Sale Siren ("we," "our," or "us") provides a sale monitoring and alert service for consumer brands. This Privacy Policy explains what information we collect, how we use it, and your rights.
We do not sell your personal information or share your data with the brands you follow.
When you create an account, we collect your email address and authentication credentials (via Supabase). We do not collect payment information at this time.
We store the brands you follow and your alert threshold preferences. This allows us to personalize your alerts.
If you subscribe to alerts or our brief, we store your email address and may track basic delivery and open activity to ensure alerts are working properly.
We may automatically collect IP address, browser type, device information, and basic usage data (pages visited, timestamps). This data helps maintain and improve the service.
We use your information to provide sale alerts based on your selected brands, send the Weekend Brief and other service communications, improve sale detection accuracy, maintain system security, and comply with legal obligations.
We do not sell your personal information. We do not share your email address with brands you follow.
Sale Siren monitors designated brand email inboxes to detect sale announcements.
This monitoring is performed on company-controlled inboxes only.
We do not access or monitor personal user email accounts.
We use trusted third-party providers to operate the service: Supabase (authentication and database), Netlify (hosting), Render (server execution), and SendGrid (email delivery). These providers process data only as necessary to operate Sale Siren.
We retain account data while your account remains active, sale event data for analytical purposes, and email alert logs for system integrity. You may request account deletion at any time.
You may update your preferences, unsubscribe from emails at any time, or request deletion of your account.
To request deletion, contact: monitor@salesiren.sale
We implement reasonable administrative and technical safeguards to protect your information. No system can guarantee absolute security, but we take protection seriously.
Sale Siren is not intended for users under 13 years of age. We do not knowingly collect information from children.
We may update this Privacy Policy periodically. The updated version will be posted on this page with a revised date.
