• Reload instantly when clicked
• Free up memory while inactive

🔒 PRIVACY:
• No data collection by default
• Optional anonymous error reporting (disabled by default, fully transparent)
• When enabled: errors anonymized, PII redacted, max 100/day, 30-day retention
• All settings stored locally on your device
