RetroGhostLabs ("we," "us," or "our") operates iOS mobile applications including PitchTunnels, PitchGuessr, and DiamondOps (collectively, the "Apps"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Apps.
Different apps in our portfolio have different data practices. Here is a plain-language summary:
Some Apps allow you to create data that is stored on your device — and, where iCloud sync is available and enabled, in your own private iCloud account. This data never reaches our servers:
When you purchase a paid app or subscription, the transaction is processed entirely by Apple through the App Store. We receive only a confirmation that a purchase was made — we do not receive your payment details, Apple ID, or billing information.
If you contact us at support@retroghostlabs.com, we receive and store your email address and the contents of your message in order to respond to your inquiry.
If you sign up for our newsletter on the RetroGhostLabs website, we collect your email address for the purpose of sending you product updates, launch announcements, and other news from RetroGhostLabs. Signing up is entirely voluntary.
Email signups are processed and stored by MailerLite, our email marketing provider. By subscribing, you agree that your email address will be stored by MailerLite on our behalf. MailerLite is GDPR-compliant. See MailerLite's Privacy Policy for details on how they handle data.
You can unsubscribe at any time by clicking the unsubscribe link in any email we send, or by emailing privacy@retroghostlabs.com with a removal request. We will process all unsubscribe requests immediately.
PitchTunnels does not use third-party analytics SDKs — see section 1.6 for details on anonymous data sent to our own backend.
When signed in via Sign in with Apple, PitchTunnels sends anonymous tunnel feedback data to the DiamondOps backend (api.diamondops.gg). This data contains no personally identifiable information (PII) and includes:
Tunnel feedback (thumbs up/down) is sent automatically when you are signed in and rate a tunnel.
Favorite reporting is opt-in only. It is disabled by default and can be enabled via a Settings toggle or a one-time contextual prompt within the app. Favorite data uses the same anonymous format as tunnel feedback with a "favorite" rating. You can disable favorite reporting at any time in Settings.
Pitcher catalog sync: When signed in, PitchTunnels fetches pitcher data from the DiamondOps backend. These are read-only GET requests — no user data is sent, only the authentication token in the request header.
When you are not signed in, PitchTunnels does not send any data to our servers.
PitchTunnels, PitchGuessr and the DiamondOps iOS app display ads to users on the free tier via Google AdMob. The Google Mobile Ads SDK and Google's User Messaging Platform (UMP) SDK, which these apps include, may collect the following information from your device:
This list follows the privacy manifests Google publishes for its SDKs (for PitchGuessr: Google Mobile Ads 13.3.0 and UMP 3.1.0). Apart from these Google SDKs, PitchGuessr's own code collects no data: your pitch tracking data stays on your device or in your own iCloud account (see section 1.1).
Google uses this data to serve relevant ads and to measure ad performance. Google may also use cookies and similar technologies on your device for ad personalization.
For more information, see:
On iOS 14.5 and later, Apple requires apps to request your permission before tracking your activity across other companies' apps and websites. Free-tier players of PitchTunnels, of PitchGuessr from version 1.4, and of DiamondOps from version 1.3, see Apple's App Tracking Transparency (ATT) prompt once, before ads start: first Google's consent form (if Google shows one for your region — see section 1.9), then the ATT prompt, and only then does the Google Mobile Ads SDK start. Lite and Pro subscribers (and Diamond subscribers in DiamondOps) are not shown the consent form or the ATT prompt. PitchGuessr versions before 1.4 and DiamondOps versions before 1.3 do not show the ATT prompt, so your IDFA is not shared with Google.
You can change this setting at any time in iOS Settings → Privacy & Security → Tracking.
If you are located in the European Economic Area (EEA) or the United Kingdom, free-tier users of PitchTunnels, PitchGuessr and DiamondOps (version 1.3 and later) are shown a consent dialog (powered by Google's User Messaging Platform) before ads are requested. Because the Google Mobile Ads SDK may also start for paid subscribers, who see no ads, Google may collect limited device and diagnostic data without showing the dialog (see section 1.11). In the dialog you can choose to:
You can withdraw or change your consent at any time. In PitchGuessr (version 1.4 and later), open Settings → Data & Privacy → Privacy Options to show Google's consent form again. In PitchTunnels (version 1.4 and later), open Help & Settings → Legal → Privacy Options to do the same; this option appears on the free tier when Google asks for a consent choice where you are. In DiamondOps (version 1.3 and later), open Profile → Support & Legal → Privacy options to do the same; this option appears on the free tier when Google asks for a consent choice where you are. You can also use your device settings. Our legal basis for processing ad-related data is consent (Article 6(1)(a) GDPR).
