Terms of Service

Last updated: May 21, 2026

These Terms of Service (“Terms”) govern your use of the Kairos: Pomodoro Timer mobile app (the “App”) provided by Emmanuel Chargoy (“we”, “us”). By downloading, installing, or using the App you agree to these Terms. If you do not agree, do not use the App.

1. The Service

Kairos is a Pomodoro-style focus timer. Features include customizable timer presets, session statistics, gamification (XP, levels, streaks, achievements), theme customization, optional account sign-in, optional cloud sync of your data, and localized interfaces in English and Spanish. Some features are free; others are available only with an active premium subscription.

2. Eligibility

You must be at least 13 years old to use the App. By using the App you represent that you meet this requirement.

3. Your account

You can use the core App without an account. If you create one, you are responsible for maintaining the confidentiality of your credentials and for activity that occurs under your account. Tell us promptly if you believe your account has been compromised. We may suspend or terminate accounts that violate these Terms or that are used to abuse the Service.

4. Subscriptions and purchases

The App may offer optional paid subscriptions that unlock premium features such as extended statistics, cloud sync, and custom presets. At the time these Terms were last updated, the planned tiers are:

  • Monthly — USD $4.99 per month
  • Yearly — USD $29.99 per year
  • Lifetime — USD $79.99 one-time

Specific pricing, billing cadence, included features, and offered tiers may change. The actual price and terms in effect when you purchase will be shown to you in the App’s purchase screen and at checkout in the App Store or Google Play, and those displayed terms govern the transaction.

All purchases are processed by Apple (App Store) or Google (Google Play). Recurring subscriptions automatically renew at the end of each billing period until you cancel them in your App Store or Google Play account settings. Cancellations take effect at the end of the current period. Refunds and billing disputes are handled under Apple’s or Google’s standard policies; we cannot process refunds directly.

5. Acceptable use

You agree not to:

  • Reverse-engineer, decompile, or attempt to extract source code from the App, except where applicable law expressly permits it.
  • Interfere with, disrupt, or attempt to gain unauthorized access to the App or its supporting infrastructure.
  • Use the App to violate any law or the rights of others.
  • Resell, sublicense, or commercially redistribute the App or access to it.

6. Intellectual property

The App, including its code, design, trademarks, and content, is owned by us or our licensors and is protected by intellectual property laws. We grant you a personal, non-exclusive, non-transferable, revocable license to use the App for its intended purpose subject to these Terms. The content you create inside the App (such as your timer presets and session history) remains yours.

7. Privacy

Our Privacy Policy describes how we handle data in connection with the App and is incorporated into these Terms by reference.

8. Third-party services and stores

The App is distributed through the Apple App Store and Google Play and integrates third-party services (including Firebase, Mixpanel, and Sentry). Your use of those stores and services is also subject to their own terms. We are not responsible for outages or actions of those third parties.

9. Disclaimer of warranties

The App is provided “as is” and “as available” without warranties of any kind, whether express or implied, including without limitation the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or that any data will always be available or recoverable.

10. Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or use, arising out of or in connection with the App. Our total aggregate liability for any claim relating to the App will not exceed the greater of (a) the amount you paid us for the App in the twelve months before the event giving rise to the claim, or (b) USD $50.

11. Termination

You may stop using the App at any time by uninstalling it. We may suspend or terminate your access to the App or your account if you breach these Terms or use the App in a way that creates risk for us or other users. Sections that by their nature should survive termination (such as intellectual property, disclaimers, and limitation of liability) will survive.

12. Governing law

These Terms are governed by the laws of Mexico, without regard to its conflict-of-laws principles. To the extent permitted by local consumer-protection law, any dispute will be brought in the courts of Mexico City, Mexico.

13. Changes to these Terms

We may update these Terms from time to time. When we do, we will update the “Last updated” date above and, where appropriate, notify you in the App. Continued use of the App after changes take effect means you accept the revised Terms.
