Effective Date: June 1, 2026
Supplement to the ToS - Version dated June 1, 2026
These Billing Terms supplement the ToS and govern plans, usage measurement, invoicing, payments, failed payments, overages, refunds, chargebacks and price changes. Capitalized terms not defined here have the meaning given in the ToS.
1.1 Plans run for the billing period selected in the ordering process or order form, such as monthly or annually, and automatically renew for successive periods unless terminated in due time.
1.2 Cancellations take effect at the end of the current billing period unless the order form or mandatory law provides otherwise. No pro rata refund is provided for unused periods unless expressly agreed or required by mandatory law.
1.3 Customer is responsible for cancelling through the dashboard, account area, support process or other method specified by Provider. Deleting an app, API key or integration does not automatically cancel a paid plan unless the cancellation process is completed.
2.1 Usage Limits and billing metrics are defined in the order form, pricing page, plan description or dashboard. Unless a plan description or order form expressly provides otherwise, usage is calculated based on subscribers count, customers count, one-off payments count.
2.2 Provider uses system-based measurement methods for the metrics defined in Section 2.1. Customer has no right to inspect internal security, anti-fraud or measurement algorithms, but may request a comprehensible billing statement showing the basis of the relevant charges.
2.3 Customer must ensure that identifiers, events and configuration data used for billing are accurate and not artificially manipulated, duplicated, rotated or suppressed to avoid fees.
2.4 The dashboard displays usage information to allow Customer to monitor usage, plan status, thresholds, caps and billing-relevant metrics. Such display is provided for transparency and control and may be delayed. Provider's backend billing records are authoritative unless Customer demonstrates a material error.
3.1 The plan description may provide for warning thresholds, soft limits, hard limits, automatic upgrades, overage fees or feature restrictions if Usage Limits are reached or exceeded. Automatic upgrades are plan-dependent and apply where expressly provided in the applicable plan description, order form or dashboard configuration.
3.2 Overage fees apply only to the Scale plan, unless expressly agreed otherwise in an order form or plan description. The Scale plan includes up to 3,000 subscribers. If Customer exceeds 3,000 subscribers, overages are charged for each additional block of up to 1,000 subscribers, based on the subscriber metric calculated under Section 2.1 and the then-applicable Scale plan pricing.
3.3 Before charging overages for the Scale plan, Provider will send a warning by e-mail to the billing contact, account owner or other contact address configured in the account, where technically and operationally practicable. Failure to receive or read such warning does not prevent overages from applying if the relevant Usage Limit is exceeded and the plan provides for overages.
3.4 Hard caps or hard-limit controls are configured for the applicable plans as shown in the plan description, order form or dashboard. Where a hard cap applies, Provider may limit further usage, restrict features, block additional subscribers or events, or require an upgrade before additional usage is permitted. Customer remains responsible for monitoring usage in the dashboard and for operating within applicable hard caps.
3.5 Upgrades may take effect immediately if available for the applicable plan. Billing may be prorated or charged in accordance with the ordering process or plan description. Downgrades generally take effect at the end of the current billing period unless otherwise specified. Downgrades may result in loss of features, reduced limits, restricted access or shortened retention periods.
3.6 If Customer disputes usage or charges, Customer must notify Provider without undue delay, and in any event within 14 days after the relevant invoice or usage record becomes available, and provide reasonable supporting information. Undisputed amounts remain due and payable. Provider will review the dispute in good faith on the basis of backend billing records, dashboard data, relevant logs and Customer's supporting information. If Provider confirms a material billing error, Provider will correct the invoice or issue an appropriate credit. If no material error is identified, the original charges remain payable.
4.1 Customer authorizes Provider and/or Provider's payment service provider to charge the payment method on file for all due fees, overages, taxes and other charges.
4.2 Customer must keep payment and billing information current and ensure that charges can be collected.
4.3 If a payment fails, Provider may retry collection, request updated payment details, restrict features, switch the account to read-only mode, suspend the Service, or terminate for cause after reasonable notice.
4.4 Provider may recover outstanding amounts, statutory default interest, reminder fees and reasonable collection costs to the extent permitted by law.
5.1 Prices include statutory VAT where applicable unless stated otherwise. Customer must provide accurate tax information, including VAT ID, billing address and tax status.
5.2 If withholding tax, reverse charge or similar tax mechanisms apply, Customer remains responsible for compliance unless mandatory law provides otherwise. Amounts payable to Provider must not be reduced except where required by mandatory law.
5.3 Invoices are provided electronically, for example in the dashboard or by e-mail. Customer must review invoices and notify Provider of invoice disputes without undue delay.
6.1 Fees are generally non-refundable. Refunds are granted only where required by mandatory law or expressly agreed by Provider.
6.2 Service credits, goodwill credits or SLA credits, if any, are granted solely in accordance with the applicable SLA or Provider's express decision and are not redeemable for cash unless mandatory law requires otherwise.
6.3 Customer agrees to contact support before initiating a chargeback or payment dispute. In the event of chargebacks or payment disputes, Provider may suspend the account, recover chargeback fees and require an alternative payment method to the extent permitted by law.
6.4 Provider is not responsible for refunds, chargebacks, disputes, payout delays, taxes or fees relating to payments between Customer, End Users and Third-Party Services such as Stripe.
7.1 Provider may change prices, introduce new fees or modify plan structures for future billing periods.
7.2 Material price changes for existing paid subscriptions will be announced at least 30 days before they take effect unless shorter notice is required by law or Third-Party Service changes.
7.3 Customer may terminate the affected subscription before the effective date of a material price change. Continued use after the effective date constitutes acceptance of the changed pricing to the extent permitted by law.
