Privacy Policy

Welcome to Puffx, an AI wallpaper generation app focused on a soft and tech-inspired style. This Privacy Policy explains what information we may process, how we use it, and how we protect your rights.

Puffx does not require account registration or login to use core services.

Under no circumstances do we collect facial information or any facial biometric data.

Together AI, our text-to-image provider, follows the same rule and does not collect your facial biometric information.

1. Information We Do Not Collect

To protect your privacy, we explicitly do not collect:

Any facial information or facial biometric data
Account credentials for app login (no account system required)
Personal identifiers such as ID number, passport number, or driver's license number
Financial data such as bank card details or payment passwords
Phone call records, SMS records, or contacts

2. Information We May Process

We only process limited non-personal information necessary to provide and improve services.

Prompt keywords: used only to generate requested wallpapers and show your history.
Device basics: model, OS version, app version, and resolution for compatibility optimization.
Anonymous usage metrics: used to improve feature quality and performance.
Local cache: stored on your device to speed up loading.

3. How We Protect Information

Encryption during transmission and storage where applicable
Local-first strategy for history and generated wallpaper cache
Strict internal access control and confidentiality requirements
Regular security review and vulnerability checks

4. Sharing Rules

We do not sell or rent your data. We only share necessary prompt data with Together AI to complete image generation, and this sharing is limited to service delivery.

5. Your Rights

View and delete generated wallpaper history
Clear local cache at any time
Request deletion of email feedback records submitted to us

6. Data Retention

Local records remain on your device until you delete them. Temporary server-side processing records are retained for a limited period necessary for service operation and then removed or anonymized.

7. Policy Updates

We may update this policy to reflect legal or service changes. Material updates will be shown prominently in the app.
