1. Who We Are
AppScreenDesign (https://appscreendesign.com) is owned and operated by Keymaker Technologies LLC (“Keymaker”, “we”, “us”, or “our”), a United States limited liability company. For any privacy inquiry, data export request, or deletion request, contact us at hello@appscreendesign.com or accounts@keymakertechnologies.com.
2. Zero-Upload Public Browser Tools
When you use our free public utilities under /tools/—including the Screenshot Size & Alpha Checker, PNG Alpha Remover, Google Play Feature Graphic Generator, App Store Preview Simulator, Device Mockup Generator, and Panoramic Screenshot Splitter—your image files are processed 100% locally inside your web browser. No screenshots are uploaded to our servers unless you explicitly click a Studio handoff button and save a project inside an authenticated Studio workspace.
3. Information We Collect in Studio & Remote MCP
- Account & Authentication Information: When you register for AppScreenDesign Studio, we collect your email address, salted cryptographic password hash, email verification status, and active session identifiers.
- OAuth 2.1 & Remote MCP Grants: When you authorize an AI client (such as Claude, ChatGPT, Cursor, Codex, or custom MCP clients) to connect to
https://appscreendesign.com/mcp, we store OAuth 2.1 + PKCE client registrations, scoped access tokens, and audit timestamps so you can inspect or revoke agent access at any time. - Project & Screenshot Assets: We store the app captures you upload, structured
SceneDoclayout JSON, localized headline/subtitle text, and rendered PNG/ZIP output bundles strictly to provide the Studio, API, and export features you invoke. - Billing Metadata: Paid subscriptions (Pro and Scale) are processed by PCI-DSS compliant payment providers. Keymaker stores subscription tier, billing interval, invoice identifiers, and tax country, and never receives or stores full payment card numbers.
- Operational Diagnostics: Our servers record standard HTTP request metadata, rate-limit counters, and error logs necessary to keep the service reliable and prevent abuse.
4. How We Use Information & Strict AI Non-Training Policy
We use your data solely to authenticate your workspace, render and export your requested store assets, process subscription billing, send transactional account emails (such as verification and password reset links), and maintain platform security.
No AI Model Training on Customer Content: Keymaker Technologies LLC never sells your personal information and never uses your uploaded app screenshots, unreleased UI designs, brand assets, or project copy to train, fine-tune, or enrich generative AI models.
5. Shareable Live Preview Links
Projects inside Studio are private to your account by default, and /app/ is served with Referrer-Policy: no-referrer and X-Robots-Tag: noindex, nofollow. If you explicitly click “Share live preview” on an export, we generate an unguessable capability URL under /s/ (also marked noindex, nofollow) that displays the rendered panels until you revoke the share link or delete the project.
6. Cookies, Local Storage & Third-Party Processors
We use essential first-party storage and authentication tokens required to keep you signed in and pass staged files from browser tools into Studio via local IndexedDB. We do not run third-party behavioral ad networks inside Studio. Trusted infrastructure subprocessors are limited to cloud hosting/storage, transactional email delivery, and payment processing under strict confidentiality obligations.
7. Data Retention & Self-Service Account Deletion
You stay in control of your data at all times:
- Delete any uploaded capture, localization, share link, or entire project immediately inside Studio or via the REST/MCP API.
- Delete your entire AppScreenDesign account directly from your Studio account settings, which permanently purges your projects, uploaded captures, rendered exports, and active OAuth/API credentials from live storage.
- Depending on your jurisdiction (including GDPR in the EEA/UK and CCPA/CPRA in California), you have the right to access, correct, export, or erase your personal data by emailing hello@appscreendesign.com.
8. Updates to This Policy
If we make material updates to this Privacy Policy, we will update the effective date above and publish the revised text at https://appscreendesign.com/privacy/. See also our Terms of Service.