Some US states give residents the right to opt out of the sale or sharing of their personal information for targeted advertising. In PitchGuessr, PitchTunnels and DiamondOps (version 1.3 and later), Google AdMob can show a US state regulations opt-out message that lets residents of those states make this choice for the ads in those Apps.
Your subscription tier determines whether ads are shown:
Paid tiers see no ads. In PitchGuessr and DiamondOps (version 1.3 and later), the app confirms your subscription before deciding whether to start the Google Mobile Ads SDK, and does not start it for paid subscribers. In PitchTunnels, the app waits briefly at launch for your subscription to be confirmed; if that check has not finished in time (for example, on a slow connection), the SDK may start before your paid tier is recognized, so some of the device and diagnostic data described in section 1.7 may be collected by Google during that session. In every App, the SDK starts if a paid subscription lapses back to the free tier.
PitchTunnels users who enable "Share Favorite Tunnels" in Settings can send anonymized tunnel preference data to help improve tunnel recommendations. This data includes only tunnel IDs and pitcher context (handedness, pitch types) — no personal information is included. This feature is opt-in and disabled by default. You can turn it off at any time in Settings.
We use the limited information we collect only to:
We do not use your information for profiling or marketing without your explicit consent.
We do not sell, rent, or trade your personal information to third parties for any purpose.
Newsletter subscriber email addresses are stored with MailerLite, which acts as a data processor on our behalf. MailerLite only processes your email address for the purpose of delivering emails you have consented to receive. MailerLite does not receive any other personal information from us, and we do not authorize them to use your data for any other purpose.
PitchTunnels, PitchGuessr and DiamondOps for iOS use Google AdMob to display ads to free-tier users. AdMob receives device and ad interaction data as described in section 1.7. Google acts as a data controller for the information it collects through AdMob. No other advertising networks or third-party analytics SDKs are used in our Apps.
PitchTunnels sends anonymous tunnel feedback data to our own backend (api.diamondops.gg) as described in section 1.6 — this is not shared with any third party.
We may disclose information if required by law, court order, or government request, or to protect the rights, property, or safety of RetroGhostLabs, our users, or others.
If RetroGhostLabs is involved in a merger, acquisition, or sale of assets, your information may be transferred. We will notify you before your information becomes subject to a different privacy policy.
For Apps that store data locally (PitchTunnels, PitchGuessr), your data never leaves your device unless you choose to use iCloud sync or, in the case of PitchTunnels, sign in to enable tunnel feedback. Apple's iOS platform provides encryption for data stored on your device.
Anonymous tunnel feedback data sent by PitchTunnels is stored on DiamondOps servers (api.diamondops.gg) and is retained indefinitely for aggregate analysis. This data contains no PII and cannot be used to identify individual users.
Support emails are stored securely with our email provider. We do not store unnecessary personal information.
For Apps that store data locally (PitchTunnels, PitchGuessr), you can delete all app data at any time by deleting the app from your device. This permanently removes all locally stored data. Note that anonymous tunnel feedback previously sent to DiamondOps servers is retained for aggregate analysis but contains no PII and is not linked to your identity.
To request deletion of any support emails or communications we hold, contact us at privacy@retroghostlabs.com. We will process your request within 30 days.
You may opt out of receiving marketing emails from RetroGhostLabs at any time. Every email we send includes an unsubscribe link at the bottom — clicking it will immediately remove you from our mailing list. You can also email privacy@retroghostlabs.com to request removal. Opting out does not affect any App Store purchases, active subscriptions, or TestFlight access you may have.
You can control how ads work in PitchTunnels, PitchGuessr and DiamondOps:
Subscriptions are managed through your Apple ID. You can cancel at any time via iOS Settings > Apple ID > Subscriptions.
Our Apps are not directed at children under 13. We do not knowingly collect personal information from children under 13. AdMob is not configured with child-directed treatment (we do not tag for COPPA) as our Apps are general-audience products.
PitchTunnels' anonymous tunnel feedback data contains no personally identifiable information. If you believe we have inadvertently collected information from a child under 13, contact us at privacy@retroghostlabs.com and we will take steps to delete such information promptly.
We may update this Privacy Policy when we launch new apps or add new features. We will update the "Last Updated" date at the top of this page. Continued use of our Apps after changes are posted constitutes acceptance of the updated policy.
