Privacy Policy
Last updated: October 24, 2026
The short version: we keep only what we need to watch prices for you: the store, item, price, date and order number of things you add. We never read your inbox, never store your receipt photos or emails, never sell your data, and show no ads. You can delete your account and everything in it from the app at any time.
Snagback ("we", "us") is an iPhone app and website at snagback.app, run by Vital Kyungu. This policy covers both. Questions: [email protected].
What we collect
- Your account. The email address you sign in with. If you use Sign in with Apple and choose "Hide My Email", we only get Apple's private relay address. We don't collect your name.
- Purchases you add. Store, item name, SKU or model number, price paid, order date, order number, and (if you tell us) your store membership tier. If you paste a product link, we keep the link.
- Prices we look up. The current price of each item, checked once a day, and when we checked it.
- Your wins. Amounts you tell us you got back, with the item and store.
- Your personal forwarding address (like [email protected]), so emails you forward reach your account.
- A push notification token for your phone, so we can send drop alerts.
- Basic in-app events, such as "price drop found" or "subscription screen viewed", tied to your account. We use them to understand whether Snagback works, for example how many people get money back. We don't use third-party analytics or advertising SDKs, and we don't track you across other apps or websites.
- Waitlist. If you join the waitlist on our website, your email address and the date you joined.
What we don't keep
- Receipt photos. When you snap a receipt, the photo is sent to our server, read, and discarded. It is never saved.
- Forwarded emails. When you forward an order email, we read the order details from it and then discard the email. We don't keep its text.
- Names, addresses, phone numbers and card numbers. We remove these from anything we read before saving.
- Your inbox. We never ask for access to your email account.
- Payment details. Subscriptions are handled entirely by Apple. We never see your card.
How we use it
- To track each purchase's price-adjustment window, check prices, and alert you when a price drops.
- To help you claim (for example, writing the message to send the store).
- To show your money-recovered history.
- To run your account and subscription, provide support, and keep the service secure.
- To email you sign-in codes and, if you joined the waitlist, news about the Snagback beta and launch.
We don't sell or rent your personal information, and we don't use it for advertising.
Who helps us run Snagback
We use a small number of service providers, who may only use your data to provide their service to us:
- Supabase: our database, sign-in and servers.
- Anthropic: its Claude AI reads receipt photos and forwarded order emails to pull out the purchase details. Under Anthropic's commercial terms, this content isn't used to train its models.
- Postmark: sends sign-in emails and receives the order emails you forward.
- Apple: Sign in with Apple, in-app subscriptions, and delivering push notifications.
- Expo: passes our push notifications on to Apple.
- RevenueCat: keeps track of subscription status (no payment details).
- Cloudflare: hosts this website and handles email for snagback.app.
- Best Buy: we look up current prices using Best Buy's product API. We send only product numbers (SKUs), never anything about you.
We may share information if the law requires it, or to protect the rights and safety of our users and Snagback.
How long we keep it
- Purchase details are deleted automatically 30 days after the store's price-adjustment window closes.
- Your wins (amounts you got back) stay in your history until you delete your account.
- Your account stays until you delete it.
- Waitlist emails stay until you ask us to remove them, or until we stop running the waitlist.
Your choices
- Delete your account anytime in the app: Settings → Delete my account. This permanently removes your purchases, wins, forwarding address and sign-in. (It doesn't cancel an Apple subscription; do that in your iPhone's Settings → your name → Subscriptions.)
- Stop notifications in your iPhone's Settings → Snagback → Notifications.
- Leave the waitlist or ask for a copy of your data by emailing [email protected]. Depending on where you live, you may have other rights over your data; contact us and we'll help.
Security
Data is encrypted in transit and stored with access controls so each account can only reach its own records. Secret keys stay on our servers, never in the app. No system is perfect, but we work to keep your information safe and keep as little of it as we can.
Children
Snagback isn't meant for children under 13, and we don't knowingly collect their information.
Changes
If we change this policy, we'll update the date at the top. For important changes, we'll let you know in the app or by email.
