6. Fees, Subscriptions, and Credits
6.1 Pricing and Payments Fees for use of the Service are based on the credits purchased or subscription plan selected, as described on our Pricing Page. Prices and available plans may change, but any changes will apply only to future purchases or billing cycles. All payments are final unless required by law.
6.2 Subscriptions and Automatic Renewal AUTOMATIC RENEWAL NOTICE (California residents): Subscriptions automatically renew each billing cycle until cancelled. You will be charged the then-current subscription fee to your payment method at the start of each new billing cycle unless you cancel in advance. You may cancel at any time through your account settings (Account → Billing) or by contacting support@sentisonics.com. After purchase, we will send you an acknowledgment email that includes the key terms, renewal cadence, and instructions to cancel online at any time.
(a) Monthly Credits are provided as part of each subscription plan. They refresh at the beginning of each billing cycle, expire at the end of that cycle, and do not roll over. (b) You may cancel at any time. Cancellation takes effect at the end of the current billing cycle. No refunds are issued for unused or expired Monthly Credits. (c) Upgrades: If you upgrade during a billing cycle, you will receive prorated Monthly Credits for the time remaining in your billing cycle. Your total credits for the cycle (credits already used plus credits remaining) will not exceed your new plan's monthly allowance. You will be charged based on the time remaining at the new tier price. Your full Monthly Credits under the upgraded plan begin with the next billing cycle. (d) Downgrades: If you downgrade, you retain access to your current tier and Monthly Credits until the end of the billing cycle. At the start of the next cycle, your subscription is billed at the lower rate, and you receive Monthly Credits for that tier.
6.3 Credit Types
(a) Monthly Credits – Provided only with active subscriptions. Refresh each billing cycle. Expire if not used by the end of the cycle. Do not roll over. (b) Plan Flex Credits – May be awarded during subscription upgrades or purchased à la carte. They never expire, but require an active subscription to access and use. (c) Flex Credits – Purchased separately, without subscription. They never expire and may be used at any time by any account holder. (d) Credits are non-transferable, have no cash value, and cannot be refunded or exchanged, except where required by law. (e) Deduction Priority – The Service deducts in this order: Monthly Credits → Plan Flex Credits (only if subscription is active) → Flex Credits. (f) Cancellation Effects – On subscription cancellation: remaining Monthly Credits expire at the end of the current cycle; Plan Flex Credits remain in your account but cannot be used unless you resubscribe; Flex Credits remain usable at any time.
6.4 Free Samples Each account may run up to three (3) free sample conversions that do not consume credits. Sample conversions may be limited in duration and are provided for evaluation only.
