Privacy Policy
Effective date: July 22, 2026
This page covers mobile apps published by Hequbing. We design small, focused apps that avoid accounts, ads, cross-app tracking, and unnecessary server collection.
HackerPodcasts / 机上听单
HackerPodcasts is an offline podcast listening app that organizes public podcast episode links into flight-length packs. The app does not require an account and does not include advertising or analytics SDKs.
Data stored on your device
Downloaded audio files and the download index are stored locally in the app's sandbox. They are not uploaded to servers controlled by us and are removed when you delete the app.
Network access
When you choose to stream or download an episode, the app connects directly to the podcast publisher's RSS or audio URL. We do not host or redistribute audio files. Opening Hacker News or publisher links takes you to those third-party websites, which have their own privacy policies.
In-app purchases
Apple processes in-app purchases through the App Store and StoreKit. We do not receive or store payment-card details. The app stores purchase entitlement locally through StoreKit so that unlocked packs can be restored.
Data collection and tracking
HackerPodcasts does not collect personal data, require an account, use third-party advertising or analytics SDKs, or track you across apps and websites.
Dopamine Tax Detox
Dopamine Tax Detox helps users pause before opening distracting apps. It works with iOS Shortcuts automation and stores usage-related data locally on the user's device.
Data collection
Dopamine Tax Detox does not collect personal data, does not require an account, does not run third-party advertising SDKs, and does not use cross-app tracking.
On-device data
The app may store local settings, selected app names, resistance counts, wait steps, and optional reasons written by the user. This information remains on the device and is not sent to servers controlled by us.
iOS Shortcuts
The app can be used with iOS Shortcuts automation so that a pause screen appears when the user opens a target app. Shortcut automation is configured by the user on their own device.
Sharing and retention
Because Dopamine Tax Detox does not upload personal data to our servers, we do not sell, share, or retain that data on our servers.
Children
The app is intended for a general audience and does not knowingly collect personal information from children.
SunRoom AI
SunRoom AI is designed to perform sunlight estimation on the user's iPhone. No account is required. We do not serve ads or use cross-app tracking.
Device permissions
- Camera: Used to measure the window and floor and to draw the sunlight-depth line in AR. Camera imagery is not uploaded to our servers.
- Location while using the app: Used on-device to calculate solar position. We do not retain location history or send it to servers controlled by us.
- Device orientation and motion: Used on-device to determine window direction and stabilize AR content.
Purchases and subscriptions
If an app offers purchases or subscriptions, Apple processes them through the App Store and StoreKit. We do not receive or store payment-card details.
