Terms of Service

Last updated: 2026-06-14

These Terms of Service ("Terms") govern your access to and use of the WA Auto Sender Studio browser extension, related websites, and any associated services (collectively, the "Service") operated by us ("we", "us", or "our"). By installing, copying, or otherwise using the Service, you ("User", "you") agree to be bound by these Terms.

1. Acceptance of Terms

By installing or using the Service, you confirm that you have read, understood, and agreed to these Terms and our Privacy Policy. If you do not agree, you must not install or use the Service and must uninstall any installed copies.

2. Description of the Service

WA Auto Sender Studio is a Chrome extension that automates the sending of WhatsApp Web messages on behalf of the User, using contact lists, message templates, and scheduling features provided by the User. The extension operates locally in your browser and uses our backend only for license validation and aggregated usage sync.

3. Eligibility

You must be at least 18 years old and legally capable of entering into a binding contract to use the Service. By accepting these Terms, you represent and warrant that you meet these requirements.

4. Account, License Keys, and Devices

• Paid plans are tied to a license key delivered to your email after a successful payment.
• Each license key may be activated on a limited number of devices depending on your plan (Pro: 1 device, Business: 5 devices). Activations are tracked via an anonymous device ID generated by the extension.
• You are responsible for keeping your license key confidential. We are not responsible for losses caused by unauthorized use of your license key.
• You may deactivate a device at any time via the dashboard to free up an activation slot.

5. Plans, Pricing, and Payment

Current plans and pricing are listed on our Upgrade page. Prices are denominated in the currency displayed at checkout and are exclusive of applicable taxes unless stated otherwise.

By providing a payment method, you authorize us (via Stripe) to charge the applicable fees. Subscription plans (e.g., monthly or yearly) will automatically renew at the then-current price unless cancelled before the renewal date. You may cancel auto-renewal at any time; cancellation takes effect at the end of the current billing cycle.

6. Free Tier

A free tier is provided with limited features (e.g., 20 messages per day, text-only, no CSV/group/image features). We may modify the free tier limits at any time at our sole discretion.

7. Refund Policy

Refund requests are evaluated on a case-by-case basis and must be submitted within 7 days of purchase by emailing support@wass.appza.app. If a refund is granted, the corresponding license key will be revoked and will cease to work. We reserve the right to deny refund requests where there is evidence of abuse or violation of these Terms.

8. Acceptable Use

You agree to use the Service only for lawful purposes and in a manner that respects the rights of others. You must not, and must not authorize any third party to:

• Send unsolicited bulk messages, spam, or messages to recipients who have not given you valid consent.
• Send deceptive, fraudulent, harassing, threatening, defamatory, obscene, or otherwise unlawful content.
• Impersonate any person or entity, or misrepresent your affiliation with any person or entity.
• Violate any applicable local, national, or international law or regulation, including but not limited to anti-spam, privacy, and consumer protection laws (e.g., GDPR, CAN-SPAM, PDPA).
• Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the Service, except to the extent expressly permitted by applicable law.
• Resell, sublicense, rent, lease, or otherwise commercially exploit the Service without our prior written consent.
• Use the Service to interfere with, disrupt, or attempt to gain unauthorized access to our systems or any third-party systems.
• Use any automated means (bots, scrapers, etc.) to access the Service other than as intended by the extension itself.

9. WhatsApp Terms Compliance

You acknowledge that the Service interacts with WhatsApp Web solely as a user-driven automation tool. You are solely responsible for ensuring that your use of WhatsApp Web, and any messages you send through it, comply with WhatsApp's Terms of Service and applicable laws. We are not affiliated with, endorsed by, or sponsored by WhatsApp LLC or Meta Platforms, Inc.

10. Your Content

You retain all rights, title, and interest in the contact lists, message content, and media files ("Your Content") that you upload or process through the Service. You grant us a limited, non-exclusive, royalty-free license to process Your Content solely as necessary to operate the Service on your behalf. We do not access, view, store on our servers, or use Your Content for any other purpose.

11. Data and Privacy

Our data practices are described in our Privacy Policy. By using the Service, you also agree to the Privacy Policy.

12. Intellectual Property

The Service, including all related software, designs, trademarks, and content (excluding Your Content), is and remains the exclusive property of us and our licensors. Except for the limited license granted in these Terms, no rights or licenses are granted to you, whether by implication, estoppel, or otherwise.

13. Third-Party Services

The Service relies on third-party providers, including but not limited to Stripe (payments), Supabase (backend), Firebase Hosting (web pages), and transactional email providers. We are not responsible for the availability, accuracy, or practices of any third-party service. Your use of such services may be subject to their own terms.

14. Suspension and Termination

We may suspend or terminate your access to the Service at any time, with or without notice, if we reasonably believe that you have violated these Terms, that continued provision would cause a security or legal risk, or that you have engaged in fraudulent or illegal activity. Upon termination:

• All licenses granted to you will immediately end.
• You must stop using and uninstall the extension.
• Provisions that by their nature should survive termination (including but not limited to ownership, disclaimers, indemnity, and limitations of liability) will survive.

15. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT DEFECTS WILL BE CORRECTED.

16. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL WE, OUR AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES (INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, GOODWILL, OR BUSINESS OPPORTUNITY) ARISING OUT OF OR IN CONNECTION WITH THE SERVICE, WHETHER UNDER CONTRACT, TORT, STATUTE, OR OTHER THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE 12 MONTHS PRECEDING THE CLAIM, OR (B) USD 50.

17. Indemnification

You agree to defend, indemnify, and hold us harmless from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to (a) your use of the Service, (b) Your Content, (c) your violation of these Terms, or (d) your violation of any applicable law or third-party right.

18. Changes to the Terms

We may update these Terms from time to time. The "Last updated" date at the top of this page reflects the effective date of the current version. Material changes will be communicated via the extension or by email where appropriate. Your continued use of the Service after the effective date of the revised Terms constitutes your acceptance of the changes.

19. Governing Law and Dispute Resolution

These Terms are governed by the laws of the Hong Kong Special Administrative Region, without regard to its conflict-of-laws principles. Any dispute arising out of or in connection with these Terms will be submitted to the exclusive jurisdiction of the courts of Hong Kong. Nothing in this section limits your rights under mandatory consumer protection laws of your habitual residence.

20. Miscellaneous

• Severability: If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions will continue in full force and effect.
