Nano Mixer is a web-based AI image generation tool that uses a visual Drag & Drop Slot UI instead of text prompts. You drop reference images into slots (Identity, Outfit, Background, Pose, Prop) and the AI generates a composite result using Google Gemini.

How does Nano Mixer work?

Drop reference images into 5 semantic slots: Identity (face/model), Outfit (clothing), Background (scene), Pose (camera angle), and Prop (held object). Adjust weight sliders (0.1–1.0) per slot, add an optional text prompt, then click 'Mix It' to generate. The tool sends images as Base64 to Google Gemini 3 Pro with role-based prompts.

Yes! The free tier includes 3 slots (Identity, Outfit, Background) — enough to create complete virtual lookbooks. The Pro tier ($19 lifetime) unlocks Pose & Prop slots plus Burst Mode (3 variations at once).

Do I need my own API key?

Yes. Nano Mixer uses BYOK (Bring Your Own Key). You need a Google AI API key from Google AI Studio. Your key is stored locally in your browser and never sent to Nano Mixer servers.

Privacy Policy

Effective Date: February 27, 2026

Nano Mixer (“we,” “us,” or “our”) operates Nano Mixer and is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your choices regarding your data.

1. Information We Collect

a. Account Information (Google OAuth)

When you sign in using Google OAuth (powered by Supabase Auth), we receive and store the following information from your Google account:

Email address — used to identify your account and communicate with you.
Profile name and avatar — displayed in the UI for a personalized experience.

We do not receive or store your Google account password. We only request the minimum permissions necessary to authenticate you.

b. Uploaded Reference Images

When you use the Service as a logged-in Pro user, reference images you upload (for Identity, Outfit, Background, Pose, and Prop slots) may be stored in Supabase Storage under your account. These images are:

Private to you — protected by Row Level Security (RLS) policies that prevent other users from accessing your files.
Accessible only through your authenticated session.

c. Generated Assets (“My Studio”)

AI-generated images saved to your “My Studio” library are stored in Supabase Storage and database under your account. Like reference images, these assets are private to you and are not shared with or accessible to other users.

d. API Key

Your Google AI API Key, which you provide to use the generation feature (BYOK), is stored exclusively in your browser (localStorage). It is never transmitted to or stored on our servers.

e. Usage & Analytics Data

We may collect anonymized, aggregated usage data (e.g., page views, feature usage frequency) to improve the Service. This data is not linked to your personal identity.

2. How We Use Your Information

To authenticate you and maintain your account.
To provide, operate, and improve the Nano Mixer Service.
To store your assets and presets as part of the Pro features.
To process payments via Lemon Squeezy and verify Pro license status.
To communicate with you regarding your account or updates to our policies.

3. Payments & Financial Data

All payments for the Pro License are processed by Lemon Squeezy, our designated Merchant of Record. Nano Mixer does not collect, store, or have access to your credit card information, bank account details, or any other financial data. Please review Lemon Squeezy’s Privacy Policy for details on how your payment data is handled.

Upon a successful purchase, Lemon Squeezy sends us a webhook notification containing your Nano Mixer user ID and order status, which we use solely to upgrade your account to Pro.

4. Data Sharing & Third Parties

We do not sell, trade, or rent your personal information to third parties. We share data only with the following service providers who help us operate Nano Mixer:

Supabase — Authentication, database, and file storage.
Lemon Squeezy — Payment processing and license management.
Google (via BYOK) — AI image generation. Your reference images are sent directly to Google’s Gemini API using your own API key.
Vercel — Application hosting and deployment.

5. Data Retention & Deletion

We retain your account data and stored assets for as long as your account is active. If you wish to delete your account and all associated data, please contact us at ronbyronn@gmail.com. We will process your request within 30 days.

6. Security

We implement industry-standard security measures, including Supabase’s Row Level Security (RLS), to protect your data. However, no method of transmission over the Internet or electronic storage is 100% secure. We encourage you to safeguard your Google account credentials and log out from shared devices.

7. Children’s Privacy

The Service is not directed to individuals under the age of 18. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us immediately.

8. Changes to This Policy

We may update this Privacy Policy periodically. We will notify you of any material changes by updating the Effective Date at the top of this page. Continued use of the Service constitutes acceptance of the updated policy.
