Privacy policy
Tsuru is a quiet puzzle game of paper cranes. This page says exactly what the app and this website do with information about you. The short version: Tsuru has no accounts, no analytics and no tracking. The only outside service that sees anything about you is the one that processes purchases.
Who we are
Tsuru is made by Mehmet Aydemir, an individual developer in Türkiye (bundle id com.koiout.game). Contact: mehmetredkan@gmail.com. In this policy "we" means Mehmet Aydemir.
What stays on your device
Your progress, your string of cranes, your settings, your wish and the notes you write are stored on your device. We do not receive them and we cannot read them. Deleting the app deletes them from the device.
What is collected, and by whom
| What | Who | Why |
|---|---|---|
| An anonymous app user id, a device identifier, and your purchase history (which products you bought or subscribed to, dates, renewal state) | RevenueCat, Inc., acting as our processor | To check what you have bought, unlock it, restore it after a reinstall or on a new device, and keep subscription state correct. Not linked to your identity: we never give RevenueCat your name or email, and there are no accounts. |
| Payment details, Apple ID, billing | Apple | Apple handles every purchase and subscription. We never see your card or Apple ID. |
| Leaderboard scores and your Game Center profile | Apple (Game Center) | Only if you use Game Center. The leaderboards are Apple's service under Apple's privacy policy. |
| Standard web-server logs (IP address, requested address, time) | Our hosting provider | When you open playtsuru.pages.dev or a crane link in a browser, the host answers the request and keeps ordinary security logs. We do not use them to identify or profile anyone. |
That is the complete list. We do not collect your name, email address, phone number, contacts, location, photos, advertising identifier or usage analytics.
Tracking, analytics and ads
Tsuru contains no analytics SDK, no tracking SDK, no advertising SDK and no third-party crash reporter. It does not track you across other companies' apps or websites and does not show the App Tracking Transparency prompt because it has nothing to ask about. Some places in the game offer a rewarded video as an optional way to earn a small thing; watching one is always your choice. If we ever add an advertising SDK, we will update this policy and the App Store privacy details before the update ships. The app keeps a small event log on your device to help the developer understand how the game plays; it stays on the device and is not sent anywhere. If that ever changes, this policy will say so first.
Sending a crane
A crane you send is encoded entirely in the link: the paper, the occasion and your note are inside the address itself. No server of ours stores the note, and there is no database of messages. Anyone who has the link can read the note, so share it only with the person you mean it for. The page at playtsuru.pages.dev/c/ decodes the link in the viewer's own browser; the hosting provider's ordinary request log (see above) can contain the link address. Do not put secrets or personal data of others in a note.
Retention
Information held by RevenueCat is kept for as long as it is needed to provide your purchases and to meet accounting and legal duties, then deleted or anonymised under RevenueCat's own schedule. Web-server logs are kept by the host for a short, rolling period. Everything else lives only on your device. You can ask us to have your RevenueCat record deleted at any time (see Your rights).
Children
Tsuru is not directed at children under 13, and we do not knowingly collect personal information from them. Because we collect almost nothing, there is little to remove, but if you believe a child has used the app in a way that concerns you, write to us.
Your rights
Depending on where you live (for example under the GDPR or Türkiye's KVKK), you may ask what we hold about you, have it corrected or deleted, object to its processing, or complain to a data-protection authority. Write to mehmetredkan@gmail.com from the device's Apple ID email if you can, and tell us the anonymous app user id shown in Settings if the app shows one. We will answer within 30 days. Subscriptions are managed in iOS Settings, not by us.
Security and transfers
The site is served only over HTTPS. RevenueCat and Apple operate internationally, so data about purchases may be processed outside your country under their own safeguards.
Changes
If this policy changes, the new version will be posted here with a new effective date. Material changes will also be noted in the app's update notes.
