1. Introduction & Scope

YUEJIETRADE Technology Studio operates the website yuejietrade.com and publishes a portfolio of mobile applications distributed through the Apple App Store, Google Play Store, and other distribution platforms. This Privacy Policy applies to your use of:

  • Our website at yuejietrade.com and all subdomains;
  • Our mobile applications (collectively, "YUEJIETRADE Apps"), including but not limited to: Offline Audio Editor, Pantry Freshness, Trip Logger, License Vault, Goal Engine, and Collection Vault;
  • Email, web, and other communications you send to or receive from us;
  • Any other services we offer that display or link to this Policy.

Core principle: YUEJIETRADE is built on a local-first architecture. Most of your content never touches our servers. Where we do collect it, this Policy explains exactly what is collected, why, and how to exercise your rights.

TL;DRWe collect the minimum information necessary to operate, secure, and support our products. We do not sell personal data. We do not perform cross-app tracking.

2. Information We Collect

We collect information in three categories: information you give us directly, information collected automatically through your use of our products, and information from third parties.

2.1 Information You Provide Directly

  • Account information. If you create an account (e.g., opt-in cloud sync or newsletter subscription), we collect your name, email, and password. You may also sign in via Apple, Google, or other federated providers — we receive only the information authorized by you.
  • Support communications. When you contact support@yuejietrade.com or contact@yuejietrade.com, we collect the content of your message, metadata, and any files or screenshots you send.
  • User content. In apps that support user-generated content, the content is stored locally on-device by default. You may opt to sync to our cloud; in that case we store the encrypted content necessary to provide sync.
  • Feedback & survey responses. If you respond to optional surveys, we collect your responses.

2.2 Information Collected Automatically

  • Device information. Device model, OS version, locale, time zone, and a randomly generated installation identifier.
  • Usage information. Aggregated, privacy-preserving counts of feature usage, crash logs, and performance telemetry. Where possible this is computed locally on-device using differential privacy.
  • Log information. IP address (truncated, retained 7 days), request timestamps, referrer.
  • Advertising identifiers. In apps that show advertising, the device's advertising identifier (IDFA/GAID) is accessed only after explicit consent via App Tracking Transparency or equivalent Android controls.

2.3 Information From Third Parties

If you sign in through a third-party identity provider, we receive only the profile fields you explicitly authorize. We do not receive your contacts, photos, or other private data from those providers.

3. How We Use Information

We use the information we collect for the following purposes:

  • To provide, maintain, secure, and improve our apps and website.
  • To authenticate users and provide opt-in cloud sync features.
  • To respond to your support communications.
  • To send administrative information (terms changes, security notices).
  • To send marketing communications, only where you have given explicit consent or where permitted by law.
  • To serve contextual advertising through our advertising partners, only after consent.
  • To detect, prevent, and address fraud, security incidents, and abuse.
  • To comply with our legal obligations and enforce our terms.

We do not use your information for automated decision-making that produces legal or similarly significant effects.

4. Legal Bases for Processing (GDPR)

Where the EU General Data Protection Regulation (GDPR) applies, we process personal data on the following legal bases:

  • Performance of a contract — when processing is necessary to provide our services.
  • Consent — when processing requires your prior, freely given, specific, informed, and unambiguous consent.
  • Legitimate interests — when processing is necessary for our legitimate interests balanced against your rights.
  • Legal obligation — when processing is necessary to comply with applicable law.

5. App Store & Mobile App Disclosures

  • Apple App Store. We declare our practices via App Privacy Labels. Apps using certain user data obtain consent via App Tracking Transparency before accessing the IDFA.
  • Google Play Store. We complete Google's Data Safety Form. Apps targeting Android 12+ respect the user's "Opt out of interest-based advertising" setting.
  • Other app marketplaces. Where we distribute through Huawei AppGallery, Samsung Galaxy Store, Amazon Appstore, etc., we comply with each store's privacy framework.

6. Advertising Platforms & Ad Networks

Some of our YUEJIETRADE Apps display advertising to support free versions of our products. We integrate the following advertising platforms. For each, we disclose the data accessed, the purposes, and the user controls available.

Consent first. We display advertising only after you have granted consent through the platform-provided consent prompt. You may withdraw consent at any time.

