Privacy Policy

Contagia · Developer and operator: Sudarev Daniil · Last updated: October 28, 2026

Contagia is a free game without ads. It can be played without an account, and then no personal data is collected (only the technical data described in “Services we use”). If you choose to sign in, we keep the minimum data described below, only so that your progress is not lost when you change phones. We never sell or share your data.

1. No account

The game works fully without sign-up. We do not ask for your name, email or phone number.

2. Optional account

You can sign in only with Apple or Google. Then our server (Supabase, protected by access rules) stores: your email address and Apple or Google sign-in ID (Apple lets you hide your email), a nickname, a friend code, your language and country code (taken from your phone’s region settings, not from location) and your cloud save (progress, rewards, stats). The account is shared by Sudarev games.

This data is not used for advertising or tracking and is not shared with third parties. You can delete the account and all this data in the app: “Account” → “Delete account”. Deletion is immediate and permanent and removes the cloud data of all Sudarev games; the game on your phone keeps working.

How to delete your account without the app: the page https://sudarev.app/delete-account or an email to [email protected] from the address you signed in with, subject “Delete account”. We delete it within 7 days and confirm by email. Nothing is kept.

3. Data on your device

Your settings, progress and statistics are stored only on your phone. They are not sent to us. Deleting the app deletes this data.

4. No ads or tracking

The app has no advertising and no trackers, and does not use the advertising ID. The only third-party services are listed in the “Services we use” section.

5. Permissions

The app does not ask for the camera, microphone, contacts, photos or location. Internet is needed only to sign in and sync the cloud save.

6. Children

Without an account the app collects no personal data from anyone. Accounts are intended for users aged 13 and over.

7. Services we use

Purchases. Payments are processed by the App Store or Google Play; we never see your card. To unlock what you bought and restore it on a new phone we use RevenueCat, which receives an anonymous app user ID and the purchase receipt — no name or email.

Error reports. If the game crashes or freezes, it sends a technical report through the Sentry service: game version, device model, system version and where in the code the error happened. Reports do not include your name, email, nickname or save data and are not used for advertising. You can turn this off in the game settings: “Send error reports” (or “Error reports”).

Anonymous statistics. The app can count launches with Plausible, a privacy-friendly analytics service that uses no cookies or advertising identifiers and does not store IP addresses. Nothing in these statistics identifies you.

None of these services uses your data for advertising or sells it.

8. Changes and contact

If this policy changes, the new version will be published on this page. Contact: [email protected].
