Frequently asked questions

Can I use restock alerts right now?

You can add products and allow notifications in the iOS and Android apps and on the web. Alerts are sent when stock changes from unavailable to available, or back again. The iOS app is available on the App Store. The Android app is available on Google Play. Delivery depends on device or browser settings, connectivity and stock data availability.

If the app says a product is available, can I definitely buy it?

No. Availability is shown as of the moment it was checked, and stock changes after that. Always confirm on the official Apple Store or Google Store product page before ordering. Purchases, pickup and delivery are handled by the respective store.

Which countries and regions are supported?

You can choose from the 27 countries and regions that have Apple retail stores. Store lookups have been verified at representative locations in 25 of them, which is not a guarantee that every store, product or postal code works. In Brazil and Macau, pickup availability cannot currently be retrieved this way.

A product won't register

iOS 3.1.0 and later and the web accept Apple Store and Google Store product URLs. After loading the URL, select a configuration such as color and storage. For Apple, also select a pickup area and stores. Some products or configurations are unavailable in a region or are not supported by the availability check.

I want fewer ads, or I want to change my consent choices

The paid iOS and Android apps contain Google AdMob ads. The web app uses Google AdSense. Consent is checked where required, and an ad privacy options entry is shown in the app settings when applicable so you can change your choices. Use of the iOS advertising identifier (IDFA) requires iOS tracking permission; declining it does not prevent you from using the core availability features. See the advertising section of the privacy policy for details.

Can I receive alerts from the website?

A web alerts page is available. Add an Apple Store or Google Store product URL, choose a configuration and allow notifications. For Apple, also choose a postal code or city and preferred stores. Google Store checks the online availability of the selected configuration, not retail store stock.

On iPhone or iPad with iOS or iPadOS 16.4 or later, use Share → Add to Home Screen and open the new icon. Device and browser settings may prevent delivery.

The web page lets you pause or delete each watch and delete all registration data under Registration and data for this browser. Do this before clearing cookies. Registrations do not sync between browsers or apps.

Is there an Android version, or Google Store availability?

iOS 3.1.0 and later and the web support Apple Store pickup and Google Store online stock for your chosen configuration. Android also supports these features. Google Store offers 24 sales regions; support for every product and configuration is not guaranteed.

Deleting your data

You can delete saved products from within the app, and stopping alerts stops the corresponding monitoring and any pending notifications. However, that alone does not erase all server records.

To have information stored on the server deleted, write to info@cavemen.jp. After confirming which records are yours, we delete the device notification registration, the monitoring settings and the delivery processing records. Please tell us your country or region and what you would like removed. Again, do not put private keys or authentication secrets in email.

Monitoring settings and delivery records are not automatically erased when monitoring is paused or a product is removed; they remain until a deletion request is confirmed. Records in backups are not immediately removed by that request, and no automatic backup deletion deadline is currently configured. Shared product catalog information that is not linked to an individual remains.

Full details are in the privacy policy.
