Privacy Policy & Terms of Service

Privacy Policy (English)

Steven Huang ("we", "our", or "us") operates the Daily Strong mobile application (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the App.

1. Information We Collect

1.1 Processed on your device only (not collected by us)

• Camera frames. During a workout, the device camera streams frames to Google ML Kit for pose-landmark detection. All image processing happens entirely on your device. Camera frames are processed in real-time memory and are never stored, recorded, uploaded, or transmitted to any server we operate. No images leave your device.

1.2 Information we receive about you

• Purchase data. When you start a subscription or restore a purchase, transaction data is processed by Apple (App Store) and by RevenueCat, our subscription management provider. We receive subscription status (entitlement, product identifier, purchase date, expiration, store, ownership type). We do not receive or store your payment card number or billing address.
• Anonymous device identifier. RevenueCat assigns an anonymous identifier so it can associate the App Store receipt with your device and restore purchases. This identifier is not linked to your name, email, or any account.

1.3 Information stored locally on your device

The following items are stored exclusively on your device in the App's private storage area and are never transmitted to any server we operate (we do not operate any servers):

• Workout records: exercise type, rep count, duration, quality scores, step count (for jogging), timestamps.
• Personal bests, streaks, and milestone celebration history.
• App preferences: settings, notification preferences, fitness level (Beginner / Intermediate / Advanced / Elite), workout targets, voice and sound preferences.
• Notification schedules: daily reminder time and weekdays, streak protection settings.
• Subscription status cache: a local copy of your subscription status so the App can show the correct screens while offline.

You can erase all of this data at any time through Settings → Clear All Data, or by uninstalling the App.

1.4 Information you choose to share

These data flows only happen when you tap Share (or an equivalent control):

• Photos / Camera Roll (write-only on iOS). When you tap Share on a workout summary, the App writes a single image to your iOS Photos library. We request write-only access — we do not read, scan, or upload any of your existing photos.
• System share sheet. Tapping Share opens your operating system's share sheet, letting you forward the workout summary (image and/or text) to a third-party app of your choice (e.g., Messages, Mail, LINE, WhatsApp, social networks). Once content leaves Daily Strong, it is governed entirely by the receiving app's privacy practices — please consult that app's policy.

2. How We Use Your Information

We use the information described above to:

• Provide real-time pose detection and automatic rep counting during workouts.
• Track your workout history, streaks, personal bests, and milestone celebrations.
• Schedule local push notifications (daily reminders, streak protection, idle recall) based on your preferences. These notifications are generated and delivered entirely on your device — no remote push server is involved.
• Process in-app purchases and validate subscription entitlements.
• Diagnose problems and improve the App.

3. Third-Party Services

The App integrates the following third-party services. We disclose what each one receives so you can review their respective privacy policies:

The App does not use any third-party analytics, advertising, crash-reporting, attribution, or marketing services. No data is sent to any service we operate (we do not operate any servers).

4. Data Sharing and Disclosure

We do not sell your personal information. We do not share your personal information with third parties for their own marketing purposes.

We share information only in the following limited circumstances:

• Payment and subscription processing. Purchase data is shared with Apple and RevenueCat to process transactions and validate entitlements.
• Legal requirements. When required by law, regulation, subpoena, or other legal process, or to protect rights, safety, or property.
• Business transfers. In connection with a merger, acquisition, reorganization, or sale of assets, in which case we will give notice before personal data is transferred and becomes subject to a different privacy policy.

5. Data Storage and Security

• All workout data, preferences, and settings are stored locally on your device in the App's private storage area.
• We do not operate cloud servers or remote databases. Daily Strong has no account system.
• Camera frames are processed in real-time memory only and are never written to storage.
• Communication with RevenueCat, the App Store, and Google Fonts is encrypted in transit using HTTPS / TLS 1.2 or higher.
• The App only uses encrypted (HTTPS) connections — plain-text traffic is not permitted from the App.

6. Data Retention and Deletion

• On-device data. Workout records and preferences are retained on your device until you remove them. You can erase all on-device data at any time via Settings → Clear All Data, or by uninstalling the App. Uninstalling permanently removes all workout records, personal bests, and preferences from the device.
• Subscription data held by Apple and RevenueCat. Subject to Apple's and RevenueCat's retention policies. RevenueCat retains purchase receipts for as long as needed to provide subscription services. You may request deletion of records tied to your anonymous identifier by contacting us; we will pass the request to RevenueCat on your behalf.
• Verification. Because we do not collect direct identifiers (name, email, account ID), the most reliable way to identify your records is to provide your RevenueCat App User ID (visible in Settings → Subscription if available), the original purchase Apple ID region, and an approximate purchase date.

