Privacy Policy

This Privacy Policy explains how Nimbus Labs (“we”, “us”, or “our”) collects, uses, and shares information when you use Retone at retoneai.net (the “Service”).

1. Information We Collect

We collect the following categories of information:

• Submitted text. The text you paste or type into Retone so we can generate a rewrite.
• Usage data. Technical and operational information such as IP address, timestamps, rewrite counts, subscription status, and similar data needed to operate rate limits, security, and the Service.
• Payment data. If you subscribe to Retone Pro, payment is handled by our payment processor. We never store your card numbers. We may receive limited billing metadata (for example, that a subscription is active) so we can provide Pro access.

2. How Text Is Processed

When you request a rewrite, the text you submit is sent to the Anthropic API to generate the rewritten output. We use that text to provide the Service, not to train our own models. We do not use your submitted text to train models. Processing by Anthropic is subject to Anthropic’s own terms and policies.

3. Cookies

We use cookies (and similar technologies) as needed to operate the Service, including to keep session and subscription status so we can recognize Retone Pro access and related preferences. These cookies are used for core functionality rather than advertising.

4. Data Retention

We retain information only as long as needed to provide the Service, enforce rate limits, maintain subscription status, comply with legal obligations, and resolve disputes. Submitted text is processed to generate a rewrite and is not kept as a permanent library of your documents. Usage and subscription records may be kept for a limited period for security, billing, and operational purposes.

5. Your Rights

Depending on applicable law (including Brazilian data-protection law), you may have the right to request access to personal data we hold about you, or to request deletion of that data. To exercise these rights, email viniciussucupira091@gmail.com. We may need to verify your request before fulfilling it.

6. Third-Party Services

We use third-party providers to operate Retone. They process information only as needed to provide their services:

• Vercel — website hosting and related infrastructure
• Upstash Redis — rate limiting and operational data storage
• Payment processor — subscription billing (we never store card numbers)
• Anthropic API — generation of rewritten text

Those providers have their own privacy practices. We encourage you to review them.

7. Changes

We may update this Privacy Policy from time to time. The revised version will be posted on this page with an updated date.
