Subscription & Billing Terms

These Subscription & Billing Terms explain how a customer (the "Customer", "you") pays Neivan Technology Holdings, LLC ("Neivan", "we", "us") for the Synapse platform (the "Service"). They are part of our Terms of Service. All amounts are in US dollars unless an order form says otherwise.

1. Beta: no subscription fee today

Synapse is currently offered as a beta. During the beta:

• no subscription fee is charged, platform features are available without a paid plan, and the number of users is not capped by a plan; and
• AI usage is still paid for as described in Section 3, unless you use your own AI provider keys.

We will give account owners at least 30 days' notice by email before subscription fees start for an existing customer. Nothing is charged for a subscription unless you have agreed to a price — on an order form or at checkout in the Service.

2. Subscriptions after the beta

When subscriptions begin, these rules apply unless your order form says otherwise:

• Plans. Plans are a flat monthly fee set by the number of licensed users (people with a sign-in) in your organization. Adding a user within your plan costs nothing; going past your plan's user limit requires moving to the next plan. Prices are those shown in the Service or on your order form when you agree to them.
• Add-ons. Some capabilities are sold as separate monthly add-ons at the price shown when you add them.
• Billing. Subscription fees are charged monthly in advance. Upgrades take effect immediately and are prorated for the rest of the billing period. Downgrades take effect at the start of the next billing period, and the current period is not refunded.
• Renewal and cancellation. Subscriptions renew each month until cancelled. A cancellation takes effect at the end of the current billing period; there is no refund for the rest of that period, except where the law requires one.
• Free trials. If we offer a free trial, its length is shown when it starts. A trial waives the subscription fee only; AI usage during a trial is charged as described in Section 3.

3. AI usage and prepaid credits

AI features use large language models. You choose how that usage is paid for:

• Neivan-managed AI. Usage is paid from a prepaid credit balance that you top up in the Service. Credits are charged at the AI provider's cost plus a markup — currently 30% — and the price is shown before you buy.
• Your own keys. If you connect your own AI provider key, your provider bills you directly for that usage, and Neivan adds no markup.

Automatic top-ups. Credits are only bought when you choose to buy them; automatic top-ups are not currently offered. Before we offer them, we will update these terms to say when a top-up is charged and what notice you receive, and you will have to turn them on yourself.

Unused credits. Prepaid credits are not refundable and have no cash value, except where the law requires otherwise or we end the Service without cause, in which case we refund any unused balance.

4. Payment

• Payments are processed by Stripe. Card details go directly to Stripe; Neivan never stores full card numbers and keeps only the card brand, last four digits, and Stripe reference identifiers.
• You authorize us, through Stripe, to charge your payment method for amounts you have agreed to: credit top-ups you buy, and — once they apply — subscription and add-on fees, prorations, and taxes.
• Invoiced amounts, where we agree to invoice, are due within 30 days of the invoice date.

5. Taxes

Prices do not include taxes. You are responsible for sales, use, value-added, and similar taxes on your purchases, other than taxes on Neivan's net income. Where the law requires us to collect a tax, we add it to the charge unless you give us a valid exemption certificate.

6. Late or failed payments

• If a charge fails or an invoice is unpaid by its due date, we notify you and may retry the charge.
• After a grace period of 5 days past the due date, the account may be restricted: users can still sign in and export their data, but cannot run agents or take actions that incur charges.
• Full access returns once the overdue amount is paid.
• If your prepaid credit balance runs out, Neivan-managed AI features may stop until you top up; features using your own keys keep working.

7. Disputes and chargebacks

If you think a charge is wrong, email [email protected] within 60 days of the charge so we can resolve it directly. If you open a chargeback instead, we may restrict the account while it is resolved and recover amounts properly owed.

8. Price changes

We may change prices, plan limits, or the credit markup. A change applies to you from your next billing period that starts at least 30 days after we email your account owners about it. Credits you already bought keep the price you paid. If you do not accept a change, you may cancel before it takes effect.
