Frequently asked questions

Can I use restock alerts right now?

No. The app is being prepared for re-release and the notification server is not yet running in production. There is no announced date for it.

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 Apple's own product page before ordering. The purchase and the pickup itself happen with Apple.

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

Only Apple product page URLs are accepted. A general buying page shown before you pick a colour or capacity has no specific part number, so select a configuration first and register that URL. Some products are not sold in every region, and some are not offered for in-store pickup.

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

The watch list displays Google AdMob banner ads. 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 being prepared. Registration and delivery are not yet available because the server is not connected. Once launched, choose a product URL, postal code or city and preferred stores, then allow notifications. Google Store alerts are not supported yet.

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?

Not at the moment. Both are planned, with no date. The current app is for iPhone and iPad and covers Apple Store pickup only.

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.

Full details are in the privacy policy.
