We reserve the right to modify these Terms at any time. We will notify you of material changes by email or by posting a notice on the Service at least thirty (30) days before the changes take effect.

2. Description of Service

StackSplit is an AI-powered copywriting platform that enables users to generate, manage, and export email copy and marketing content. The Service includes AI-assisted template generation, campaign and sequence building, workspace management, content export functionality, and analytics dashboards.

The Service is a content generation tool only. StackSplit does not send emails, manage contact lists, or handle recipient data on your behalf. The Service does not transmit, deliver, or route any communications to any third party. Any use of generated content for outbound communications is your sole responsibility and must comply with all applicable laws.

3. Account Registration and Security

To use the Service, you must create an account by providing accurate and complete information, including your name and email address. You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account.

You agree to notify us immediately of any unauthorized access to or use of your account. We are not liable for any loss or damage arising from your failure to protect your account credentials.

You may not share your account with others, create multiple accounts, or transfer your account to another party without our prior written consent.

4. Subscription and Payment

The Service is available on a paid subscription basis at $19.00 per month ("Subscription Fee"). There is no free tier. Your subscription begins upon successful payment and renews automatically each month on the anniversary of your initial payment date.

All payments are processed through Stripe, our third-party payment processor. By subscribing, you authorize us to charge your designated payment method on a recurring monthly basis. You are responsible for keeping your payment information current.

No Refunds. All Subscription Fees are non-refundable. When you cancel your subscription, you will retain access to the Service for the remainder of your current billing cycle. No partial or prorated refunds will be issued for any reason, including early cancellation, account termination, or dissatisfaction with the Service.

If a pricing change increases your Subscription Fee, you may cancel your subscription before the new pricing takes effect. If you do not cancel before the new pricing date, you will be deemed to have accepted the new pricing.

We may add, modify, or discontinue any feature of the Service at our sole discretion. While we will endeavor to provide advance notice for material changes, we are not obligated to maintain any specific feature indefinitely.

6. Usage Limits and Fair Use

Your subscription includes a monthly AI generation allowance equivalent to approximately $10.00 of AI processing costs ("Usage Allowance"). This limit is applied automatically and is designed to ensure fair use of shared AI infrastructure.

If you reach your Usage Allowance, AI generation features will be restricted until your next billing cycle begins, or until you request and are granted an increased limit. To request increased limits, contact us at the support channels provided within the Service.

We reserve the right to adjust the Usage Allowance at any time. Material changes to the Usage Allowance will be communicated to you in advance. Granting of increased limits is at our sole discretion and may be subject to additional fees.
