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.

Helpful supporting documents

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.
