this privacy policy describes how pongsixtyfour studios ("we", "us", "our"), operated by Pongsixtyfour Studios LLC of North Carolina, USA, handles information in connection with the figured series of apps - currently Crossums and Sequences (the "apps") - distributed on the Apple App Store and Google Play. apps outside the figured series are covered by their own policies.
1. summary
our apps are designed to collect as little information as possible. neither app requires an account, runs ads, or includes third-party analytics or advertising SDKs. we do use a crash reporting service to help us find and fix bugs - see section 2.
2. information we collect
data you provide. if you email us for support, we receive your email address and the contents of your message so we can respond.
on-device data. puzzle progress and settings are stored on your device. on iOS, progress is also synced through your personal iCloud account. we cannot access data stored in your personal cloud account.
automatically collected data. the apps do not collect usage analytics, use advertising identifiers, or track you across other apps or websites. if the app crashes or hits an error, we use Sentry to automatically send us a crash report - this can include the type of error, a stack trace, and technical details like your device model, OS version, and app version. we configure Sentry not to store IP addresses or user identifiers. this data is used only to diagnose and fix problems, not to track your activity or for advertising.
3. how the app stores are involved
the apps are sold and delivered through the Apple App Store and Google Play. when a purchase is made, Apple or Google processes the payment and provides us with purchase records. their handling of your data is governed by Apple's Privacy Policy and Google's Privacy Policy.
4. how we use information
- to respond to support requests and feedback you send us;
- to diagnose and fix problems you report;
- to comply with legal obligations.
we do not sell your personal information, and we do not use it for advertising.
5. sharing
we do not share personal information with third parties except: (a) service providers acting on our behalf under confidentiality obligations - currently email hosting and Sentry for crash reporting; (b) when required by law; or (c) to protect our rights. purchases are handled directly by Apple and Google (see section 3), not by a separate payment or subscription service.
6. data retention
support correspondence is retained only as long as needed to help you and to keep reasonable records, then deleted. on-device data is removed when you delete the app or clear it in-app. on iOS, progress synced through your personal iCloud account stays in that account until you delete it there; we cannot access or delete it for you. on Android, if device backup is on, a copy of your progress may be kept in your Google account backup and restored when you reinstall or set up a new device; it stays there until you delete the backup. crash reports sent to Sentry are automatically deleted after 30 days.
7. children
our apps are designed for players of all ages, including children. neither app has accounts, shows ads, or uses an advertising identifier.
if an app crashes or hits an error, a crash report is sent to Sentry. it contains technical information only: the device model, OS version, app version, and a stack trace. we configure Sentry not to store IP addresses or user identifiers, we use crash reports only to find and fix bugs, and they are automatically deleted after 30 days (see section 6).
a parent or guardian can email support@pongsixtyfourstudios.com to ask what information we hold about their child or to have it deleted. we respond as described in section 8.
8. your rights
depending on where you live (for example under GDPR or CCPA), you may have the right to access, correct, or delete personal information we hold about you, and to object to certain processing. to make a request, email us at the address below. a parent or guardian may make a request on behalf of a child. we will respond as required by applicable law.
9. security
we use reasonable technical and organizational measures to protect information under our control. no method of transmission or storage is completely secure.
10. changes to this policy
we may update this policy from time to time. we will post the revised version here and update the "last updated" date above. material changes will be indicated clearly.
