Jax Sets Terms of Use

Version: 1.0　Effective date: 2026-10-24

1. The app and these terms

Jax Sets is provided by Jax, an individual operator. Contact: jaxops@163.com. The app provides interval training plans, timers and training records. Personal information practices are described in Jax Sets Privacy Policy in the same release. The legal center is at `https://legal.jax-cn.top`.

These terms also cover your use of a Jax Account in Jax Sets. Accepting them does not automatically constitute consent to new purposes or data sharing in other Jax products.

2. Sign-in and account security

We currently verify identity using Sign in with Apple. Jax does not ask you to give us your Apple Account password or verification codes. Use an Apple Account you are entitled to use and protect your device and credentials. If you notice suspicious activity, you can sign out relevant devices and contact us. Your public user number identifies an account; it is not a password and does not authorize access to account data.

If sign-in is interrupted, follow the instructions to resume or verify your identity again. We may require verification to prevent unauthorized actions. This does not give us access to all content in your Apple Account.

At initial release in mainland China, cloud accounts are unavailable to children under 14. Users aged 14–17 require guardian consent. See the product privacy policy for local features and conditions in other regions.

3. Products and data scope

One Jax Account may be used in participating products, but product data is managed within its product scope. We do not automatically use one product's data in another merely because they share an account, except where we have clearly explained the processing and have an appropriate basis for it. Before using cloud features, review that product's sync and privacy information. Any transfer of local data into an account follows the product's selection process.

4. Local features and cloud sync

You can use available local features without signing in. Cloud sync requires sign-in and the applicable agreement and data ownership steps shown in the app. Sync currently covers training plans, completed training records, and nickname and gender preferences. It does not upload an entire account backup of an active workout, daily timer state or all device settings.

Age eligibility and guardian requirements for cloud accounts are described in the children and young people section of the Jax Sets Privacy Policy. Local timers that do not require an account remain available when cloud eligibility is not met.

Sync helps keep data consistent across devices. It is not an independent backup and does not guarantee recovery of every historical version. Lost connectivity, conflicts or account changes may delay updates. Check sync status and review conflict notices. Different accounts have separate data; switching accounts does not automatically merge them.

5. Training and timers

The app assists everyday training and timing. It does not provide medical diagnosis, treatment or individualized medical advice. Exercise according to your circumstances. Stop if you feel unwell and seek professional help when appropriate. Device shutdown, system restrictions, permissions, volume and other operating conditions may affect alerts and background behavior. Check required permissions and sound settings before training. Do not rely on the app as your only safety measure or emergency alert tool.

6. Local files and content

You may use the import, export and data management features available in your version. Review file sources and overwrite warnings. Exported files may contain plans, training records and profile information, and should not be assumed to be encrypted. Protect them and manage copies you export or share. Device failure, system operations, deletion or uninstallation may affect local data. Uninstalling is not guaranteed to clear all system secure storage or content saved elsewhere.

You must have the right to use content you enter, import or share. We process it only as necessary for the described features. Using the service does not give us a blanket license to use training content for advertising or unrelated purposes. Rights in the app's code, design and assets belong to their respective owners. Open-source components remain subject to their licenses.

7. Acceptable use and service operation

Do not impersonate others, steal credentials, bypass access controls or disrupt the service. We may restrict affected features to address substantiated security risks or unlawful misuse, and explain the reason and provide a contact channel where appropriate. Connectivity, devices, Apple services, maintenance and faults can affect online availability. We take maintenance and security measures appropriate to the service and its risks, but do not promise uninterrupted service or that data loss can never occur.

8. Service changes and account management

Features, pricing arrangements and recovery capabilities not offered in the current version are not promises. If paid services are introduced, prices, benefits and transaction terms will be explained before purchase. These terms do not automatically authorize charges or subscriptions.

Use account screens to manage devices and the scope of deletion. If you do not accept an important update, affected online features may be unavailable, while local training and access remain available as explained in the product. We will not delete unsynced content or block necessary deletion requests solely because you have not confirmed revised terms.

Signing out ends the relevant sign-in state; it does not delete your cloud account or data. Stopping Sign in with Apple in Apple settings invalidates the relevant authorization and sign-in state. It does not itself submit a Jax data deletion request.

Jax Sets account management provides deletion for this product and its associated relationship and data; it does not delete other Jax products. For deletion or other rights requests concerning the entire Jax Account, contact the email address above so we can verify identity and the affected scope. Processing may involve cloud cleanup and revoking external authorization. Check the progress screen or contact support to confirm completion. Any legally required or necessary security retention is described in the privacy policy and is not used to continue ordinary services you have deleted. Exported files, copies on other offline devices and copies held by third parties must be managed separately.

9. Updates, responsibility and contact

We provide summaries and any required confirmation according to the nature of changes, and make accepted versions available. We take reasonable maintenance and security measures. These terms do not exclude liability that cannot legally be excluded or restrict your statutory consumer or privacy rights. Send questions, feedback and rights requests to the contact address above.

We retain applicable versions. Updated versions and effective dates are available through About and the sign-in agreement links. Where confirmation is required by law or the nature of a change, silence or a preselected option will not replace it. You may choose not to enable online features governed by new terms and manage existing data as described in the product. Necessary deletion and privacy rights channels will not be blocked solely because you have not accepted new terms.

These terms do not exclude your statutory consumer or privacy rights or relieve the provider of legal responsibilities. Contact the address above with account or terms questions. Disputes are handled under applicable law by competent bodies; these terms do not exclude remedies available to you by law.
