Help for Corner Grocer: Market Sim on iPhone. If your question is not answered here, write to support@birkinapps.com.

Email support@birkinapps.com. In the Game you can also open Settings > About > Contact support, which starts an email to the same address.

If something is broken, please tell us. The more of this you include, the faster we can find the cause:

  • What you were doing, what you expected and what happened instead.
  • The Game version, shown in Settings > About.
  • Your iPhone model and iOS version.
  • Your Player ID, shown in Settings > Account. It lets us find your records without asking for anything else.
  • For a VoiceOver problem: what VoiceOver said and what you expected it to say.

Please do not send passwords or card numbers. We never need them.

  • The Game is free to download. Coin packs and the one-time support packs (Starter, Supporter and Founder) are optional in-app purchases. The Shop shows what each one contains before you buy.
  • Apple takes the payment through your Apple Account and gives the Game a receipt that our server checks. Your card and payment details never reach us.
  • Apple decides refund requests. You can ask at reportaproblem.apple.com. When Apple refunds a purchase, the Coin it gave are taken back; if you had already spent them, your Coin balance can go below zero until you buy enough to bring it back to zero.
  • A purchase has not arrived? Check your connection, then use Restore Purchases (next section). If it is still missing, email us with the date of the purchase and your Player ID.
  • In the Game, open the Shop and choose Restore purchases at the bottom, or open Settings > Purchases. It brings back the one-time packs you bought before, for example on a new iPhone.
  • Apple cannot restore Coin. Your Coin balance is kept on our server with your account, so it comes with your account.
  • For now your game progress is kept on your device only. Your Coin and the packs you own are kept on our server with your account.
  • Before you change phones, open Settings > Account and link an Apple or Google account. It is optional and your game on this device stays as it is. If you lose or change your phone without linking one, a guest account and the Coin and items on it can be lost, and we may not be able to restore them.
  • Coin is only for sound and looks: atmospheres, music, end-of-day tunes, customer voice packs, decor and outfits. It never makes the Game easier or harder. Accessibility features and Assists are always free.
  • You can buy Coin, and you can earn it in the Game by finishing daily goals, reaching milestones and watching an optional ad (see Ads).
  • Coin has no value outside the Game, cannot be exchanged for money and cannot be given to other players. Coin you bought does not expire.
  • The Game can show two kinds of ads, provided by Google AdMob.
  • Optional ad for a reward. In the Shop Studio, a button can offer a short ad in return for Coin. In the evening report, a button can offer a short ad too: in version 1.0.2 and earlier it gives Coin; from version 1.0.3 it doubles that day’s shop profit instead, once a day. The button tells you the reward and how many you have left today. If the ad cannot load, or you close it before the end, you get no reward and the try is not counted.
  • Full-screen ad between game days. It can appear after you choose Next day (currently from day 3; the timing can change). It can appear for all players, including players who use a screen reader such as VoiceOver, unless you own an ad-free pack. With VoiceOver, the Game announces when an ad starts, and that its Close button is usually in a top corner, and announces again when the ad closes.
  • There are never ads while a game day is running, at a work station, in the pause menu or around a purchase. Full-screen ads give nothing. The only rewards are the ones the optional ads above state: Coin in the Shop Studio and, in the evening report, Coin (version 1.0.2 and earlier) or doubled shop profit for that day (version 1.0.3 and later).
  • To remove ads, see Ad-free packs. For your choices about personalised ads, see Privacy choices.
  • The Starter, Supporter and Founder packs each remove full-screen ads. They are one-time purchases in Shop > Support. From version 1.0.3 they also give every new shop extra starting cash.
  • If you own one of them, the Game never shows you a full-screen ad, and you get the optional-ad reward without watching an ad: the Coin in the Shop Studio and, from version 1.0.3, the doubled evening shop profit too.
  • There is no separate remove-ads-only purchase, and ads cannot be removed with Coin. On a new iPhone, bring a pack back with Restore Purchases.
  • Magic Tap (double-tap with two fingers) pauses and resumes the game day. In the morning it opens the shop, and in the evening report it starts the next day. At a station it only pauses, so a payment is never taken by accident.
  • Two-finger scrub (the VoiceOver Escape gesture, a Z drawn with two fingers) goes back: it leaves a station, cancels a page or dialog without confirming anything, and goes back in Settings. On the shop map during a game day it pauses.
  • Speech level. Settings > Speech level sets how much the Game says: Full, Balanced or Sounds First. It changes only what is spoken, never the rules or the score.
  • Assists and Easy mode. Settings > Difficulty and assists lets you pick Easy, Normal or Custom. Assists change pace and protections, not the rules: for example, on Easy customers wait longer and goods cannot go on the wrong shelf. Assists and Easy mode are free for everyone.
  • If something does not work well with VoiceOver, please tell us (see Report a bug).

The voices of the customers are generated with artificial intelligence; they are not recordings of real people. In Settings > Customer voices you can set them to Off, Low or Normal.

  • In the Game, Settings > Privacy > Share usage data is on by default. When you turn it off, the Game stops sending analytics events and stops updating your player profile on our server. Crash reports are separate and keep working.
  • Choices about personalised ads are in Settings > Ads > Ad privacy options (it opens Google’s form, where it applies) and in iOS Settings > Privacy & Security > Tracking.
  • The details are in the Privacy Policy.
  • In the Game, open Settings > Account and choose Delete account.
  • On the web, Delete your data explains the same steps, what is deleted and what is kept, and how to ask by email if you no longer have the Game.

iPhone with iOS 15 or later. The Game is available in English and Turkish.
