Privacy Policy — Our App

Effective date: 2026-04-07

Developer: Jian Chen (Individual Developer) (“we”, “us”)

Website/Notices: https://jianchen8863988.github.io/

1) Summary (Plain language)

No third-party SDKs, no ads, no data sharing.

No account and no cloud storage (unless this app explicitly states otherwise inside the app).

Data (if any) is processed on-device by default.

You can delete all local data anytime from the app’s Settings.

2) Data we process

Depending on features you use, Our App may process and store the following on your device only:

App settings (e.g., language preference, consent toggles)

Optional user-generated content that you choose to keep in the app (e.g., notes, session exports, drafts)

Diagnostics you provide to us (only if you email support; see Section 8)

We do not require you to provide real name, ID number, precise location, contacts, photos, microphone recordings, or health data unless a specific feature explicitly requests it.

3) How we use data

We use on-device data only to:

Provide app functionality you request (e.g., remember settings, generate outputs, show history if enabled)

Improve reliability (e.g., prevent crashes through local validation)

4) Third parties / sharing

Third‑party SDKs: None.

Advertising: None.

Data sharing/selling: We do not share, sell, rent, or trade your data with third parties.

If you later add any third-party SDK or analytics, you must update this policy and the App Store “App Privacy” answers before release.

5) Cloud / servers

Default: Our App does not upload your app data to our servers and does not provide cloud sync.

If a future version introduces optional sync or server features, it will be clearly disclosed in-app and in an updated policy.

6) Your choices & rights

Because this app stores data locally:

Delete: You can delete local app data anytime in Settings → Delete all local data (or by uninstalling the app).

Access/Export: If the app provides an export feature, you can export local data from Settings. Otherwise, there is no cloud account and therefore no cloud data for us to access or export on your behalf.

7) Data retention

We retain data only on your device, for as long as you keep it. You control retention by deleting data or uninstalling the app.

8) Support communications

If you contact us by email or phone, we will process the information you send (e.g., your email address, message content, screenshots) only to respond and support you. We do not add you to marketing lists.

9) Children

Our App is not directed to children under 13. If you believe a child has provided personal data to us via support channels, contact us and we will delete it where applicable.

10) Security

We take reasonable measures to protect data on-device, but no method of storage is 100% secure. You are responsible for securing access to your device.

11) International transfers

This app does not transfer app data to our servers. Any transfer would only occur if you choose to send information to us via support email/phone.

12) Changes to this policy

We may update this policy. We will notify users via our developer website and/or an in-app notice before changes take effect when required.
