Sidera privacy policy
Effective August 7, 2026.
Sidera is a space strategy game for iOS and Android. The person responsible for your data is Ulises Monge. You can write to ulises.monge@icloud.com with any question or request about your data.
What we collect
- Account data: your email address, the commander name you choose, and your preferred language. Your password is never stored as-is: only a cryptographic hash (argon2id) is kept.
- Game data: the state of your colonies, buildings, research, fleets, reports, and the actions you take in the game, with their timestamps.
- Technical logs: like any server on the internet, ours records IP addresses and errors to operate and protect the service. If something fails inside the app, it sends us an error report: the error message, the app version and the operating system version. It does not include your account or anything that identifies you, and it is deleted after 90 days.
- Notification identifier: if you turn on notifications, we store the identifier (token) your device generates to receive them.
Notifications
If you enable them, we notify you about events in your own game (attacks, finished work, fleets). They are delivered by Firebase Cloud Messaging, a Google service that acts as a courier: it receives the notice text and your device token, solely to deliver it. You can turn each kind of notice off in the app (More → Settings → Notifications) or all of them in your system settings; when you log out, your device token is removed from our server.
How we use it
Only to run the game: signing you in, saving your progress and syncing it across your devices, and keeping the service secure. There are no ads, no third-party trackers or analytics, and we never sell or share your data with anyone.
Where it is stored
On our game server, which the app always reaches over an encrypted connection (HTTPS). Your device only stores your session credentials and preferences, inside the system's secure storage (iOS Keychain or Android Keystore).
Retention and deletion
We keep your data for as long as your account exists. You can delete your account and all of its game data directly from the app (More tab → Delete account) or by email; permanent deletion happens 30 days later, and that grace period lets you cancel it by logging in. Full instructions at Delete your account.
Children
Sidera is not directed at children under 13 and we do not knowingly collect their data.
Changes to this policy
If this policy changes, the new version will be published on this page with an updated effective date.
