By installing or using Quillhollow ("the Software"), you agree to be bound by the terms of this agreement between you and Wilson Technical Arts Inc. ("Wilson Technical Arts"). If you do not agree, do not install or use the Software.

For questions, support, or license inquiries, contact support@quillhollow.app or visit https://quillhollow.app.

1. DEFINITIONS

As used in this agreement:

"Software" means the Quillhollow application and all associated files distributed by Wilson Technical Arts.

"License Key" means the randomly generated opaque identifier issued by Wilson Technical Arts upon purchase, used to unlock the Software's advanced features after the trial period. License Keys do not contain or encode any personal information.

"Order ID" means the opaque transaction identifier assigned by our payment processor (Paddle.com Inc.) at the time of purchase and included in your purchase confirmation. The Order ID is used by Wilson Technical Arts solely to issue and, if necessary, recover your License Key.

"Major Version" means the whole number preceding the decimal point in the Software's version number. For example, versions 1.0, 1.1, and 1.9 are all part of Major Version 1, while version 2.0 begins Major Version 2.

"You" and "your" refer to the individual accepting this agreement.

2. LICENSE GRANT

In plain terms: you can install and use Quillhollow on as many of your own computers as you like, including for professional and commercial work.

Wilson Technical Arts grants you a limited, non-exclusive, perpetual license to install and use the Software on any number of computers owned or controlled by you, for personal, professional, or commercial use, subject to the terms of this agreement. The Software currently supports Windows 10 and Windows 11. Wilson Technical Arts does not guarantee support for Windows versions released before or after these versions, or for versions that Microsoft has declared end-of-life. The applicable platform requirements for your version of the Software are described in the release notes accompanying that version. Support for additional platforms may be introduced in future versions of the Software.

3. LICENSE TRANSFER

In plain terms: you can give your license to someone else, but you must stop using the Software yourself when you do. Pass on your order ID along with the key so the recipient can recover it if needed.

You may transfer your license to another person by providing them with your License Key and your original order ID, provided that: (a) you permanently cease all use of the Software, (b) you remove all copies from your computers, and (c) the recipient agrees to the terms of this agreement. License Keys are opaque identifiers and do not contain or display any personal information about the original purchaser. License transfers are self-managed; Wilson Technical Arts does not operate a transfer tracking system and is not responsible for verifying or facilitating transfers between individuals. Transfer may only occur directly between individuals, not through unauthorized resale marketplaces or key-reselling services, except to the extent required or permitted by applicable law, including rights of resale under the doctrine of software exhaustion where applicable. After transfer, your license is void and you may not continue to use the Software. The recipient of a transferred key may use the original order ID to request key recovery assistance from Wilson Technical Arts at support@quillhollow.app.

4. TRIAL PERIOD

In plain terms: you get 30 days to try everything before buying - but only days you actually use the Software count down, so you can take breaks. Core writing features stay available after the trial ends.

The Software includes a free trial period of thirty (30) days of use. A day of use is counted each calendar day on which you launch and use the Software; days on which the Software is not used do not count toward the trial. The thirty days do not need to be consecutive. During the trial, all features are available. When the trial expires, core features (writing and exporting) remain functional, but advanced features (Plan and Outline views) require a valid License Key to access. If you believe the trial counter has not accurately reflected your days of use, please contact support@quillhollow.app for assistance. Please use the trial period to evaluate the Software before purchasing.

5. REFUND POLICY

In plain terms: you have 30 days from purchase to request a refund, no questions asked.

Purchases may be refunded within thirty (30) days of the original purchase date. To request a refund, contact our payment processor (Paddle.com Inc.) directly or reach us at support@quillhollow.app. Refund requests submitted after thirty (30) days of the original purchase date will not be accepted. If you are located in the European Union, the United Kingdom, Australia, Canada, or another jurisdiction that grants statutory cancellation or refund rights for digital goods that exceed this window, those rights apply and are not limited by this agreement.

6. LICENSE KEY

In plain terms: your License Key is a random code - it contains no personal information. No internet connection is needed to activate or use the Software. If you lose your key, you can recover it by contacting support with your order ID from your purchase receipt.

