1. About this policy
This policy applies to the Android app Arenis: Sand Sort Challenge and this page. The game is independently developed by Renan Alves. Use the contact at the end for privacy questions and requests.
You can play without creating an Arenis account. Ads and sync depend on Google service availability. Sync is optional and may be unavailable in development versions.
2. Data stored on your device
The app stores progress, stars, best move counts, one ongoing game per difficulty, undo history, revealed colors and locks. It also stores language, theme, accessibility, audio, completed tutorials, sync preference and a local ad counter.
These records let you resume games, keep your preferences and control ad frequency. We do not operate our own server to receive ongoing games or preferences.
3. Advertising and Google data
Arenis uses Google AdMob. Its SDK processes IP addresses (including for approximate location), advertising/device and, where applicable, account identifiers; app/ad interactions; and diagnostics. Purposes include advertising, measurement and fraud prevention. SDK transmissions use TLS. See the SDK disclosures and Google’s Privacy Policy.
The game displays banners and interstitials at transitions after results. Ads do not grant rewards. The game code does not request camera, microphone, contacts or precise location access.
4. Your advertising choices
Google’s User Messaging Platform (UMP) checks which choices must be presented based on region and consent status. Where applicable, you can accept, decline or manage purposes and partners.
Where available, reopen your choices under Settings → Account and privacy → Ad privacy. Android also provides advertising identifier controls. Declining personalization does not necessarily remove ads. Learn more at how Google uses data.
5. Optional Play Games sync
If the feature is available and you enable Sync progress in Account and privacy, Google Play Games authenticates your Google Account and stores a copy of completed results. Google also handles account and technical data needed for its service under Google’s Privacy Policy.
The copy sent by Arenis contains level identifiers and revisions, rules version, stars and best move counts. It excludes ongoing games, undo history, preferences and the ad counter. Turning sync off stops new app sync operations, but does not delete previously stored copies or sign you out of your Google Account.
6. When you contact us
If you send a support or privacy message, we process your email address and the information you provide to respond and resolve the request. Send only what is needed; do not send passwords or identity documents without a previously explained need.
7. Retention and deletion
Local data remains until you clear Arenis storage in Android settings or uninstall the app. This removes local games and preferences; it does not automatically delete data held by Google.
To remove cloud progress, turn off sync in Arenis and follow the Play Games deletion instructions. To prevent uploading it again, also remove the local copy before enabling sync again. Deletion may permanently remove stars and best scores.
Contact messages are kept as needed to handle requests and meet applicable obligations. Google and GitHub retain their service data under their own policies; we do not promise retention periods or deletion outside our control.
8. Requests and rights
Use the contact on this page to ask about data handling or request access, correction, deletion and other rights available under applicable law. Requests are assessed considering data under our control and any need to verify that the request is legitimate. Also use Google’s own controls for data in your Google Account.
9. External services and security
Google provides ads, consent and, when enabled, sync. GitHub hosts this page. These services may process data outside your country under their own policies and safeguards. We do not publish your individual results on this page.
We use measures appropriate to the app, such as files in its private storage and official SDKs. No system is entirely immune to failures; do not share sensitive information in unnecessary requests.
10. Children and teenagers
Arenis is a general-audience game. The game does not ask children or teenagers for their name, email address or identity documents to play. Parents and guardians can contact us about data use or requests concerning information under our control. Google services are also subject to their own age conditions and settings.
11. This page
This page includes no ads, forms, analytics tools, third-party scripts or remotely loaded fonts. The hosting provider may log IP addresses and technical request information to operate and protect its service. See GitHub’s Privacy Statement.
12. Changes and contact
We may update this policy as the app and its services change. The date above identifies this version. Changes requiring a new choice will use appropriate app mechanisms. Contact the developer at support.arenis@gmail.com.
