Terms of service · Sent in Stone

Last updated: November 12, 2026

1. Who we are

Sent in Stone is provided by Semicognito. When you use Sent in Stone, you're contracting with Semicognito ("we", "us").

Mailing address: Semicognito, Av. Engenheiro Luís Carlos Berrini, 1748 - Conjunto 1710, HR: 121861 - Cidade Monções, São Paulo - SP, 04571-000, Brazil

By installing or using Sent in Stone, you agree to these terms. If you don't agree, please don't use it.

2. What Sent in Stone is

Sent in Stone is a Gmail add-on and email sending service. You read your email in Gmail; to reply from your own domain address, you use our add-on and compose window, and we deliver the email from your domain and place a copy in your Gmail conversation. It works differently from Gmail's "Send mail as" feature; the differences are listed on our homepage.

To use it, you need a Google account with Gmail, and a domain you control and are entitled to send email from.

3. Orders and payment

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

Payments, renewals, cancellation and taxes are governed by Paddle's buyer terms, which apply to your purchase. In short: Sent in Stone is a subscription, billed monthly or yearly at the prices shown on our pricing page; it renews automatically until you cancel; and you can cancel at any time.

Refunds are described in our refund policy.

4. Acceptable use

Sent in Stone is for person-to-person email: messages you write yourself, to people who would expect to hear from you. You agree not to use it:

to send bulk mail, newsletters, marketing campaigns or spam;
to send from a domain or address you aren't entitled to use, or to impersonate anyone;
to send anything unlawful, fraudulent or harmful, including phishing and malware;
to get around our sending limits or interfere with the service.

Sending limits may apply to each account, similar to Gmail's own limit of 500 emails a day.

Email delivery depends on a shared reputation. We monitor bounces and spam complaints reported by our delivery provider, and we may pause or close an account to protect deliverability for everyone. Where we reasonably can, we'll tell you first and give you the chance to put things right. [CONFIRM: how bounces and complaints are actually handled, for the Amazon SES review]

5. What the service depends on

Sent in Stone depends on Google's Gmail and Google Drive platforms, and on email providers that we don't control. If they change, Sent in Stone may have to change, may lose features, or may stop working. Sent in Stone is an independent product. It isn't affiliated with, endorsed by or sponsored by Google.

We can't guarantee that every email reaches its recipient's inbox: delivery also depends on your domain's settings and on the receiving provider.

6. Your email and your data

Your email is yours. We handle it only to provide the service, as described in our privacy policy. You're responsible for what you send.

7. No warranty

We work to keep Sent in Stone reliable, but it's provided "as is" and "as available". To the extent the law allows, we give no warranties beyond those the law requires, including any implied warranties of merchantability, fitness for a particular purpose and non-infringement.

8. Limitation of liability

To the extent the law allows, we aren't liable for indirect, incidental or consequential losses, or for lost profits, revenue, data or business, arising from your use of Sent in Stone. Our total liability for any claim is limited to the amount you paid for Sent in Stone in the twelve months before the claim arose.

Nothing in these terms limits liability that can't be limited by law, or takes away rights you have as a consumer.

9. Ending the agreement

You can stop at any time by cancelling your subscription and uninstalling the add-on. Our support page explains how.

We can suspend or end your access if you break these terms, if your use puts the service or other customers at risk, or if we stop offering Sent in Stone. If we stop offering it, we'll give you reasonable notice and refund any period you've paid for and can't use.

Your data when you leave. Uninstalling the add-on removes the hidden app folder in your Google Drive, including your drafts. The copies of emails you sent stay in your Gmail; they're yours. We delete your account data when you ask us to, and otherwise after your account has been closed for [CONFIRM: how long account data and delivery records are kept after an account closes]. We may keep what the law requires us to keep, such as records of transactions.

10. Changes to these terms

We may update these terms. If a change is significant, we'll tell you by email or inside the product before it takes effect. If you keep using Sent in Stone after a change takes effect, you accept the new terms.

11. Governing law

These terms are governed by the laws of Brazil. If you're a consumer, you keep any mandatory protections of the consumer law of the country where you live; nothing in these terms takes them away.

Purchases are governed by Paddle's buyer terms.