A License Key is required after the trial period to access advanced features. License Keys are randomly generated opaque identifiers issued by Wilson Technical Arts at the time of purchase; they do not contain or encode any personal information. No internet connection is required to activate or use the Software; license activation is performed locally on your machine. You may not share your License Key with others while retaining use of the Software yourself.

Because the Software operates entirely offline, Wilson Technical Arts cannot remotely deactivate a License Key. However, Wilson Technical Arts reserves the right to revoke a License Key obtained through fraud or in violation of this agreement, and to pursue available legal remedies - including cease-and-desist letters, removal requests against unauthorized resellers, and civil action - where appropriate. Wilson Technical Arts will act in good faith and will only revoke a License Key where there is clear evidence of fraud or material violation. A License Key that has been revoked under this section is no longer a valid license, and continued use of the Software under such a key constitutes a violation of this agreement.

You are responsible for safeguarding your License Key. If you lose your License Key, you may contact support@quillhollow.app for assistance. To verify ownership and recover your key, you will need to provide your order ID, which is included in the purchase confirmation sent to you at the time of purchase. While we will make reasonable efforts to help, recovery cannot be guaranteed.

7. UPDATES AND SUPPORT

In plain terms: updates within the version you purchased are free. We may charge for future Major Version upgrades, but your current version will keep working if you choose not to upgrade.

Wilson Technical Arts may release updates to the Software at its sole discretion. No guarantee is made that updates, patches, or new features will be provided. Any updates released within the current Major Version of the Software will be made available to licensed users at no additional charge. Wilson Technical Arts reserves the right to charge for future Major Version upgrades. Your licensed version of the Software will continue to function if you choose not to purchase a future Major Version upgrade; you will simply not receive new features or updates introduced in that Major Version.

Support is provided on a best-effort basis through support@quillhollow.app or https://quillhollow.app. Wilson Technical Arts does not guarantee response times or resolution of any particular issue. Support availability may change at any time without notice.

8. RESTRICTIONS

In plain terms: please don't copy, crack, or redistribute the Software. Your writing, however, is entirely yours to use however you like.

You may not:

  • Copy, modify, or distribute the Software except as permitted by this agreement
  • Reverse engineer, decompile, or disassemble the Software
  • Rent, lease, or sublicense the Software to third parties
  • Remove or alter any copyright notices, trademarks, or other proprietary notices
  • Circumvent or attempt to circumvent the license verification system
  • Use the Software for any unlawful purpose or in violation of any applicable law or regulation

Notwithstanding the above, nothing in this section is intended to limit any right you may have under applicable law to decompile or otherwise access the Software solely to the extent necessary to achieve interoperability with independently created software, provided you have first requested the necessary information from Wilson Technical Arts and we have not provided it within a reasonable time.

These restrictions apply to the Software only, not to content you create using the Software. You are free to use your writing and exported files with any third-party tools or services, including artificial intelligence tools, at your own discretion.

9. OWNERSHIP

In plain terms: Wilson Technical Arts owns the Software; you own a license to use it.

The Software is licensed, not sold. Wilson Technical Arts retains all rights, title, and interest in and to the Software, including all intellectual property rights.

10. YOUR CONTENT

In plain terms: everything you write is yours. We don't want it, see it, or touch it.

You retain full ownership of all content you create using the Software. Wilson Technical Arts makes no claim to your writing, projects, or exported files. No content you create is transmitted to Wilson Technical Arts or any third party.

11. DATA AND PRIVACY

In plain terms: Quillhollow is entirely local. Nothing you write or do in the Software leaves your computer during normal use. The Software has no automatic crash reporting; bug reports are only sent if you manually choose to contact support. When you check for updates or send a bug report, your app version, OS platform, OS version, and Electron version may be included. Your IP address may be recorded in standard web server logs by our hosting provider as part of normal infrastructure operation - we do not actively collect, store, or associate it with your identity or purchase.

The Software operates entirely on your local machine and does not require an internet connection to install, activate, or use. No data is collected, transmitted, or shared with external servers during normal use. No analytics, telemetry, or usage tracking is performed. The Software does not include automatic crash or error reporting; any bug reports are sent only when you manually choose to contact support. Your project files are stored locally on your computer. When you manually check for updates or submit a bug report, your application version, operating system platform, operating system version, and Electron runtime version may be included in the request. Your IP address may be recorded in standard web server logs by Wilson Technical Arts' hosting provider as part of normal infrastructure operation; Wilson Technical Arts does not actively collect, store, or associate your IP address with your identity, license, or any other personal information. For full details, see our Privacy Policy at https://quillhollow.app/privacy.html.

