Terms of Service

Effective date: July 5, 2026
These Terms of Service ("Terms") govern your use of the One Nudge application for Shopify ("the app," "the service"). By installing or using the app you agree to these Terms on behalf of the store you operate. If you do not agree, do not install or use the app.

1. What the service does

One Nudge monitors checkouts that customers start but do not complete on your Shopify store and sends at most one SMS reminder per abandoned checkout, containing a link back to the customer's cart, at a delay you configure. Messages are sent through your own Twilio or Sinch account using credentials you connect inside the app. One Nudge is not a bulk-messaging or marketing-broadcast tool and provides no way to send repeat or follow-up messages to the same cart. The app enforces consent at send time: it will only message customers whose checkout carries an affirmative SMS-marketing opt-in.
2. Your SMS provider account
  • You must maintain your own account with Twilio or Sinch. All per-message carrier fees, phone-number fees, and any registration fees (such as A2P 10DLC in the United States) are billed to you directly by your provider and are separate from the app's subscription price.
  • You are responsible for keeping your provider account in good standing and your credentials current in the app. If your provider rejects a message (for example, for insufficient funds or an unregistered number), the app records the failure and does not retry.
  • You can disconnect your provider at any time on the Nudge page, which removes your stored credentials.

3. Messaging laws and consent — your responsibility

You are solely responsible for ensuring that your use of the app complies with the messaging and privacy laws that apply to you and your customers — including, where applicable, the U.S. Telephone Consumer Protection Act (TCPA), CTIA messaging guidelines, Canada's CASL, the EU/UK GDPR and ePrivacy rules, and your carrier and provider policies. The app helps by refusing to send to any customer without an affirmative SMS opt-in from checkout, but you remain responsible for the rest of lawful messaging: enabling the SMS-marketing consent option in your Shopify checkout settings so consent can be collected, the content of your messages, and any registration your provider requires. Customers can opt out at any time by replying STOP, and opt-outs are enforced by your SMS provider; you must not attempt to circumvent an opt-out.

4. Price and billing

  • The service costs a flat $9.00 USD per month, charged through Shopify's billing system on your Shopify invoice. There is no free trial and no usage-based charges from One Nudge.
  • An active subscription is required to turn the app on and for reminders to send. The app verifies your subscription before every send.
  • You can cancel at any time by uninstalling the app or by using Delete Account on the app's Account page; either cancels the subscription through Shopify. Refunds, proration, and billing disputes are handled under Shopify's billing terms.

5. Your data

How the app collects, uses, retains, and deletes data — including automatic deletion of captured checkouts after 30 days, activity records after 12 months, and full deletion on uninstall or account deletion — is described in the Privacy Policy, which is part of these Terms.

6. Acceptable use

You agree not to use the app to:
  • send unlawful, deceptive, harassing, or abusive messages, or content that violates your SMS provider's acceptable-use policies;
  • message people without a lawful basis to do so, or after they have opted out;
  • probe, disrupt, or attempt to access data belonging to another store; or
  • resell or white-label the service without written permission.
We may suspend or terminate access for violations of these Terms or where required to protect the service, other merchants, or message recipients.

7. Service availability and changes

We work to keep the service reliable, but it is provided "as is" and "as available." Reminder delivery also depends on systems outside our control — Shopify's webhooks, your SMS provider, and carrier networks — so we cannot guarantee that any particular message will be delivered or that delivery will occur at an exact time. We may improve or modify features; if we make material changes to these Terms, we will update this page and its effective date, and continued use after a change constitutes acceptance.

8. Disclaimer and limitation of liability

To the maximum extent permitted by law: the app is provided without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement; we are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits or revenues; and our total aggregate liability for any claim relating to the service is limited to the amount you paid One Nudge in the three (3) months before the event giving rise to the claim. Nothing in these Terms limits liability that cannot be limited by law.

9. Indemnity

You agree to indemnify and hold us harmless from claims, penalties, and costs (including reasonable attorneys' fees) arising from your violation of messaging or privacy laws, your message content, or your breach of these Terms.

10. Termination

These Terms apply while the app is installed. Uninstalling the app or deleting your account ends the subscription and triggers deletion of your stored data as described in the Privacy Policy. Sections 3, 8, and 9 survive termination.
