Warranty

Last updated: August 29, 2026

SereniBrain headbands include a 12-month limited warranty beginning on the original purchase date.

What the warranty covers

The warranty covers defects in materials and workmanship that occur during normal, intended use of the SereniBrain headband. It applies to the original purchaser and requires valid proof of purchase.

What the warranty does not cover

• Damage caused by accidents, impact, misuse, improper storage, unauthorized modification, or repair.
• Water or liquid damage, including submerging the device.
• Normal cosmetic wear, scratches, discoloration, or expected battery capacity reduction.
• Consumable or replaceable items, including hydrogel electrode pads, unless they were defective when delivered.
• Damage caused by using incompatible chargers, accessories, or instructions not supplied by SereniBrain.
• Products without valid proof of purchase or with altered identifying information.

How to make a warranty claim

Email support@serenibrain.com with your order number, purchase date, a description of the problem, and clear photos or video where helpful. Do not send the product back until you receive return instructions.

Available remedies

After reviewing the claim, SereniBrain may provide troubleshooting, replacement parts, repair, replacement, or another appropriate remedy. The solution and any shipping arrangements depend on the issue, location, availability, and applicable law. Replacement products or parts may be new or functionally equivalent.

Consumer rights

This limited warranty is in addition to rights that cannot be excluded under applicable consumer law. Nothing in this warranty limits those mandatory rights.
