đ Security Best Practices
Encrypted Storage
API keys are encrypted with Base64 encoding before storage in your browser's localStorage.
Local Only
Your API keys never leave your browser. They're not sent to our servers or any third parties.
Rotate Keys
Regularly rotate your API keys and delete unused ones to maintain security.
Free Tiers
Start with free tier API keys. Monitor usage to avoid unexpected charges.
