoice statuses, amounts, and dates.

Stripe restricted keys are used only to run the migration steps you authorize and, until the keys are deleted, to read invoices after your renewals and confirm each subscription moved over without a second charge. They are encrypted before storage. Stripe Checkout processes your payment details; SubPorter stores the Checkout session identifier, amount, status, and payment date, not your card details.

Where information is processed

Cloudflare hosts SubPorter. Service records are stored in Cloudflare D1, and migration records are stored in Cloudflare R2. Stripe provides Checkout and the Stripe APIs used for your migration.

We share information with these providers only as needed to operate SubPorter, or when required by law. We do not sell personal information.

Analytics

SubPorter uses PostHog to measure page visits and the steps from starting a migration through payment. Before sign-in, PostHog uses an anonymous browser identifier stored without cookies. After sign-in, it uses your internal SubPorter user ID. We respect Do Not Track and disable session recordings. We do not send Stripe keys, customer data, project names, email addresses, or migration contents to PostHog.

Retention

Encrypted Stripe keys are deleted 30 days after a project is completed. For an incomplete project, they are deleted after 30 days of inactivity.

Other account, project, payment, summary, and audit records, and the migration records, are kept as needed to provide the service. To request access, correction, or deletion, contact support@subporter.com. Some records may need to be retained for legal, security, or payment purposes.