12. ARTIFICIAL INTELLIGENCE

In plain terms: your writing will never be used to train AI, and the Software won't silently feed your work to any AI service. This commitment carries forward to any future owner of Wilson Technical Arts.

Wilson Technical Arts and its successors and assigns will never use content you create with the Software for AI model training or any other machine learning purpose. The Software does not transmit your content to any AI service or third party. The Software does not incorporate AI-generated content into your work without your explicit action.

13. BACKUPS

In plain terms: the Software includes automatic local backups, but please keep your own copies of anything important.

The Software includes automatic local backup functionality designed to help protect your work against unexpected data loss. All backups are stored locally on your computer; nothing is sent to any external server or cloud service. You may configure additional backup locations, such as an external drive, for further redundancy.

These backups are provided on a best-effort basis. Wilson Technical Arts does not guarantee the availability or integrity of backup files. You should not rely solely on the Software's backup functionality to protect important work. You are responsible for maintaining your own independent backups of any content you cannot afford to lose.

14. EXPORTED FILES

In plain terms: we do our best to make exports compatible with common tools, but can't guarantee compatibility with every version of every third-party application. Exported files are yours.

The Software can export your content to third-party file formats (e.g., Microsoft Word .docx). Wilson Technical Arts will make best efforts to ensure compatibility with common third-party formats but cannot guarantee compatibility with all versions of third-party software. Exported files are your property.

15. DISCLAIMER OF WARRANTIES

In plain terms: we stand behind Quillhollow, but we cannot make legal guarantees about software behavior. That's what the free trial is for - please use it to evaluate the Software before purchasing.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE SOFTWARE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT. WILSON TECHNICAL ARTS DOES NOT WARRANT THAT THE SOFTWARE WILL BE ERROR-FREE OR UNINTERRUPTED.

16. LIMITATION OF LIABILITY

In plain terms: if you experience a loss related to the Software, the most we can be held responsible for is the amount you paid for it. We are not liable for indirect losses such as lost work or lost income.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL WILSON TECHNICAL ARTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO YOUR USE OF THE SOFTWARE, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, LOSS OF PROFITS, OR BUSINESS INTERRUPTION, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IN NO EVENT SHALL THE TOTAL LIABILITY OF WILSON TECHNICAL ARTS EXCEED THE AMOUNT PAID BY YOU FOR THE SOFTWARE.

17. INDEMNIFICATION

In plain terms: if your misuse of the Software causes legal trouble for Wilson Technical Arts, you're responsible for those costs - but your liability is capped at the same amount as ours.

You agree to indemnify, defend, and hold harmless Wilson Technical Arts and its officers, employees, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising out of or related to: (a) your use of the Software in violation of this agreement; or (b) your violation of any applicable law or regulation in connection with your use of the Software; provided, however, that your total liability under this section shall not exceed the amount paid by you for the Software. Wilson Technical Arts will promptly notify you of any such claim and will cooperate reasonably in its defense.

18. TERMINATION

In plain terms: your license lasts as long as you follow this agreement. If you materially breach it and don't remedy the problem, Wilson Technical Arts can terminate your license - but your content and exported files are always yours regardless.

This license is effective until terminated. Wilson Technical Arts may terminate this license upon written notice if you materially breach any term of this agreement and fail to cure such breach within thirty (30) days of receiving written notice describing the breach. A material breach includes, but is not limited to, any violation of Section 8 (Restrictions) of this agreement. For breaches that are incapable of being cured, Wilson Technical Arts may terminate immediately upon written notice. Upon termination, you must destroy all copies of the Software. Your content and exported files remain your property regardless of termination.

19. GOVERNING LAW AND DISPUTES

In plain terms: disputes are governed by Ontario law. We'd like to work things out directly before either party pursues formal legal action.

