Quillvein

Terms & Conditions

Last updated 21 August 2026

1. Who you are contracting with

Quillvein is owned and operated by Samantha Silva ("Quillvein", "we", "us"), trading as Quillvein. These Terms form the agreement between you and Samantha Silva for your use of the Quillvein writing platform at quillvein.com and any related services.

2. Acceptance

By creating an account, subscribing, or continuing to use Quillvein you agree to these Terms. If you do not agree, stop using the service. If you are using Quillvein on behalf of an organisation you confirm you have authority to bind it; if you are using it as an individual you confirm you are of legal age to enter a contract.

3. What Quillvein provides

Quillvein is a subscription writing workspace: manuscript drafting, dictation, story bible and canon tools, plot mapping, AI assistance (continuity checks, image drafting, companion guidance), inspiration boards and export tools. Features may change, improve or be retired over time.

4. Your account

You must give accurate registration information and keep it current. You are responsible for keeping your credentials confidential and for all activity under your account. Tell us promptly if you suspect unauthorised access.

5. Licence and restrictions

We grant you a limited, non-exclusive, non-transferable right to use Quillvein within the plan you have selected. You may not reverse engineer, resell, redistribute, sublicense or circumvent technical limits of the service.

6. Acceptable use

You must not misuse Quillvein. In particular, you must not:

  • use the service for anything unlawful, or in breach of any applicable regulation;
  • commit fraud, send spam, or impersonate another person;
  • infringe anyone's intellectual property, publicity or privacy rights, including by uploading text or images you do not have the rights to;
  • interfere with the security or integrity of the service — no malware, probing, scraping, automated bulk access, or attempts to access another user's work.

7. Your content

Your manuscripts, notes, characters, uploads and generated assets remain yours. You grant us only the limited licence needed to host, store, process and display that content in order to run the service for you (including sending relevant excerpts to our AI providers when you invoke an AI feature). We do not use your writing to train models and we do not sell it.

8. AI features and your responsibilities

Quillvein includes generative AI (companion guidance, continuity analysis, character and location image drafting, marketing suggestions). You are responsible for your prompts, for how you use the outputs, for verifying accuracy, and for holding the rights to any content you feed in.

  • Prohibited AI use: no illegal content, sexual content involving minors, deepfakes or misleading depictions of real people, hate speech, harassment, malware, or attempts to jailbreak or circumvent safety filters.
  • Inputs and outputs: you keep rights in your inputs; as between you and us, outputs generated from your inputs are yours to use, subject to these Terms and to third-party rights. Outputs are not guaranteed to be unique.
  • Takedown: rights-holders can contact us at quillveinadmin@gmail.com with details of allegedly infringing content and we will investigate and remove content where appropriate. Repeat infringers will lose access.
  • Moderation: we may remove or restrict content, refuse or filter outputs, and suspend accounts where these Terms are breached.
  • Accuracy: AI outputs may be inaccurate, incomplete or invented. They are not legal, financial, medical or other regulated professional advice, and the wellbeing prompts (breaks, water, rest) are general encouragement, not medical advice.

9. Payment and subscription terms

Quillvein is sold as a monthly subscription (currently $9.99/month, with a 30-day trial for eligible new accounts, and founder places offering 12 months free where offered). Subscriptions renew automatically each billing period until cancelled, and you can cancel at any time from the settings menu inside the app.

Payment, billing, currency, tax, invoicing, cancellation and refund mechanics are handled by our reseller Paddle and are governed by the Paddle Buyer Terms. Our own refund commitment is set out in our Refund Policy.

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

10. Intellectual property

We retain all rights in Quillvein itself — the software, interface, documentation, branding and underlying systems. Nothing in these Terms transfers our IP to you.

11. Service level

We work hard to keep Quillvein available and your work safe, but we do not guarantee that the service will be uninterrupted, error-free, or free of data loss. Export your work regularly using the built-in export tools.

12. Suspension and termination

We may suspend or terminate your access for material breach of these Terms, non-payment, security or fraud risk, or repeated or serious policy violations. You may cancel at any time. When access ends, your stored work is not immediately deleted — you can request an export window by contacting us — but you should export before cancelling. You can delete all your data yourself from the settings menu.

13. Warranties and liability

To the fullest extent permitted by law we disclaim all implied warranties, including merchantability and fitness for a particular purpose. We are not liable for indirect, consequential or special damages, including loss of profits, data or goodwill. Our aggregate liability is limited to the fees you paid in the 12 months before the claim. Nothing here excludes liability for fraud, death or personal injury caused by negligence, or anything else that cannot be excluded by law.

14. Indemnity

You will indemnify us against claims arising from your content, your unlawful use of the service, or your breach of these Terms.

15. General

These Terms are governed by the laws of the seller's jurisdiction, and disputes will be heard by the courts of that jurisdiction. You may not assign this agreement without our consent; we may assign it in connection with a merger or acquisition. Neither party is liable for delays caused by events beyond reasonable control. If a clause is unenforceable, the rest stands.
