Privacy Policy

Last updated: September 20, 2026

Zero-Server Privacy Guarantee

Capsule DevKit operates on a strict Zero-Server Privacy model. When you upload JSON files, images, or input API keys, all processing is done locally in your browser or passed directly to official third-party APIs (like Google, Anthropic, OpenAI) via secure edge functions. We do not store, save, or host your game assets, API keys, or localization data on our servers.

1. Information We Collect

Because of our Zero-Server model, we collect very limited information:

  • Local Storage: We may store user preferences (like selected theme or languages) in your browser's local storage to improve user experience.
  • API Keys: API keys entered into the platform are strictly passed to the respective provider's API. They are never saved to our databases.

2. Third-Party Services & Google AdSense

To keep Capsule DevKit free, we use third-party advertising companies, including Google AdSense, to serve ads when you visit our website. These companies may use information (not including your name, address, email address, or telephone number) about your visits to this and other websites in order to provide advertisements about goods and services of interest to you.

  • Third party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
  • Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to this site and/or other sites on the Internet.
  • Users may opt out of personalized advertising by visiting Ads Settings.

3. Analytics

We use Google Analytics to measure website traffic and usage. This helps us understand how our tool is being used and how we can improve it. Google Analytics uses cookies to collect anonymous traffic data.