This agreement shall be governed by and construed in accordance with the laws of the Province of Ontario, Canada, without regard to its conflict of law provisions. Any dispute arising under this agreement shall first be addressed through good-faith negotiation by contacting Wilson Technical Arts at support@quillhollow.app, allowing at least thirty (30) days for resolution, before either party pursues formal legal action. Any dispute not resolved through negotiation shall be submitted to the exclusive jurisdiction of the courts of the Province of Ontario, Canada.

Wilson Technical Arts and you both prefer that disputes be resolved individually rather than through class proceedings. Accordingly, to the extent permitted by applicable law, you agree to bring any dispute in your individual capacity and not as a plaintiff or class member in any purported class action, collective action, or representative proceeding. You acknowledge that in Ontario and certain other jurisdictions, class action waivers may not be fully enforceable; nothing in this agreement is intended to limit any rights you have under applicable law, including the right to participate in a class proceeding where such rights cannot lawfully be waived.

Nothing in this agreement is intended to limit any rights you may have under the consumer protection or data protection laws of your jurisdiction. If you are located in the European Union, the United Kingdom, Australia, or another jurisdiction with mandatory consumer protections, those protections apply in addition to the terms of this agreement.

20. EUROPEAN UNION - DATA PROTECTION

The Software does not collect, process, or transmit personal data as part of its normal operation, as described in Section 11. When you voluntarily interact with Wilson Technical Arts' website or support infrastructure (such as checking for updates or submitting a bug report), your IP address may be recorded in standard web server logs by Wilson Technical Arts' hosting provider as part of its normal infrastructure operation. Wilson Technical Arts does not actively collect, process, or associate this data with your identity. To the extent this incidental logging constitutes processing of personal data under the GDPR, Wilson Technical Arts acts as data controller and relies on the legitimate interest of maintaining secure and functional web infrastructure as its legal basis under Article 6(1)(f). For information about data handling in connection with license purchases, see our Privacy Policy at https://quillhollow.app/privacy.html. If you believe that any personal data has been processed contrary to this agreement, you have the right to contact Wilson Technical Arts at support@quillhollow.app and, if necessary, to lodge a complaint with the data protection authority in your jurisdiction.

21. UNITED KINGDOM - DATA PROTECTION

The Software does not collect, process, or transmit personal data as part of its normal operation, as described in Section 11. When you voluntarily interact with Wilson Technical Arts' website or support infrastructure (such as checking for updates or submitting a bug report), your IP address may be recorded in standard web server logs by Wilson Technical Arts' hosting provider as part of its normal infrastructure operation. Wilson Technical Arts does not actively collect, process, or associate this data with your identity. To the extent this incidental logging constitutes processing of personal data under the UK GDPR or the Data Protection Act 2018, Wilson Technical Arts acts as data controller and relies on the legitimate interest of maintaining secure and functional web infrastructure as its legal basis. For information about data handling in connection with license purchases, see our Privacy Policy at https://quillhollow.app/privacy.html. If you believe that any personal data has been processed contrary to this agreement, you have the right to contact Wilson Technical Arts at support@quillhollow.app and, if necessary, to lodge a complaint with the Information Commissioner's Office (ICO) or the data protection authority in your jurisdiction.

22. AUSTRALIA - CONSUMER GUARANTEES

If you are located in Australia, the Australian Consumer Law (ACL) provides guarantees that cannot be excluded. Nothing in this agreement excludes, restricts, or modifies any right or remedy you have under the ACL. Where liability can be limited under the ACL, Wilson Technical Arts limits its liability to re-supply of the Software or payment of the cost of having the Software re-supplied.

23. CALIFORNIA - PRIVACY

The Software does not collect or sell personal information as part of its normal operation, as described in Section 11. Accordingly, Wilson Technical Arts does not sell your personal information and has no obligation to provide a "Do Not Sell" mechanism with respect to the Software's operation. If you believe your personal information has been handled contrary to this agreement, you may contact Wilson Technical Arts at support@quillhollow.app.

24. MINORS

In plain terms: you need to be an adult to buy the Software, but minors can use it if an adult purchases it for them.

By purchasing a license for the Software, you represent that you are at least 18 years of age or the age of majority in your jurisdiction, whichever is greater. This age requirement applies to the purchase of a license only; it does not prohibit use of the Software by persons under that age, provided the license was validly purchased by someone who meets the age requirement above. If you are purchasing a license on behalf of a minor, you accept responsibility for ensuring that minor's use of the Software complies with this agreement.

