Privacy Policy

Last Updated: February 7, 2026

1. Information We Collect

Photos You Upload

When you generate comments, your photo is sent to our servers for processing. The image is used solely for comment generation and is not stored permanently on our servers.

Subscription Information

Payments are processed entirely by Apple through the App Store. We do not collect or store any payment card information. We receive only a transaction receipt to verify your subscription.

Local Data (on your device only)

Generation history (photos, tones, comments) is stored only on your device. We do not have access to this data.

2. How We Use Your Information

• Comment Generation: Your photo is sent to Google Gemini (our AI provider) to analyze the image and generate personalized comments.
• Crash Recovery: Generation results are temporarily cached for up to 7 days to recover from app crashes or network failures.
• Subscription Verification: Transaction receipts are verified cryptographically to confirm valid subscriptions.

3. Data Storage

On Your Device

All your data — history, photos, and generated comments — is stored locally on your device. You own and control this data.

Our Servers

Our backend is stateless. We do not maintain a database of user information. Generation results are cached temporarily (up to 7 days) in Cloudflare KV storage solely for crash recovery purposes, then automatically deleted.

4. Third-Party Services

We use the following third-party services:

• Google Gemini: Processes photos to generate comments. Google's privacy policy applies to their handling of this data.
• Apple (StoreKit 2): Processes payments and provides transaction receipts.
• Cloudflare: Hosts our backend API and provides temporary caching.

5. What We Don't Do

• We do not require user accounts or collect personal identifiers
• We do not use analytics or tracking services
• We do not display advertisements
• We do not sell or share your data with third parties for marketing
• We do not store your photos permanently on our servers

6. Your Rights

Since we do not maintain a database of user information, there is no server-side data to request or delete.

• Device Data: You can delete your generation history within the app, or delete the app entirely to remove all local data.

7. Data Retention

• Device Data: Retained until you delete it in the app or uninstall the app
• Cache Data: Automatically deleted after 7 days

8. Children's Privacy

Melt is not directed at children under 13. We do not knowingly collect information from children.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy in the app and updating the effective date.
