Terms of service
Last updated November 11, 2026. Version 2026-11-11.
Click Oracle is a service of LumeGrid ("we", "us"). By creating an account you agree to these terms.
What the service does
Click Oracle predicts which of your text options people are more likely to click or open, and can write options with Claude. Predictions are estimates based on past real-world tests. They are not guarantees of any result, and we are not liable for decisions you make with them. The evidence page describes how accurate the predictions were on held-out data and where they were not measured.
Your account
- You must be 18 or older and give a valid email address. Keep your password and API keys private; you are responsible for use of your account and keys.
- One person per account. Agency plans may be used for many clients by the account holder's team, sharing one login, until team seats are offered.
Acceptable use
Do not use Click Oracle to write or optimize spam or unsolicited messages, phishing, scams, deceptive or misleading claims, content that impersonates others, content that hides that it was made with AI where that is required, illegal content, or content that harasses, discriminates or threatens. Do not try to extract, copy or resell the underlying models, run automated benchmarking of them for publication without our written permission, overload the service, or get around limits. We may suspend accounts that break these rules.
Your content
You keep the rights to what you submit and to the options Claude writes for you. You give us permission to process your content to provide the service, as described in the privacy policy. You confirm you have the right to submit it.
Plans, billing and cancellation
- Paid plans renew monthly until canceled. Prices and limits are on the pricing page. Usage resets on the first of each month, Mountain Time; unused usage does not roll over. Upgrading raises your limit right away.
- Plan limits are hard stops: you are never billed more than the plan price plus any sales tax or VAT. Rankings and writing can also pause (HTTP 503) when shared daily or monthly model capacity is reached; that request is not counted against your plan.
- Stripe is the merchant of record for paid plans and collects any applicable sales tax or VAT at checkout. You can cancel any time from your account or by contacting support; the plan stays active until the end of the paid month. If something went wrong on our side, contact support and we will make it right, including a refund where fair, through Stripe's refund process.
- If you cancel or your paid plan ends, we keep your rankings and written options at that paid plan's history window for 30 days so you can export them. After those 30 days, the Free plan's 7-day window applies.
- We will give at least 30 days' notice by email before a price change on your plan.
Availability and changes
We work to keep the service available but do not promise it will be uninterrupted. We may change features; if a change materially reduces a paid plan, you may cancel and receive a prorated refund.
Liability
To the extent the law allows, the service is provided "as is", and our total liability for any claim is limited to the amount you paid us in the 3 months before the claim.
Ending
You may delete your account at any time from Account settings. We may end the service for an account that breaks these terms, with notice where practical.
