Your content and data

You own the content you create in Letterly — your emails, your contacts, and your email data. We do not claim any ownership over your content.

We do not sell your data or your contacts' data to anyone. We only use your data to provide and improve the service. See our Privacy Policy for details.

Gmail and Google

Letterly sends emails through your Gmail account using the Gmail API. This means:

Emails are sent from your actual Gmail address and are subject to Gmail's sending limits and policies
You can revoke Letterly's access at any time through your Google Account settings
We do not read, access, or store the contents of your Gmail inbox

Prohibited use

You may not use Letterly to:

Send unsolicited bulk email (spam)
Distribute malware, phishing, or deceptive content
Harass, threaten, or abuse others
Violate any applicable laws or regulations
Attempt to access other users' accounts or data
Reverse-engineer, scrape, or misuse the service

We reserve the right to suspend or terminate accounts that violate these terms.

Service availability

We aim to keep Letterly available and reliable, but we cannot guarantee 100% uptime. The service depends on third-party infrastructure (Google, Vercel, Neon) and may experience occasional downtime for maintenance or due to factors beyond our control.

Limitation of liability

Letterly is provided "as is" without warranties of any kind. We are not liable for any indirect, incidental, or consequential damages arising from your use of the service, including but not limited to lost revenue, data loss, or email deliverability issues.

Account termination

You can stop using Letterly at any time by revoking Google access and contacting us to delete your account. We may also terminate or suspend your account if you violate these terms. Upon termination, your data will be deleted.

Changes to these terms

We may update these terms from time to time. If we make significant changes, we will notify you through the application. Continued use of Letterly after changes constitutes acceptance of the updated terms.
