Effective Date: August 7, 2026
These Terms of Service ("Terms") govern your use of Sonnet (the "App"), a JSON viewer and editor for Android. By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.
Sonnet lets you open, view, edit, and save JSON files locally on your device. The App works entirely offline: it does not require an account, and the content of your JSON files is never uploaded to us or to any server. See our Privacy Policy for details on what limited data the App's third-party services (analytics, crash reporting, purchases) do collect.
The App is provided "as is." We do not guarantee that it will be uninterrupted, error-free, or compatible with every device or Android version.
The App is free to use, with a per-file size limit on the free tier. Sonnet Pro is an optional, one-time, non-subscription purchase that raises this limit. Sonnet Pro does not unlock any other feature — everything else in the App is, and will remain, free.
The Sonnet Pro purchase is processed entirely by Google Play Billing. We do not receive or store your payment details. Sonnet Pro is a one-time purchase — it does not renew, and there is no recurring charge.
Refund requests are handled by Google, under Google Play's own refund policies, not by us directly. You can request a refund through the Google Play Store. If Google grants a refund, your access to Sonnet Pro's raised file-size limit will be revoked accordingly.
You retain full ownership of any JSON files you open, create, or edit with the App. We do not access, collect, or claim any rights over the content of your files — they are processed entirely on your device.
You agree not to:
The App itself — its code, design, branding, and the "Sonnet" name and logo — is owned by the developer. These Terms grant you a limited, personal, non-exclusive, non-transferable license to install and use the App on devices you own or control, for your personal or internal use. All rights not expressly granted are reserved.
The App is provided "as is" and "as available," without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be error-free or that any errors will be corrected.
To the maximum extent permitted by applicable law, the developer will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data (including JSON files you edit with the App — we recommend keeping your own backups of important files), arising out of or related to your use of the App. Where liability cannot be excluded by law, our total liability is limited to the amount you paid for Sonnet Pro (if any) in the 12 months before the claim arose.
Nothing in these Terms limits liability for something that cannot legally be limited or excluded (for example, death or personal injury caused by negligence, or fraud) under the law of your jurisdiction.
You may stop using the App at any time by uninstalling it. We may suspend or discontinue the App, or any part of it, at any time. Sonnet Pro purchases are a one-time entitlement tied to your Google Play account; if we discontinue the App, previously purchased entitlements are not retroactively refunded solely due to discontinuation, though Google Play's standard refund policies may still apply.
We may update these Terms from time to time, for example when the App's features change. Material changes will be reflected here with an updated effective date. Continuing to use the App after an update means you accept the revised Terms.
These Terms are governed by the laws of Brazil, without regard to conflict-of-law principles. Any dispute arising from these Terms will be subject to the exclusive jurisdiction of the courts of the Comarca de São Paulo, State of São Paulo, Brazil — except where mandatory consumer-protection law in your own country of residence (for example, Brazil's own Código de Defesa do Consumidor, which for Brazilian consumers may instead entitle you to bring a claim in the courts of your own domicile) gives you additional rights or a different forum that cannot be waived by contract.
