Terms of Service

This supplement forms part of the Chat4U Terms between Pirsum-Mi Ltd, operating as Chat4U, and the customer accepting it. It incorporates the July 2026 Terms and replaces the September 2026 project-billing supplement for the subjects below. The existing project acceptance, authority and continued-terms provisions remain.

Project acceptance and authority

Each Chat4U project has its own subscription and acceptance record. Before activating Free access or beginning paid checkout, an authorized workspace owner or administrator must actively accept the complete linked agreement package for that project. Acceptance for one project does not accept the package for another project, even in the same workspace.

The person accepting represents that they have authority to bind the customer for the project and its workspace. Chat4U records the project, workspace, accepting user and role snapshots, document versions and hashes, time, locale, and related audit evidence. If you lack that authority, do not accept or activate the project.

Orders and billing provider

The provider identified in the project's Billing page and approval determines the payment route. For orders billed through Paddle, Paddle.com remains the online reseller and Merchant of Record under its current Buyer Terms. Paddle operates checkout, payment collection, transaction invoices, payment methods, transaction taxes and its ordinary refund and dispute processes.

For Shopify-billed projects, the customer approves Chat4U app charges in Shopify and those charges appear on the customer's Shopify bill. Shopify's applicable billing terms and payment procedures apply. This does not make Paddle a party to that order or make Shopify a replacement for Paddle on other projects. Chat4U provides and supports the service. Chat4U does not receive full card data.

Approval discloses the selected service, recurring amount and interval, trial where offered, one-time purchase amount and applicable transaction terms. Chat4U verifies the exact provider result before activating the corresponding service or purchased units. Browser navigation alone does not establish payment. Shopify one-time credits become usable only after Chat4U verifies successful invoicing for the exact approved purchase; a pending approval does not grant credits.

Taxes

Paddle's Merchant-of-Record transaction-tax responsibilities apply to Paddle orders. Shopify calculates and remits app-sale taxes where its applicable rules require it; other applicable tax obligations remain with the responsible party. The final approval and invoice show the actual charge and any assessed taxes. Neither this supplement nor a Chat4U usage balance promises that Shopify assumes every tax responsibility of Chat4U or the customer.

Trials, renewals and changes

Shopify recurring subscriptions use a 30-day cycle; annual Shopify plans and automatic credit recharge are not offered. Paddle orders retain their disclosed cadence. Trial eligibility and duration are disclosed before approval. A base-plan change does not restart the trial or reset consumed usage; reinstalling or using another project does not create another eligible trial for the same shop.

Approving capacity in a future recurring price does not grant that capacity without charge during a base-plan trial. A separately disclosed one-time purchase may provide finite capacity after successful invoicing through the original trial end. Its fixed quoted price and end date do not change because approval is delayed. It does not restart the base-plan trial, reset usage or renew automatically. Reducing a future capacity selection does not itself revoke a valid finite capacity purchase. A late invoice that cannot fund its disclosed service window is handled through the applicable financial-resolution process, without granting expired service or silently creating another purchase.

Paid increases and reductions follow the verified timing shown in Billing and provider approval. A combined change can require separate approvals. A completed first change remains effective if a later requested change is declined. For Shopify-billed orders, unchanged sold component prices are preserved unless the customer approves a separate change.

Cancellation and remaining access

An authorized owner or admin can request cancellation through project Billing. Verified unused paid access normally remains until its displayed end date. Cancellation does not itself refund an earlier charge, reset usage or grant units. A trial cancellation follows the verified trial-end behavior shown in Billing. Resubscription can require a new approval with separately disclosed charge and timing.

Removing store knowledge does not cancel billing. Disconnecting Shopify and canceling renewal disables store access immediately and separately verifies financial closure. Uninstalling invalidates store access; reinstalling does not automatically resume a canceled subscription. A pending or interrupted request is not confirmation that renewal has stopped. Shopify FROZEN billing restricts paid service without an added Paddle-style recovery period.

Refunds and support

No separate universal Chat4U refund window is introduced. Applicable law, transaction terms and the provider-specific Refund Policy govern eligibility. Use Paddle's authenticated receipt or support paths for Paddle financial matters. For a Shopify Chat4U app-charge issue, contact support@chat4u.ai with its store, project and charge reference. Use Shopify billing for its invoice and payment method details. Do not send card data or complete temporary management links.
