Privacy Policy

1. Scope and contact

This policy explains how Tsung-en Hsiao (“we”) handles data for 健身輕鬆記 / Easy Workout Log on Android and Wear OS, its product website, and email support.

For privacy questions or data-rights requests, contact [email protected]. The app does not require an account.

2. App data and purposes

To provide workout recording, review, personal records, and device synchronization, the app stores and processes the following on your devices:

• Training dates, exercises, weights and units, repetitions, durations, distances, set numbers, completion times, and notes you enter.
• Custom body-part and exercise names, favorite or hidden settings, and display and interaction preferences.
• History, statistics, and personal bests calculated from your workout records.
• Record identifiers, app device identification information, versions, and synchronization status used to identify records, deliver edits and deletions, and prevent duplicates or the return of outdated data.
• Local timer and interaction-hint state, and notification permission settings.

You choose what to enter. Without a particular entry, features that rely on that entry cannot record or calculate it. Please avoid including unnecessary identity information, medical details, or other people’s personal data in notes or support emails.

The current app has no advertising, usage analytics, or crash-reporting service. It does not read Health Connect, location, contacts, camera, microphone, or body-sensor data. We do not operate a backend that receives your app workout data, and we do not receive, sell, or use your workout records for advertising through the app.

3. Phone and watch synchronization

The app on paired devices uses the Google Play services Wear Data Layer to synchronize completed records, custom exercises, supported settings, and necessary synchronization information. Timer starts, countdowns, and running state remain local to each device.

Data may travel over Bluetooth. When Bluetooth is unavailable, it may also pass through Google’s cloud infrastructure, with necessary buffering or persistence managed by Google’s service. Google’s documentation states that Data Layer transfers through Google Cloud are end-to-end encrypted. The developer not receiving workout data therefore does not mean that data never leaves your devices. We cannot specify the countries in which Google’s infrastructure processes data or independently promise a particular retention period for that service.

See the Google Wear Data Layer documentation and Google Privacy Policy. System services independently provided by Google Play, Android, and device manufacturers also operate under their applicable terms and settings.

4. Notifications and permissions

The app may request notification permission for timer-related reminders. You can deny or revoke this permission in system settings. This may affect reminders but does not prevent basic workout recording. Granting notification permission does not let the app read notifications from other apps.

5. Retention and deletion

Workout records, custom content, and preferences remain on devices with the app installed until you remove the relevant data or clear app storage. The app does not have a scheduled expiry for all workout history.

Local data uses private app storage managed by the operating system, while Google Play services protects cross-device communication. These measures cannot guarantee absolute security for any device or transmission. Please use a device lock and keep your system updated.

Deleting a set in the app removes it from normal record, statistics, and personal-record views. Its deletion status synchronizes when devices can connect. To support synchronization and prevent old records from returning, the local database may retain the original record and deletion markers. Removal from the interface is not immediate physical erasure from storage. Hiding an exercise also does not delete its history.

To remove complete local app data, clear the app’s storage through your device’s system settings or uninstall it. Your phone and watch hold separate copies: clearing one does not automatically clear the other, and another device may send its data back after reconnection. For complete removal, clear the app on every device where you use it and prevent devices that still retain data from continuing to synchronize. This does not guarantee immediate removal of transmission copies managed by system services.

The app disables Android automatic app backup. Whether a manufacturer’s transfer or backup tool keeps additional copies depends on that tool and your system settings. Please protect your devices and backups.

6. Email support

When you contact support, we receive your email address, message, and attachments you choose to send. We use them to respond, troubleshoot, and handle related requests. We and the services delivering and storing email process this information. Sending an email does not automatically give us access to workout data on your devices.

We use Resend (Plus Five Five, Inc.) to process support email. Data may be processed in the United States and locations of its service providers. See the Resend Privacy Policy and Data Processing Addendum.

We retain ordinary support correspondence for up to one year after the issue is closed, then delete it; we may delete it sooner when it is no longer needed. Where applicable law or an unresolved dispute requires retention, we keep only what is necessary for as long as needed, then delete it when that reason ends. This period applies to support-email copies we manage. Provider system records needed to deliver services or meet legal obligations are handled under the provider’s applicable terms and settings.

7. Product website and Cloudflare

The product website uses Cloudflare Pages and Cloudflare for website delivery and security. When you visit, Cloudflare processes network-request information needed to provide its services. This may include IP addresses, requested URLs and timestamps, browser or device request information, and security events. Website connection information is separate from your app workout data. Viewing this policy does not upload your app workout records.

Cloudflare may process information across its global infrastructure. Processing and retention depend on the services, settings, and applicable terms. We do not promise Taiwan-only processing or that providers keep no logs. See the Cloudflare Privacy Policy.

The website code currently includes no advertising trackers, analytics scripts, contact forms, or embedded third-party content. Before production publication, we will check whether the Cloudflare dashboard separately enables Web Analytics, additional logging, or security cookies, and align this section with the actual configuration.

8. Your data rights

Subject to applicable law, you may request access to and copies of your personal data, supplementation or correction, cessation of collection, processing or use, and deletion. Contact the email address above. We may need to reasonably verify your identity and the scope of the request.

You primarily manage app data on your own devices. We cannot remotely access or retrieve local records you have not provided to us. We will handle requests concerning support data we actually hold in accordance with applicable law. Your requests do not waive or restrict rights that cannot lawfully be waived or restricted in advance.

9. Children and non-medical use

The app is for personal workout recording and is not directed to children under thirteen. It is not a medical device and does not provide diagnosis, treatment, or medical advice. If you believe a child has provided personal data to us, please contact us so we can address it.

10. Policy changes

This policy is version 1.0. When it takes effect or is revised, this page will state its version, effective or updated date, and a summary of changes. Previously published versions will remain available for review. Before material changes to data practices take effect, we will provide appropriate notice and obtain any consent required by applicable rules. New processing that requires your consent will not begin until you consent. You may refuse or withdraw that consent; the affected feature may become unavailable, while independently functioning local workout recording remains available. This pre-publication preview is not yet effective.

11. Language and jurisdiction

This policy is provided in Traditional Chinese and English. If the versions differ or their interpretation is uncertain, the Traditional Chinese version prevails, without affecting rights that applicable law does not permit to be excluded or restricted.

To the extent that jurisdiction may lawfully be agreed, the Taiwan Taipei District Court shall be the court of first instance for disputes arising from this policy. This does not exclude mandatory jurisdiction or consumer-protection provisions of the Consumer Protection Act, Code of Civil Procedure, or other applicable law.
