Welcome to BendSnap (the "App"). The App is developed and operated by Yanling Technology ("we", "us"). We take your privacy seriously and treat the protection of your personal information as a top priority. This Privacy Policy explains how we collect, use, store, and protect your information.
Please read this Privacy Policy carefully before using the App. By starting to use the App, you are deemed to have read and agreed to the entirety of this Policy. If you do not agree with this Policy or any of its terms, please stop using the App. If you have any questions about this Policy, you may contact us at iptton@gmail.com.
This Privacy Policy helps you understand:
1. How we collect and use your information;
2. How we store and protect your information;
3. How we share, transfer, and disclose your information;
4. System permissions;
5. Your rights;
6. Protection of minors;
7. Updates to this Policy;

BendSnap is a conduit-bending calculator. Its core functions (bend calculations, history, preset management, spirit level) run entirely on your device. We collect as little of your information as possible:
When you perform calculations, save history or presets, or configure custom bender parameters in the App, this data is stored in your device's local storage. This content is stored only on your device and is never uploaded to any server; we cannot and do not intend to access it.
The App offers a one-time in-app purchase, "Pro Unlock", which unlocks advanced features such as unlimited presets. The purchase process is handled by Google Play. When you initiate a purchase, Google Play processes your payment and manages the related transaction information according to its own privacy policy. The App itself does not collect, store, or transmit any information related to your payment or account. After a purchase is completed, the App records your entitlement status locally only to unlock the corresponding features.
When you use the "Spirit Level" feature, the App temporarily reads your device's accelerometer data to display the tilt angle in real time. This sensor data is read and displayed only while the spirit level is active; it is never saved, transmitted, or uploaded, and reading stops as soon as you leave the spirit level screen.
The App follows the principles of "data minimization" and "local first":
- Your calculation history, presets, and bender configurations are stored on your device locally using Android's DataStore mechanism;
- The App does not provide any account system and does not collect any personally identifiable information;
- Apart from the payment flow handled by Google Play when you initiate a purchase, the App does not communicate with any server, and your data never leaves your device;
- In-app purchase entitlement is determined by querying the Google Play servers; the App only caches this status locally for feature gating and does not involve your personal data;
- When you uninstall the App, all locally stored data is permanently deleted.
Because the App does not collect or upload your personal information, we do not sell, rent, or share your information with any third party. We may disclose relevant information as required by law in the following circumstances, but such disclosure does not involve the data you created in the App:
1. Directly related to national security or defense security;
2. Directly related to criminal investigation, prosecution, trial, and judgment enforcement;
3. Necessary to protect the vital lawful interests of you or other individuals where it is difficult to obtain consent;
4. Other circumstances stipulated by laws and regulations.
The App does not request any system permissions (such as microphone, storage, location, or network). All calculation functions are performed locally on the device and require no additional authorization. The in-app purchase feature relies on the existing authorization of Google Play services and does not involve the App requesting any additional system permissions.
Because your data is stored entirely locally, you have full control over it:
- Right of access: You may view all your saved calculation history and presets in the App at any time;
- Right to deletion: You may delete any calculation record or preset at any time, and deleted data cannot be recovered;
- Right to restore purchases: If you change devices or reinstall the App, you may resync your purchased entitlement from Google Play via "Restore Purchase" in the App;
- Right to complete erasure: After uninstalling the App, all local data is permanently deleted.
We attach great importance to the protection of minors' personal information. The App does not actively collect minors' personal information, and the content provided is suitable for the general public. If you are the guardian of a minor and have any questions about the minor's use of the App, you may contact us via the contact information at the end of this Policy.
We may update this Privacy Policy from time to time. After an update, we will update the effective date on this page and may notify you via in-app prompts or other means. If the update involves a material change (for example, adding a feature or third-party integration), we will obtain your consent again.
If you have any questions, comments, or suggestions about this Privacy Policy, or wish to exercise your data rights, you may contact us as follows:

We will verify your identity and respond as soon as possible after receiving your request.

本应用提供一次性内购项目"Pro 解锁"，用于解锁无限预设等高级功能。购买流程由 Google Play 处理。当您发起购买时，Google Play 会处理您的支付，并由 Google 根据其自身的隐私政策管理相关交易信息。本应用本身不收集、不存储、不传输任何与您支付或账户相关的信息。购买完成后，应用仅在本机记录您的已购权益状态，以便解锁对应功能。
当您使用"水平仪"功能时，本应用会临时读取设备的加速度传感器数据，用于实时显示设备的倾斜角度。这些传感器数据仅在水平仪功能开启期间被读取并实时显示，不进行任何保存、传输或上传，您离开水平仪页面后即停止读取。
本应用遵循"数据最小化"和"本地优先"原则：
- 您的计算记录、预设、弯管器配置使用 Android 系统提供的 DataStore 机制保存在设备本地；
