Privacy policy

Sunbird (“the app”) is published by Tridesetri doo Beograd, Narodnih heroja 43, 11070 Novi Beograd, Serbia — a company registered in Serbia under registration number 21720682, tax number (PIB) 112694162.

This policy explains what information the app handles and why. It is written to be read, not to be survived.

What is stored on your device

The app saves your game progress locally: high scores, daily results, firefly balance, purchased cosmetics, daily-gift streak, results on shared courses you have flown, a recording of your own best flight so you can race it, and whether you have purchased Remove Ads. This never leaves your device and is not transmitted anywhere.

None of it identifies you. There is no name, no account and nothing you have typed — the app has no field to type into.

Deleting the app deletes this data. There is no cloud backup, which also means progress does not transfer between devices.

Advertising

The app uses Google AdMob to show three kinds of ads: a small banner across the top of the menu screens, occasional full-screen ads between runs, and optional rewarded videos that you choose to watch in exchange for continuing a run. Nothing is shown while you are flying — the banner leaves the screen for the length of a flight.

To serve these, the AdMob SDK may collect and process:

• your device’s advertising identifier
• device information such as model, operating system version and language
• coarse location inferred from IP address
• information about ad interactions (impressions, clicks)

This processing is carried out by Google as an independent data controller. Google’s privacy policy governs it: https://policies.google.com/privacy

Google’s information about how it uses data from partner apps: https://policies.google.com/technologies/partner-sites

On iOS, the app asks for your permission before any tracking identifier is used (App Tracking Transparency). If you decline, ads still work — they are simply less relevant. You can change this at any time in iOS Settings → Privacy & Security → Tracking.

On Android, you can reset or delete your advertising ID in Settings → Privacy → Ads.

In the EEA and UK, you will be shown a consent form before personalised ads are used, as required by GDPR and Google’s consent policy. To change or withdraw that choice, use the device-level controls above, or contact us at office@tridesetri.com and we will help.

Removing ads. A one-time in-app purchase removes the banner and the full-screen ads permanently. The optional rewarded video for revives remains available — it only ever plays when you ask for it — so the AdMob SDK stays in the app and continues to process the information above when a rewarded ad is loaded or shown.

Purchases

The Remove Ads purchase is processed entirely by Apple or Google. We never receive or store your payment details, card number, or billing address. We receive only a confirmation that a purchase is valid, which is used to turn off the banner and the full-screen ads.

Restoring a purchase asks the store whether your account owns it. No personal information is transferred to us in the process.

What we do not do

• We do not operate a server that receives your data.
• We do not require or offer an account.
• We do not collect your name, email address, phone number or contacts.
• We do not collect precise location.
• We do not sell personal information.
• We do not use analytics SDKs beyond what AdMob requires to serve ads.

Children

Sunbird is not directed at children under 13 (or the equivalent minimum age in your country) and we do not knowingly collect personal information from them. If you believe a child has provided information through the app’s advertising, contact us at office@tridesetri.com and we will act on it.

Your rights

Because we hold no personal data on our own systems, requests to access, correct or delete data are handled as follows:

• Game progress: entirely under your control. Delete the app, or use the in-app reset, to erase it.
• Advertising data: directed to Google, which acts as the controller. Use the links above, or the device-level controls described in the Advertising section.

If you are in the EEA, UK, California or another region with statutory privacy rights, you may still contact us at office@tridesetri.com and we will help you route the request correctly.

Changes

If this policy changes materially, the updated version will be published here and the “Last updated” date changed. Continued use of the app after an update means you accept the revised policy.
