Unaided - Privacy Policy
Last updated: 2026-11-13. This policy covers the Unaided Android app and its optional online service.
The short version
- You can play everything without an account. As a guest, your progress stays on your device and our server stores nothing about you.
- If you create an account, we store your email, display name and game progress so you can sync and appear on the Daily leaderboard.
- The free version shows ads from Google AdMob, which may process your device's advertising ID and device data under Google's policies.
- Optional purchases (removing ads, hint packs) are handled entirely by Google Play. We never see your payment details.
- If you use Google Play Games, your progress can be saved to your Play Games account (stored by Google, not by us).
- Anonymous, first-party usage statistics and crash reports help us improve puzzles and fix bugs. You can turn them off in Settings.
- We never sell your data. You can delete your account and all its data at any time.
Data we store when you have an account
| Data | Why |
|---|---|
| Email address | Sign-in and account recovery. We do not send marketing email. |
| Password | Stored only as a salted Argon2id hash; we cannot read it. |
| Recovery code | Shown to you once; stored only as a hash. |
| Display name | Shown on the Daily leaderboard. Choose any name; it need not be your real name. |
| Game progress | Solved levels and their sparks, best effort, move logs used to verify solutions, hint wallet history, achievements, the dates you played, Daily scores. |
| Session tokens | Kept signed in. Stored as hashes; they expire after 60 days of inactivity. |
| Security log | Failed sign-ins, password recovery and account deletion, with a salted hash of the IP address (never the address itself). Kept for 180 days. |
Anonymous usage statistics
The app may send events such as app opened, level started/completed/quit, hint opened, Daily completed and ad watched, with details like the level id, time taken, hints and mistakes. They are tied to a random install id that we hash before storing; they are never linked to your account, email or IP address, and are deleted after 90 days. They go only to our own server - no third-party analytics SDK. You can opt out at any time in Settings.
Crash reports
With the same setting on, the app sends a short report when it hits an error: the error type and message (with email addresses and long numbers removed on your device), the program stack trace, whether the app closed, the app and Android version, and the screen or level you were on. Reports use the same hashed install id, are never linked to your account or IP address, go only to our own server, and are deleted after 90 days.
Advertising (Google AdMob)
The app uses Google AdMob to show rewarded and interstitial ads. AdMob may collect and process your device's advertising ID, IP address, approximate location, app interactions and diagnostic data for advertising, analytics and fraud prevention, as described in How Google uses information from sites or apps that use its services. Where required (for example in the EEA and UK) the app asks for your consent first, and you can change your choice later under Settings → Privacy settings. You can reset or delete your advertising ID in your Android settings.
Purchases (optional)
You can buy "Remove ads" (a one-time purchase that ends the ads between puzzles and adds a few hints) or hint packs. Payment is handled entirely by Google Play under Google's Privacy Policy; we never receive your card or payment details. The app keeps the Google Play order number of each purchase in your hint wallet so a purchase is only ever counted once; if you have an account, that order number is part of the wallet history we store. "Remove ads" belongs to your Google account and is restored automatically on a new phone (Settings → Restore purchases).
Google Play Games (optional)
If you use Google Play Games on your device, the app can sign you in to it automatically. It then saves a copy of your game progress (levels, sparks, hints, Daily results and achievements) to your Play Games saved games, and mirrors your achievements to Play Games, so your progress follows you to a new phone. This data is stored by Google in your Google account under Google's Privacy Policy; our server never receives your Play Games identity. You can manage or delete Play Games data in the Google Play Games app or at your Google Account, and you can play without Play Games at any time.
Where and how long
Account data is stored on our server and encrypted in transit (HTTPS). Backups are kept for up to 14 days. Data is kept while your account exists and deleted when you delete the account (backups roll off within 14 days).
Deleting your account
In the app: Settings → Account → Delete account. On the web: https://unaided.choicetechai.com/account/delete. Deletion is immediate and permanent and removes your email, profile, progress, wallet, achievements and leaderboard entries.
Children
Unaided is not directed at children under 13 and we do not knowingly collect their personal data.
