DURIN LIMITED HARDWARE WARRANTY

Durin, Inc.  |  440 N Wolfe Rd, Sunnyvale, CA 94085

Effective Date: October 1, 2026   |   Version 1.1

Applies to: Durin Door Manager, SKU DDM-000-OBM, sold by Durin, Inc. or by retailers in the United States and Canada.


This is a Limited Warranty. Please read it in full. It describes what Durin covers, for how long, what you need to do to make a claim, and the limits that apply.

1. Who Gives This Warranty, and Who It Covers

This Limited Warranty is given by Durin, Inc., 440 N Wolfe Rd, Sunnyvale, CA 94085 ("Durin").

This warranty is extended only to the original end-user purchaser of the product. It is not transferable. It does not extend to any subsequent owner, whether the product is resold on its own or transferred together with a property.

2. What Is Covered

Durin warrants that the Durin Door Manager (SKU DDM-000-OBM) will be free from defects in materials and workmanship under normal use for a period of one (1) year from the date of purchase.

Coverage extends to the Door Manager unit and to the mounting panel and mounting kit supplied in the box, including the screw and adhesive pad options.

3. What Durin Will Do

If a covered defect appears during the warranty period, Durin will, at its option, either:

  • replace the product with a new or refurbished unit of the same model or a functionally equivalent model; or

  • refund the net purchase price paid for the product, excluding shipping charges and taxes.

Durin does not offer repair service for this product. All approved claims are resolved by replacement or refund.

A replacement unit is warranted for the remainder of the original warranty period or for ninety (90) days from the date the replacement is shipped, whichever is longer. The unit it replaces becomes the property of Durin. The warranty period is extended by any period during which the product is out of your possession for warranty service.

4. What Is Not Covered

This warranty does not cover:

  • Damage caused by misuse, abuse, accident, or unauthorized modification.

  • Normal wear and tear.

  • Cosmetic damage that does not affect the product’s function, including scratches, dents, discoloration, and finish wear.

  • Damage resulting from installation contrary to the Quick Installation Guide supplied with the product, or from operation outside the product’s intended use.

  • Batteries and other consumable items, except where the failure results from a defect in materials or workmanship in the product itself.

  • Damage caused by an improper power supply or power surge, or by environmental conditions outside the product’s published operating range.

  • Damage actually caused by a third-party product or accessory used with the Door Manager.

  • Loss or theft of the product.

  • Products whose serial number has been removed or rendered illegible, where Durin cannot otherwise verify the unit.

Third-Party Products and Services

This warranty is not conditioned on your use of any particular brand of lock, accessory, part, or service. The exclusion above applies only where a third-party product or accessory is the actual cause of the defect or damage claimed.

Compatibility

The Durin Door Manager is designed to add features to compatible third-party smart locks. Incompatibility between the Door Manager and a particular lock model is not a defect in materials or workmanship and is not covered by this warranty. Please consult Durin’s published compatibility list before purchase.

5. Software, Firmware, and Connected Services

This warranty covers hardware only.

Durin Door Manager software, firmware, mobile applications, and cloud services — including Aliro credential issuance, face and voice verification, and entry event reporting — are licensed and not sold. They are governed solely by the Durin Terms of Service at durin.ai/pages/terms-of-service and the Durin Privacy Policy at durin.ai/pages/privacy-policy. Nothing in this warranty creates any warranty covering software or connected services.

No paid subscription is required to use the features described in Durin’s published product documentation for the Door Manager.

Security Update Support Period

Durin will make security and firmware updates available for the Durin Door Manager (SKU DDM-000-OBM) for at least three (3) years from the last date on which Durin offers this model for sale. The applicable end-of-support date is published at durin.ai/pages/warranty.

End-of-Service Notice

If Durin discontinues a cloud service that the Door Manager requires in order to deliver a feature described in its published product documentation, Durin will give affected users at least six (6) months’ advance notice.

The commitments in this Section 5 are fixed at the version of this warranty in effect on your date of purchase.

6. How to Obtain Warranty Service

Registration is not required. Coverage under this warranty does not depend on registering the product with Durin.

