FAQ

Frequently Asked Questions

Need help with something? Here are our most frequently asked questions.

How does the product work?

Good question, why we need a tab manager that live in your side panel. But when you have used the Vertical tabs in Microsoft Edge browser or the Window Panel in Vivaldi browser, you will understand, because using a side panel to manage tabs is really convenient.

Side Space is a Chrome browser extension created to fill the empty side panel area. It provides tab management capabilities in this previously unused space.

Why do I need to sign in?

Side Space currently offer two optional third-party login options, Google and GitHub. Logging in with these accounts allows you to sync your data to the cloud.

This means that when you log in to another browser or device with your account, your saved spaces will be synchronized.

What does "lifetime" mean?
Is it a one-time payment?
Is there a free version available?
What is your refund policy?

If there are any serious issues with the license, reach out and let us know via support@sidespace.app within 7-days and we'll issue a full refund.

You'll no longer be able to saving or access more than 5 spaces if we issue a refund. But we can help you saving the tabs in the cloud for 30-days in case you want to recover your spaces again. We think that's pretty fair! You can read the full refund policy in the License Agreement.
