Privacy Policy

Wallpaper Animator
Last updated: May 18, 2026

This privacy policy explains what data Wallpaper Animator ("the App") collects, how it is used, the legal bases on which we process it, and your rights regarding that data. The App is developed and operated by Fashtag s.r.o. (IČO: 21531854), Czech Republic ("we", "us"), which acts as the data controller under the EU General Data Protection Regulation (GDPR).

Lawful bases under GDPR Article 6. Depending on the purpose, we rely on:

1. Data We Collect

Steam ID

When you log in, we verify your identity through Steam. Your Steam ID (a unique numeric identifier) is stored on our server to manage your account and energy balance. We do not collect your email, real name, or any other personal information from Steam. On each login we also call Steam's CheckAppOwnership API to determine whether you own the full game or are running the free demo; only this true/false flag is stored.

Session Cookie

We set a single session cookie (wa_session) to keep you logged in. It is HttpOnly (not accessible to scripts), expires after 30 days, and contains only a random token — no personal data.

Usage Data

We log the following events on our server to understand how the App is used and to improve the service:

Each event is associated with your Steam ID and a timestamp. We do not share this data with third parties.

Purchase Records

When you buy energy through Steam, we store a record of the transaction (Steam order ID, package, amount, status, timestamps) so we can grant the correct energy and reconcile payments with Steam. Payment is processed entirely by Steam — we do not receive or store your payment card details, billing address, or any financial information. Your IP address is passed to Steam as part of initiating the transaction, as required by their Microtransaction API.

Feedback

If you submit feedback through the App, we store your message alongside your Steam ID in our database so we can read, categorize, and (if needed) follow up via Steam. Feedback is not shared publicly.

Generated Content

Images and videos you generate are stored on our cloud storage (Tigris S3) under your Steam ID. If you publish a wallpaper to the community gallery, it becomes publicly visible at a Tigris URL.

Local Data

The App stores your wallpapers locally in your Steam Cloud folder or in ~/.wallpaper-animator/. A log file is written to ~/.wallpaper-animator/wallpaper-animator.log and overwritten each time the App launches.

2. Content Moderation

To enforce our content policy, the App sends prompts and uploaded images to an AI moderation model before generation:

Rejected prompts and images are not stored on our servers beyond the analytics log described above.

3. Third-Party Services

We use the following third-party services to provide the App's functionality. When you generate images or videos, your text prompts and reference images are sent to these services for processing. No personally identifying information (such as your Steam ID) is sent to AI providers.

Several of these providers are based in the United States. By using the App, you acknowledge that your prompts and reference images may be processed in the United States and elsewhere outside the European Economic Area. We rely on the EU–US Data Privacy Framework or Standard Contractual Clauses, where applicable, as the legal basis for these transfers.

We may change or add AI providers in the future. This policy will be updated accordingly.

4. How We Use Your Data

5. Data Retention

6. Your Rights (GDPR)

If you are in the European Economic Area, you have the right to:

To exercise any of these rights, contact us at the email address below. We respond within 30 days.

7. Data Security

Your data is stored on servers hosted by Fly.io in the EU (Frankfurt). All communication between the App and our server is encrypted via HTTPS. Session cookies are marked HttpOnly and Secure in production.

8. Children

The App is not directed at children. We do not knowingly collect data from users below the GDPR digital-consent age in their country (16 by default, 15 in the Czech Republic). Steam's own age restrictions also apply.

9. Changes to This Policy

We may update this policy from time to time. The "Last updated" date at the top will reflect the most recent revision.
