Gem ShopPrivacy Policy
Last updated: 22 October 2026
Gem Shop: Idle Jewelry Tycoon is a game from Itworked Systems, a company registered in Türkiye. This page explains what information the game uses, why, and who receives it. There are no accounts, and your game progress never leaves your phone.
Itworked Systems is the data controller for this information under Turkish data protection law (KVKK, Law No. 6698) and, for players in the EU and the UK, the GDPR.
- Your progress and settings are saved on your phone only. We run no game server and cannot see your progress.
- Ads only play when you choose one for a reward. Google AdMob, which shows them, starts with the game and receives device and ad information.
- Apple or Google takes any payment and confirms it to the game. We never see your card details.
- We never sell your information.
What leaves your phone, and why
| What | Why | Who receives it |
|---|---|---|
| Your device's advertising identifier (on iPhone and iPad only if you allow tracking), your IP address (used to estimate a rough location), device and app details, when the game opens, and which ads you saw or tapped | To show the reward ad you asked for, count it, limit repeats and prevent fraud. With your consent, also to make ads more relevant to you | Google (AdMob) |
| Information about how the app and its ads perform, such as load times and crashes | So ads load reliably | Google (AdMob) |
| If you buy something: what you bought, when, and the store receipt | To deliver the purchase and restore it on a new phone | Apple or Google |
Nothing else leaves your phone. There are no accounts, no sign-in and no separate analytics service.
What stays on your phone
Your game: coins, crowns, stock, machines, orders, reputation and settings, saved in the app's own storage. Deleting the app deletes them, and we cannot recover them for you.
Ads and your choices
The only ads are reward ads you choose to watch, for example to redo a step or double your income for a while. The Ad-free Workshop purchase gives those rewards without an ad.
In the European Economic Area, the UK and Switzerland, the game shows Google's consent message before any ad, so you decide whether your data may be used for personalized ads. You can change your choice at any time in the game's Settings, under Privacy choices.
iPhone and iPad: ads can only use your advertising identifier if you allow tracking when iOS asks. You can change this in iOS Settings, Privacy & Security, Tracking.
Android: you can reset or delete your advertising ID in your phone's settings, usually under Google, then Ads, or under Privacy, then Ads.
Google explains how it uses information from apps that show its ads at policies.google.com/technologies/partner-sites. Its privacy policy is at policies.google.com/privacy.
Purchases
Purchases go through Apple's App Store or Google Play, under their terms. We never see your payment details.
Why we may use this data
Ads: where the law requires consent, we rely on the choices you make in Google's consent message, and you can change them at any time. Where it does not, we rely on our legitimate interest in funding a free game with ads and in preventing ad fraud.
Purchases: to deliver what you bought.
How long it is kept
On your phone: until you delete the game.
Ad data is kept by Google under its own rules, and purchase records by Apple or Google. We have no other copy.
Where the data is processed
Google is based outside Türkiye and may process data in other countries, including the United States. These transfers follow the rules for sending data abroad in Turkish data protection law and, for players in the EU and the UK, the GDPR.
Your rights
Under Turkish data protection law (KVKK, article 11) and the GDPR, you can ask us:
- whether we process data about you, and for a copy of it;
- why we use it, and who we share it with, in Türkiye or abroad;
- to correct it, or to delete it when there is no longer a reason to keep it, and to pass that on to anyone we shared it with;
- to stop using it for a purpose you object to.
You can also object to a decision about you made only by automated analysis, withdraw your consent at any time, and claim compensation if unlawful use of your data harms you. Because your game stays on your phone, we hold very little ourselves. We will point you to Google for ad data.
Write to the address below. We answer within 30 days, free of charge. You can also complain to Türkiye's Personal Data Protection Authority (Kişisel Verileri Koruma Kurumu) or, if you live in the EU or the UK, to the data protection authority where you live.
Children
Gem Shop is not made for children under 13, and we do not knowingly process their data.
Changes
If this policy changes, we update this page and the date at the top.