7. Your Rights

7.1 Rights available to all users

You have the right to:

• Access your workout data inside the App's History feature.
• Delete all your local data via Settings → Clear All Data, or by uninstalling the App.
• Request a copy of any personal data we hold by emailing the address below. An in-App data export feature is planned for a future release; until then we will handle requests manually within the timelines set out below.

7.2 European Economic Area, United Kingdom, and Switzerland (GDPR)

If you are located in the EEA, UK, or Switzerland, you have the following rights under the General Data Protection Regulation:

1. Right of access (Art. 15) — request a copy of the personal data we hold about you.
2. Right to rectification (Art. 16) — correct inaccurate or incomplete personal data.
3. Right to erasure / "right to be forgotten" (Art. 17) — request deletion of your personal data. For on-device data, Settings → Clear All Data or uninstalling the App achieves this; for purchase records held by RevenueCat, contact us.
4. Right to restrict processing (Art. 18).
5. Right to data portability (Art. 20) — receive your personal data in a structured, commonly used, machine-readable format. Contact us by email to request this.
6. Right to object (Art. 21) — object to processing based on legitimate interests.
7. Right to withdraw consent (Art. 7(3)) — where processing is based on consent, withdraw at any time without affecting the lawfulness of prior processing.
8. Right to lodge a complaint (Art. 77) with your local data protection supervisory authority.

Legal basis for processing:

• Contract performance (Art. 6(1)(b)) — providing App functionality and the subscription service you have purchased.
• Legitimate interests (Art. 6(1)(f)) — improving the App, preventing fraud, and supporting Restore Purchases via the anonymous RevenueCat identifier.

Response time: We will respond to verifiable requests within 30 days, extendable by 60 additional days in complex cases as permitted by Art. 12(3).

7.3 California Residents (CCPA / CPRA)

If you are a California resident, you have the right to:

• Know what personal information is collected, used, shared, or sold (we do not sell personal information).
• Delete personal information collected from you.
• Correct inaccurate personal information.
• Opt out of the sale or sharing of personal information for cross-context behavioral advertising — we do not engage in either.
• Limit use of sensitive personal information — we do not collect sensitive personal information as defined by CPRA.
• Non-discrimination for exercising your privacy rights.

In the preceding 12 months, the categories of personal information we have processed are: (a) commercial information (subscription transactions), (b) internet or other network activity information (limited to the technical metadata of font CDN requests described in Section 3), and (c) inferences drawn from on-device fitness data that never leave your device. We have not sold or "shared" (for cross-context behavioral advertising) any personal information.

Response time: We will respond within 45 days, extendable by 45 additional days as permitted by §1798.130(a)(2).

7.4 Taiwan (Personal Data Protection Act / 個人資料保護法)

If you are in Taiwan, you have the rights guaranteed by Article 3 of the Personal Data Protection Act:

• 查詢或請求閱覽 — request access to your personal data
• 請求製給複製本 — request a copy of your personal data
• 請求補充或更正 — request correction or supplementation
• 請求停止蒐集、處理或利用 — request cessation of collection, processing, or use
• 請求刪除 — request deletion

For users under 7 years of age, processing requires the consent of a legal representative. For users aged 7–20 (limited legal capacity under Taiwan's Civil Code), a legal representative must co-sign.

8. International Data Transfers

Because RevenueCat is headquartered in the United States, and Apple and Google operate global content-delivery networks, your purchase data, anonymous device identifier, and (if applicable) Google Fonts request metadata may be transferred to and processed in jurisdictions outside the EEA, UK, Switzerland, or your country of residence.

For transfers from the EEA, UK, or Switzerland, our third-party processors rely on appropriate safeguards including:

• Standard Contractual Clauses (Module 2, Commission Implementing Decision (EU) 2021/914)
• EU–US Data Privacy Framework (where applicable to US-based processors)
• Adequacy decisions issued by the European Commission

You may request a copy of the safeguards in place by contacting us. For users in Taiwan, transfers are conducted in accordance with the Personal Data Protection Act and any applicable transfer restrictions.

