Terms of service

1. Who we are

Charles is a service of [RAZÓN SOCIAL], tax ID [CIF], registered at [DIRECCIÓN, CÓDIGO POSTAL, CIUDAD, PAÍS]. Contact: privacidad@usecharles.com.

2. What the service does

Charles imports your quotes, drafts follow-ups and replies, and sends them once you approve them. It also classifies your customers' replies to help you prioritise.

Charles never sends email on its own. Every message that goes out has been reviewed and approved by someone on your team.

3. Your account

You need an account and you are responsible for activity under it. Whoever creates the company is the owner: only they can invite the team, connect the CRM and manage the subscription.

4. Acceptable use

You agree to write only to contacts with whom you have a prior business relationship and a lawful basis to contact. Using the service with purchased lists, for unsolicited bulk email, or for unlawful or deceptive content is prohibited.

Remember that emails leave from your own Gmail account. Misuse damages your domain's reputation before ours, and can lead Google to restrict your account.

We may suspend the service if we detect use that breaches this section.

5. Usage limits

The service applies the following limits, meant to prevent abuse rather than to restrict normal work:

• Free trial: 50 follow-ups during the first 14 days.
• Without a subscription once the trial ends: 3 follow-ups every 3 days per company.
• With a subscription: 20 follow-ups every 3 days per salesperson with a connected mailbox.
• A single draft can be rewritten by the AI up to 5 times.
• Replying to a customer who wrote to you is never limited.

6. Price and billing

The subscription is charged per salesperson with a connected mailbox, monthly and in advance, through Stripe. If someone connects or disconnects during the period, Stripe prorates the difference automatically.

You can cancel at any time from the billing portal. Cancellation takes effect at the end of the period already paid, which is not refunded pro rata.

If a charge fails we keep the service running while Stripe retries. If it ultimately fails, the account returns to the free plan.

7. Your data and content

The data you upload remains yours. We handle it under the privacy policy and only to provide the service.

You are responsible for the content you send, including AI-generated drafts you choose to approve. Review them before sending.

8. Availability and warranties

We work to keep the service available, but we do not guarantee uninterrupted or error-free operation. We depend on third parties such as Google, Stripe and the AI providers, whose incidents can affect the service.

Charles guarantees no particular commercial outcome: whether a customer replies or accepts a quote is not within our control.

9. Liability

To the extent permitted by law, our total liability to you is limited to the amount you paid for the service in the twelve months before the event giving rise to it. We are not liable for lost profits or indirect damages.

10. Cancellation and termination

You may stop using the service and request deletion of your account at any time. We may terminate the agreement if you breach these terms, giving you notice unless the severity requires acting immediately.

11. Governing law

These terms are governed by Spanish law. Last updated: 2026-09-04.
