Carissimo (“we,” “our,” or “us”) is dedicated to protecting your privacy. This policy explains how we handle information across the Carissimo website ([carissimo.io](https://carissimo.io)) and our browser extension.
A. Non-Personal Information (Automatically Collected)
1. Information We Collect
When you use the Carissimo extension, we automatically collect certain non-personal information to provide and improve our service:
Product Data: Publicly available product info (name, price, availability, images) extracted from supported retail sites.
Retailer URLs: URLs of product pages visited to track price history. This data is converted into unique, anonymized identifiers to ensure consistency without storing raw browsing history in our global database.
Usage Data & Telemetry: Anonymous usage statistics, such as a random installation ID and technical error logs, processed via Cloudflare.
B. Personal Information (Voluntary)
We only collect personal information if you choose to sign in or create an account:
Identity Data: If you sign in via Google or Email, we collect your email address and profile name to sync your watchlist across devices.
Authentication: We use Google services to securely manage your account.
2. How We Use Your Information
Price Monitoring: To maintain a crowdsourced price history database shared anonymously across all users.
Watchlist Sync: To allow you to track specific products and receive alerts on price drops.
Service Improvement: To debug errors and improve the reliability of the extension.
Affiliate Disclosure: Some links provided by the service may be affiliate links. If you purchase through these links, we may receive a small commission which helps support the development of our free tools.
3. Data Sharing and Disclosure
Anonymized Data: Product price history is shared with other Carissimo users to provide market insights. This is never linked to your personal identity.
Third-Party Services: We use Google for secure authentication and Cloudflare for technical routing and anonymous telemetry.
Legal: We may disclose information if required by law or to protect our rights.
4. Your Rights and Choices
Manage Tracking: You can disable the extension on specific domains via the Settings page.
Data Deletion**: You can delete your account and all associated personal data (email, watchlist) at any time through the extension dashboard.
Access: You can view your collected watchlist and price alert history in the dashboard.
5. Security
We use industry-standard security measures, including HTTPS encryption and secure authentication tokens, to protect your data.
