Privacy Policy

ProteinFirst is provided by Jishi Consulting (Shenzhen) Co., Ltd., operating under the Jetsiv Labs brand (“we,” “us,” or “our”). This policy explains how the ProteinFirst app and website handle your information.

1. Information in the app

Content you enter or create in ProteinFirst may include food names, portions, protein amounts, daily goals, log times, and app settings. The app uses this information on your device to show logs, progress, and trends.

The current version does not upload this content to our servers or use it for third-party advertising or commercial profiling. Removing the app, clearing its data, losing your device, or moving to another device may permanently delete your local records. You are responsible for securing and backing up your device where appropriate.

2. Information you provide when contacting us

When you contact us by email or through the website, we may receive your name, email address, device type, operating system version, app version, issue description, and any attachments you choose to send. We use this information to reply, troubleshoot, and improve the product.

Please do not include unnecessary sensitive health information, identity documents, passwords, or payment credentials in support messages.

3. Website technical information

When you visit this website, our hosting and security providers may process basic technical information required to complete the request, such as your IP address, browser type, request time, and security logs. This information helps deliver the site, secure downloads, and address abuse.

4. Third-party services

This website uses Cloudflare Pages and Cloudflare R2 to deliver pages and APK files. Cloudflare may process network requests and security information under its privacy policy. If you follow a link to the App Store or Google Play, that platform handles information under its own policy.

5. How we use and retain information

We follow data-minimization principles and use received information only as needed to:

• provide and maintain ProteinFirst and its download service;
• respond to support requests and troubleshoot errors;
• protect the website, download files, and users; and
• comply with applicable legal obligations.

We retain support messages and related records only as long as needed to resolve the matter, comply with the law, or maintain reasonable business records.

6. Your choices and rights

You can view, change, or delete app records directly on your device, and you can clear ProteinFirst's local data through your system settings. For information you provided through support channels, you may contact us to request access, correction, or deletion, subject to applicable legal requirements.

7. Children's privacy

ProteinFirst is intended for general users who can manage their own dietary records. Minors should use it with guidance from a parent or guardian. We do not knowingly collect children's account information through the current app version.

8. Not medical advice

ProteinFirst is a personal tracking tool. It does not provide medical advice, diagnosis, treatment, medication management, or a personalized nutrition prescription. Ask a physician or qualified professional if you have questions about your protein goal or health.

9. Changes to this policy

We may update this policy as the product or legal requirements change. We will publish the revised version on this page and update the date above.