9. Children's Privacy

The App is not directed to children under 13 (under 16 in the EEA / UK; under 7 in Taiwan for independent consent). We do not knowingly collect personal information from children below these ages. If we discover that a child below the applicable age has provided us with personal information without verifiable parental consent, we will promptly delete it.

The App Store age rating is set accordingly, and our marketing does not target children. If you believe a child has provided us with personal data, please contact us at the email address below.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. The "Last Updated" date at the top of this page indicates the most recent revision. Material changes will be communicated by an in-App notice or by prominently updating the "Last Updated" date. We encourage you to review this Privacy Policy periodically.

11. Contact Us

If you have any questions about this Privacy Policy, want to exercise any of your rights, or have a complaint, please contact:

• Developer / Data Controller: Steven Huang
• Email: sky904567@gmail.com
• Website: https://cos-go.com

Terms of Service (English)

These Terms of Service ("Terms") form a binding agreement between you ("you" or "User") and Steven Huang, an individual developer based in Taiwan (R.O.C.) ("we", "our", or "us"). They govern your access to and use of the Daily Strong mobile application (the "App") and any related services we provide.

By downloading, installing, accessing, or using the App, you agree to be bound by these Terms and by our Privacy Policy above. If you do not agree, do not download, install, or use the App.

1. About the App

Daily Strong is an AI-assisted home-fitness application that uses your device camera and on-device machine learning to detect exercise poses, automatically count repetitions, score movement quality, and guide circuit-training sessions. Workout data is stored locally on your device. Premium features are available through an auto-renewing subscription described in Section 5.

2. ⚠️ Important Health & Medical Disclaimer

3. Eligibility

• You must be at least 18 years old to enter into these Terms on your own behalf. In jurisdictions where the age of majority is higher (for example, age 20 in Taiwan for full legal capacity under the Civil Code), you must meet that age, or have a parent or legal guardian who agrees to these Terms on your behalf.
• The App is not directed to children under 13 (under 16 in the EEA / UK; under 7 in Taiwan for independent consent), and we do not knowingly accept users below those ages without verifiable parental consent.
• You represent that you (a) have the legal capacity to enter into these Terms; (b) are not barred from using the App under the laws of your jurisdiction; and (c) will use the App in compliance with all applicable laws.

4. License and Restrictions

Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the App on an Apple-branded device that you own or control, solely for your personal, non-commercial use.

You agree not to:

• copy, modify, adapt, translate, reverse-engineer, decompile, disassemble, or attempt to derive the source code of the App, except to the extent applicable law expressly permits;
• rent, lease, lend, sell, redistribute, sublicense, or commercially exploit the App;
• remove, obscure, or alter any proprietary notices (including copyright and trademark notices);
• use the App to violate any law, infringe any third-party right, or transmit any harmful or unlawful content;
• attempt to circumvent any subscription gating, license enforcement, or technical protection measure;
• use the App in a manner that could damage, disable, overburden, or impair our or any third-party servers or networks.

Any rights not expressly granted to you are reserved by us.

5. Subscriptions, Free Trial, Billing & Cancellation

5.1 Subscription plans

Daily Strong offers an auto-renewing premium subscription ("Pro") that unlocks the full set of exercises, circuit training, and advanced features. Subscription plan options (weekly, monthly, annual) and current prices are displayed in the App's paywall before you confirm purchase. The exact price you pay is shown in your local currency by the App Store at the time of purchase.

5.2 Free trial (where offered)

When a plan includes an introductory free trial, the duration is displayed on the paywall only if you are eligible for that trial under App Store rules. Users who have previously used an introductory offer for the same subscription group may not be eligible, and the App Store will charge the regular price immediately.

Unless you cancel at least 24 hours before the trial ends, your subscription will automatically renew at the regular price shown on the paywall, charged through your Apple ID.

5.3 Auto-renewal

• Payment is charged to your Apple ID account at confirmation of purchase.
• Your subscription automatically renews at the end of each billing period (week, month, or year) unless you cancel at least 24 hours before the end of the current period.
• Renewal charges use the same price unless we have notified you of a price change in accordance with App Store rules.
• The App Store charges your account for renewal within 24 hours prior to the end of the current period.

5.4 Managing and cancelling your subscription

You can manage or cancel your subscription at any time through your Apple ID settings (Settings → [your name] → Subscriptions on iOS). Uninstalling the App alone does not cancel your subscription.

