How hard is it to cancel ClickHouse?

ClickHouse Cloud has no one-click self-serve cancel button. To stop charges you self-serve stop and delete your services in the console (services are billed by usage). To formally CLOSE the account you must: export data, stop/delete all services, remove all users except the requesting admin, ensure all charges are paid, then sign in and click the Help (question-mark) icon, choose 'Create case' under Support, set Severity 3 with subject 'Please close my ClickHouse account', and submit. ClickHouse confirms closure by email. Accounts with unpaid balances cannot be closed. No notice period, refund, or proration terms are documented. For data deletion, use the same support case with subject 'Please close my ClickHouse account and delete my personal data' — completed within 30 days and irreversible. PAYG cloud-marketplace subscriptions (AWS/GCP/Azure) are managed/cancelled through the respective marketplace; if a marketplace subscription is cancelled, billing falls back to the credit card on file.

How to cancel ClickHouse

• Channels: online (self-serve), live chat
• Official cancellation page: https://clickhouse.com/docs/cloud/manage/close_account
• Pause/freeze: not offered. No pause or freeze option is documented. To stop incurring charges you must stop and delete services; closing the account itself requires a support case. Closed accounts may be reopened at any time to start new services.
• Account/data deletion: Personal data deletion is available via the same support case: file a case through the console Help button and change the subject to 'Please close my ClickHouse account and delete my personal data.' ClickHouse states it completes personal data deletion requests within 30 days. This is irreversible — the account cannot be reopened afterward. https://clickhouse.com/docs/cloud/manage/close_account

Scope & fairness

This is the Documented-Policy tier: it measures how clearly the cancellation policy is published (cited, dated facts), not the behavioural experience of cancelling (Verified-Flow audit pending). Every company is scored on the same five dimensions with the same published weights — scores cannot be bought or removed. It is opinion grounded in disclosed facts, and not legal advice.