6.1 Google AdMob

We integrate Google AdMob in selected apps to serve banner, interstitial, rewarded video, and native ads. AdMob is operated by Google Ireland Limited for EEA/UK users.

  • Data: IDFA/GAID, IP, device info, coarse location (from IP), ad interactions, conversion events.
  • Purposes: ad serving, frequency capping, fraud prevention, measurement, and (with consent) ad personalization.
  • Controls: reset IDFA/GAID or enable "Limit Ad Tracking" (iOS) / "Opt out of interest-based ads" (Android). Additional opt-out: myadcenter.google.com.
  • Privacy: policies.google.com/privacy. We use IAB TCF v2.2 consent management.

  • Banner ads — standard IAB display banners displayed within the app (typically 320×50 or 300×250).
  • Interstitial ads — full-screen ads shown at natural transition points in the app.
  • Rewarded video ads — opt-in videos that reward the user with an in-app benefit on completion.
  • Native ads — ad creatives that match the look and feel of the surrounding content.
  • App open ads — ads shown when the user re-opens the app.
Frequency capping. All networks we integrate apply reasonable frequency capping. YUEJIETRADE further limits interstitial ad frequency to once per 90 seconds of active app use.

We do not use cross-site advertising cookies on our website. We do not embed third-party advertising scripts on our website.

7. Third-Party SDKs & Services

In addition to advertising SDKs, we integrate:

  • Apple frameworks — StoreKit, CloudKit (opt-in only), Sign in with Apple, App Tracking Transparency framework.
  • Google Play Services — Firebase Analytics (opt-out available), Firebase Crashlytics, Google Sign-In (opt-in).
  • Analytics. We may use privacy-respecting analytics (e.g., Plausible Analytics, self-hosted) on our website. These do not set tracking cookies or collect personal identifiers.
  • Customer support. Third-party support tools to triage and respond to your support requests. Only information you provide is shared.
  • Payment. Paid app purchases and subscriptions are processed by Apple (App Store) or Google (Play Store) under their terms. We do not directly receive payment card data.

8. Cookies & Tracking on the Website

Our website at yuejietrade.com uses a minimal set of cookies and similar technologies:

  • Strictly necessary cookies — required for the site to function (e.g., remembering your cookie consent choice).
  • Preference cookies — remembering your locale and accessibility preferences.
  • Analytics cookies — we use privacy-respecting, cookie-less analytics by default. If we ever enable third-party analytics, we will request consent first and update this Policy.

We do not use cross-site advertising cookies on our website. We do not embed third-party advertising scripts on our website.

9. Data Sharing & Disclosure

We do not sell personal information. We share personal information only in the following limited circumstances:

  • Service providers. With carefully selected service providers who process information on our behalf (hosting, support, analytics, advertising). Each is bound by a data processing agreement consistent with this Policy.
  • Legal. When we believe in good faith that disclosure is necessary to comply with applicable law, valid legal process, or government requests; to protect our rights, privacy, safety, or property; or to enforce our terms.
  • Corporate transactions. In connection with a merger, acquisition, financing, or sale of assets, with appropriate confidentiality protections.
  • With your consent. In any other case where you have given us your explicit consent.

10. International Data Transfers

YUEJIETRADE is based in Vietnam. Where personal data is transferred outside the country of the user (for example, when using US-based service providers), we rely on appropriate safeguards:

  • For EEA/UK/Swiss transfers: European Commission Standard Contractual Clauses (SCCs), the UK International Data Transfer Agreement (IDTA), or the EU-US Data Privacy Framework (where applicable).
  • For transfers from other jurisdictions: contractual safeguards consistent with local law.

11. Data Retention

  • Support emails: 24 months from last contact, unless longer retention is required by law.
  • Cloud-synced user content: retained while your account is active plus 30 days after deletion, after which it is permanently erased from production systems and within 90 days from backups.
  • Server logs: truncated IP and request metadata retained for 7 days.
  • Crash & performance telemetry: aggregated after 90 days; raw events retained for 30 days.
  • Advertising identifiers: used for the duration of the current consent and then permanently discarded.

12. Data Security

We employ industry-standard technical and organizational safeguards: TLS 1.3 encryption in transit, AES-256 encryption at rest, strict access controls, regular penetration testing, security training, and a documented incident response plan. No method of transmission or storage is, however, 100% secure; we cannot guarantee absolute security.
