Klackey End User License Agreement

Effective date: August 10, 2026

This End User License Agreement (the "Agreement") is a legal agreement between the individual accepting it ("you") and Klackey, LLC ("Klackey," "we," "us," or "our") for the Klackey desktop software, including its documentation and updates (the "Software").

By selecting an option indicating acceptance, installing, activating, or using the Software, you agree to this Agreement. If you do not agree, do not install, activate, or use the Software.

1. License Grant

Subject to your compliance with this Agreement and payment of all applicable charges, Klackey grants you a limited, non-exclusive, non-transferable, revocable, perpetual license to install and use the Software on up to two devices at the same time.

The license is assigned to one user. The two permitted installations are intended to allow that user to use Klackey on two devices, such as a work computer and a home computer. The license may not be shared by two users. A business must obtain a separate license for each user, unless Klackey provides different written licensing terms for a business purchase.

The devices may be owned or controlled by you, including an employer-owned device assigned primarily to you, provided that installation is permitted by the device owner and the Software is used by the licensed user.

"Perpetual" means that your right to use the versions covered by your license does not expire solely because the update period described in Section 4 ends. The Software remains subject to periodic license validation as described in Section 5.

2. Trial Period

Klackey may provide a full-featured free trial for 14 days. No payment card is required for the trial. The trial is intended to let you evaluate compatibility, functionality, and suitability before purchasing.

The trial period and trial eligibility may be enforced using a pseudonymous device identifier as described in the Klackey Privacy Policy. Attempting to reset, bypass, or manipulate the trial period is prohibited.

Trial Software is provided under the same warranty disclaimers and liability limitations that apply to purchased Software.

3. License Key and Activations

A purchased license key permits up to two simultaneous device activations for one licensed user.

You may deactivate an installation through the Software to free an activation for another device. Repeated or automated activation transfers, activation sharing, or other activity reasonably indicating use by multiple users may result in suspension of the license key while the activity is investigated.

You are responsible for keeping your license key confidential. You must promptly contact Klackey if you believe that your key has been lost, stolen, publicly disclosed, or used without authorization.

License keys are issued and validated through Lemon Squeezy, which acts as merchant of record and licensing provider. Purchases are also subject to the Lemon Squeezy terms presented at checkout.

4. Updates and Support Period

Your initial purchase includes access to Software updates released during the 12-month period beginning on the date of purchase (the "Update Period"). Updates may include new features, compatibility changes, bug fixes, and security fixes.

When the Update Period ends:

Klackey may, at its discretion, provide an update outside an active Update Period, but doing so does not create an obligation to provide any other update or support.

You may purchase an update renewal that begins a new 12-month Update Period on the renewal purchase date. Klackey may offer existing licensed users a renewal discount of up to 50 percent off Klackey's then-current list price for a new license. The availability and amount of any renewal discount may vary based on timing, product version, region, currency, taxes, promotions, or business arrangements. Unless Klackey expressly states otherwise in writing, a particular discount is not guaranteed for future renewals.

Klackey does not guarantee any release schedule, feature roadmap, operating-system compatibility period, or minimum number of updates. Klackey may discontinue support for an operating system, hardware platform, integration, or Software version when continued support is no longer commercially or technically reasonable.

5. Internet Connection and Periodic Validation

An internet connection is required for initial activation and periodic license validation through Lemon Squeezy.

The Software attempts to validate an activated license periodically. A successfully validated installation may generally operate for up to 14 days without another successful validation. Temporary connection failures during that period do not immediately restrict the Software.

If the Software cannot successfully validate the license before the validation period expires, the Software enters a restricted state until validation succeeds. In the restricted state:

You may manually retry validation. Full licensed functionality resumes when Lemon Squeezy confirms a valid license, without requiring a new purchase. Klackey is not responsible for temporary restrictions caused by loss of internet access, firewall or network configuration, incorrect system time, third-party service interruption, a disabled or refunded license, or other conditions outside Klackey's reasonable control.

Nothing in this section permits Klackey to prevent you from viewing or exporting your locally stored content solely because periodic validation is unavailable.

6. Restrictions

You may not:

You may make reasonable backup copies of the Software solely to support your licensed use.

7. Ownership and Your Content

The Software is licensed, not sold. Klackey and its licensors retain all right, title, and interest in the Software, its design, code, documentation, trademarks, and other intellectual property.

You retain ownership of content that you create, copy, store, or import into the Software. This Agreement does not grant Klackey ownership of your clippings, notes, folders, tags, abbreviations, backups, or other user content.

Klackey is designed to store user content locally. You are responsible for maintaining appropriate backups and for determining whether the Software is suitable for content subject to confidentiality, employment, regulatory, or records-management requirements.

