Sales Price

Priced per person per month: Starter $4.99, Pro $19, Focus $39, and Unlimited $69 (in USD, excluding tax). Pro and higher are also available on annual billing at $190 (Pro), $390 (Focus), and $690 (Unlimited) per person per year. Starter is monthly only. Tax (VAT, GST, etc.) may be added at checkout depending on your country or region.

Consumption tax and similar taxes are calculated by the payment provider (Polar) based on the purchaser's location and are included in the total shown on the checkout screen. No charges apply other than that total (any currency conversion fees for foreign-currency payments are subject to the terms of your card issuer).

If you pay through Google Play in the Android app (one-seat monthly Pro, Focus, or Unlimited plans only), the price is shown by Google Play on the in-app purchase screen (including consumption tax in Japan). There are no charges payable to the Company other than the price shown on the in-app purchase screen.

If you pay through the App Store in the iOS app (one-seat monthly Pro, Focus, or Unlimited plans only), the price is shown by the App Store on the in-app purchase screen. There are no charges payable to the Company other than the price shown on the in-app purchase screen.

Payment Methods

• Credit card payment (payment provider: Polar)
• Google Play billing (Android app; the payment method registered with Google Play)
• App Store billing (iOS app; the payment method registered with the App Store)
• For corporate contracts, invoice payment (bank transfer) may be available under an individual agreement.

Payment Timing

• Starter (monthly only): no free trial. Charged $4.99 per person per month upon sign-up, and thereafter on each renewal date.
• Pro or higher on monthly billing (with a 7-day free trial when eligible): the first charge is made when the trial ends, and thereafter on each renewal date. If ineligible for a trial, the first charge is made upon sign-up. See the pricing page for eligibility conditions.
• Pro or higher on annual billing: charged upon application, and thereafter on each renewal date.
• Monthly plans purchased through Google Play in the Android app: if eligible, such as when purchasing the plan for the first time, a 7-day free trial applies; the first payment is charged when the trial ends, and Google Play charges on each monthly renewal date thereafter. If you cancel during the trial, you will not be charged.
• Monthly plans purchased through the App Store in the iOS app: if eligible, a free period applies (its length is shown on the in-app purchase screen); the first payment is charged when the free period ends, and the App Store charges on each monthly renewal date thereafter. If you do not want the free period to convert to a paid subscription, cancel from Subscriptions in the Settings app on your iPhone at least 24 hours before the free period ends.
• Adding members (contracts on the web): a seat is added when the person joins through the invite link, and the prorated amount for the remaining days until your next renewal is charged right away. From the next renewal, you are billed for the new seat count. (For some existing contracts, the maximum number of members during the contract term is billed on the renewal date.)
• AI usage overages (contracts on the web with Addy Unlimited mode enabled; it can newly be enabled on Focus or higher): usage beyond your plan's limit is added to the next invoice on a usage-based basis.

Service Delivery Timing

For the SaaS service (Addness), access becomes available immediately after you sign up (for free trials, from the start of the trial).

Returns and Cancellations

Due to the nature of the service, returns and refunds are generally not accepted after payment has been completed. However, this does not apply to termination for reasons attributable to the Company, cases where the Company is obligated by law to issue a refund, or erroneous or duplicate charges. In addition, if the Company terminates your contract for its own reasons or discontinues the Service, the Company will refund the unexpired portion on a pro-rata daily basis in accordance with the Terms of Service.

For purchases made through Google Play in the Android app, the same return and refund terms as above apply. Google may also issue refunds under Google Play's refund policy. For refund inquiries, please contact Google Play Help or our support contact listed above.

For purchases made through the App Store in the iOS app, the same return and refund terms as above apply. Apple may also issue refunds under the App Store's refund policy. For refund inquiries, please contact Apple Support or our support contact listed above.

Mid-Term Cancellation

For contracts on the web, the contract term is one month for monthly billing and one year for annual billing, and it renews automatically unless you cancel. For both monthly and annual plans, refunds are not available for cancellations during the contract term. You can cancel from Plan and billing in Organization settings. Canceling schedules your subscription to stop at the end of the current period; you can keep using the Service until then, and you can undo the cancellation until the end date. After cancellation, you can no longer use the Service at the end of the contract term (your data is retained, and you can continue where you left off by subscribing again). Deleting the organization cancels the subscription immediately.

For purchases made through Google Play in the Android app, please cancel from the Subscriptions screen in Google Play. If you cancel before the next renewal date, future charges stop and you can continue using the Service until the end of the current period. Deleting the app does not cancel your subscription.

For purchases made through the App Store in the iOS app, please cancel from Subscriptions in the Settings app on your iPhone. If you cancel at least 24 hours before the end of the current period, future charges stop and you can continue using the Service until the end of the current period. Deleting the app does not cancel your subscription.