25. SEVERABILITY

If any provision of this agreement is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.

26. NO WAIVER

In plain terms: if we don't enforce a rule once, that doesn't mean we've given it up.

Failure by Wilson Technical Arts to enforce any provision of this agreement at any time shall not be construed as a waiver of that provision or of the right to enforce it in the future. No waiver of any breach shall be deemed a waiver of any subsequent breach of the same or any other provision.

27. EXPORT CONTROLS

In plain terms: please don't purchase or use the Software if you're located in a country subject to Canadian trade sanctions.

You represent that you are not located in, or a national or resident of, any country or territory subject to sanctions administered by Global Affairs Canada, the Government of Canada, or any other applicable authority, and that you are not a person or entity named on any applicable sanctions or restricted-party list. You agree not to use, export, re-export, or transfer the Software in violation of any applicable Canadian, international, or local export control laws or regulations.

28. FORCE MAJEURE

In plain terms: if something genuinely beyond our control prevents us from providing website access or support services, we're not in breach of this agreement. The Software itself continues to work regardless.

Wilson Technical Arts shall not be liable for any delay or failure in providing website access, update availability, or support services to the extent that such delay or failure is caused by circumstances beyond its reasonable control, including but not limited to natural disasters, acts of government, telecommunications or infrastructure outages, or third-party service failures. This section does not affect the offline functionality of the Software itself, which operates independently of any external services.

29. THIRD-PARTY SOFTWARE AND FONTS

Full license texts for these components are included in that file. Use of these components is governed by their respective licenses, not by this agreement.

30. ASSIGNMENT, ACQUISITION, AND DISCONTINUATION

In plain terms: if Wilson Technical Arts is acquired, your license carries over unchanged. If Wilson Technical Arts ceases operations entirely, your license is unaffected - the Software will continue to work on your machine.

You may not assign or transfer your rights or obligations under this agreement except as described in Section 3 (License Transfer). Wilson Technical Arts may assign this agreement in connection with a merger, acquisition, or sale of all or substantially all of its assets, provided that: (a) the acquiring party assumes all obligations under this agreement in writing; (b) the terms of this agreement continue to govern all existing licenses without modification; and (c) Wilson Technical Arts will provide at least thirty (30) days advance notice to users, such as through an in-app notification or post on https://quillhollow.app. Your License Key will continue to function regardless of any change in ownership or operational status of Wilson Technical Arts.

In the event that Wilson Technical Arts discontinues the Software or ceases operations, your license continues in perpetuity and is not affected. Because the Software operates entirely offline, it will continue to function on your machine regardless of the operational status of Wilson Technical Arts.

31. FEEDBACK AND SUGGESTIONS

In plain terms: if you voluntarily send us ideas or bug reports, we may use them to improve the Software. This never applies to content you create with the Software.

If you submit feedback, bug reports, feature requests, or other suggestions to Wilson Technical Arts (collectively, "Feedback"), you grant Wilson Technical Arts a perpetual, irrevocable, worldwide, royalty-free license to use, reproduce, and incorporate that Feedback into the Software or other products and services, without any obligation of compensation, attribution, or confidentiality to you. You represent that any Feedback you submit is your own and that you have the right to grant this license. This section does not apply to content you create using the Software, which remains governed by Section 10.

32. ENTIRE AGREEMENT

This agreement (Version 1.1) constitutes the entire agreement between you and Wilson Technical Arts regarding the Software and supersedes all prior agreements and understandings. This agreement is made in the English language, and the English language version shall govern in the event of any conflict with a translated version. The current version of this agreement is published at https://quillhollow.app/terms.html. Wilson Technical Arts reserves the right to update this agreement for future versions of the Software. Any such updates apply only to new purchases made after the updated agreement takes effect; customers who purchased a license under a prior version of this agreement continue to be governed by the terms in effect at the time of their purchase. Wilson Technical Arts will provide at least thirty (30) days' notice of material changes, such as through an in-app notification on first launch following an update. Notice is provided as a courtesy; such changes do not affect licenses purchased prior to the updated agreement taking effect.
