Terms of Service

These terms govern your use of Crux. Plain summary first, in case you read nothing else: you keep your content, we never post as you without your approval, either of us can end the arrangement at any time, and you are responsible for what you publish.

1. Who we are and what this covers

Crux (“Crux”, “we”, “us”) provides a subscription tool that scores posting opportunities on X and drafts posts in your voice. These terms cover the website, the application, and any support we provide. By creating an account you accept them.

Crux is an independent product. It is not affiliated with, sponsored by, or endorsed by X Corp.

2. Your account

You need an X account to connect and you must be old enough to hold one under X’s own rules. You are responsible for activity under your account, and for keeping your credentials secure.

• One person or organisation per account. Plans state how many connected X accounts they cover.
• You may not resell access or share a single seat across several people.
• Tell us promptly at hello@cruxpost.com if you believe your account has been accessed by someone else.

3. What you own, and what we do with it

Your posts, your drafts and the voice model derived from them are yours. You grant us only the permission needed to operate the service: to read your public posts, to derive a voice model for your account, to store your drafts, and to display all of it back to you.

We do not claim ownership of anything you write, we do not train a shared or general model on your content, and we do not sell it. You can export everything as a single JSON file at any time.

4. What you are responsible for

Crux produces suggestions and drafts. You decide what gets published, and once published it is your post under X’s rules, not ours.

• Nothing is posted to X without your explicit approval of that specific post.
• You are responsible for the accuracy, legality and originality of what you publish.
• You must not use Crux to produce harassment, impersonation, spam, or content that breaks X’s terms.
• Automated engagement schemes are out of scope for the product and out of bounds under these terms.

5. Fees, the API pass-through, and taxes

Subscription fees are stated on the pricing page, billed monthly in advance, and quoted in USD exclusive of any tax we are required to collect.

• X charges separately for API reads. We pass that cost through without markup, and it is billed to you as metered usage against the monthly cap you set.
• Scanning pauses when your cap is reached. You are never charged for reads above the cap.
• You can change or cancel a plan at any time; access continues to the end of the period you paid for.
• We refund any charge within fourteen days on request, for any reason.

6. Availability and changes to the service

We aim to keep Crux running continuously but we do not promise uninterrupted availability, and parts of the service depend on X’s API remaining accessible on workable terms. If X changes its API in a way that makes a feature impossible, we will say so plainly rather than quietly degrade it.

We may add, change or remove features. If a change materially reduces what you are paying for, we will tell you before it takes effect and you may cancel and take a pro-rata refund.

7. Ending the arrangement

You can cancel at any time from Settings. We may suspend or close an account that breaches these terms, with notice and an explanation except where the breach is serious enough to require immediate action.

After closure your drafts and voice model remain exportable for thirty days, then they are deleted.

8. Liability

Crux is a judgement aid. We are not liable for the reception, reach or consequences of anything you choose to publish, nor for losses arising from decisions you make on the strength of a score.

To the extent the law allows, our total liability for any claim relating to the service is limited to the subscription fees you paid us in the twelve months before the claim. Nothing here limits liability that cannot lawfully be limited.

9. Changes to these terms

We will post any change here with a new “last updated” date, and will email account holders at least thirty days before a material change takes effect. Continuing to use Crux after that date means you accept the change.
