Unlike with crypto exchanges and web wallets, you don't have an 'account' with Klever wallet. All your private data is stored locally on your device, which means no one but you—including us or any third-party service—can access it. So in case you want to leave us, simply transfer your remaining funds elsewhere and stop using your Klever wallet.
We've been glad to have you on board and are sorry to see you go!
If you have any questions, need any help, or want to leave us some feedback, feel free to reach out to our support team via https://klever.zendesk.com/hc/en-us/requests/new
