Privacy Policy

Last updated: May 27, 2026

OneBottle is a privacy-first sustainability application designed to help you identify and recycle plastic bottles. We do not require account registration, we do not store your personal information, and all core processing happens with your data under your control.

What Information We Collect and Why

OneBottle is built to minimize data collection. Below is a transparent breakdown of every data interaction in the app.

a. Camera Access

Purpose: Capture images of plastic bottles for identification and recycling guidance.

Data use: Camera frames are processed in real-time for rectangle detection using Apple's on-device Vision framework. No images are saved to your photo library unless you explicitly choose to do so.

Storage: No local or remote retention. Camera data is transient and discarded after processing.

b. Image Recognition via AI Services

Purpose: Identify bottle type, material, and provide recycling instructions.

Data use: When you capture a bottle image for AI analysis, the image is transmitted over TLS-encrypted connections to our secure proxy server (Tencent Cloud SCF), which forwards it to Alibaba Cloud Bailian (qwen-vl-max-latest) for one-time visual recognition. Recognition results are returned immediately.

Storage: Images are not stored on our servers. They are processed in-memory and discarded immediately after recognition completes. Neither Tencent Cloud SCF nor Alibaba Cloud retains your images beyond the duration of a single API request.

c. Local Processing

Purpose: All other app functionality operates entirely on-device.

Data use: Bottle recognition results, recycling history, and preferences are stored locally on your device using standard iOS storage mechanisms. Nothing is uploaded to any server.

Storage: Data remains on your device only. You can clear it at any time by deleting the app.

What We Do Not Collect

Third-Party Services

OneBottle uses the following third-party services solely for the purpose of image recognition:

We do not use any analytics SDKs, advertising networks, crash reporting tools, or user tracking frameworks.

Data Security

Even though we do not store your personal data, we implement industry-standard security practices:

Children's Privacy

OneBottle is designed to be safe and appropriate for users of all ages. Since we do not collect personal information, require account registration, or display advertisements, the app is suitable for children without additional parental consent requirements.

If you are a parent or guardian and believe your child has shared personal information through the app, please contact us immediately. We will investigate and ensure any such data is removed.

Policy Updates

We may update this Privacy Policy from time to time to reflect changes in app functionality, legal requirements, or operational practices. When we make material changes, we will notify you through in-app notices. Continued use of OneBottle after an update constitutes acceptance of the revised policy.
