HydtekChess Openings Privacy Policy
This policy explains what information the Chess Openings: Learn & Quiz app for iPhone and iPad ("the app") handles and why. The app is made by Hydtek Software Inc. ("Hydtek", "we", "us"). If you have questions, email support@hydtek.ca.
The short version
- You can use the app without an account. Your progress then stays on your device.
- If you sign in with Apple or Google, we keep your progress on our servers so it survives a new phone or a reinstall.
- We never see your Apple or Google password, and we don't sell your information.
- We use Google services for usage statistics, crash reports, app settings, sign-in and ads.
Without an account
Your XP, streak, finished lessons and answers are saved in the app's storage on your device. Lessons you finish are kept in a queue on your device so they can be saved to your account if you sign in later. Deleting the app deletes all of it.
With an account
Signing in
You can sign in with Apple or Google. Sign-in is handled by Google Firebase Authentication, which receives a sign-in token from Apple or Google and gives the app an account identifier. Depending on what you allow, Apple or Google may share your email address with us; with Apple you can choose to hide it, in which case we receive a private relay address. We don't receive your password.
What we store
- Account: your account identifier, the sign-in method you used, your email address if shared, a username (we generate one, and you can change it) and your time zone, which we use to count streak days.
- Progress: each lesson or review you finish, including when you played it, which openings and question types it covered and whether each answer was right. From this we work out your XP, rank, streak and which openings are due for review.
- Sessions: for each device you sign in on, the device model, iOS version, app version, IP address, the app's user agent and the identifier iOS gives the app for that device (IDFV). We use this to keep you signed in, to let you see and sign out your devices, and to protect your account.
- Advertising identifier: only if you allow tracking when iOS asks, we store your device's advertising identifier (IDFA) and your choice. If you don't allow tracking, we store only that choice.
Your username may be shown to other players in future features such as leaderboards and friends. We'll update this policy before that happens.
Information collected by services we use
Google Firebase Analytics
We use Firebase Analytics to understand how many people use the app and which features they use. It collects app opens, sessions, time spent in the app, a few actions such as lessons started and finished, device model, iOS version, app version, language, approximate location (country or region, from your IP address) and a random app-instance identifier. Analytics data is kept for no longer than 14 months.
Google Firebase Crashlytics
If the app crashes, Crashlytics sends us a crash report so we can fix the problem: the technical details of the crash, device model, iOS version, app version, free memory and disk space, and a random installation identifier. Crash reports are kept for 90 days.
Google Firebase Remote Config
The app downloads settings from Firebase Remote Config, for example how often ads appear. This uses the same app-instance identifier.
Google AdMob advertising
The app is free and supported by ads served by Google AdMob. The Google Mobile Ads SDK may collect your device's IP address, device and app information, ad interactions, and an advertising identifier.
- Tracking permission. iOS asks whether you allow tracking. If you choose "Ask App Not to Track", your advertising identifier is not shared and ads are less personalized.
- Consent. Where the law requires it (for example in the European Economic Area, the UK and Switzerland, and certain US states), the app shows Google's consent message before personalized ads are served.
Google's use of this information is described in How Google uses information from sites or apps that use our services and the Google Privacy Policy.
How long we keep it
We keep account and progress information while your account exists. Device sessions expire after 90 days without use. When you delete your account, we delete your account, sessions and progress from our servers within 30 days.
Your choices
- Delete your account: in the app, open Settings and choose Delete Account, or email us from the address on your account. This deletes your account and progress from our servers.
- Sign out: Settings → Sign Out signs out this device. You can also sign out your other devices there.
- Username: change it at any time in Settings.
- Tracking: change tracking permission at any time in iOS Settings → Privacy & Security → Tracking.
- Requests: depending on where you live, you may have rights to access, correct, delete or export your personal information, or to object to its use. Email us and we'll respond within 30 days.
Children
The app isn't directed to children under 13, and we don't knowingly collect personal information from them. If you believe a child has given us information, email us and we'll delete it.
Where information is processed
Our servers, and Google's, may process the information described above in Canada, the United States and other countries where Google operates.
Changes
If we change this policy, we'll update the date at the top of this page. Significant changes will also be mentioned in the app's release notes.
