This steemit utility allows you to claim rewards in the browser. The private posting key is required and it will neither be stored in your browser nor uploaded. You can keep this page open and let the utility claim your balances to your steem account.
To claim the Scot Tokens (issued on steem-engine.com), please use this tool instead: Claim Scot Tokens. You can open this tool at different pages/tabes to claim for multiple accounts.
Claiming Rewards Locally (This Free Tool) is suitable for: those who worry about storing Private Keys in the server; those who do not know/manage VPS server; those who do not want to authorize to third party accounts because either they worry about leaking the keys or simply because the third-party service is not FREE.
