Privacy Policy

Who we are

Sunday Album is a product of ArjunTech LLC. References to “we,” “us,” or “our” in this policy refer to ArjunTech LLC. You can reach us at support@arjuntech.com.

What we collect

• Account information — your email address when you create an account.
• Photos you upload — images you submit for processing. These are used solely to run the Sunday Album pipeline and are not shared with third parties except as described below.
• Usage data — job history, processing results, and basic analytics (page views, feature usage) to improve the product.
• API keys you provide — if you choose to bring your own Anthropic or OpenAI keys, they are stored encrypted and used only to make API calls on your behalf.

How we use it

• To run the photo processing pipeline and return results to you.
• To maintain your job history and library.
• To communicate with you about your account or service updates.
• To improve Sunday Album's accuracy and performance.

Third-party services

Sunday Album uses AI services to process your photos:

• Anthropic (Claude) — used for photo orientation detection. Images may be transmitted to Anthropic's API.
• OpenAI — used for glare removal via image inpainting. Images may be transmitted to OpenAI's API.

Both services process data under their own privacy policies. If you use “no-AI” mode in the Mac app or disable AI steps, no images are sent to these services.

Data retention

Processed photos and job data are retained for as long as your account is active. You can delete your library at any time from the web app. Account deletion removes all associated data within 30 days.

Mac app

The Sunday Album Mac app processes photos locally on your device. No photos leave your computer unless you explicitly enable AI steps that require an API call. No account is required to use the Mac app.
