Privacy

StickerCheck privacy policy

StickerCheck has no account and no sign-in. Your scans stay on your iPhone.

Effective October 12, 2026. StickerCheck is published by Heeseong Kim (“we”).

On your iPhone

Your scan history, tag photos and settings are kept in the app and in your device backups. You can delete them in Settings → Clear Scan History or by deleting the app.

Checking a price

To check a tag, the app sends the tag photo and the product’s details (such as its name, model number, barcode and price) to our service. Photos are not stored. Product details and prices may be kept for a short time so later checks of the same product are faster; nothing about you is stored with them. Before others see those prices, our service opens the store listings they link to and keeps only the prices the listings still show.

Anonymous usage and crash data

The app sends anonymous information about how checks go and crash reports, to fix problems and improve the app. It carries no name, account, device identifier or advertising identifier, and is deleted after 60 days.

Feedback you send

When you send feedback from the app (Settings → Send Feedback, or Report a Wrong Price or Link under a check’s prices), we receive your message and the topic you picked, the app and iOS version, your iPhone model and your country. If you leave Include This Check on, the report also carries the product from that check and the prices and links it showed. Feedback carries no name, email or account, so we can’t reply to it. We keep it for one year and share it only with the people who build StickerCheck, through our team’s messaging workspace.

Price drop alerts

If you turn on price drop alerts, the app sends us your iPhone’s push notification token and, for each product you check (up to 30, each for 60 days after you last check it), its name, barcode or model, the words we search stores for, the shelf price you saw and the lowest online price you were shown. We use them only to check the stores about once a day and notify you when a price drops. The first time, we send your iPhone a silent notification that shows nothing, to confirm the token belongs to a real iPhone. Turning alerts off in Settings or deleting a scan removes them right away. If you delete the app, they are removed the next time we try to notify you, and in any case when the 60 days end.

Ads

StickerCheck shows ads from Google AdMob. Google may collect your device’s advertising identifier (only if you allow tracking when asked), IP address, approximate location and information about the ads you see, to show and measure ads. You can change tracking any time in iOS Settings → Privacy & Security → Tracking. See how Google uses this data.

Purchases

Remove Ads is sold through Apple. We never see your payment details.

• We don’t sell or share your personal information.
• We don’t ask for your name, email, contacts or precise location.