To make a claim:

  1. Email Durin Support at support@durin.ai. Support is available Monday through Friday, 12:00 p.m. to 5:00 p.m. Eastern Time, excluding holidays.

  2. Provide proof of purchase showing the purchase date and the seller, the product serial number, and a description of the problem.

  3. Cooperate with remote diagnosis. Durin Support will review device diagnostics and entry logs to confirm the fault. Do not ship the product to Durin before receiving return authorization.

Advance Replacement

Once Durin confirms a covered defect, Durin ships a replacement unit before the defective unit is returned. No authorization hold is placed on your payment method.

A prepaid return label is provided. The defective unit must be returned within thirty (30) days of the date the replacement is shipped. If it is not returned within that period, Durin may invoice you for the replacement unit at Durin’s then-current retail price.

Durin pays shipping in both directions, including cross-border shipping, duties, and brokerage charges for claims originating in Canada.

Durin does not operate walk-in service or repair facilities. All service under this warranty is performed by mail-in advance replacement as described above.

Claims must be submitted within the warranty period.

7. Limitation of Implied Warranties

TO THE EXTENT PERMITTED BY LAW, ANY IMPLIED WARRANTIES, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION TO THE ONE (1) YEAR TERM OF THIS WRITTEN WARRANTY.

Some States do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.

For the avoidance of doubt, and notwithstanding Section 31 of the Durin Terms of Service, Durin does not disclaim implied warranties with respect to Durin Door Manager hardware. Implied warranties are limited in duration as stated above, and no further.

8. Limitation of Liability

TO THE EXTENT PERMITTED BY LAW, DURIN IS NOT LIABLE FOR ANY INCIDENTAL, CONSEQUENTIAL, INDIRECT, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATING TO THE DURIN DOOR MANAGER OR THIS WARRANTY, INCLUDING WITHOUT LIMITATION LOSS OF OR DAMAGE TO PROPERTY, UNAUTHORIZED ENTRY, LOSS OF USE, LOSS OF DATA, AND THE COST OF SUBSTITUTE PRODUCTS OR SERVICES.

Some States do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

Durin’s aggregate liability is capped as set out in Section 37 of the Durin Terms of Service at durin.ai/pages/terms-of-service.

The Durin Door Manager is an accessory that adds features to an existing lock. It is not a life-safety device and is not a substitute for a monitored alarm system, insurance, or reasonable physical security precautions.

9. Your Exclusive Remedy

Replacement or refund as described in Section 3 is your exclusive remedy under this warranty. If that remedy is determined to have failed of its essential purpose, the limitations set out in Sections 7 and 8 continue to apply to the fullest extent permitted by law.

10. Governing Law and Dispute Resolution

This warranty is governed by the laws of the State of Delaware, without regard to its conflict of law principles.

Any dispute arising out of or relating to this warranty is subject to binding individual arbitration under Section 40 of the Durin Terms of Service at durin.ai/pages/terms-of-service, and not to court proceedings, except as that Section provides.

Durin does not operate an informal dispute settlement mechanism under 16 C.F.R. Part 703.

11. Purchasers in Canada

This warranty is offered in Canada in addition to, and does not limit, the rights and remedies available to consumers under applicable federal and provincial consumer protection legislation.

Where provincial law prohibits or restricts any exclusion, limitation, or disclaimer contained in this warranty, that provision applies only to the extent the law permits, and the remainder of this warranty continues in full force and effect.

12. Other Terms

Your Legal Rights

This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

Which Version Applies

The version of this warranty in effect on your date of purchase governs that purchase. The version number and effective date appear at the top of this document. The current version is published at durin.ai/pages/warranty.

Severability

If any provision of this warranty is held to be unenforceable, that provision applies to the maximum extent permitted, and the remaining provisions remain in full force and effect.

Entire Warranty

This document is the entire warranty Durin offers for the Durin Door Manager. No dealer, retailer, agent, or employee of Durin is authorized to modify this warranty or to make any additional warranty on Durin’s behalf.
