Privacy Policy

Melwa · Effective Date: August 12, 2026

1. Information We Collect

To provide Melwa’s core service — transforming your photos into style mystery box images — we may collect:

• Photos or short videos you upload or capture for generation (camera or photo library).
• Optional profile data such as display name and avatar you set in the app.
• Device identifiers, including identifiers used for sign-in / account continuity and advertising measurement identifiers described in Section 3 (for example Device ID, IDFA when authorized, and Adjust advertising ID / ADID).
• Purchase records related to in-app Coin top-ups processed by Apple (including purchase event tokens used for attribution measurement).
• Usage and attribution data needed to operate generation, Collection, Coin balance features, and marketing measurement (for example install source, campaign / network / creative labels when available).

Photos are used to generate mystery box results and are not intended to be permanently stored on our servers after processing is complete.

2. How We Use Information

We use collected information to:

• Provide AI style generation and mystery box results;
• Maintain your Collection, Coin balance, and profile locally or as needed for the service;
• Process consumable in-app purchases;
• Measure app installs, campaign performance, and related marketing attribution;
• Improve product stability and user experience;
• Protect account security and prevent fraud or abuse.

We will not sell your personal information. We may share limited identifiers and event data with measurement partners as described below so we can operate advertising attribution.

3. Advertising Measurement, Device ID, and Third Parties

Melwa integrates the Adjust SDK (Adjust GmbH / Adjust Inc.) for mobile advertising measurement and install attribution. This is a third-party advertising / analytics measurement service. Melwa does not operate as an ad network that shows third-party display ads in the core photo-generation experience, but we use advertising measurement tools to understand which campaigns brought users to Melwa and to measure related in-app events (such as registration, login, and purchases).

In connection with Adjust and our own servers, we may process:

• Device ID / advertising identifiers — including Apple’s Identifier for Advertisers (IDFA) when you grant App Tracking Transparency (ATT) permission, Adjust’s advertising identifier (ADID / adid), and other device-level identifiers needed for attribution and anti-fraud;
• Attribution and campaign data — for example network, campaign, adgroup, creative, click / impression labels, and related metadata returned by Adjust;
• Event data — limited product events such as install, registration, login, and purchase value / token used for measurement.

These data may be transmitted to Adjust and to Melwa’s backend attribution interfaces so we can attribute installs, evaluate advertising performance, and reduce fraudulent attribution. Adjust processes data under its own terms and privacy policy: https://www.adjust.com/terms/privacy-policy/.

On iOS, access to IDFA for cross-app tracking is controlled by Apple’s ATT prompt. You can change tracking permission later in iOS Settings → Privacy & Security → Tracking. If you deny tracking, Melwa and Adjust may still perform limited, non-IDFA measurement permitted by the platform (for example Adjust ADID or aggregated attribution), subject to Apple’s rules.

Where required, Melwa discloses in App Store privacy labels that Device ID and advertising / usage data may be used for Developer’s Advertising or Marketing and/or Third-Party Advertising measurement, and that tracking may occur when you authorize it.

4. AI Processing

To create your mystery box image, Melwa sends the photo (or a still frame from a short video) you select and your Style Blueprint prompt to cloud AI image services for processing. Processing is temporary and used only to generate your result. Melwa does not sell your photos. You retain ownership of your uploads and generated results, subject to applicable law and the Terms of Service.

On first generation, Melwa presents an AI Privacy Notice describing this processing and ownership.

5. Storage and Protection

We employ industry-standard security technologies and measures to protect your information from unauthorized access, use, or disclosure. Generated results and related media may be stored on your device as part of Collection and save/share features. Attribution identifiers and event logs may be stored by Melwa and by Adjust for measurement and security purposes for as long as needed for those purposes or as required by law.

6. Permissions

Depending on how you use Melwa, the app may request:

• Camera — capture photos or short videos as source media for AI transformations;
• Microphone — record audio when you capture a short video as source media;
• Photo Library — select photos or short videos for generation and save results to your album;
• Tracking (ATT) — allow Melwa / Adjust to access the advertising identifier (IDFA) to measure advertising campaigns and attribute installs across apps and websites owned by other companies, subject to your choice.

You can manage permissions in iOS Settings.

7. In-App Purchases

Coin purchases are processed by Apple. We do not receive your full payment card details. Purchase status may be used to credit Coins in Melwa and may be reported as a measurement event to Adjust for advertising attribution.

8. Data Retention and Deletion

You may delete your account in Profile → Delete Account. Doing so permanently clears your Collection and remaining Coins on the device as described in the app. Some records required for fraud prevention, advertising measurement, or legal compliance may be retained as required by law or by our measurement partners’ retention schedules.

9. Children’s Privacy

Melwa is not directed to children under 13. If you believe a child has provided personal information, please contact us so we can take appropriate action.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The Effective Date above will be revised when changes are published. Continued use of Melwa after updates constitutes acceptance of the revised policy.
