These Terms of Service govern your access to and use of ReadTone's website, browser extension, and related services (collectively, the Service). By accessing or using the Service, you agree to these Terms.

Terms of Service

Effective Date: January 15, 2026 | Last Updated: March 17, 2026

1. About ReadTone

ReadTone is an AI-powered Text-to-Speech (TTS) web application. By accessing or using the Service, you agree to these Terms of Service ("Terms"). If you do not agree, do not use the Service.

Contact: [email protected]

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries related to billing and handles returns.

ReadTone (not Google) is the seller and provider of the Service. Google is not responsible for the Service, its content, or any claims related to your use of the Service. Any questions, complaints, or claims regarding the Service should be directed to ReadTone at [email protected].

2. Eligibility

You must be at least 18 years old (or the age of majority in your jurisdiction) to use the Service. By using the Service, you confirm that you meet this requirement.

3. The Service

ReadTone provides AI-powered text-to-speech conversion, turning written text into natural-sounding audio. The Service is available as:

A web app at readtone.com
A browser extension for Chrome and Edge, available on the Chrome Web Store

Features may be added, modified, or discontinued at any time.

4. Accounts & Security

For paid plans with a free trial, a payment method is required at signup. If you do not cancel before the trial ends, your subscription starts automatically and your payment method will be charged. Your subscription renews monthly until cancelled.

By starting a trial or subscription, you authorize ReadTone and/or Paddle to charge your payment method at the end of the trial and each month thereafter until you cancel.

6. EU-Based Processing

By default, API requests are processed by servers located around the world. To enable EU-only data processing, use eu-api.readtone.com instead of api.readtone.com as your API endpoint. This ensures your data is processed exclusively within the EU. EU-based processing incurs a 20% surcharge on your subscription plan.

7. Cancellation

You can cancel your subscription at any time through your subscription settings. Cancellation stops future renewals immediately. You will retain access to your plan until the end of your current billing period. The cancellation process is straightforward and will not be obstructed.

8. Monthly Character Allowance

Your monthly character allowance resets on your billing date each month
Unused characters do not carry over to the next month
Cancelling your subscription does not entitle you to a refund for unused allowance
Bonus characters (available on paid plans) are provided daily when your monthly allowance is exhausted

9. Refund Policy

All subscription payments are final. We do not provide refunds. This includes:

Charges that occur after free trial conversion
Monthly subscription charges
Partial billing periods
Unused monthly or daily character allowances

If you believe you were charged in error (for example, a duplicate charge), contact us at [email protected]. Include your account email, charge date, amount, and any invoice reference. We will review and respond promptly.

Refunds, if approved, are processed exclusively through Paddle as our Merchant of Record — not directly by ReadTone. Please see our full Refund Policy page for details.

EU/UK users: You may have a statutory 14-day right of withdrawal for distance contracts. However, because ReadTone provides immediate digital access upon subscription, this right may be waived with your express consent at checkout where legally required.

10. Service Features & Limitations

a. Text Highlighting

Word-level text highlighting (syncing on-screen text with audio) is available on all plans including Free. Current limitation: highlighting is available in English only (en-US and en-GB). Support for additional languages is in development.

b. Speed Reading

Adjustable playback speed is available on paid plans (Basic and Plus) only. It is not included in the Free Plan.

c. Browser Extension

The ReadTone browser extension allows you to read selected text on any web page. By default, the extension reads selected text only. Full-page reading requires explicit user activation. The extension is subject to the same Terms, plans, and character limits as the web app.

11. Acceptable Use

You agree not to:

Use the Service for unlawful, fraudulent, or harmful activity
Attempt to bypass usage limits, security measures, or access controls
Reverse engineer, resell, or redistribute the Service without authorization
Infringe intellectual property rights or violate any applicable laws
Interfere with or disrupt the Service or its infrastructure

We reserve the right to suspend or terminate access for violations of these Terms.

12. Data Handling

ReadTone does not store your text input history or generated audio files. Text is processed transiently to produce audio output during use. When using the browser extension, selected text or page content is accessed only when you initiate a text-to-speech action and is transmitted securely (via HTTPS) for processing. For full details, see our Privacy Policy.

13. Intellectual Property

The Service (excluding content you provide) is owned by ReadTone or its licensors and is protected by applicable intellectual property laws. We grant you a limited, non-exclusive, non-transferable license to use the Service in accordance with these Terms.

14. Third-Party Services

We use third-party providers including Paddle (payments) and Google Analytics (usage analytics). Use of the Service may also be subject to their respective terms and privacy policies.

15. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not guarantee uninterrupted operation or perfect text-to-speech output accuracy.

16. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, READTONE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, OR BUSINESS OPPORTUNITY. OUR TOTAL LIABILITY FOR ANY CLAIM WILL NOT EXCEED THE AMOUNT YOU PAID TO READTONE IN THE 30 DAYS PRIOR TO THE EVENT GIVING RISE TO THE CLAIM.

17. Indemnification

You agree to defend, indemnify, and hold harmless ReadTone from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising from your use of the Service, your content, or your violation of these Terms.

18. Account Deletion

You may close your account and request data deletion at any time via the "Delete Account" option in your dashboard settings. Your ReadTone account data is deleted immediately upon request. Some records may be retained by Paddle where required for billing, tax, or legal compliance. Uninstalling the browser extension removes all locally stored extension data from your device.

19. Changes to These Terms

We may update these Terms from time to time. Material changes will be communicated through the Service or by email. Continued use of the Service after the effective date of any update constitutes your acceptance of the revised Terms.