5.5 Refunds

All purchases are final and non-refundable, except as required by applicable law or by Apple's then-current App Store refund policy. Refunds are processed exclusively by Apple. To request a refund, follow the instructions at https://support.apple.com/en-us/HT204084.

5.6 Price changes

We may change subscription prices from time to time. Where required by Apple's rules or applicable law, you will be notified in advance and given the opportunity to accept the new price or cancel before the next renewal.

5.7 Restore purchases

If you reinstall the App or change devices using the same Apple ID, you can restore your active subscription via Paywall → Restore Purchases or Settings → Restore Purchases.

6. Apple-Specific Terms (License between you and us; Apple as third-party beneficiary)

This Section 6 supplements (and prevails in case of conflict with) the rest of the Terms with respect to your use of the App on Apple devices.

1. Acknowledgement. You acknowledge that these Terms are concluded between you and us only, and not with Apple Inc. ("Apple"). We — not Apple — are solely responsible for the App and its content.
2. Scope of License. The license granted to you in Section 4 is limited to a non-transferable license to use the App on any Apple-branded products that you own or control and as permitted by the Usage Rules set forth in the Apple Media Services Terms and Conditions, except that the App may be accessed and used by other accounts associated with you via Family Sharing or volume purchasing.
3. Maintenance and Support. We are solely responsible for providing any maintenance and support services with respect to the App, as specified in these Terms or as required under applicable law. Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the App.
4. Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App to you (if any). To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty will be our sole responsibility.
5. Product Claims. We, not Apple, are responsible for addressing any claims by you or any third party relating to the App or your possession and/or use of it, including but not limited to: (a) product liability claims; (b) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (c) claims arising under consumer protection, privacy, or similar legislation.
6. Intellectual Property Rights. In the event of any third-party claim that the App or your possession and use of the App infringes that third party's intellectual property rights, we, not Apple, will be solely responsible for the investigation, defense, settlement and discharge of any such intellectual property infringement claim.
7. Legal Compliance. You represent and warrant that (a) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country; and (b) you are not listed on any U.S. Government list of prohibited or restricted parties.
8. Developer Contact Information. For questions, complaints, or claims about the App, contact us at sky904567@gmail.com.
9. Third-Party Terms of Agreement. You must comply with applicable third-party terms of agreement when using the App.
10. Third-Party Beneficiary. You and we acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and that, upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof.

7. User Conduct

You agree to use the App only for lawful purposes and in accordance with these Terms. You may not:

• use the App in any way that could harm the App, our reputation, or other users;
• impersonate any person or entity, or misrepresent your affiliation with a person or entity;
• use any robot, spider, scraper, or other automated means to access the App without our prior written permission;
• attempt to gain unauthorized access to any portion of the App or its related systems;
• use the App to develop a competing product or service.

We reserve the right to suspend or terminate your access to the App at any time for any breach of these Terms.

8. User Content & Sharing

When you tap Share on a workout summary, the App generates an image (and optional text) and hands it to your operating system's share sheet for distribution through an app you choose (e.g., Messages, Mail, social networks). You retain all ownership rights in the content you create; we claim no ownership over your workout summaries.

Once content leaves Daily Strong via the share sheet, it is governed entirely by the receiving app's terms and privacy policy. You are solely responsible for the content you choose to share, including compliance with the receiving platform's rules and applicable law.

9. Intellectual Property

The App, including all software, designs, text, graphics, audio, images, animations, trademarks, logos, and the selection and arrangement thereof, is owned by Steven Huang or its licensors and is protected by copyright, trademark, and other intellectual property laws.

"Daily Strong" and any associated logos are trademarks of Steven Huang. You may not use these marks without our prior written permission.

Third-party libraries used in the App are licensed under their respective open-source licenses, which take precedence to the extent of any conflict with these Terms.

10. Privacy

Our handling of personal information and on-device data is described in the Privacy Policy above, which is incorporated into these Terms by reference. By using the App you acknowledge that you have read and understood the Privacy Policy.

