How is a dark pattern score decided?

Each tool gets a rating from 1 to 10 for how much effort the company requires to cancel, based on its published policies and documented customer complaints. Adobe scores 9 out of 10, largely because of the early termination fee on annual plans. A high score means cancelling takes more work, not that the company is doing anything unlawful.

What do high, medium and low risk mean?

High risk (8 to 10) means known dark patterns. Medium risk (6 to 7) means some concerns. Low risk (1 to 5) means generally fair billing. Lower is better.

What if a tool I pay for is not on the list?

BillSensor detects 63 SaaS tools. For anything else, add the subscription yourself with "+ Add Subscription Manually" in the extension popup. Manually added tools have no score, because scores exist only for the 63 tracked tools.

Which scores and cancel links do I see on each plan?

The scorecard on this page is public for all 63 tools. Inside BillSensor, Free shows the score and the cancel link for your 3 lowest-cost subscriptions, and Pro and Business show them for every subscription.

Can BillSensor cancel a subscription for me?

No. Each card links to the company's own cancellation page, but you complete the cancellation with that company. BillSensor also cannot block a payment or reverse a charge that has already gone through. More answers about scores and cancelling are in the BillSensor support hub

Which SaaS tools are billing you unfairly?

We score tools on their billing practices: how hard they make it to cancel, whether they charge after cancellation, and if they use silent upgrades. Lower is better. Tools we are still researching are marked Not yet scored.

High Risk (8-10): Known dark patterns

Medium Risk (6-7): Some concerns

Low Risk (1-5): Generally fair billing

Not yet scored: Research in progress

How a score is decided

Each tool is scored from 1 to 10 on six factors, weighted by how much harm they can cause. A tool can score on more than one factor. The "Why this score" line on each card names the main tactic we found.

+3Post-cancellation charges confirmed by verified user complaints

+3Early termination fee not clearly disclosed at sign-up

+2No cancel button, so it needs phone, chat or human contact

+2Hidden cancellation flow with 3 or more friction screens

+1Silent auto-renewal with no advance notice

+1Seat or feature additions billed without explicit consent

Scores draw on published policies, verified complaint patterns and direct checks of each cancellation flow, as of October 2026. They are our assessment, not a statement about a company's intent. If you spot an error, tell us.
