Many Amazon sellers use Arbitrage Cyclops to find profitable deals and Profit Cyclops to run the rest of their business. Until now that meant two logins, two passwords and two subscriptions. Today we are connecting the two tools, and the connection works in both directions:
- Profit Cyclops → Arbitrage Cyclops - sign in to Arbitrage Cyclops with your Profit Cyclops account. Profit Cyclops Plus plans and above include full Arbitrage Cyclops access.
- Arbitrage Cyclops → Profit Cyclops - sign in to Profit Cyclops with your Arbitrage Cyclops account. A paid Arbitrage Cyclops subscription unlocks Profit Cyclops Plus features.
Whichever tool you started with, one paid plan now gets you into both. This guide explains how each direction works, which plans qualify, what happens to the accounts you already have, and how to fix the most common sign-in problems.

For Profit Cyclops Users: Sign In to Arbitrage Cyclops
How to Continue with Profit Cyclops
- Go to the Arbitrage Cyclops sign-in page (or the sign-up page if you are new).
- Click Continue with Profit Cyclops. A small Profit Cyclops window opens.
- Sign in to Profit Cyclops if you are not already signed in, and approve the request.
- The window closes and you are signed in to Arbitrage Cyclops, ready to search for deals.
Popup Blocked?
If your browser blocks the Profit Cyclops window, Arbitrage Cyclops automatically switches to a full-page redirect instead, so you can still sign in. You can also allow popups for arbitragecyclops.com to keep the faster popup experience.
Which Profit Cyclops Plans Include Arbitrage Cyclops?
Any Profit Cyclops user can sign in with Profit Cyclops. Full Arbitrage Cyclops access is included with the Plus, Enterprise and Enterprise+ plans, as long as the subscription is active or in its trial period. On Starter or Standard you can still use your Profit Cyclops login and pick an Arbitrage Cyclops plan on our pricing page, or upgrade your Profit Cyclops plan to Plus.
Already Paying for Arbitrage Cyclops?
If you have an active Arbitrage Cyclops subscription, it keeps working as before and takes priority. Your Profit Cyclops plan only grants access when you do not have an active Arbitrage Cyclops subscription.
What Happens to My Existing Arbitrage Cyclops Account?
Nothing is lost. The first time you continue with Profit Cyclops, we match your account by email address. If the email is the same on both tools, your Profit Cyclops account is linked to your existing Arbitrage Cyclops account and your favorites, scans, exports and settings are all still there. If you do not have an Arbitrage Cyclops account yet, we create one for you using your Profit Cyclops name and email. One Arbitrage Cyclops account can be linked to only one Profit Cyclops account.
Managing Your Plan
When your access comes from Profit Cyclops, billing is handled by Profit Cyclops and your Arbitrage Cyclops account settings show your plan as "Active via Profit Cyclops". Manage upgrades, downgrades and cancellations on Profit Cyclops. Arbitrage Cyclops picks up your latest plan the next time you sign in with Profit Cyclops, so after an upgrade, sign out and continue with Profit Cyclops again to unlock access right away.

How to Sign In to Profit Cyclops with Arbitrage Cyclops
- On Profit Cyclops, choose the option to sign in with Arbitrage Cyclops.
- You are taken to Arbitrage Cyclops. Sign in with your usual email and password or with Google.
- Review what will be shared with Profit Cyclops and click Allow.
- You are sent back to Profit Cyclops and signed in.
Before anything is shared, Arbitrage Cyclops shows you exactly what Profit Cyclops will receive: your email address, your name, your subscription plan and status, and your subscription end date. If you are signed in to the wrong account, click Not you? to switch. If you click Cancel, nothing is shared and you are returned to Profit Cyclops.
What Your Arbitrage Cyclops Plan Unlocks
With a paid Arbitrage Cyclops subscription, you can use Profit Cyclops Plus features without buying a separate Profit Cyclops plan. Your Arbitrage Cyclops billing stays exactly as it is; manage it on your Arbitrage Cyclops account page as usual.
Need an Arbitrage Cyclops Account First
This direction works with existing Arbitrage Cyclops accounts only. If you are new, create your Arbitrage Cyclops account and choose a plan first, then sign in to Profit Cyclops with it.
Profit Cyclops receives your current plan status each time you sign in with Arbitrage Cyclops. If you upgrade or renew, sign in to Profit Cyclops with Arbitrage Cyclops again so it sees your latest plan.
Privacy and Security
- Only the basics are shared - name, email address, and plan name, status and dates. Your Amazon seller data, your saved products and your passwords are never shared in either direction.
- You approve every connection - each sign-in is a request you confirm. Nothing is shared in the background.
- Encrypted, single-use, short-lived - sign-in data is encrypted, can be used only once, and expires within minutes.
- Verified emails only - Arbitrage Cyclops links a Profit Cyclops account only when its email address is verified, so nobody can take over your account just by using your email on the other tool.
Troubleshooting
"Please verify your email address on Profit Cyclops first"
For your security, Arbitrage Cyclops only accepts Profit Cyclops accounts with a verified email address. Verify your email on Profit Cyclops, then click Continue with Profit Cyclops again.
"This account is already linked to a different Profit Cyclops account"
Your Arbitrage Cyclops account was previously linked to another Profit Cyclops login. Make sure you are signed in to the right Profit Cyclops account, or contact our support team and we will help you move the link.
"This sign-in link is invalid or expired"
Each sign-in request is valid for a few minutes and can be used only once. Start the sign-in again from the beginning on the tool you are trying to use.
Signed in, but features are still locked
Check that your plan qualifies: Profit Cyclops Plus or higher for Arbitrage Cyclops access, or a paid Arbitrage Cyclops plan for Profit Cyclops Plus features. Then make sure the plan is active. If you changed your plan recently, sign out and sign in again through the other tool so your latest plan details are picked up.
Frequently Asked Questions
Can I still sign in with my email and password?
Yes. Signing in through the other tool is an extra option on both sides. Your existing email and password or Google sign-in keep working.
Do I need to pay for both tools?
No. A Profit Cyclops Plus plan or higher includes Arbitrage Cyclops, and a paid Arbitrage Cyclops plan includes Profit Cyclops Plus features. Pick the subscription that fits you best and use both tools.
What happens if I cancel my plan?
Your accounts and saved data remain on both tools. Access that came from the cancelled plan ends when that plan ends. You can subscribe directly on either tool at any time, for example on our pricing page.