11. Disclaimers (AS-IS)

To the maximum extent permitted by applicable law:

• The App is provided "AS IS" and "AS AVAILABLE", without warranty of any kind, whether express, implied, statutory, or otherwise, including without limitation warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement, and quiet enjoyment.
• We do not warrant that the App will be uninterrupted, error-free, secure, free of viruses or other harmful components, or that defects will be corrected.
• We do not warrant the accuracy of pose detection, rep counting, quality scoring, or step counting. These outputs depend on environmental conditions (lighting, camera angle, framing, clothing) and on the underlying machine learning model, and may produce false positives, false negatives, or inaccurate scores.
• We make no warranty regarding any third-party services (including Apple, Google ML Kit, RevenueCat, or Google Fonts), or that your use of such services will achieve any particular result.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you.

12. Limitation of Liability

To the maximum extent permitted by applicable law:

• In no event will we, our affiliates, or our suppliers be liable to you for any indirect, incidental, special, consequential, exemplary, or punitive damages, including without limitation damages for personal injury, lost profits, lost data, business interruption, or loss of goodwill, arising out of or in connection with your use of, or inability to use, the App, whether based in contract, tort, negligence, strict liability, or otherwise, even if we have been advised of the possibility of such damages.
• Our total cumulative liability to you for all claims arising out of or relating to the App, regardless of the form of action, will not exceed the greater of (a) the amounts you actually paid to us through Apple in the twelve (12) months preceding the event giving rise to liability, or (b) NT$1,000.
• Nothing in these Terms limits or excludes liability that cannot lawfully be limited or excluded under applicable law (for example, liability for death or personal injury caused by negligence, or fraud).

13. Indemnification

You agree to indemnify, defend, and hold harmless Steven Huang from and against any claims, liabilities, damages, losses, and expenses, including reasonable attorneys' fees and costs, arising out of or in any way connected with (a) your access to or use of the App; (b) your violation of these Terms; (c) your violation of any third-party right, including intellectual property or privacy rights; or (d) any content you share via the App.

14. Termination

• These Terms remain in effect for as long as you use the App.
• You may terminate these Terms at any time by uninstalling the App and cancelling any active subscription through your Apple ID settings.
• We may suspend or terminate your access to the App at any time, without notice, if we reasonably believe you have breached these Terms or for any other reason in our sole discretion.
• Sections that by their nature should survive termination — including Sections 2 (Medical Disclaimer), 9 (IP), 11 (Disclaimers), 12 (Limitation of Liability), 13 (Indemnification), 15 (Governing Law), 16 (Changes), 17 (Miscellaneous), and 18 (Contact) — will survive termination.

15. Governing Law & Dispute Resolution

• These Terms are governed by the laws of Taiwan (R.O.C.), without regard to its conflict-of-laws principles.
• The parties shall first attempt in good faith to resolve any dispute arising out of or relating to these Terms through informal negotiation by emailing sky904567@gmail.com.
• If a dispute cannot be resolved through negotiation within thirty (30) days, the parties agree that the Taiwan Taipei District Court shall have exclusive jurisdiction as the court of first instance, except where mandatory law requires otherwise.
• If you are a consumer residing in the European Union, the United Kingdom, or another jurisdiction whose consumer-protection law grants you the right to bring proceedings in your country of residence, nothing in this Section overrides that right.

16. Changes to These Terms

We may update these Terms from time to time. When we do, we will revise the "Last Updated" date at the top of this page. If the changes are material, we will provide reasonable advance notice through an in-App notice or other prominent means before they take effect.

Your continued use of the App after changes take effect constitutes acceptance of the revised Terms. If you do not agree to the revised Terms, you must stop using the App and may cancel any subscription through your Apple ID settings.

17. Miscellaneous

• Entire Agreement. These Terms, together with the Privacy Policy, constitute the entire agreement between you and us regarding the App and supersede all prior or contemporaneous understandings.
• Severability. If any provision of these Terms is held invalid or unenforceable, that provision will be enforced to the maximum extent permitted, and the remaining provisions will remain in full force and effect.
• No Waiver. Our failure to enforce any right or provision will not be deemed a waiver of that right or provision.
• Assignment. You may not assign or transfer these Terms, by operation of law or otherwise, without our prior written consent. We may freely assign these Terms.
• No Agency. No agency, partnership, joint venture, or employment is created as a result of these Terms.
• Headings. Section headings are for convenience only and have no legal effect.
• Language. These Terms are provided in English and Traditional Chinese (繁體中文). In the event of any inconsistency, the English version controls, except where mandatory law in your jurisdiction requires otherwise.
