Privacy Policy
Last updated: October 14, 2026
This policy explains what personal information On Sale Alerts ("we", "us") collects, how we use it, and the choices you have.
What we collect
- Account details. Your email address and password. Passwords are handled by our sign-in provider and stored only in hashed form. If you sign in with Google, we receive your name and email address from Google.
- Alert destinations. The email address and Telegram chat you add for alerts. Your alert email starts as your sign-in email until you change it.
- Your trackers. The pages you track, your filters and discount settings, and anything you type when describing what you want to track.
- Activity. When each tracker ran, what it found, how many credits it used, and which alerts were sent.
- Payments. When you buy a plan or credits, Stripe collects your card details. We never see or store your full card number; we receive your plan and payment status from Stripe.
- Technical data. Our hosting providers log IP addresses and request details for security and troubleshooting.
We keep your sign-in session in your browser's local storage so you stay signed in. We don't use advertising or analytics cookies, and we don't track you across other sites.
How we use it
- To run your trackers and send your alerts.
- To send account emails: sign-up confirmation, password resets, low-credit warnings, receipts, and notices about changes to the service or these policies.
- To process payments and keep your credit balance.
- To answer support requests, prevent abuse, and fix problems.
We don't sell your personal information, and we don't use it for advertising.
Who we share it with
We use these service providers to run On Sale Alerts. Each gets only what it needs for its part:
- Supabase: database and sign-in (data stored in the United States).
- Railway: hosting for the app.
- Anthropic: AI that reads retailer pages to find products, and turns your tracker descriptions into settings.
- scrape.do: loads the retailer pages you track.
- Resend: sends our emails.
- Telegram: delivers Telegram alerts, if you connect it.
- Google: sign-in, if you choose Sign in with Google.
- Stripe: payments.
We may also share information if the law requires it, to protect our users or the service, or as part of a sale or transfer of the business, in which case this policy continues to apply to your information.
How long we keep it
We keep your account details and trackers while your account is open. Run history is deleted after 30 days. When you delete a tracker, its alert history is deleted with it. When you ask us to delete your account, we delete your account and trackers within 30 days, except records we must keep for tax or legal reasons, such as payment records.
Your choices
- You can see and change your alert destinations in Settings, and edit or delete trackers at any time.
- You can ask us for a copy of your information, to correct it, or to delete your account by emailing [email protected]. We'll answer within 30 days.
- Depending on where you live, you may have other privacy rights. We honor these requests whatever your location.
Security
We use encrypted connections and limit who can access your data. No system is perfectly secure, so we can't guarantee the security of your information. If a breach affects your information, we'll tell you as the law requires.
Children
On Sale Alerts is for adults. It isn't directed at children, and we don't knowingly collect information from anyone under 13. If you believe a child has given us personal information, email us and we'll delete it.
Changes to this policy
We'll post any changes here with a new date, and email you about significant changes before they apply.
