How can we help?
Answers to the questions we hear most, and a direct line to us when you need one.
Getting started
How do I install Activity Cleaner?
Open the Chrome Web Store page, click Add to Chrome, then pin the extension to your toolbar so it’s easy to find. It works in Google Chrome, Microsoft Edge and Brave on desktop.
How do I start my first clean-up?
Open LinkedIn and sign in as usual. Click the Activity Cleaner icon, pick a tool and follow the steps. You’ll review everything it finds before anything is removed.
How many removals do I get for free?
The free plan includes 10 removals a day across all five tools, and the count resets every day. Pro removes the limit.
Does it work on my phone?
Not yet. Activity Cleaner is an extension for desktop browsers.
Your license
Where do I find my license key?
Your key is shown on screen straight after checkout, and we email it to you too. Lost it? Enter your email on your license page and we’ll send it again straight away.
How do I switch on Pro?
Open Activity Cleaner, choose Upgrade and paste your license key. Pro switches on straight away.
How many browsers can I use?
One license key works in up to three browsers at a time. To move it, open Activity Cleaner in the old browser, choose Settings and select Remove next to This browser, then activate the key in the new one. A browser that hasn’t been used for 45 days frees up on its own, and you can always email us to reset it.
Billing and refunds
How do I cancel my subscription?
Go to your license page and choose Manage subscription, use the link in your Paddle receipt email, or email us and we’ll do it for you. Pro keeps working until the end of the period you’ve already paid for, and you won’t be charged again.
What happens if a payment fails?
Pro pauses until the payment goes through. Paddle emails you and tries the payment again, and as soon as it succeeds, Pro switches back on by itself, with nothing for you to re-enter. You can update your card any time on your license page.
How do I get a refund?
If the problem is with the extension, email us first, as our team can usually fix it quickly. If we can’t, or Pro isn’t right for you, ask within 14 days of your payment and we’ll refund it in full. Requests made more than 14 days after a payment can’t be refunded. Read the full refund policy.
Where can I find my receipt or invoice?
Paddle emails you a receipt after every payment. You can also look up your orders at paddle.net.
What will I see on my bank statement?
Card payments appear as PADDLE.NET followed by LUMENHART. PayPal payments show as PAYPAL *PADDLE.NET.
Privacy and safety
Can you see my LinkedIn content?
No. Your posts, comments and other activity are read in your own browser and are never sent to us.
Is it safe for my LinkedIn account?
Activity Cleaner removes items at a measured pace and pauses automatically if LinkedIn asks it to slow down. For very large clean-ups, the slower speed setting is the most cautious choice.
LinkedIn decides how its own platform works and may limit activity at any time, so we can’t promise how it will respond. Please use your own judgement, especially with big batches.
What information do you collect?
Only what we need to run the free plan and your license, such as your Chrome profile email and your license key. Our Privacy Policy explains everything in plain language.
Still need help?
Email us and a real person will get back to you. Include the email you bought with if your question is about an order.
