The fine print, kept short.

Terms of service

The service

Plume (plume-ai.org) rewrites text you provide into a chosen human voice and checks the result against your original. It is provided as is; we work hard on quality but do not guarantee any particular result on any third-party AI detector, grade, or outcome.

Your account

You must be at least 16 years old. Keep your credentials private; you are responsible for activity under your account. One person per account.

Acceptable use

• You keep all rights to the text you submit and to the rewrite you receive.
• You are responsible for how you use the output, including compliance with the rules of your school, employer or publisher, and with applicable law.
• Do not submit text you have no right to use, and do not use Plume to produce unlawful, defamatory or fraudulent content.
• Do not attempt to overload, reverse engineer or resell the service without written permission.

Plans and billing

Free accounts get a monthly word allowance. Paid plans (Premium, Unlimited) are monthly subscriptions billed in euro through Stripe and renew automatically until cancelled. You can cancel at any time from your account page; access continues until the end of the paid period. Prices may change with at least 14 days' notice by email.

Availability and changes

We may change features, voices and limits, and may suspend accounts that break these terms. We are not liable for indirect damages; our total liability is limited to the fees you paid in the last three months.

Privacy policy

What we collect

• Account data: email address, a password hash (or your Google account id if you sign in with Google), plan and usage counters.
• Your texts: the text you submit and the rewrite we produce, stored only to deliver the result and deleted automatically 7 days after the job finishes.
• Technical data: IP address and request logs for security and rate limiting, kept for up to 30 days.
• Payments: handled entirely by Stripe. We store your Stripe customer id and plan; we never see your card number.

How texts are processed

Rewriting runs on our own servers. For fact checking and editor's marks, passages of your text are sent to OpenAI's API under a zero-retention business agreement; they are not used to train models. We do not train any model on your texts. We do not sell or share personal data with advertisers.

Cookies

One session cookie keeps you signed in. Our pages also load the Google tag (Google Ads), which sets cookies to measure whether an ad visit led to a sign-up or purchase; it does not receive the content of your texts. You can block it with any content blocker without affecting the service.

Your rights

You can delete your account and all associated data yourself from the account page at any time. Under the GDPR you may also request access, correction or export of your data by emailing [email protected]. Data is stored in the EU.

Refund policy

If Plume is not for you, email us within 7 days of your first payment and we will refund it in full, no questions asked. Renewals are not refunded, but you can cancel at any time and keep access until the end of the period. If the service was unavailable for a significant part of your billing period, ask us and we will credit or refund the affected time.
