1. Plans and allowances
Nibvine is currently offered without a subscription fee. Each account carries a model usage allowance, metered in tokens, that covers the AI features. Your remaining balance and your usage history are visible in your profile.
- Running out of allowance disables AI features. Everything else — notes, tasks, the API, the MCP server — keeps working.
- Adding your own model provider key removes the allowance limit for the operations that use it, because the provider bills you directly.
- Free access may be rate-limited. Usage allowances are resource limits, not purchased credit or money held for you.
2. No Nibvine purchases
We do not sell paid services, subscriptions or token top-ups, and do not collect payment details for those purposes. Computed model costs and allowance balances are usage information, not invoices.
3. Payment questions
There are no Nibvine payments to refund. Contact support@nibvine.com if you have a question about an alleged Nibvine charge. Payments to a model provider are handled by that provider. This does not limit statutory rights.
4. Cancellation
You can stop using the Service and revoke connected applications at any time. There is no Nibvine subscription to cancel. Export your projects before closing your account.
5. Your own provider keys
Usage on a key you supply is billed by that provider under your agreement with them. We show the token counts we observe so you can reconcile, but we neither charge nor refund that spend.
