Uninstalling your app or deactivating your account doesn't automatically cancel your subscription. All cancellations must be carried out through the platform you used to buy the subscription.
If you purchased your subscription from:
Twitter for iOS: cancel from your Apple device’s Account Settings or in the “Subscriptions” section of the App Store.
Google: cancel your subscription by visiting the Subscriptions section of the Google Play Store.
Twitter.com: cancel your subscription by navigating from your profile menu to the Subscription section under Twitter Blue. Please note that subscriptions purchased on twitter.com will automatically cancel if you deactivate your account.
For people living in the UK or parts of the EU where Twitter Blue is available for purchase: If you wish to exercise a right of withdrawal, you can find Apple's and Google's respective cancellation instructions, related refund policies, and model cancellation form for the App Store here and for Google Play here. For purchases made on twitter.com through our payment partner Stripe we recommend submitting your request from the Get support form found in your Twitter Blue settings. You can also download and submit this form by mail to:
Twitter International Company,
One Cumberland Place,
Fenian Street Dublin 2, D02
Attn: Twitter Blue Customer Support
Note: Cancel your subscription at least 24 hours before the auto-renewal period, to avoid further charges. Canceling won’t give you a refund for fees already paid, but your features won’t expire until the end of the period you’ve already paid for.
