1. Acceptance of these terms
1.1 Focusti is provided and operated by Guangzhou SilentStar Technology and its owner, Zhenyu Chen ("we", "us"). Please read these terms before using the app. If you do not agree, stop using it. Matters requiring separate consent will be presented through the relevant in-app notice.
1.2 Focusti offers focus timers, focus records, reminders and related tools. Available features depend on your version of the app. You are responsible for your devices, network connection and associated costs.
2. Rules of use
2.1 Use Focusti lawfully and comply with the laws applicable in your country or region. Do not infringe intellectual property, privacy or other rights.
2.2 Do not distribute unlawful or infringing content, disrupt or attack the app or its services, bypass access restrictions or access another person's data without permission. Do not copy or resell the app or use it for unauthorized commercial activities.
3. Changes to the service
We may adjust the service for updates, maintenance or security. We will explain material changes affecting use through in-app notices or relevant pages, and obtain separate consent where required by law. Paid services are subject to the information presented at purchase and applicable subscription rules.
4. Privacy
We respect personal information. For information about collection, use, storage, sharing and your rights, read the privacy notice applicable to your version or the feature you use. These terms do not replace a privacy policy or provide additional consent.
For features involving system permissions or third-party services, review the relevant notices and manage permissions as needed. Personal information must be handled in accordance with applicable law and relevant privacy notices.
5. Devices, accounts and security
5.1 Keep your devices, app data and platform accounts secure. If a feature requires sign-in, protect the relevant credentials and contact us promptly if you identify account misuse or a security issue.
5.2 Do not share passwords or verification codes. Use appropriate device access protection and install or update the app through trusted channels.
6. Notices and reminders
Service notices may be delivered through the app, relevant webpages, system notifications or contact details you provide. Notifications and timer reminders may be affected by device state, permissions, power-saving settings or connectivity. Do not rely on them as your only reminder for emergencies or safety-critical activities.
7. Limitations and responsibilities
7.1 Focusti supports focus and time management. It does not guarantee particular study, work or health outcomes and does not replace medical or other professional advice.
7.2 We take reasonable steps to maintain the service, but cannot guarantee uninterrupted or error-free operation on every device or network. Third-party platforms, external links and system features are subject to their own rules.
7.3 You are responsible under applicable law for your unlawful, infringing or improper use. Any limitation of liability applies only to the extent permitted by law. Nothing excludes liability that cannot lawfully be excluded or limits your mandatory consumer rights.
8. Intellectual property and user content
Rights in the app software, interface, text, icons and other protected materials belong to their respective owners. Do not copy, distribute or create derivative works except as permitted by law or authorization.
Existing rights in focus records, notes and other content you enter remain with you or the relevant rights holder. Using the app does not transfer those rights under these terms.
9. Stopping use and termination
You may stop using Focusti. We may lawfully restrict or terminate services for serious breaches, security risks or discontinuation of the service, with notice where reasonably practicable. Uninstalling or stopping use does not necessarily cancel a subscription; manage it separately through the purchase platform.
10. Disputes
Please contact us using the details below to discuss questions or disputes about these terms or the service. Unresolved disputes may be referred to a legally competent authority. These terms do not limit complaint, remedy or consumer protection rights granted by applicable law.
11. Data storage and service security
Local data may be lost when uninstalling the app, changing devices, experiencing system faults or performing other operations. Back up or export important records when those features are available. Cross-device connections and widgets may require particular permissions or network conditions, as described for the feature.
Installing the app alone does not mean that all data is stored in the cloud or can be automatically recovered. Backup, synchronization and recovery depend on the features actually available in your version.
12. Minors
Minors should read these terms and use the app under a guardian's guidance. Obtain guardian consent for purchases or other matters where required by applicable law and purchase-platform rules.
13. Additional terms and subscriptions

If a provision is invalid under applicable law, the remaining provisions continue to apply to the extent permitted by law. Read any feature-specific notices together with these terms. You may contact us below with questions about the terms or the service.
