Frequently Asked Questions

Can I use the extension without an account?

Yes! Basic dark mode works without any account. You need an account and an active subscription for cloud backup, editing custom site lists, and sync across devices.

What happens when my subscription expires?

You'll be downgraded to the Free plan. Local data remains, but cloud sync and subscription-only editing features stop until you renew.

Is my browsing data private?

Completely. We never collect or transmit your browsing history. The extension works locally; only your account email and synced settings (that you choose to upload) touch our servers.

Can I get a refund?

Yes. We offer a 14-day money-back guarantee. Contact us within 14 days of purchase and we'll issue a full refund, no questions asked.
