Treeling privacy policy

Last updated: October 2026

The short version

Who we are

Treeling is made by Creative Coders sp. z o.o., Warsaw, Poland, the controller of your personal data. Contact us any time at support@quorumwork.com.

Our games share one backend that we run ourselves, the Creative Coders Hub (“the hub”). This policy explains what the Treeling app and the hub process, and which partners help us.

1. Anonymous player ID

The first time the app goes online, it creates a random identifier on your device and registers it with the hub. The hub returns an anonymous player ID and a secret token. We don’t use your advertising ID, phone number, email or hardware identifiers for this.

This ID links your cloud save, friends, leaderboard scores, real-tree claims and analytics. Legal basis: providing the game you asked for (Art. 6(1)(b) GDPR).

2. Gameplay analytics

The app sends gameplay events to the hub, linked to your anonymous player ID: for example session start and length, level-ups, tutorial steps, minigame scores, quests, care actions (watering, sunshine, hugs…), purchases (product and price), watched reward videos and notification opens. Events are queued on your device and sent in batches, also after you were offline.

We use them to fix bugs, balance the game, understand which features people enjoy, and to count progress towards community goals (shared goals where everyone’s care plants real trees). Legal basis: our legitimate interest in running and improving the game (Art. 6(1)(f) GDPR). We don’t sell this data or use it for advertising.

3. Cloud save

Your game progress (trees, items, levels, settings) is saved on your device and backed up to the hub, so it survives app updates and can be merged if you play offline. If you pick a city for the weather, its name, country and city coordinates are part of your settings and therefore of this backup.

4. Friends and leaderboards

Social features are designed for players aged 13 and up, safe by design:

Legal basis: providing the features you use (Art. 6(1)(b) GDPR). We can review names and ban players from social features to keep the community safe (Art. 6(1)(f) GDPR).

5. Purchases (Apple and Google Play)

In-app purchases and subscriptions are processed by Apple on iOS and Google Play on Android. We never receive your payment card or billing details.

To deliver purchases and prevent fraud, the app sends the product ID and store transaction evidence to the hub. For Google Play this is a purchase token, verified using the Google Play Developer API; stored tokens are hashed. For Apple this includes Apple-signed transaction data (JWS), transaction and original transaction identifiers, product, purchase environment and subscription or revocation information. The hub checks Apple's signature and the app and product identifiers. Verified signed transaction data is retained for validation and recovery while the account exists; account deletion clears the signed transaction and app-account binding. Store transaction identifiers and limited purchase and delivery records may remain without the game profile. The hub records verified transactions and delivery status so a purchase is not granted twice; Apple server notifications keep subscription and refund status up to date.

Purchase events (product, price and currency) are also part of our analytics. Manage or cancel Apple subscriptions in iPhone or iPad Settings → your name → Subscriptions, or Google Play subscriptions in Payments & subscriptions → Subscriptions. Deleting Treeling or your anonymous account does not cancel a subscription or erase the store's own purchase records. Eligible purchases can be restored; spent consumables and deleted gameplay progress cannot be restored this way.

The iOS app uses Apple's Standard End User License Agreement. See also Apple's privacy policy.

6. Real trees with Tree-Nation

Real trees are planted with our planting partner Tree-Nation in reforestation projects such as Kenya Mangroves Restoration, Kenya. When you claim a real tree, the hub sends Tree-Nation the display name you type for the certificate. The hub also stores the type of your in-game tree, which may be used to choose the species planted. Tree-Nation plants the tree in the project’s next planting season and issues a certificate.

Certificates are public on Tree-Nation’s website. Please use a nickname, not your full real name. Tree-Nation’s own privacy policy applies to their website, tree-nation.com.

The hub keeps a record of your claims (type, status, certificate link) so it can show your certificates and enforce fair limits.

7. Weather and location

Real weather is optional and off by default. Without it, your tree enjoys simulated weather and the sky is estimated from your device’s time zone, on your device.

You can turn real weather off at any time in Settings. Legal basis: your consent (Art. 6(1)(a) GDPR), which you can withdraw by turning it off or revoking the permission. Weather data: MET Norway.

Nearby trees

If you turn on Nearby, the game sends an approximate location (a square of about 5 km) to our server to show other players’ trees near you. Other players see only a distance band (under 5 km, 5–15 km or 15–50 km), never your location. It is deleted when you turn Nearby off, or 7 days after the game last updated it.

Legal basis: your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time by turning Nearby off or revoking the location permission.

8. Ads (Google AdMob)

Treeling shows only rewarded videos that you choose to watch, for example for a free cure. They are capped per day. Ads are provided by Google AdMob.

Learn more: How Google uses information from apps that use its services and the Google Privacy Policy.

9. Camera and photos

Photo mode uses the camera only when you open it. Photos and timelapses are created on your device and we never upload them. If you share one, your phone’s share sheet sends it to the app you pick.

10. Notifications

Reminders (a thirsty tree, frost or a heatwave ahead, your daily gift, your streak) are local notifications scheduled on your device. No push server is involved. You can turn each type off in Settings or block them in your phone’s settings.

11. Who helps us

Some of these providers may process data outside the European Economic Area. In that case we rely on appropriate safeguards such as an adequacy decision or the EU Standard Contractual Clauses.

12. How long we keep data

13. Deleting your data

Turning off Nearby deletes your nearby square at once. Deleting your account and resetting this device turn Nearby off first.

Step-by-step instructions: How to delete your Treeling data.

14. Your rights

Under the GDPR you can ask us for access to your data, a copy of it, correction, deletion, restriction of processing, and you can object to processing based on legitimate interests. Where we rely on consent, you can withdraw it at any time. Write to support@quorumwork.com and include your friend code so we can find your anonymous player.

You can also complain to a data protection authority. In Poland this is the President of the Personal Data Protection Office (Prezes Urzędu Ochrony Danych Osobowych, UODO), ul. Stawki 2, 00-193 Warsaw.

15. Children

Treeling is not directed at children under 13, and we don’t knowingly collect personal data from them. Social features have no chat and no free text, and Nearby shows other players only a distance band, never a location. If you are below the age at which you can consent to online services in your country, please ask a parent or guardian before using online features. If you believe a child under 13 has given us personal data, contact us and we will delete it.

16. Changes and contact

If we change this policy, we’ll update this page and the date at the top, and tell you in the app if the change is important.
