Terms of Service
The plain version: You pay 99p a month. We provide the Hyphælium software and vault. Your breadcrumbs are yours. You may not copy or redistribute the software. Either of us can end the arrangement at any time. We are honest about what we can and cannot guarantee.
1. Who we are
Hyphælium is an independent venture operated as a sole trader, based in Burton upon Trent, United Kingdom. References to "Hyphælium", "we", "us" or "our" refer to that operator. References to "you" or "subscriber" refer to the person who has subscribed to the service. Contact: support@hyphaelium.com
2. What the service is
Hyphælium is a browser userscript and associated vault service that allows subscribers to save breadcrumb records of AI conversations across multiple platforms. For each breadcrumb, the service records the platform name, the conversation URL, the opening words of your first message (so you can find the thread again), and a timestamp. It does not store the rest of the conversation, the AI's responses, or anything you typed after that opening message.
The service is provided as described on our website at hyphaelium.com. We reserve the right to add, modify or remove features with reasonable notice.
3. Your subscription
The subscription fee is £0.99 per month, billed monthly through Stripe. Payment is due at the start of each billing period. You may cancel at any time. Cancellation takes effect at the end of the current billing period. We do not offer refunds for partial billing periods, except where required by law.
We reserve the right to change the subscription price with 30 days written notice by email. If you do not wish to continue at the new price, you may cancel before the change takes effect.
4. Your rights to use the service
Subject to these terms and payment of the subscription fee, we grant you a personal, non-exclusive, non-transferable licence to install and use the Hyphælium userscript on your own devices, access and use the vault service, and access the documentation provided. This licence covers Hyphælium only. It does not include, and is not a substitute for, any subscription or account you may need with the AI platforms themselves — those remain your own responsibility. This licence is for personal use only and does not permit commercial redistribution or resale.
5. What you may not do
You agree not to:
- Copy, reproduce, distribute or publicly display any part of the Hyphælium software, design, text or documentation without our written permission
- Reverse engineer, decompile or attempt to extract the source code of the software
- Modify or create derivative works based on the software or any associated material
- Use the service in any way that violates applicable law or the terms of the AI platforms you use alongside it
- Share your subscription credentials with others or allow others to use your account
- Use the service for any commercial purpose other than your own personal or professional use
6. Intellectual property
All intellectual property in the Hyphælium service — including the software, the Forward manifesto, the visual design, the brand name, the hyphal icon, and all associated documentation — belongs to us and is protected by copyright and, where registered, trademark law.
The Forward manifesto ("No thought left behind") is an original literary work. It may be shared for personal, non-commercial purposes provided the authorship and source are clearly attributed. It may not be reproduced commercially or incorporated into other works without written permission.
Your breadcrumb data belongs to you. We claim no ownership over it and will never use it for any purpose other than providing the service to you.
7. Your data
We handle your data in accordance with our Privacy Policy. In summary: we store only the minimum data necessary to provide the service — the platform, the conversation link, the opening words of your first message, and a timestamp. We do not store the body of your conversations or the AI's responses, and we do not sell your data. Your breadcrumbs are stored securely against your account, and you have the right to export or delete them at any time by emailing privacy@hyphaelium.com.
8. Service availability
We aim to provide a reliable service but cannot guarantee uninterrupted availability. The service depends on third-party infrastructure — including our hosting, database and payment providers — which is outside our direct control.
Important: Hyphælium works by reading publicly visible elements of AI platform interfaces. When those platforms update their interfaces — which they do regularly and without notice — certain functions may temporarily stop working. We monitor for such changes and aim to issue fixes promptly. This is an inherent characteristic of browser-based software of this kind and does not constitute a failure of service.
9. Limitation of liability
To the fullest extent permitted by law, we are not liable for any loss of data, loss of business, loss of profits or any indirect or consequential losses arising from your use of the service. Our total liability shall not exceed the subscription fees paid by you in the three months preceding the claim. Nothing in these terms limits our liability for death, personal injury, fraud or any liability that cannot be excluded by law.
10. Termination
You may cancel your subscription at any time by emailing us at support@hyphaelium.com. We may suspend or terminate access if you breach these terms, fail to pay, or if we discontinue the service. On termination, you may request an export of your breadcrumb data, and it will be deleted within 30 days of your request.
11. Changes to these terms
We will notify you by email at least 14 days before material changes take effect. Continued use after that date constitutes acceptance of the updated terms.
12. Governing law
These terms are governed by the law of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.
