Privacy Policy — Caterelo Deal Radar
Chrome extension · Effective: 12 June 2026 · Contact: hello@r352.com
The short version
Everything runs in your browser. We do not collect, store, transmit or sell any personal data, browsing history, or listing data.
What the extension does
Caterelo Deal Radar reads the property listing page you are currently viewing on idealista.it (price, size, condition, location text) and computes a price-fairness score locally on your device, against publicly available market benchmarks (OMI — Agenzia delle Entrate, and Caterelo engine data).
Data handling
- Listing data (price, size, location) is parsed in-page and never leaves your browser.
- Local storage (chrome.storage.local) keeps only: your Pro activation status (a yes/no flag with expiry date) and your chosen view preference (buyer/investor). No identifiers, no history.
- Network requests: the extension fetches one public benchmark file from caterelo.com (a static JSON of market price ranges). This request carries no personal data and no information about what you are browsing.
- Access codes are verified locally by cryptographic hash — the code you type is never sent anywhere.
- Deal Alerts (optional, Pro): your browser re-fetches the search result pages YOU saved, on your device, on a schedule — to detect new listings and score them locally. The list of saved searches and seen listing ids stays in local storage; nothing is sent to us or anyone else.
- No analytics, no tracking pixels, no cookies, no third-party services inside the extension.
