cancellation Cosine: Easy Method

What is Cosine

Overview

Cosine is an online subscription-management platform that helps users manage recurring services, track spending, and cancel unwanted subscriptions.

Services

The platform offers task-based plans, project limits, and per-user seats to fit individuals and teams. Documentation and support are available on the official help site.


How to cancel Cosine

Accepted cancellation methods

Cosine accepts cancellations via account settings, email support, and in some cases by postal letter to the company address.

The fastest method is contacting support through the official help pages. A 7 days' notice before the renewal date is required.

Step-by-step cancellation (recommended)

  • Sign in to your Cosine account on cosine.sh.
  • Open Account or Billing settings and select “Cancel subscription” or equivalent option.
  • Confirm cancellation and note the renewal date; provide at least 7 days' notice before renewal.
  • If you prefer support, open the official FAQ/contact page and send a cancellation request: include your account email, subscription plan, and reason for cancelling. See Cosine FAQs.
  • For postal cancellation, send a signed letter with account details to the company address and keep proof of posting.

What happens when you cancel

Access and billing

After you cancel, your subscription remains active until the end of the current billing cycle.

Automatic renewal stops after the billing period ends; payments already charged are retained and not refunded.

Data and account

Your account and stored data typically remain accessible according to Cosine’s retention practices; export important data before the end of your billing period.

If you need data removal, contact support through the official documentation pages for instructions.


Will I get a refund?

Official refund policy

Cosine’s policy states that payments already made are non-refundable. There is no refund provision after cancellation or for non-use.

Reference: see the official FAQs for the current policy at Cosine FAQs.

Possible exceptions

Exceptions are uncommon; if local law requires a refund in a specific case, you should raise the issue with Cosine support and, if needed, with local consumer authorities.

Keep documentation of charges and communication if you plan to dispute a transaction through your bank or a regulator.

Your consumer rights in United Arab Emirates

Local law overview

UAE consumer protection covers unfair commercial practices and provides channels for complaints via government portals.

Some jurisdictions offer a 14-day “cooling-off” for digital purchases, but this is not guaranteed for every service under local rules.

How Cosine’s policy interacts with UAE rights

Cosine does not offer a 14-day automatic refund or cooling-off; it requires 7 days' notice to cancel and states payments are non-refundable.

If you believe your rights under UAE law entitle you to a refund, gather evidence and contact the UAE consumer protection authority at u.ae - Consumer Protection.


Customer experiences

Positive feedback

Customers commonly report that Cosine’s team is professional, knowledgeable, efficient, and responsive when handling support requests.

Many users appreciate the platform’s task and project structure for subscription management.

Negative feedback

Some users have described the overall service as average, noting that outcomes did not always meet expectations despite helpful staff.

Refund limitations and the lack of a cooling-off refund have been points of concern for a subset of users.


Documentation checklist

Required information

  • Account email and username
  • Subscription or invoice ID
  • Payment method and date of charge

Helpful supporting documents

  • Screenshots of billing and subscription pages
  • Copy of cancellation confirmation or support ticket
  • Postal proof if cancelling by letter

Common mistakes

Missing the 7-day notice

Example: Requesting cancellation two days before renewal often results in the subscription renewing for another period.

Remedy: Submit cancellation at least 7 days before the renewal date and keep confirmation.

Not saving confirmation

Example: Users assume verbal or informal messages suffice and later cannot prove cancellation.

Remedy: Always request written confirmation via email or support ticket and archive it.

Assuming automatic refunds

Example: Cancelling early and expecting a prorated refund can lead to disputes because Cosine’s policy states payments are non-refundable.

Remedy: Review the refund policy before cancelling and decide whether to use the service until the period ends.


Comparative recap

Plan comparison

Plan Price (AED/month) Tasks/month Projects Seats Cancellation notice Refunds

Hobby Plan AED 73.45 80 Up to 10 Individual seat 7 days No refunds
Professional Plan AED 363.60 240 Up to 100 Per-user seat 7 days No refunds

Key takeaway

All plans require a 7 days' notice to cancel before renewal and share the same non-refundable payment policy. Choose plans knowing refunds are generally not available.