8. Third-Party Services and Components

The Software may communicate with or rely on third-party services, including Lemon Squeezy for purchase and license validation and Cloudflare for limited online services. Those services are governed by their own terms and privacy practices.

The Software may include open-source or third-party components governed by separate license notices. Those notices control solely with respect to the applicable components.

Klackey does not control third-party services and does not guarantee that they will remain available, unchanged, or compatible with the Software.

9. Refunds

Klackey provides a full-featured, no-credit-card-required 14-day trial so that you can evaluate the Software before purchasing. Except where required by applicable law or authorized by Lemon Squeezy under its Buyer Terms, purchases are final and non-refundable.

Purchases are processed by Lemon Squeezy as merchant of record. Refund requests, payment disputes, chargebacks, taxes, and transaction remedies are subject to the Lemon Squeezy Buyer Terms presented at checkout and to applicable law. Lemon Squeezy may approve or deny a refund in accordance with those terms, independently of this Agreement.

The absence of a voluntary refund does not limit any non-waivable right or remedy available under applicable consumer law. If technical problems prevent or unreasonably delay delivery of the purchased license, the remedies stated in the Lemon Squeezy Buyer Terms and applicable law will apply.

Questions concerning installation or activation should first be directed to Support@Klackey.com so that Klackey has a reasonable opportunity to assist.

10. No Warranty

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SOFTWARE, TRIAL, DOCUMENTATION, UPDATES, AND SUPPORT ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS. KLACKEY DISCLAIMS ALL EXPRESS, IMPLIED, AND STATUTORY WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, QUIET ENJOYMENT, ACCURACY, AND SYSTEM INTEGRATION.

KLACKEY DOES NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, COMPATIBLE WITH EVERY APPLICATION OR OPERATING SYSTEM, OR FREE FROM LOSS OR CORRUPTION OF DATA. KLACKEY DOES NOT WARRANT THAT ANY DEFECT, SECURITY ISSUE, OR COMPATIBILITY ISSUE WILL BE CORRECTED.

You are responsible for testing the Software, maintaining backups, protecting access to your device, and verifying important output before relying on it.

Some jurisdictions do not allow certain warranty exclusions. In those jurisdictions, the exclusions apply only to the maximum extent permitted by law.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KLACKEY AND ITS MEMBERS, MANAGERS, EMPLOYEES, CONTRACTORS, LICENSORS, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF DATA, CONTENT, PROFITS, REVENUE, BUSINESS, GOODWILL, OR PRODUCTIVITY, ARISING FROM OR RELATED TO THE SOFTWARE OR THIS AGREEMENT, EVEN IF ADVISED THAT SUCH DAMAGES WERE POSSIBLE.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KLACKEY'S TOTAL AGGREGATE LIABILITY ARISING FROM OR RELATED TO THE SOFTWARE OR THIS AGREEMENT WILL NOT EXCEED THE GREATER OF: (A) THE AMOUNT PAID FOR THE APPLICABLE LICENSE; OR (B) US $50.

The limitations in this section apply regardless of the form of action and even if a remedy fails of its essential purpose. They do not apply to liability that cannot lawfully be excluded or limited.

12. Termination

This Agreement remains effective until terminated. Your license terminates if you materially breach this Agreement and fail to cure the breach within 10 days after receiving notice, except that Klackey may terminate immediately for license sharing, circumvention of licensing controls, unlawful redistribution, or infringement of Klackey's intellectual property.

Upon termination, you must stop using and uninstall the Software. Termination does not transfer ownership of your locally stored content to Klackey. Where technically available, you should export your content before uninstalling.

Sections concerning restrictions, ownership, warranties, liability, governing law, and general terms survive termination.

13. Governing Law and Consumer Rights

This Agreement is governed by the laws of the State of California, without regard to conflict-of-law principles.

Nothing in this Agreement deprives a consumer of a mandatory protection provided by the law of the consumer's usual country or state of residence that cannot be waived by contract.

14. Changes to This Agreement

The version of this Agreement accepted when you purchase or activate a license governs that license unless you affirmatively accept a later version.

Klackey may make non-material changes to clarify this Agreement, correct errors, update contact information, or reflect changes in law or service providers. Material changes will apply prospectively and may require renewed acceptance. A new purchase, renewal, or major-version upgrade may be offered under a newer agreement presented before the transaction or activation.

15. General Terms

This Agreement, together with terms presented at purchase and any applicable third-party notices, constitutes the entire agreement between you and Klackey concerning the Software.

If any provision is held unenforceable, it will be enforced to the maximum extent permitted and the remaining provisions will remain effective. A failure to enforce a provision is not a waiver. You may not assign this Agreement or transfer a license without Klackey's written consent. Klackey may assign this Agreement in connection with a merger, acquisition, reorganization, or sale of the Software business.

Headings are for convenience only. The words "including" and "includes" mean "including without limitation."
