Back up your data
Before canceling, export or back up all data from your QuestDB Cloud instance. Use the QuestDB web console or REST API to export tables as CSV, or use COPY TO to export data to your own storage.
Check your subscription source
Determine how you subscribed: directly via QuestDB (questdb.com) or through AWS Marketplace. This determines your cancellation path. Note: QuestDB Cloud (managed) has been discontinued — current users may be on legacy plans or QuestDB Enterprise (BYOC).
Cancel via AWS Marketplace (if applicable)
If you subscribed through AWS Marketplace, log in to your AWS Console, navigate to AWS Marketplace > Manage subscriptions, find the QuestDB Cloud listing, and choose 'Cancel subscription'. Select your reason and confirm cancellation.
Send written cancellation notice to QuestDB
For direct subscriptions or QuestDB Enterprise, send an email to support@questdb.io stating your intent to cancel. Include your account name, registered email address, and requested termination date. Per the Terms of Service, cancellation is effective upon written notice.
Request pro-rata refund
In the same cancellation email, request a pro-rated refund for any pre-paid fees covering service time after your cancellation date. Per QuestDB's Terms of Service, you are entitled to a pro-rated refund for unused pre-paid service. For AWS Marketplace subscribers, refunds are at QuestDB's discretion.
Await confirmation
Wait for a confirmation email from QuestDB support acknowledging your cancellation. Retain this confirmation for your records. Access to your instance will end on the confirmed termination date.
