Privacy policy
Last updated: May 2026
This document is informational and provisional. It is not a definitive legal document. Definitive terms will be published before public launch.
1. MVP version: no accounts or database
In the current MVP version, Existence Compiler has no account system, login, or user database. No personally identifiable data is collected.
2. Local storage (localStorage)
Generated reports are stored exclusively in the user's browser via localStorage. This data remains on the user's device and is not sent to or stored on Existence Compiler servers. Users can delete this data by clearing their browser's local storage.
3. URL analysis
When a user enters a URL for analysis, the system makes an HTTP request to that URL from the server. This is equivalent to any normal crawler visit. The analyzed content is not stored in proprietary databases.
4. AI semantic enrichment (optional)
If the user configures an AI provider API key (such as Anthropic), part of the analyzed content (text, metadata, site structure) may be sent to the configured provider to generate semantic enrichment. This transmission is subject to the privacy policy of the respective provider. Existence Compiler does not store user API keys in the frontend.
5. Cookies
Existence Compiler does not use tracking or advertising cookies. User language preference is saved in localStorage, not cookies.
6. Third-party services
The site may load fonts from Google Fonts. If AI is used, requests go to the configured provider. We do not use third-party analytics tools in the MVP.
7. Policy changes
This policy may be updated. We will publish significant changes on this page with the update date.
